AH-64E Apache Block III: Evolving Battlefield Roles

The AH-64 Apache will remain the US Army’s primary armed helicopter for several more decades, thanks to the collapse of the RAH-66 Comanche program, and the retirement sans replacement of the US Army’s Armed Reconnaissance Helicopter (ARH). Apaches also serve with a number of American allies, some of whom have already expressed interest in upgrading or expanding their fleets.

The AH-64E Guardian Block III (AB3) is the helicopter’s next big step forward. It incorporates 26 key new-technology insertions that cover flight performance, maintenance costs, sensors & electronics, and even the ability to control UAVs as part of manned-unmanned teaming (MUT). In July 2006, Boeing and U.S. Army officials signed the initial development contract for Block III upgrades to the current and future Apache fleet, via a virtual signing ceremony. By November 2011, the 1st production helicopter had been delivered. So… how many helicopters will be modified under the AH-64 Block III program, what do these modifications include, how is the program structured, and what has been happening since that 2006 award? The short answer is: a lot, including export interest and sales.

KF-X Fighter: Korea’s Future Homegrown Jet

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…

KC-46A Pegasus Aerial Tanker Completes Firsts

DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.

KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.

In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.

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

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]

AIM-9X Block II & Beyond: The New Sidewinder Missiles

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 T-50 Family of Trainers/Fighters

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.

Most recently, Thailand is increasing its defense budget and the speed of its procurement process to, among other things, procure a replacement for its aging L-39. The T-50 is one of three candidates.

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.

South Korea Launches KF-16 Fighter Upgrades Upended

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 effort 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.

Turkey & South Korea’s Altay Tank Project

Turkey’s tank fleet is currently made up of American M-48s and M-60s, some of which have been modernized with Israeli cooperation into M-60 Sabra tanks, plus a large contingent of German Leopard 1s and Leopard 2s. That is hardy surprising. America and Germany are Turkey’s 2 most important geopolitical relationships, and this is reflected in Turkey’s choice of defense industry partners. The country’s industrial offset requirements ensure that these manufacturers have a long history of local partnerships to draw upon.

In recent years, however, a pair of new players have begun to make an impact on the Turkish defense scene. One was Israel, whose firms specialized in sub-systems, upgrades, and UAVs. The other is the Republic of [South] Korea, who has made inroads in the Turkish market with turboprop training aircraft, mobile howitzers… and now, main battle tanks.

Sons of Sa’ar? Israel’s Next Generation Frigates

The 1,227t/ 1,350 ton Sa’ar 5 Eilat Class corvettes were built by Northrop Grumman in the 1990s for about $260 million each. It’s a decent performer in a number of roles, from air defense to anti-submarine work, to coastal patrol and special forces support. In 2006, the Israelis went looking for a next-generation vessel with better high-end capabilities. Six years later, Israel had nothing to show for its search. In the meantime, massive natural gas deposits have been discovered within Israel’s coastal waters, adding considerable urgency to their search.

The USA is Israel’s logical supplier, but given Israel’s size and cost requirements, the only American option was the Littoral Combat Ship. Israel pursued that option for several years, conducting studies and trying to get a better sense of feasibility and costs. Their approach would have been very different from the American Freedom Class LCS, removing the swappable “mission modules” and replacing them with a fixed and fully capable set of air defense, anti-ship, and anti-submarine weapons. In the end, however, the project was deemed to be unaffordable. Instead, Israel began negotiating with Germany, and reports now include discussions involving both South Korea, and a local shipyard.

Pining for Control: South Korea’s KAMD National Ballistic Missile Defense System & M-SAM Surface to Air Missile

South Korea continues to modernize its forces, and take steps toward full sovereign control of its defenses. PAC-2 GEM+ missiles were ordered in 2008 to be operational in 2010 and fully in place by 2012. South Korea doesn’t appear to be aiming as high as Japan, with its license-produced Patriot PAC-3s and long-range naval SM-3 systems, but medium range SM-2 Block IIIA/B missiles fired from ROKN KDX-III destroyers do offer another limited option for the ROK’s coastal cities.

As countries like the UAE have been quick to recognize, turning a series of point defenses into a cohesive system that can respond in time requires long-range detection, and strong regional command-and-control systems. Now, a key contract has been signed, as South Korea prepares to field its Air and Missile Defense Cell (AMD-Cell) radars and command system.
