Raytheon’s AIM-9X Block II would have made Top Gun a very short movie. It’s the USA’s most advanced short range air-air missile, capable of using its datalink, thrust vectoring maneuverability, and advanced imaging infrared seeker to hit targets behind the launching fighter. Unlike previous AIM-9 models, the AIM-9X can even be used against targets on the ground.

These changes will help keep it competitive against foreign missiles like MBDA UK’s AIM-132 ASRAAM, RAFAEL of Israel’s Python 5, the multinational German-led IRIS-T, and Russia’s R73/ AA-11 Archer. So far, only American fighter types can use AIM-9X missiles, but that hasn’t stopped a slew of export requests and sales, especially in the Middle East…

Korea’s F-X Multi-Role Fighter Buys: Phases 2 & 3

F-15K Poster: apropos?

The ROKAF (Republic of Korea Air Force) originally planned to buy 120 advanced, high-end fighters as its next-generation platform, in order to replace its existing fleet of F-4 Phantom IIs and other aircraft. So far, it has bought 60 fighters in 2 phases. Back in 2002, the Republic of Korea Air Force (ROKAF) selected the F-15K advanced derivative of the F-15E Strike Eagle for its Next Generation Fighter Program, and bought 40. In 2008, a 2nd contract was signed for 20 more F-15ks, with slight modifications.

Now the 3rd phase looms, and the question is whether it will be a variant of their existing fleet, or something new. While the DAPA procurement agency dreamed of developing their own “5th generation” aircraft for Phase 3, reality eventually had its say. Now, foreign manufacturers are offering the ROKAF a number of options.

KF-X Fighter: Pushing Paper, or Peer Program?

KODEF ’11 slide

South Korea has been thinking seriously about designing its own fighter jet since 2008. The ROK defense sector has made impressive progress, and has become a notable exporter of aerospace, land, and naval equipment. The idea of a plane that helps advance their aerospace industry, while making it easy to add new Korean-designed weapons, is very appealing. On the flip side, a new jet fighter is a massive endeavor at the best of times, and wildly unrealistic technical expectations didn’t help the project. KF-X has progressed in fits and starts, and became a multinational program when Indonesia joined in June 2010. As of March 2013, however, South Korea has decided to put the KF-X program on hold for 18 months, while the government and Parliament decide whether it’s worth continuing.

Indonesia has reportedly contributed IDR 1.6 trillion since they joined in July 2010 – but that’s just $165 million of the DAPA’s estimated WON 6 billion (about $5.5 billion) development cost, and there’s good reason to believe that even this development budget is too low. This article discusses the KFX/IFX fighter’s proposed designs and features, and chronicles the project’s progress and setbacks since 2008.

Hydra, Awakened: Guided Air-Ground Rockets

(click to view larger)

Sen. Leahy’s [D-VT] worked in the mid-2000s to keep the Hydra 70mm rocket family alive through special appropriations, just in time for the Hydras’ potential on the battlefield to rise again. The key was the addition of low-cost precision guidance, which would expand the number of precision weapons carried by helicopters, aircraft, and even UAVs.

Over the last few years, the US Army’s 2nd attempt at an APKWS 70mm guided rocket had a near-death experience, before righting the program with Navy funding. Meanwhile, private development efforts from Lockheed Martin, Thales TDA, and a raft of international partnerships involving major defense firms and partners in Korea, the UAE, Canada/Norway, and Israel are introducing new competitors into the precision-guided rocket space. This DID FOCUS article covers the most prominent competitors within the guided rocket trend. Their products will sit between full anti-armor missiles like Hellfire, TOW, and Brimstone, and an emerging class of ultra-small precision attack weapons like Northrop Grumman’s Viper Strike, Raytheon’s Griffin, etc.

Korea’s T-50 Family Spreads Its Wings

T-50 Golden Eagle

South Korea’s T-50 Golden Eagle family offers the global marketplace a set of high-end supersonic trainer and lightweight fighter aircraft. They’re hitting the international market at a good time: 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 ROK’s defense industry is advancing on all fronts these days. Its shipbuilding industry, one of the world’s busiest, is beginning to turn out its own LHDs, and even high-end KDX-III AEGIS destroyers. On the armored vehicle front, Korea’s 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. Now its aerospace industry is in flight abroad with the KT-1 turboprop basic trainer, complemented by the T-50 jet trainer, TA-50 LIFT advanced trainer & attack variant, and FA-50 lightweight fighter.

The TA-50 and FA-50 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. The key question for the platform is whether it can find corresponding export sales.

