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]

LAS in, LAS out: Counter-Insurgency Planes for the USA and its Allies

Winner

The USA needs a plane that can provide effective precision close air support and JTAC training, and costs about $1,000 per flight hour to operate – instead of the $15,000+ they’re paying now to use advanced jet fighters at 10% of their capabilities. Countries on the front lines of the war’s battles needed a plane that small or new air forces can field within a reasonable time, and use effectively. If these 2 needs are filled by the same aircraft, everything becomes easier for US allies and commanders. One would think that this would have been obvious around October 2001, but it took until 2008 for this understanding to even gain momentum within the Pentagon. A series of intra-service, political, and legal fights have ensured that these capabilities won’t arrive before 2015 at the earliest, and won’t arrive for the USAF at all.

The USA has now issued 2 contracts related to this need. The first was killed by a lawsuit that the USAF didn’t think they could defend successfully. Now, in February 2013, they have a contract that they hope will stick. The 3 big questions are simple. Will the past be prologue for the new award? Will there be an Afghan government to begin taking delivery of their 20 planes much beyond 2014? And will another allied government soon need to use this umbrella contract for its own war?

A Higher-Tech Hog: USAF A-10C Upgrades and Refurbishments

A-10A over Germany

The Precision Engagement modification is the largest single upgrade effort ever undertaken for the USA’s unique A-10 “Warthog” close air support aircraft fleet. While existing A/OA-10 aircraft continue to outperform technology-packed rivals on the battlefield, this set of upgrades is expected to make them more flexible, and help keep the aircraft current until the fleet’s planned phase-out in 2028. When complete, A-10C PE will give USAF A-10s precision strike capability sooner than planned, combining multiple upgrades into 1 time and money-saving program, rather than executing them as standalone projects. Indeed, the USAF accelerated the PE program by 9 months as a result of its experiences in Operation Iraqi Freedom.

This is DID’s FOCUS Article for the PE program, and for other modifications to the A-10 fleet. It covers the A-10′s battlefield performance and advantages, the elements of the PE program, other planned modifications, related refurbishment efforts to keep the fleet in the air, and the contracts that have been issued each step of the way.

Pilum High: The Javelin Anti-Armor Missile

Javelin, firing

The FGM-148 Javelin missile system aimed to solve 2 key problems experienced by American forces. One was a series of disastrous experiences in Vietnam, trying to use 66mm M72 LAW rockets against old Soviet tanks. A number of replacement options like the Mk 153 SMAW and the AT4/M136 spun out of that effort in the 1980s, but it wasn’t until electronics had miniaturized for several more cycles that it became possible to solve the next big problem: the need for soldiers to remain exposed to enemy fire while guiding anti-tank missiles to their targets.

Javelin solves both of those problems at once, offering a heavy fire-and-forget missile that will reliably destroy any enemy armored vehicle, and many fortifications as well. While armored threats are less pressing these days, the need to destroy fortified outposts and rooms in buildings remains. Indeed, one of the lessons from both sides of the 2006 war in Lebanon has been the infantry’s use of guided missiles as a form of precision artillery fire. Javelin isn’t an ideal candidate for that latter role, due to its high cost-per-unit; nevertheless, it has often been used this way. Its performance in Iraq has revealed a clear niche on both low and high intensity battlefields, and led to rising popularity with American and international clients.

South Africa’s Sad Military: Why Maintenance Matters

SAAF JAS-39D

In 1999, South Africa became the Saab JAS-39 Gripen‘s 1st export customer, ordering 26 fighters. The country is generally considered to be one of Africa’s stronger economies, and a regional security partner. On the defense front, their arms firms have managed to survive, albeit with some adjustment pains and restructuring. They can still produce weapons that are relevant on the world stage. Unless current trends change, however, outside views of the country’s regional security role may need a rethink.

