Korea’s T-50 Family Spreads Its Wings

Iraqi, US, Israeli & Polish opportunities; ROKAF places 1st FA-50 order. (Jan 4/12)

Korea’s defense industry is advancing on all fronts these days. On the armored vehicle front, vehicles like the XK2 tank and K9/K10 self propelled howitzer are beginning to win export orders, and its XK-21/KNIFV amphibious infantry fighting vehicle may not be too far behind. All fill key market niches, promising performance at a comparatively inexpensive price. Its shipbuilding industry, one of the world’s busiest, is beginning to turn out LHDs, and December 2008 saw its first-of-class KDX-III AEGIS destroyer accepted into service on time and on budget. Now its aerospace industry is in flight abroad with the already-exported KT-1 trainer. Not to mention a clever entry into an incipient market.

Enter the T-50 Golden Eagle family, which offers a supersonic high-end trainer and light fighter aircraft at an attractive price. The aircraft is hitting the international market just as many of the world’s jet training fleets are reaching ages of 30 years or more, and high-end fighters are pricing themselves out of reach for many countries. The TA-50 LIFT variant and FA-50 lightweight fighter are especially attractive as lightweight export fighters, and the ROKAF’s own F-5E/F Tiger II and F-4 Phantom fighters are more than due for replacement. Now the key question for the platform is whether it can find corresponding export sales…

T/F/A-50: The Planes

The T-50 was developed by Korea Aerospace Industries, Ltd., with cooperation and global marketing support from Lockheed Martin. Both firms were aware that many training aircraft fleets are aging, even as higher-performance fighters demand trainer aircraft that can keep up. The Korean government needed a fleet of trainers, and saw an opportunity to give their aerospace sector a strong boost in the process. Total investment in the T-50’s RDT&E program amounted to more than $2 billion: 70% from the Korean government, 17% from KAI, and 13% from Lockheed Martin.

With a length of 43 feet and a wingspan of 30 feet, the 2-seat T-50 is about 4 feet shorter than the F-16; overall, it’s only about 80% of the F-16’s size. The relative size of the control surfaces and tails are larger, however, to improve handling characteristics at lower speeds and make the aircraft easier to land. Larger landing gear is also fitted, to absorb harder landings, which is to be expected from student pilots. Its form’s resemblances to Lockheed Martin’s F-16 are suggestive, and include the blended mid-set wing, complete with leading-edge root extensions and rear ‘shelf’ fairings ending in F-16-style split airbrakes. The air intake layout on the sides is somewhat similar to the F/A-18 Hornet or Northrop’s excellent but ill-fated F-20A Tigershark, and the aircraft is powered by the same engine: GE’s popular, reliable and fuel-efficient F404, with slight improvements over the F404-GE-402 to enhance single-engine redundancy and reliability.

The T-50 trainer carries a basic navigation / attack system, which gives it some multi-role capability. The aircraft can carry Sidewinder missiles on the wingtips, as well as fuel, rockets, or qualified bombs on its 5 underwing and center pylons. the center pylon and 2 inner underwing pylons are “wet,” and can accommodate 150 gallon fuel drop tanks.

The T-50 family’s empty weight is 14,000 pounds, and maximum takeoff gross weight is 29,700 pounds; the F404-GE-102 engine produces 17,700 pounds of thrust. Maximum rate of climb is 39,000 feet per minute; and the maximum speed is Mach 1.5. Service ceiling is 48,500 feet, the design load factor is 8gs, and the trainer airframe is designed for up to 10,000-hour service life (8,344 hours for the A-50).

Still, the plane is designed to be a trainer, with better rear visibility than a 2-seat F-16. An “active stick” ensures that stick movements in the front or rear are transmitted to the stick in the other seat, to improve monitoring and learning. Embedded training features, in-flight recording and post-mission debriefing capability are all built in. The standard tools of a modern fighter pilot’s trade are likewise present: “glass cockpit” of digital screens, HUD (Head Up Displays), HOTAS (Hands On Stick And Throttle) control systems to keep everything at the pilot’s fingertips, triple-redundant electrical system, fly-by-wire, advanced radio and navigation systems including INS/GPS, and a Martin-Baker zero-zero ejection seat. The seat back angle is 17 degrees – similar to the seat angles of the F-35 Joint Strike Fighter and the F/A-22.

Per the standards for modern trainers, the aircraft is part of a larger, integrated training system that includes simulators, computer-based training, cockpit and maintenance trainers, and a training management system.

Maintenance has also received careful thought. The new trainer’s airframe will require no mandatory depot maintenance, and the aircraft boasts a “single-tier design” with some 250 access panels allowing technicians to get at any major system without having to remove any others. Extensive self-diagnostics will help keep maintenance costs down.

All in all, the T-50 may remind some people of the F-16 that was originally designed by the “Fighter Mafia” back in the 1970s, when they were busy breaking every big-jet, multi-role, high-priced rule the USAF had cultivated for over a decade. Its thrust/weight ratio ensures that it’s no F-16; even so, 25 years after the F-16 was entering service, it retains one more comparison point: a similar price point in absolute dollars. A $20 million price point in the modern era places it firmly on the high end for a trainer, but its supersonic performance and versatility could still make the T-50 very popular indeed.

