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]

“Bird Dog” Light Planes for Afghanistan

“Bird Dogs for the Iraqi Air Force” has covered the growth of Iraq’s primary trainer fleet of Cessna 172 and 208Bs, alongside surveillance and even attack variants of the same aircraft. Now, Afghanistan is beginning the same process, and needs primary training aircraft for new air force candidates. Soon, they may need more.

Active military use of “grasshopper”/ “bird dog” aircraft is merely the re-invention of doctrines that worked very well in World War 2, Korea, and Vietnam. The combination of lower tech, lower prices, and lower crash rates than UAVs will continue to give “bird dog” aircraft a military role as light cargo planes, spotters, and even attack aircraft in countries that are watching their budgets…

MQ-9 Reaper: Unfettered for Export

The MQ-9 Reaper UAV, once called “Predator B,” is somewhat similar to the famous Predator. Until you look at the tail. Or its size. Or its weapons. It’s called “Reaper” for a reason: while it packs the same surveillance gear, it’s much more of a hunter-killer design. Some have called it the first fielded Unmanned Combat Air Vehicle (UCAV).

The Reaper UCAV will play a significant role in the future USAF, even though its capability set makes the MQ-9 considerably more expensive than MQ-1 Predators. Given these high-end capabilities and expenses, one may not have expected the MQ-9 to enjoy better export success than its famous cousin. Nevertheless, that’s what appears to be happening. MQ-9 operators currently include the USA and Britain, who use it in hunter-killer mode, and Italy. Several other countries are expressing interest, and the steady addition of new payloads are expanding the Reaper’s advantage over competitors…

AMRAAM: Deploying & Developing America’s Medium-Range Air-Air Missile

Raytheon’s AIM-120 Advanced, Medium-Range Air to Air Missile (AMRAAM) has become the world market leader for medium range air-to-air missiles, and is also beginning to make inroads within land-based defense systems. It was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag. This DID FOCUS article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors.

One of the key lessons learned from Vietnam was that a fighter would be likely to encounter multiple enemies, and would need to launch and guide several missiles at once in order to ensure its survival. This had not been possible with the AIM-7 Sparrow, a “semi-active radar homing” missile that required a constant radar lock on one target. To make matters worse, enemy fighters were capable of launching missiles of their own. Pilots who weren’t free to maneuver after launch would often be forced to “break lock,” or be killed – sometimes even by a short-range missile fired during the last phases of their enemy’s approach. Since fighters that could carry radar-guided missiles like the AIM-7 tended to be larger and more expensive, and the Soviets were known to have far more fighters overall, this was not a good trade.

Ships Ahoy! The Harpoon Missile Family

The sub-sonic, wave-skimming GM-84 Harpoon is the US Navy’s sole anti-shipping missile, with the minor exception of small helicopter-borne AGM-119B Penguin missiles. The Harpoon has been adapted into several variants, and exported to many navies around the world. At present, the Harpoon family includes AGM-84 air, RGM-84 sea/land, and UGM-84 submarine-launched versions. Variants such as the Joint Standoff Land Attack Missiles and the upgraded AGM-84K SLAM – Expanded Response will also be covered in this DID FOCUS Article. It describes the missiles themselves, and covers global contracts involving this family.

The Harpoon family’s best known competitor is the French/MBDA M38/39/40 Exocet, but recent years have witnessed a growing competitive roster at both the subsonic (Israel’s >Gabriel family, Russia’s SS-N-27 Klub family, Saab’s RBS15, Kongsberg’s stealthy NSM, China’s YJ-82/C-802 used by Hezbollah in Lebanon), and supersonic (Russia’s SS-N-22 Sunburn/Moskit, SS-N-26 Yakhont, and some SS-N-27 Klub variants, India’s SS-N-26 derived PJ-10 BrahMos) tiers.

Pakistan & China’s JF-17 Fighter Program

The FC-1/ JF-17 Thunder is a joint Chinese-Pakistani project that aimed to reduce Pakistan’s dependence on western firms for advanced fighters, by fielding a low-cost multi-role lightweight fighter that can host modern electronics and precision-guided weapons. It isn’t a top-tier competitor, but it represents a clear step up from Pakistan’s Chinese MiG-19/21 derivatives and French Mirage III/V fighters. This positioning addresses a budget-conscious, “good enough” performance market segment that the West once dominated, but has nearly abandoned in recent decades.

