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]

The F-22 Raptor: Program & Events

The 5th-generation F-22A Raptor fighter program has been the subject of fierce controversy, with advocates and detractors aplenty. On the one hand, the aircraft offers full stealth, revolutionary radar and sensor capabilities, dual air-air and air-ground SEAD (Suppression of Enemy Air Defenses) excellence, the ability to cruise above Mach 1 without afterburners, thrust-vectoring super-maneuverability… and a ridiculously lopsided kill record in exercises against the best American fighters. On the other hand, critics charged that it was too expensive, too limited, and cripples the USAF’s overall force structure.

Meanwhile, close American allies like Australia, Japan and Israel, and other allies like Korea, were pressing the USA to abandon its “no export” policy. Most already fly F-15s, but several were interested in an export version of the F-22 in order to help them deal with advanced – and advancing – Russian-designed aircraft, air-to-air missiles, and surface-to-air missile systems. That would have broadened the F-22 fleet in several important ways, but the US political system would not or could not respond.

This DID FOCUS Article tracks continuing maintenance and fleet upgrade programs, contracts, and timely news. A separate public-access feature offers a profile of the USAF’s most advanced fighter, and covers both sides of the F-22 Raptor program’s controversies.

Taiwan’s Force Modernization: The American Side

Despite China’s ominous military buildup across the strait, key weapons sales of P-3 maritime patrol aircraft, Patriot PAC-3 missiles, and diesel-electric submarines to Taiwan had been sabotaged by Taiwanese politics for years – in some cases, since 1997. The KMT party’s flip-flops and determined stalling tactics eventually created a crisis in US-Taiwan relations, which finally soured to the point that the USA refused a Taiwanese request for F-16C/D aircraft.

That seems to have brought things to a head. Most of the budget and political issues were eventually sorted out, and after a long delay, some major elements of Taiwan’s requested modernization program appear to be moving forward: P-3 maritime patrol aircraft, UH-60M helicopters, Patriot missile upgrades; and requests for AH-64D attack helicopters, E-2 Hawkeye AWACS planes, minehunting ships, and missiles for defense against aircraft, ships, and tanks. These are must-have capabilities when facing a Chinese government that has vowed to take the country by force, and which is building an extensive submarine fleet, a large array of ballistic missiles, an upgraded fighter fleet, and a number of amphibious-capable divisions. Chinese pressure continues to stall some of Taiwan’s most important upgrades, including diesel-electric submarines, and new American fighter jets. Meanwhile, other purchases from abroad continue.

The MQ-4C Triton: Poseidon’s Unmanned Herald

The world’s P-3 Orion fleets have served for a long time, and many are reaching the end of their lifespans. In the USA, and possibly beyond, the new P-8 Poseidon Multi-mission Maritime Aircraft will take up the P-3’s role. While the P-8’s base 737-based airframe offers strong service & maintenance arguments in its favor, the airframe is expensive enough that the P-3s cannot be replaced on a 1:1 basis.

In order to extend the P-8 fleet’s reach, and provide additional capabilities, the Poseidon was expected to work with at least one companion UAV platform. This DID FOCUS Article explains the winning BAMS (Broad Area Maritime Surveillance) concept, the program’s key requirements, and its international angle. We’ll also cover ongoing contracts and key events related to the program, which chose Northrop Grumman’s navalized MQ-4C Triton Global Hawk variant.

Eurofighter’s Future: Tranche 3, and Beyond

The multi-national Eurofighter Typhoon has been described as the aerodynamic apotheosis of lessons learned from the twin engine “teen series” fighters that began with the F-14 and F-15, continued with the emergence of the F/A-18 Hornet, and extended through to the most recent F/A-18 Super Hornet variants. Aerodynamically, it’s a half generation ahead of all of these examples, and planned evolutions will place the Eurofighter near or beyond parity in electronic systems and weapons.

The 1998 production agreement among its 4 member countries involved 620 aircraft, built with progressively improved capabilities over 3 contract “tranches”. By the end of Tranche 2, however, welfare state programs and debt burdens had made it difficult to afford the 236 fighters remaining in the 4-nation Eurofighter agreement. A 2009 compromise was found in the EUR 9 billion “Tranche 3A” buy, and the program has renewed its efforts to secure serious export sales. Their success will affect the platform’s production line in the near term, and its modernization plans beyond that.