Opposition Democratic Alliance MP David Maynier recently forced the ANC government to acknowledge that 12 of its 26 delivered JAS-39C/D fighters were in long term storage. In reality, the SAAF’s fighter problem is even worse than that. He sums up the situation this way:

AGM-88E AARGM Missile: No Place To Hide Down There

AARGM Concept

The AGM-88E Advanced Anti-Radiation Guided Missile (AARGM) is a medium range, supersonic, air-launched tactical missile whose primary job is to attack and kill enemy radars. AARGM is a US Navy major acquisition program, with around 1,750 expected orders from the U.S. Navy and Marine Corps. The Italian Air Force is expected to buy up to 250 of these successors to the AGM-88 High-Speed Anti-Radiation Missile, and Germany may also join.

So, why is AARGM a big deal? Perhaps the story of how a Serbian unit using an antiquated SA-3 battery managed to survive the 1999 NATO air campaign – and shoot down an F-117 Nighthawk stealth plane – will help put things into perspective. DID recounts those events, explains the new weapon, and offers updates on contracts and key milestones.

JHMCS: Fighter Pilots’ “Look & Shoot” Helmets Changing Aerial Warfare

(click to view larger)

In the 1970s, fighter aircraft began to appear with Head-Up Displays (HUD) that projected key information, targeting crosshairs etc. onto a seemingly clear piece of glass. HUDs allowed pilots to keep their eyes in the sky, instead of looking down at their instruments. In the 1990s, another innovation appeared: helmet-mounted displays (HMDs) put the HUD inside the pilot’s helmet, providing this information even when the pilot wasn’t looking straight ahead. The Israelis were already pioneering a system called DASH (Display And Sight Helmet) when a set of former East German MiG-29s, equipped with Soviet HMDs, slaughtered USAF F-16s in NATO exercises. Suddenly, helmet-mounted displays became must-haves for modern fighters – and a key partnership positioned Elbit to take DASH to the next level.

This DID Spotlight article offers insights into the rocky past, successful present, and competitive future of a program that has experienced its share of snags and controversy – but went on to become the #1 helmet-mounted sight in the world. It also details the game-changing effects of Joint Helmet Mounted Cueing Systems on air combat, its production sets and known customers, and all contracts since full-rate production began.

India Moves to Boost Anti-Tank Capabilities

Indian T-90S

India’s armed forces have been complaining of a severe shortage of tank ammunition, and the fleet’s new T-90 tanks have had their share of problems. Over the last couple of weeks, India’s Cabinet Committee on Security (CCS) has moved to patch these gaps, by approving budgets for a pair of purchases. One is a gun-launched missile that can make the T-90 fleet more effective, while supplementing existing tank ammunition. The other is a follow-on order for an anti-tank missile that can be used by the infantry or mounted on vehicles.

Taken together, India hopes to add some punch to its mechanized divisions in particular.

Gulf Chokepoint: Seafox Saves the Day?

Seafox Mk.II

Rising tensions in the Persian Gulf, coupling increasingly bellicose actions by Iran with pointed American warnings, have left international navies thinking hard about how to keep the Strait of Hormuz open for oil traffic. Naval mines, which can be laid by submarines or boats, remain one of the most difficult and inconvenient threats to counter. That was true during the last set of armed clashes between the USA and Iran in the 1980s. It remains true, and the USA has weakened its position by retiring its modern Osprey Class minehunter ships. Some are available for reactivation in an emergency, but their place was supposed to be taken by the MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system.

The USA is looking to bolster its defenses in the Straits, but AMCM isn’t quite ready yet. That leaves them looking elsewhere for urgent operational buys. While countries like China counter mines using unmanned ships, the US Navy is turning toward a widely-bought German UUV…

Thailand’s Insurgency: The Blimp and I

Aria’s airship

In early 2009, Aria International, Inc. announced a contract from the Royal Thai Army to provide in-country surveillance and communications solutions and services, for an aggregate purchase price of $9.7 million. The RTA surveillance system consists of a manned airship with military-grade imaging and communications systems, an armored Command and Control vehicle, and upgrades to existing communications and facilities to receive real-time surveillance data.

Thailand has the questionable distinction of being saddled with the bloodiest Islamist insurgency most people have never heard of. The American export system that has hindered their order is well known around the world… but it looks like everything has been ironed out. Unfortunately, Thailand hasn’t been able to get much value out of its new asset.