Key market competitors include the subsonic BAE Hawk, Aermacchi’s now-supersonic M346, and its Russian twin the Yak-130.

At present, 3 variants of the T-50 are planned, beyond the basic T-50 trainer aircraft.

One is the T-50B aerobatic variant, which has replaced the ancient A-37 Dragonflys flown by South Korea’s “Black Eagles” national aerobatic team.

The 2nd is the TA-50 lead-in fighter trainer (LIFT) variant. It adds Lockheed Martin’s AN/APG-67v4 multi-mode radar, derived from the radar that equipped Northrop’s F-20 Tigershark. It also has provisions for radar warning receivers and specialty pods, sports a 3-barreled M61 20mm cannon, and can carry Sidewinder air-air missiles, rocket pods, AGM-65 Maverick missiles, and Mk80 family bombs. If the specialty pods have surveillance and targeting capabilities, it is likely that laser-guided bombs and rockets could be added to their arsenal.

A slightly more expensive variant called the F/A-50 will be fitted for the lightweight fighter and light attack roles, and can also serve in the lead-in fighter trainer (LIFT) role alongside the TA-50. It will have a wider range of equipment, but is hobbled by a key limitation.

The F/A-50 is also a joint KAI/ Lockheed Martin project, and the associated agreements includes a number of restrictive terms. One is that Lockheed will not transfer aircraft source code to other nations. Another is that the T-50’s capabilities cannot exceed Korea’s F-16s, though proposals to give the KF-16s AESA radar retrofits could break that logjam. A 3rd provision banned South Korea from integrating T-50 variants with non-U.S. technology that the United States doesn’t have.

Instead of Selex Galileo UK’s Vixen 500E AESA radar, therefore, the first F/A-50s will use IAI’s popular EL/M-2032 multi-mode radar, installed by Lockheed Martin. It will be coupled to additional datalinks like Link-16, a weapons management system, radar warning receivers, and a MIL-STD-1760 databus. FA-50s will also be able to carry additional electronic countermeasures equipment, and specialty pods like LITENING or Sniper ATP for targeting, surveillance, etc. Weapons will include the same lightweight 3-barreled M61 20mm gun, AIM-9 Sidewinder air-air missiles, rockets, Mk80 family bombs, and AGM-65 Maverick missiles carried by the TA-50. The enhanced radar, databus, and related systems will expand the FA-50’s range of potential weapons by adding GPS-guided weapons like JDAM bombs, WCMD cluster bombs, JSOW glide bombs, etc. They’re also likely to enable the addition of AIM-120 AMRAAM air-air missiles, anti-ship missiles, and other advanced armaments.

Any FA-50 exports to Arab countries would have to use the AN/APG-67v4 radar and Sniper-SE surveillance and targeting pod from Lockheed, however, as the Israeli-designed radar and LITENING pods will not be an option. As advanced AESA radars become more mainstream in the global military market, the lack of an AESA option is also likely to cost the F/A-50 orders, unless KAI and Lockheed Martin come to an agreement. Proposals to upgrade the ROKAF’s KF-16s with AESA radars could offer a way out of the impasse.

T/F/A-50: The Program

The Republic of Korea Government authorized the go-ahead of the T-50 development program in October 1997, after the completion of the conceptual design in which started in 1992. The Full Scale Development Program was successfully completed in January 2006.

KAI is the prime contractor, and is responsible for the design of the fuselage and tail unit, final assembly of the aircraft, and design of the accompanying training systems. The mid-mounted variable camber wings are manufactured by Lockheed Martin, who is also responsible for the avionics and fly-by-wire flight control system, and provides technical consulting.

The production line at Saechon is designed for a 1.5-aircraft-per-month production capability with a single shift, but the assembly process can produce up to 2.5 aircraft per month by simply adding another shift if orders increase. Man Sik Park, director of the T-50 management team at Sacheon, adds that “Getting more customers than our line can currently handle is no problem because we can increase the production rate further with additional tools and assembly jigs.”

The ROKAF already has production orders for 102 of KAI’s aircraft: 50 T-50 trainers, 22 TA-50 LIFT/ light fighters (with an option for another 22), 10 T-50B aerobatic aircraft that replaced the Black Eagles’ A-37 Dragonflys, and 20 FA-50s. Further domestic orders may follow in 2013 for 40-110 more upgraded FA-50 variants, to replace the RoKAF’s F-5 Tiger II and F-4 Phantom fighters.

Outside South Korea, Lockheed Martin Aeronautical Systems and KAI have created the T-50 International Company (TFIC) to pursue export markets. Indonesia (16 TA-50/T-50i) remains the only export customer so far.

The FA-50 in particular will offer performance that competes favorably with likely competitors such as the Chinese/Pakistani JF-17, and India’s Tejas LCA. All 3 of these jets are likely to find themselves competing in the niche once occupied by a pair of 1960s-1970s era competitors – Russia’s MiG-21s, and Northrop’s amazingly popular F-5, which still flies with the ROKAF. Both aircraft types are still flying in many air forces, and both are reaching the end of their lifespan. Hence the market opportunity. Unlike its Chinese and Indian competitors, however, the F/T/A-50 family’s secondary fighter trainer role makes it attractive to first and second world air forces as well.