Pakistan has fielded JF-17s in squadron strength, with more on order and a Block II R&D program nearing completion. India’s competing Tejas fighter is overcoming project delays by looking to foreign component sources, but Pakistan and China remain out front with their offering, even though they began their project much later than India did. Pakistan and China have even set up a joint JF-17 marketing agency to promote export sales, which hasn’t paid off as quickly as they had hoped, but it would be unwise to count them out just yet…

Double-Jointed & Popular: The Bv Family of Infantry Support Vehicles

The BvS10 is the successor to the wildly popular Bv206, 11,000 of which have been sold to 40 countries around the world – including the USA (M978). Readers may have seen these vehicles elsewhere, too, as a number of Bv206s have post-military careers at ski resorts, in industries like mining and logging, etc. The new BvS-10 is larger and more heavily armored; it’s in use in Britain, France and the Netherlands as a key armored vehicle for their respective Marines, has been bought by Sweden, and is under evaluation elsewhere. International interest includes imitators: Singapore’s Bronco ATTC is a BVS10 competitor, and Finland and Norway have their own local Bv206 variants.

What makes this unusual-looking vehicle family and design so popular? They aren’t like Humvees or similar wheeled mainstays. They aren’t full armored personnel carriers, either – they’re armored, but Bv family vehicles can’t take the kind of punishment that a Bradley or LAV can absorb. Instead, the secret to their success lies in a remarkable all-terrain capability, and their ability to fill a rare and critical role: air-portable and amphibious infantry enhancement. These success factors are discussed below, along with contracts and key developments related to this vehicle family.

India & Israel’s Barak-8 SAM Development Project(s)

Over a development timeline measured in decades, India’s indigenous “Akash” and “Trishul” programs for surface to air missiles have failed to inspire full confidence. Trishul was eventually canceled entirely. Akash had a a long, difficult development period, but seems to have found customer acceptance and a solid niche in the rugged terrain of the northeast. India still needed longer-range advanced SAMs to equip its navy and army, however, and decided to try to duplicate the success of the partnership model that had fielded the excellent Indo-Russian PJ-10 BrahMos supersonic cruise missile.

In February 2006, therefore, Israel and India signed a joint development agreement to create a new Barak-NG medium shipborne air defense missile, as an evolution of the Barak-1 system in service with both navies. In July 2007 the counterpart MR-SAM project began moving forward, aiming to develop a medium range SAM for use with India’s land forces. Both missiles would now be called Barak-8. In between, “India to Buy Israeli “SPYDER” Mobile Air Defense System” covered India’s move to begin buying mobile, short-range surface-to-air missile (SAM) systems for its army, based on the Python and Derby air-to-air missiles in service with its air force and naval aircraft. These projects offer India a way forward to address its critical air defense weaknesses, and upgrade “protection of vital and strategic ground assets and area air defence.” This DID FOCUS article will cover the Barak-8 and closely related programs in India, Israel, and beyond.

Phalanx CIWS: The Last Defense, On Ship and Ashore

The radar-guided, rapid-firing MK 15 Phalanx Close-In Weapons System (CIWS, pron. “see-whiz”) can fire between 3,000-4,500 20mm cannon rounds per minute, either autonomously or under manual command, as a last-ditch defense against incoming missiles and other targets. Phalanx uses closed-loop spotting with advanced radar and computer technology to locate, identify and direct a stream of armor piercing projectiles toward the target. These capabilities have made the Phalanx CIWS a critical bolt-on sub-system for naval vessels around the world, and led to the C-RAM/Centurion, a land-based system designed to defend against incoming artillery and mortars.

This DID Spotlight article offers updated, in-depth coverage that describes ongoing deployment and research projects within the Phalanx family of weapons, the new land-based system’s new technologies and roles, and international contracts from FY 2005 onward. As of Feb 28/07, more than 895 Phalanx systems had been built and deployed in the navies of 22 nations.

Czech L-159s: Cheap to Good Home

Czechoslovakia originally ordered 72 of Aero Vodochody’s sub-sonic L-159A single-seat light attack jets. Their preceding L-39/59 Albatros trainer and light attack aircraft family became the world’s most popular jet trainers during the Cold War, and the L-159A Advanced Light Combat Aircraft was positioned as a modern derivative, offering full combat capability and compatibility with western weapons. The resulting aircraft filled a useful niche for the Czechs, but its overall success always depended on exports.

Unfortunately, the Soviet Union’s demise lost the Albatros family its global market niche, and killed the military aid subsidies that had helped promote it. Worse, the L-159’s program cost grew from CZK 20-30 billion to over 51 billion Koruna. That left the Czech government in a bind. In response, they kept 24-35 jets for operational use, and have been trying to sell off 36-47 of the L-159As (one aircraft has been lost) since 2002. They also moved to privatize state-owned Aero Vodochody, which took place in November 2006.

A few 2-seat L-159T conversions have been performed with CzAF funding, as a demonstration of their potential to become dual-role trainer/attack aircraft. That has helped Aero tout the planes to Afghanistan, Bolivia, Colombia, Georgia, Indonesia, Iraq, and Nigeria. Their breakthrough, such as it is, came elsewhere.