JDAM: A GPS-INS Add-on Adds Accuracy to Airstrikes

B-2 drops JDAM

Precision bombing has been a significant military goal since the invention of the Norden bomb sight in the 1920s, but its application remained elusive. Over 30 years later, in Vietnam, the destruction of a single target could require 300 bombs, which meant sending an appropriate number of fighters or bombers into harm’s way to deliver them. Even the 1991 Desert Storm war with Iraq featured unguided munitions for the most part. The USAF some laser and TV-guided weapons like Paveway bombs and Maverick missiles, but they were very expensive, and only effective in good weather. If precision bombing was finally to become a reality throughout the Air Force, a new approach would be needed. The Joint Direct Attack Munition (JDAM) became that alternative, an engine of military transformation that was also a model of procurement transformation.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This DID FOCUS Article looks at the transformational history of the JDAM GPS-guided bomb program, the ongoing efforts to bring its capabilities up to and beyond the level of dual-mode guidance kits like Israel’s Spice and Raytheon’s Enhanced Paveway, and the contracts issued under the JDAM program since its inception.[updated]

South Korea Looking to Upgrade its KF-16 Fighters

ROKAF KF-16

In July 2009, The Korea Times reported that ROKAF was looking to upgrade its F-16C/D fleet’s radar and armament, as part of the 2010-2014 arms acquisition and management package submitted to President Lee Myung-bak for approval.

Under the Peace Bridge II and II deals, The ROKAF bought 140 “KF-16″ Block 52 fighters, which were assembled in Korea between 1994-2004 under a $5.5 billion licensing agreement. Key upgrades to this fleet will include new radars to replace the existing APG-68v5/v7 systems, modern avionics and computers, and upgrades of the planes’ cabling and databuses to MIL-STD-1760. The centerpiece AESA radar competition has a winner now, and South Korea has picked its contractor for the overall upgrade program. Now the challenge is turning that into binding contracts, and beginning the upgrade process. Other countries within the region and beyond are interested in similar high-value F-16 upgrade programs, so the ROk’s experiences will be watched carefully.

Submarines for Indonesia

KRI Cakra

Indonesia sites astride one of the world’s most critical submarine chokepoints. A large share of global trade must pass through the critical Straits of Malacca, and the shallow littoral waters around the Indonesian archipelago. That makes for excellent submarine hunting grounds, but Indonesia has only 2 “Cakra Class”/ U209 submarines in its own fleet, relying instead on frigates, corvettes, and fast attack craft.

South Korea’s Daewoo, which has experience building U209s for South Korea, has been contracted for Cakra Class submarine upgrades. Even so, submarine pressure hulls have inflexible limits on their safe lifetime, due to repeated hydraulic squeezing from ascending and descending. The Indonesians have expressed serious interest in buying 3-6 replacement submarines since 2007, with French, German, Russian, South Korean, and even Turkish shipyards in the rumored mix. Other priorities shoved the sub purchase aside, but a growing economy and military interest finally revived it. South Korea was the beneficiary, but further orders may be in store.

Korea’s KDX-III AEGIS Destroyers

ROKS King Sejong the Great,
RIMPAC 2010

KDX (Korean Destroyer eXperimental) is the Republic of Korea’s big surface combatant shipbuilding program. This 3-phased program involves 3 individual classes of ships. The 3 KDX-I Gwanggaeto the Great Class ships are called destroyers, but at 3,800 tons, their size and armament more properly rank them as small frigates. The last ship of class was commissioned in 2000. The next 6 KDX-II Chungmugong Yi Sun-sin Class ships are indeed destroyers at 6,085 tons full load, with a hull design licensed from Germany’s IABG, and more advanced systems that include SM-2 air defense missiles. They were commissioned between 2003-2008.

With that experience under their belts, Korea entered the 3rd phase of the program. Their KDX-III King Sejong the Great Class destroyers weigh in at 8,500 tons standard displacement and 11,000 tons full load. That’s heavier than the USA’s CG-47 Ticonderoga Class cruisers, making them the largest ships in the world to carry Lockheed Martin’s AEGIS combat system. They’ll form the high end of South Korea’s Navy, while offering a premium showcase for some of the new weapons and electronic systems developed by South Korea’s defense sector.

RAM (Rolling Airframe Missile) Systems: Contracts & Events

Mk-44 firing RAM

The Rolling Airframe Missile (RAM) MK-31 guided missile weapon system is co-developed and co-produced under a NATO cooperative program between the United States and German governments to provide a small, all-weather, low-cost self-defense system against aircraft and cruise missiles. The RIM-116 was later called RAM (Rolling Airframe Missile), because it spins during flight. To save costs, Designation Systems notes that the RAM was designed to use several existing components, including the rocket motor of the MIM-72 Chaparral, the warhead of the AIM-9 Sidewinder, and the Infrared seeker of the FIM-92 Stinger. Cueing is provided by the ship’s radar, or by its ESM signal tracing suite.

RAM is currently installed, or planned for installation, on 78 U.S. Navy and 30 German Navy ships, including American LSD, LHD, LPD and CVN ship types. This number will grow as vessels of the LPD-17 San Antonio Class and Littoral Combat Ships enter the US Navy, and the LCS will sport an upgraded SeaRAM system that will include its own integrated radar and IR sensors. Abroad, the South Korean Navy has adopted RAM for its KDX-II and KDX-III destroyers, and its LPX Dokdo Class amphibious assault ships; other navies using or buying RAM include Egypt, Greece, Japan, South Korea, Turkey, and the UAE/Dubai.