Contracts & Key Events

Jan 4/12: FA-50 Ordered. Flight International reports that South Korea has placed a $600 million order for 20 FA-50 fighters. This is the 1st order for the new type, and KAI will reportedly deliver the aircraft from 2013 – 2014.

So far, Flight International is the sole source for this report. South Korean orders could eventually swell to over 100 FA-50s, as the ROKAF seeks to replace its F-5E/Fs. This could also help in competitions like Poland’s, by broadening KAI’s in-production T-50 family technology options.

Nov 22/11: AESA for KF-16s? Raytheon declares that it is “responding to the Republic of Korea’s official launch of the F-16 radar upgrade competition with the Raytheon Advanced Combat Radar system (RACR).” RACR is designed as a drop-in AESA radar for F-16 fighters, and is based on the technologies in the AN/APG-79 radar that equips US Navy Super Hornets.

No word yet on other competitors, but any KF-16 AESA upgrade could break a technology logjam for the FA-50 as well.

Oct 28/11: Poland. Poland steps back from its existing trainer & light fighter RFP, and says it will re-do the competition. They seem to have been surprised at the cost of meeting their previous specifications, and will opt for a trainer with lower combat capabilities in the next round. That means the new jets won’t really be able to replace their SU-22s, but it also means that, in the words of deputy defense minister Marcin Idzik, Poland won’t “be the sole country to acquire such an [aircraft as we had requested].” This implies that even the TA-50, which looked to have good odds of winning the bid, was insufficient.

The new RFP is expected in spring 2012. Read “Poland Seeks Advanced Jet Trainers/ Light Fighters” for full coverage.

Oct 10/11: Israel. The Jerusalem Post reports that KAI has formally partnered with Lockheed Martin in its bid to sell T-50 trainers to Israel, citing the advantage of being able to use American military aid funds. That possibility has been a live option since September, but this makes it official.

In Israel, KAI is once again competing against Alenia’s M-346 Master. Italy has reportedly made an interesting barter offer, and the 2 countries built close ties under Prime Minister Berlusconi. Israel’s final choice will be a significant geopolitical decision – read “Trainer Jets for Israel: Skyhawk Scandal Leads to End of an Era” for a full explanation, and ongoing coverage.

Sept 15/11: US FACO? The Korea Herald reports that Lockheed Martin is setting up a T-50 final assembly and check-out (FACO) plant in the USA. That makes perfect sense as it competes for the USA’s pending T-X trainer competition, and it also affects Israel’s buy. If the T-50 series can be considered an American product, that means Israel could buy it with American foreign aid dollars. The M-346 is unlikely to be able to offer that, which would give the Korean jet a significant edge.

The existing T-50 Golden Eagle contract reportedly states that KAI takes 70% percent of the production work, while Lockheed takes the rest.The firms would not address speculation that this ratio might be adjusted for the US T-X and /or Israeli competitions.

June 2011: Iraq. Jane’s Defence Weekly reports that the Iraqis may have made an oil-for-aircraft deal to buy Korean T-50 family jet trainers, some of which could also serve as effective light fighters. If so, this indicates serious budget issues, and makes the reported deal for Aero Vodochody L159T jet trainers questionable. Will the L-159’s potential Iraq deal become yet another canceled Czech?

As of Jan 5/12, however, no public announcement had been made regarding either platform.

May 26/11: KAI IPO. If KAI seemed to jump the gun on the Indonesia announcement, there may be a clear motive. The Korea Exchange has just approved an IPO for the firm to go public, which is expected to raise around $525 million in cash for the firm. Announcing the sale just ahead of that approval is permissible, and has the effect of boosting the expected asking price. Woori Investment & Securities, and Hyundai Securities, will manage the deal. Reuters | Wall St. Journal.

May 25/11: Indonesia win. Well, that was fast. KAI executive VP Enes Park is quoted as saying that the Indonesian Defense Ministry signed a $400 million deal for 16 jets – or $25 million per plane, which is not the deep discount deal touted earlier. Aviation Week says that the contract reportedly involves a T-50 with a gun and weapon pylons (i.e. TA-50), though the actual designation is T-50I.

The planes will replace about 10 Hawk Mk.53 subsonic trainers, and may also supplement or replace the TNI-AU’s 5-6 remaining F-5E/F fighters. Read “Indonesia Looking for Trainer/Attack Aircraft” for full coverage.

May 20/11: Indonesia win? In the wake of an ROK-Indonesian agreement to expand economic and industrial cooperation via a joint secretariat, and reports that KAI has been designated as Indonesia’s preferred trainer jet bidder, Indonesia’s Amir Sambodo suggests that Indonesia might buy 16 T-50 family jets, in exchange for 4 or more additional CN-235 aircraft bought from Indonesia’s Digiranta. Read “Indonesia Looking for Trainer/Attack Aircraft” for full coverage.