NH90: Europe’s Medium Helicopter Gets New Order Despite Issues

The NH90 emerged from a requirement that created a NATO helicopter development and procurement agency in 1992 and, at almost the same time, established NH Industries (62.5% EADS Eurocopter, 32.5% AgustaWestland, and 5% Stork Fokker) to build the hardware. The NATO Frigate Helicopter was originally developed to fit between light naval helicopters like AW’s Lynx or Eurocopter’s Panther, and medium-heavy naval helicopters like the European EH101. A quick look at the NFH design showed definite possibilities as a troop transport helicopter, however, and soon the NH90 project had branched into 2 versions, with more to follow.

The nearest equivalent would be Sikorsky’s popular H-60 Seahawk/ Black Hawk family, but the NH90 includes a set of innovative features that give it some distinguishing selling points. Its combination of corrosion-proofing, lower maintenance, greater troop or load capacity, and the flexibility offered by that rear ramp have made the NH90 a popular global competitor.

As many business people discover the hard way, however, success can be almost as dangerous as failure. NH Industries has had great difficulty ramping up production fast enough to meet promised deliveries, which has left several buyers upset. Certification and acceptance have also been slow, with very few NH90s in service over a decade after the first contracts were signed. Booked orders have actually been sliding backward over the last year, and currently stand at around 500 machines, on behalf of 14 nations.

The Fighter Still Remains… The Boxer MRAV APC Family

Wheeled armored vehicles have become much more common, but the Dutch-German Boxer stands out from the crowd. Its English acronym is “Multi Role Armoured Vehicle” (MRAV), but rather than being a family of different vehicles, the Boxer will use a single chassis, with snap-in modules for different purposes from infantry carrier to command, cargo, ambulance, etc.

The base vehicle has a maximum road speed of 100 km/h (60 mp/h) and an operational range of 1,000 km (600 miles). In its troop carrying configuration, it has a crew of 2 and can carry 10 fully equipped troops. The MRAV is fighting for space in a crowded market, but its principal countries are beginning to give it the front-line credibility it needs to succeed.

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…

Israel’s Arrow Theater Missile Defense

In a dawning age of rogue states, ballistic missile defenses are steadily become a widely accepted necessity. Iran is widely believed to be developing nuclear capabilities, and Israeli concerns were heightened after Iranian President Mahmoud Ahmadinejad urged that Israel be “wiped off the map” (the fact that America was also placed in that category went largely uncovered).

Because missile defenses are so important, states like India and Israel have taken steps to ensure that they have the ability to build many of the key pieces. The Arrow project is a collaboration between Boeing and IAI to produce the missile interceptors that accompany the required radars, satellites, command and control systems.

RIM-162 ESSM Missile: Naval Anti-Air in a Quad Pack

The RIM-162 Evolved Sea Sparrow Missile (ESSM) is used to protect ships from attacking missiles and aircraft, and is designed to counter supersonic maneuvering anti-ship missiles. Compared to the RIM-7 Sea Sparrow, ESSM is effectively a new missile with a larger, more powerful rocket motor for increased range, a different aerodynamic layout for improved agility, and the latest missile guidance technology. Testing has even shown the ESSM to be effective against fast surface craft, an option that greatly expands the missile’s utility. As a further bonus, the RIM-162 ESSM has the ability to be “quad-packed” in the Mk 41 vertical launching system, allowing 4 missiles to be carried per launch cell instead of loading one larger SM-2 Standard missile or similar equipment.

This is DID’s FOCUS article for the program, containing details about the RIM-162 Evolved Sea Sparrow missile family, and contracts placed under this program since 1999. The Sea Sparrow was widely used aboard NATO warships, so it isn’t surprising that the ESSM is an international program. The NATO Sea Sparrow Consortium includes Belgium, Canada, Denmark, Germany, Greece, The Netherlands, Norway, Portugal, Spain, Turkey, and the USA – as well as non-NATO Australia. Foreign Military Sales ESSM customers outside this consortium include Japan, Thailand, and the United Arab Emirates.