April 12/11: Indonesia. The Indonesian government sends a letter to KAI, designating the South Korean firm as the preferred bidder to replace Indonesia’s BAE Systems Hawk 53s. Source.

Feb 24/11: UAE stall. Flight International reports that M346 negotiations between the UAE and Alenia Aermacchi have stopped, with no word on when they might resume. Having said that:

“The door appears to remain closed to KAI and the T-50, with officials from the South Korean company agreeing. “Obviously, we would love to get back into the competition and offer the T-50. But we have not had any discussions with the UAE officials about the T-50 since they picked the M-346, and we are not expecting that to change any time soon,” says a KAI official.”

That quote would seem to contradict recent reports by UPI and Defense News, which said that the UAE had re-opened talks.

Jan 24/11: TA-50. South Korea rolls out the first production TA-50 variant, with light attack capabilities. The TA-50s will mostly be used to train new military pilots on air-to-air and air-to-surface missions before they deploy to KF-16s or F-15Ks, but they can also perform combat missions themselves as secondary air patrol or ground attack assets, and ould be asked to do that in the even of a war.

South Korean media report that TA-50 deliveries will continue until 2012, to be followed by full F/A-50 fighters from 2013 onward. Korea Herald | idomin [in Korean, picture]

Oct 25/10: Iraq Czeched? Prague Monitor and Iraq Business report that the Czech Republic might sell up to 25 used Aero L-159s to Iraq. Iraq has been holding a competition for 24 jet trainers between Korea’s T-50, the UK’s Hawk, and Italy’s M-346.

If the L-159 has become a focus, rather than just a competitor, it’s likely that the price of new jet trainers was too high, given other pressing needs – and that Iraq is now looking at value over newness. Time will tell.

Sept 28/10: Singapore loss. Rumors of a loss in Singapore are confirmed, via a EUR 250 million contract to supply Singapore with 12 M-346 trainers and related systems. The win comes via Alenia’s global marketing agreement with Boeing, who already supplies Singapore’s new F-15SG fighters. Read “Finmeccanica’s M-346 AJT: Who’s the Master Now?” for full coverage.

Sept 2/10: Poland RFP. Poland’s Ministry of Defense (MON) issues its jet trainer RFP for 16 planes, plus support, related training systems like simulators; and initial training for 6 instructors, 6 pilots, and 50 ground crew. 1.45 billion zlotys (about $467 million) has been budgeted, and the T-50 is a contender.

Aug 9/10: Indonesia finalists. Air Forces Monthly reports that Indonesia’s Defense Acquisition Program Administration has narrowed its 16 plane advanced jet trainer and light attack aircraft shortlist to the Czech Aero L-159B, South Korea’s T-50 Golden Eagle, and Russia’s Yak-130.

That leaves both Alenia’s M346 Master and China’s JL-9/FTC-2000 out in the cold. Interestingly, the common denominator for the 2 eliminated types is poor secondary ground attack capabilities.

July 1/10: Singapore loss? Defense News reports that Singapore’s government has selected Alenia Aermacchi’s M-346 as the preferred bidder in its $1.3 billion competition for 48 advanced jet trainers. Aermacchi teamed up with Singapore’s ST Aero to compete against the KAI-Lockheed team, with Boeing providing the ground-based training system to support the M-346.

Singapore’s MINDEF has not made its decision public, and neither KAI, nor Aermacchi, nor South Korea’s Defense Acquisition Program Administration (DAPA) procurement and export agency could confirm the tip. The report adds that the UAE’s M346 deal remains in limbo over a side deal to develop UAVs together, which may give the T-50 an opening. Singapore’s loss in particular is a sharp blow to the platform, however, and may set other events in motion – including privatization:

“The state-owned Korea Development Bank (KDB) announced in April 2009 that it would sell its 30.5 percent stake in KAI, which has three other major local shareholders – Samsung Techwin, Doosan Infracore and Hyundai Motors, each with a 20.54 percent stake. But KDB temporarily withdrew from its decision in the face of opposition from KAI’s labor union, which argued that the privatization effort could hurt overseas sales of the T-50…. Earlier this year, a KoFC(Korea Finance Corp.) official said, “If KAI fails to sell the T-50 to Singapore, discussions of the KAI privatization would certainly be resurfaced. Our position will be re-established after that.”

May 12/10: The ROKAF holds a ceremony to celebrate the delivery of the 50th T-50 jet. KAI.

April 6/10: SFW for TA-50s. Textron Defense System announces that the ROKAF will integrate their Sensor Fuzed Weapon (SFW) smart cluster bombs on the FA-50 light combat aircraft. Through a foreign military sale led by the Eglin Air Force Base Air Armament Center and the Defense Acquisition Program Administration of South Korea, Textron Defense Systems expects to begin providing inert integration rounds starting in 2010.

Oct 29/09: AESA offered. Flight International reports that Raytheon officials are touting their RACR model AESA radar for the F/A-50 at the 2009 Seoul air show. Northrop Grumman’s similar SABR radar, which has been designed to compete with RACR in the F-16 retrofit market, is another possibility. Buying an American radar would step around the provisions that F/A-50 source code may not be shared with other countries; whether it would also overcome the agreements’ other obstacles remains to be seen.

Sept 23/09: EL/M2-2032 radar deal. Israel Aerospace Industries announces a $280 million pair of contracts with South Korea, one of which covers EL/M-2032 radars for the TA-50 and F/A-50 fighters. The fighter radar will be co-produced by IAI ELTA and South Korea’s LIG Nex1.

The other order reportedly involves Israel’s Oren Yarok (“Green Pine”) long-range air defense and missile tracking radar. Earlier discussions had revolved around figures of about $215 million for 2 Green Pine radar systems, and current reports offer a figure of $200 million for an undisclosed number of systems. The low number of TA-50 and F/A-50 fighter orders at this early stage of their development, and the EL/M-2032 fighter radar’s low R&D needs given its mature state, makes those figures plausible in the absence of a detailed breakout between the 2 contracts. Globes adds that IAI’s usual contract policies involve a down payment of 25-35%, suggesting that it will record $70-98 million revenue from these contracts in its consolidated financial report for 2009.

The release and follow-on reports do not mention South Korea’s KF-16s, which are also slated for a radar upgrade that reportedly involves IAI ELTA. IAI release | Globes business | Agence France Presse | Flight International.

Sept 21/09: Israel. Flight International reports that Alenia Aermacchi’s M-346 Master and the Korea Aerospace Industries/Lockheed Martin T-50 have emerged as the leading candidates to replace the Israeli Cheyl Ha’avir’s TA-4 Skyhawk advanced jet trainers. See also full DID coverage: “Israel’s Skyhawk Scandal Leads to End of an Era.”

Aug 2/09: Israel. As reports of Israeli radar cooperation to equip KAI’s TA-50 and FA-50s swirl around the media, Israel has sent a formal delegation to evaluate and test-fly the T-50 as a potential replacement for its Skyhawks. This is the first time in 40 years that Israel is considering purchasing a fighter jet not made either locally, or in the United States.

Israeli newspaper Ha’aretz reports that other candidates include the T-45 Hawk variant, and Alenia’s M-346. Media reports currently cite the T-50 family as the front-runners for the 20-30 plane Lead-In Fighter Trainer order. Read “Trainer Jets for Israel: Skyhawk Scandal Leads to End of an Era” for ongoing coverage.

July 23/09: IAI radar. The Korea Times reports that South Korea’s LIG Nex1 will sign a deal with Israel’s IAI Elta Systems on Sept 3/09. That deal will involve the first phase of development for an indigenous radar based on the EL/M-2032 mechanically scanned phased array radar, to equip TA-50 and F/A-50 aircraft.

An official from the ROK’s DAPA procurement agency told the Times that the radar is expected to be built by the end of 2010, and enter service in 2011. In the mid- to long-term, sources told The Kora Times that the domestically-built radar is likely to be installed on upgraded KF-16 fighters. The Times adds that the effort may even lead to Korean development of an active electronically scanned array (AESA) radar under future agreements with IAI Elta, who has also developed the EL/M-2052 AESA.

The South Korean Air Force is buying 50 T-50 trainers, 22 TA-50s with secondary attack capabilities, and 10 T-50Bs modified for aerobatics; and is expected to add 60 F/A-50 light fighters by 2012 to replace its F-5 Tiger and F-4 Phantom fighters.

April 30/09: Black Eagles switch. The ROKAF’s Black Eagles acrobatic flight display team retired its Cessna A-37 Dragonflys after the 2009 Seoul Air Show. The ROKAF announces that they will re-debut with a fleet of 8 T-50B Golden Eagles at Seoul’s international air show in October 2009. Note that the final Black Eagle paint scheme ended up being different than the initial scheme depicted in the photo, above.

This will make the Black Eagles one of the few air force aerobatic teams to use indigenously designed and manufactured supersonic aircraft, alongside the USA’s Thunderbirds (F-16) and Blue Angels (F/A-18), Russia’s Swifts (MiG-29) and Knights (SU-27), and China’s 1st Aerobatic Team (J-10s). Defense News.

March 15/09: UAE post-mortem. The Korea Times cites an upcoming $500 million competition in Singapore between the Aermacchi M346 and KAI’s T-50, while delving into some of the reasons behind the recent UAE loss:

“The government’s role is much bigger than it appears in this kind of competition,” [the military analyst] said. “And what the Korean government did in the UAE is, to be frank, far from [adequate].” Italy, which had developed close ties with Middle Eastern countries over the years, rolled out marketing promotions there with pledges of large industrial cooperation projects, including construction of an F-1 racing track…. [in contrast] None of the Korean projects have been delivered to Abu Dhabi through a ministerial channel.

When National Assembly Speaker Rep. Kim Hyeong-o visited the UAE in January, he heard from Sheikh Mohammed bin Zayed Al Nahyan, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the UAE Armed Forces, that the preferred bidder will be “decided upon industrial cooperation offered, as well as the trainer jet quality.” He remarked that the country hadn’t heard anything from Seoul for nine months…. To make matters worse, Seoul didn’t even take the opportunity of a last chance from Abu Dhabi, after the Korean delegation failed to make it to February’s International Defense Exhibition & Conference held there, where UAE was awaiting a new offer.”

March 12/09: Price problem? The Korea Times publishes an article that wonders if the T-50’s supersonic speed has created a price handicap:

“Although the UAE acknowledged the T-50 has remarkably high quality, the country apparently put more value on cooperative projects in the aerospace industry that the Italian side pledged,’’ the Ministry of Knowledge Economy said in a statement, which also pointed out a disadvantage in price. A T-50 jet’s flyaway cost is set at 20 billion won to 25 billion won ($13.5 – $16.9 million), while the M-346 costs 18 billion won to 20 billion won.” [$12.15 – $13.5 million]

DID’s take? Advanced jet training does focus on in-air operation, take-off and landing, and blind flying, with secondary weapons training opportunities. Within those constraints, the price of supersonic flight may not be seen as worthwhile. What the capability does, is give the T-50 family a full secondary fighter role that goes beyond the traditional “secondary light ground attack” role for trainers. The ultimate question for the market to answer is how much it values that capability, in an era of shrinking defense budgets that create stronger demands for multi-role platforms, as well as closer attention to costs.

Feb 25/09: UAE setback. At IDEX 2009, the UAE announces that it has begun negotiations for 48 M-346 aircraft from Finmeccanica’s Aermacchi. If the EUR 1 billion deal is finalized, the T/A-50 will have lost this export competition.

Feb 24/09: Iraq. Iraq officially requests T-50 jets, even as Iraq and the ROK sign economic agreements to develop oil fields near Basra, and open Iraqi public infrastructure contracts to South Korean firms.

Feb 11/09: Elisra ECM for FA-50. Flight International reports that Israel’s Elisra will supply the F/A-50’s electronic warfare and self-protection equipment, under an initial contract worth $7 million for the initial 4 prototypes. The equipment will be supplied over the next 2 years, and “Elisra sources indicate that the selected EW system will include radar warning receivers and chaff and flare dispensers.”

This contract involves the adaptation of proven systems, rather than a new design. The joint Elbit systems (70%)/ IAI (30%) venture Elisra already makes the self-protection systems that equip many of the IAF’s F-16s.

Jan 15/09: Iraq. South Korea’s Yonhap news agency and the World Tribune both file reports concerning Iraqi Defense Minister Abdul-Qader al-Obeidi’s ongoing visit to South Korea, which included inspection and a test flight of the T-50. South Korea sent a 3,600-strong contingent to the northern Iraqi city of Irbil in September 2004 as part of the U.S.-led forces, and a total of 18,000 South Korean troops served in rotation around northern Iraq until 2008.

DJ Elliott of the Long War Journal says that the T/A-50 was suggested in fall 2007 to the Iraqi Ministry of Defense by MNSTC-I’s Coalition Air Force Transition Team. Iraq’s pending trainer aircraft purchase appears to be Hawker Beechcraft’s T-6 Texan II, but a jet trainer is required as an interim step between the T-6 and more advanced planes like the F-16s Iraq is requesting. If Iraq begins with T/A-50s, however, they would also become the new IqAF’s first jet fighters, and give Iraq qualitative parity with many of the fighters currently flown by its semi-hostile neighbors Syria and Iran.

Jan 12/09: M61. General Dynamics Armament and Technical Products announces a contract by Korea Aerospace Industries (KAI) for up to 82 of its 3-barreled M61 20mm cannons that will equip the T/A-50 and F/A-50 variants. Price was not disclosed, but deliveries will begin in October 2010.

Manufacturing will be performed at General Dynamics’ Saco, ME, facility, and the program will be managed by General Dynamics’ Burlington, VT facility. S&T Dynamics, LTD of South Korea is the designated Korean Industry Partner (KIP) for the program, and they will produce the ammunition containers under a subcontract arrangement with General Dynamics.

Jan 8/09: The Korea Times reports that Vice Defense Minister Kim Jong-cheon will visit Poland later from Jan 19-23, and that his agenda includes a push for the T-50 trainer. The jets may have very stiff competition, however, as Finland is re-selling its used BAE Hawk trainers.

The report also confirms that competitions are still active in Singapore (12-16 jets, up to $500 million) and the UAE (35-40, $1+ billion, subsequently lost to M346).

Dec 30/08: FA-50 development. South Korea’s Defense Acquisition Program Administration (DAPA) signs a WON 400 billion (about $317 million) contract with Korea Aerospace Industries (KAI) to develop 4 prototypes of the F/A-50 light attack jet by 2012.

Full production of about 60 aircraft is scheduled to begin in 2013, at which point the F/A-50s will begin replacing 1960s era A-37 dragonfly attack jets, F-5E/F Tiger II light fighters, and F-4 Phantom II fighters as the ROKAF’s low-end fighters. The Korean buy could extend to 150 aircraft, and its capabilities and price point make exports likely.

That potential was one of the reasons the F/A-50 project has been delayed. The F/A-50 is a joint KAI/ Lockheed martin project, and the agreement includes a number of provisions related to American weapons export policies, and to corporate interests at Lockheed Martin. One stipulation was that Lockheed would not transfer aircraft source code to other nations. Another was that the T-50’s capabilities could not exceed Korea’s F-16s. A 3rd provision banned South Korea from integrating T-50 variants with non-U.S. technology that the United States doesn’t have.

Korea originally wanted to equip the F/A-50 with the lightweight Vixen-500E AESA radar developed by U.K. firm Selex Sensors and Airborne Systems, but that would have violated all 3 of the above provisions. Lockheed Martin pushed for its AN/APG-67v4 radar, which equips the T/A-50 LIFT. Instead, the Koreans chose the proven EL/M-2032 mechanically scanned radar from Israel’s IAI Elta Systems. That radar serves on some Israeli F-16s and also equips a range of other aircraft around the world that include F-16s, F-4 Phantoms, F-5 Tigers, MiG-21s, Kfirs and other Mirage variants, India’s Sea Harriers, and India’s forthcoming Tejas lightweight fighter. Korea Times.

Dec 10/08: After more than 40 years of service, Israel is finally looking to replace its versatile A-4 Skyhawk fleet. KAI’s T-50 family is reportedly one of the 4 contenders. Read “Israel’s Skyhawk Scandal Leads to End of an Era”.

Aug 28/08: An upgraded F/A-50 lightweight fighter counterpart would be a logical replacement for South Korea’s vintage F-5E/F and F-4 fighter fleet, and may also prove attractive as a global export. Flight International reports that the design is almost complete, but program approval for additional South Korean F/A-50s is being held up by 2 key issues.

One is the desire for an AESA radar, which would sharply improve the little fighter’s capabilities while lowering maintenance costs. Both Northrop Grumman (SABR) and Raytheon (RACR) have designed new AESA radars for F-16 refits, and the nature of AESA radars allows them to be resized very flexibly. The bad news is that negotiations with the US government haven’t been able to secure US authorization for AESA radar exports to South Korea. This forces the Koreans to go ahead with a more conventional but limited radar like the AN/APG-67v4, or put the F/A-50 on hold until AESA approval is granted. If it would be granted to a project that’s likely to compete with made-in-USA F-16s on the global export market.

The other issue is Lockheed Martin’s participation. Lockheed helped develop the T-50, and has the fighter development and advanced weapon integration experience that KAI lacks. On the other hand, its involvement raises costs. KAI is reportedly pushing for this partnership, but the government must conclude that the benefits would be worth those extra costs. Likely arguments to that end include lower project/financial risk, improved export prospects, and greater likelihood of American technology export approvals.

Nov 1/07: UAE. Reports claim that Aermacchi’s M-346 and KAI’s T/A-50 are the finalists in the UAE competition, with Britain’s Hawk LIFT eliminated by BAE’s own admission. Flight International report. A Korea Times report pegs the UAE’s purchase total at 35-40, rather than 60. Time will tell.

They also add a market prediction from KAI officials that expect T-50 variants will secure about 30% of the 3,300 aircraft global trainer market within 25 years – about 1,100 aircraft.

Oct 26/07: KOIS reports that Korea’s commerce and industry minister Kim Young-ju is headed to the United Arab Emirates (UAE), where the T-50 is competing against the BAE Hawk Mk128 LIFT and Aermacchi’s M-346 for an estimated 60-plane, $1+ billion order. The UAE is expected to choose its next generation trainer jet by early November 2007. See “Korea’s commerce, industry minister pitches T-50 jet to UAE.”

Oct 15/07: On the eve of the Seoul 2007 Air Show, KOIS reports that the T-50 is poised to pick up orders in the United Arab Emirates (60 jets), Greece (30), and Singapore (40). “Korea is expected to sign the deals with the three nations this month or next month,” said Yoon Cha-young, executive director of the Korea Aerospace Industries Association.

Dec 13/06: 2nd ROKAF order. The Government of South Korea has signed a contract with Korea Aerospace Industries (KAI) for approximately 50 additional T-50 and TA-50 Golden Eagle advanced jet trainers. The new aircraft will be used for advanced jet training and lead-in fighter training. All the aircraft will be delivered from KAI’s production facility in Sacheon, South Korea. Lockheed Martin release.

Nov 16/06: Lockheed MoU. Korea Aerospace Industries (KAI) and Lockheed Martin sign a memorandum of understanding today to expand their strategic relationship. Ralph Heath, president of Lockheed Martin Aeronautics, in the Lockheed Martin release:

“First, the memorandum is a recommitment to continue our efforts in marketing the T-50 Golden Eagle to international customers. Additionally, we will seek ways to collaborate on future opportunities in Korea, the United States and the international marketplace. We value the important, long-standing relationship we have with KAI.”

“First, the memorandum is a recommitment to continue our efforts in marketing the T-50 Golden Eagle to international customers” said Ralph Heath, president of Lockheed Martin Aeronautics. “Additionally, we will seek ways to collaborate on future opportunities in Korea, the United States and the international marketplace. We value the important, long-standing relationship we have with KAI.”

Hae Joo Chung, KAI president:

“This new agreement means that our two companies will look to cooperate in the areas of aircraft modification and upgrades, as well as the future fighter requirements for the Korean government. The new business sector of Performance Based Logistics Support provides an important opportunity for cooperation with Lockheed Martin in Korea and with international customers.”

July 17/06: Lockheed Martin release: “Last month program officials announced the opening of a new marketing office in Abu Dhabi, United Arab Emirates. This facility gives KAI greater proximity to potential customers in the Middle East and Europe and allows the Korean-based company an opportunity to grow its business-base.”

Jan 4/06: 1st delivery. Korea Aerospace Industries (KAI) delivers its first 2 production T-50 advanced jet trainer aircraft to the Republic of Korea Air Force (ROKAF). Designated KAI-1 and KAI-2, these aircraft are the first deliveries to a customer since the award of the production contract just 24 months ago. In addition to these 2 aircraft, KAI will deliver another 8 aircraft to the ROKAF in 2006, and 1 per month afterward. Lockheed Martin release.

Feb 11/05: The supersonic T-50 Golden Eagle advanced jet trainer has attained several significant technical milestones, including reaching maximum load factors (8g), maximum operating speed (Mach 1.3, design limit Mach 1.5), beginning stores separation testing (fuel tank jettison), and completing its second lifetime (lifetime = 8,334 flight hours) of structural durability testing. Lockheed Martin release.

Oct 26/04 – Jan 6/05: The T-50 Golden Eagle advanced jet trainer successfully completes aerial gunfire testing. A total of 10 test flights were conducted under a variety of flight conditions, including 3 supersonic flights. Testing included operation of the gun and ammo handling system, plus measurement of vibration levels and adequacy of the gun bay gas purging capability.

The tests used the 3rd Full Scale Development aircraft, the first in the A-50 lead-in fighter trainer (LIFT) configuration. The gun is a lighter weight, internally mounted 3-barrel version of General Dynamics’ standard 6-barrel M61 used by many fighters. It has a rate of fire of 3,000 rounds per minute, and the ammo system holds 205 rounds of ammunition. The gun will be used for both ground strafing and aerial gunnery training. Lockheed Martin release.

Feb 7/04: As part of the aircraft’s external stores testing, the first flight with external fuel tanks occurs. The 150-U.S. gallon, jettisonable fuel tanks are built by Sargent Fletcher of El Monte, CA. A single tank extends mission duration and range about 15-20%, and the three-tank configuration extends them by about 40%.

These external stores tests aim to verify the T-50 aircraft’s stability and control, flutter and handling qualities when loaded with fuel tanks, weapons, and other stores. Later flights will verify performance, store functionality and interfaces, and store separation. Approximately 280 sorties utilizing all 4 of the T-50 flight test aircraft are planned for external stores testing with external fuel tanks installed, and external stores flight testing will continue until the end of Full-Scale Development. The ROKAF is conducting the flight testing from Sacheon Air Base, South Korea. Lockheed Martin.

March 15/04: Lockheed Martin announces that the Republic of Korea Air Force (ROKAF) has begun engine air start flight testing of the T-50’s F404-GE-102 jet engine. Air start testing involves intentionally shutting down the engine in flight and restarting it, in order to verify the air start envelope and procedures. This effort is expected to include 15 flight tests over a 7-month period.

Nov 3/03: T-50 Flight testing with captive AIM-9 air-to-air missiles is initiated. Source.

April 28/03: The T-50 Golden Eagle completes its 100th test flight, and reaches a speed of Mach 1.2 on the same day.

On April 25th, the airframe durability vehicle completed one lifetime of testing, equivalent to 8,334 flight hours, at the Agency for Defense Development testing laboratory in Taejon, South Korea. Testing continues on a second lifetime, which is expected to be complete in April 2004. Lockheed Martin.

Feb 19/03: Supersonic. The T-50 achieves supersonic flight for the first time. The milestone flight was accomplished on the No. 1 flight-test aircraft during the 60-minute flight from the air base at Sachon, South Korea. The top speed achieved was Mach 1.05 at an altitude of 40,000 feet. Full afterburner on the General Electric F404-GE-102 engine was used to accelerate to the target speed, then minimum afterburner was used to sustain the speed. Approximately one minute was spent in the supersonic regime.

“The aircraft accelerated through the Mach smoothly and quickly,” said Major Choong Hwan Lee, Republic of Korea Air Force test pilot for the flight. “I observed no adverse flight or handling characteristics. I was able to hold the target speed of Mach 1.05 with plenty of excess power available, so I have no doubt this aircraft will be able to achieve its maximum design Mach of Mach 1.5.” Lockheed Martin release.

Nov 25/02: The T-50 Golden Eagle advanced supersonic trainer reaches its stated operational ceiling of 40,000 feet during a test flight. All systems operate normally.

The actual maximum service ceiling for the T-50 is estimated to be 48,500 feet, the altitude where rate of climb is limited to 100 feet per minute at maximum power (full afterburner). Lockheed Martin.

Nov 8/02: The 2nd T-50 Golden Eagle advanced jet trainer successfully completes its47-minute flight from KAI’s facility at Sachon, South Korea. Lockheed Martin.
