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]

Pilum High: The Javelin Anti-Armor Missile

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.

Britain’s Future Frigates: Type 26 Global Combat Ships

In the late 2000s Britain slated to replace its existing fleet of Type 22 Broadsword Class and Type 23 Duke Class frigates with 2 new ship classes under a program known then as “Future Surface Combatant” (FSC). By the 2010 Strategic Defence and Security Review (SDSR), the FSC’s C1 (T26) and C2 (type 27) tentative variants were merged into a single Type 26 Global Combat Ship (GCS) class.

Outside attention often focuses on big-ticket ships like aircraft carriers, submarines, and advanced destroyers – but the frigate is the real backbone of most modern navies.

Lord Nelson loved his HMS Victory and her fellow first-rate ships of the line, but he asked the admiralty for more cruisers because he knew their versatile value as the “eyes of the fleet.” Modern multi-role frigates that can engage threats on the water, under water, and in the air fill that same role today, protecting other navy ships or undertaking independent action away from their task group.

The Type 26 GCS will have to fill that niche – but first, its requirements and design must be defined.

The US Military’s King Air 350ER Aircraft: Quietly Effective

Despite all of the high-tech fighter hours flown in theater, Hawker Beechcraft’s twin-propeller King Air 350 continues to gain traction as an affordable, long-endurance option for light cargo delivery in remote areas – and effective manned battlefield surveillance and attack. Iraq’s Air Force was the first to order them, and an initial 6-plane UC-12W order from the US Marines/Navy followed in July 2008.

Former US Secretary of Defense Robert Gates pushed hard to improve ISR (Intelligence, Surveillance & Reconnaissance) capabilities on the front lines, and one of those planned purchases involved about 30 King Air 350/ C-12 aircraft for the Army. These “MC-12s” have proven to be very useful as a component of the Army’s Task Force ODIN, which has combined the respective advantages of UAVs and manned aircraft to improve aerial surveillance and response over Iraq. ODIN is credited with a number of successes on the ground, and the concept is being exported to Afghanistan. Part of that process involves buying new, updated aircraft, and the US military continues to buy KA350 turboprops for use in different configurations.

A Higher-Tech Hog: USAF A-10C Upgraded, Refurbished, Unloved – But More in Demand

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.

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

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.

The C-27J Spartan Joint Cargo Aircraft

When the WALRUS super-heavy cargo airship was canceled, combat commanders complained that front-line airfields were often too short for the C-130 Hercules that make up the USAF’s tactical transport fleet. Delays in buying a small cargo aircraft to fill that role were making that problem worse. Starved of useful help due to USAF-sponsored delays, and the lack of appropriate aircraft in the USAF, the Army carried on with its aging C-23 Sherpas, and repurposed aircraft like the unprotected C-12 Hurons, in order to ferry troops, supplies, and/or very small vehicles within its theaters of operations.

The Joint Cargo Aircraft (JCA) could have been worth up to $6 billion before all was said and done, and the finalists were a familiar duo. After EADS-CASA’s CN-235 and a shortened version of Lockheed Martin’s C-130J were disqualified for failing to meet requirements, JCA became yet another international competition between EADS-CASA’s C-295M & Alenia’s C-27J. The C-27J team eventually won the delayed decision in June 2007, and prevailed in the subsequent contract protests from their rivals. What remained unclear was exactly what they had won. The joint-service decision and contract announcement didn’t end the inter-service and Congressional politicking, and the contractor side was equally fractious. This FOCUS article covers the JCA competition, and subsequent developments – including the Pentagon’s 2012 push to end the program, and sell its planes.

Israel’s AH-64A Attack Helos Get Custom Upgrades – Despite the USA

Israel’s attack helicopter fleet still flies AH-1 Cobras, but larger and more heavily armored AH-64 Apache helicopters began arriving in 1990, and have distinguished themselves in a number of war since. The country received 44 AH-64A helicopters from 1990 – 1993. Additional buys, conversions, and losses placed the fleet at 45 helicopters as of Flight Global’s World Air Forces 2013 report, split between AH-64As and more modern AH-64D Longbows.

The AH-64D Longbow’s sophisticated mast-mounted radar can quickly pick up tanks and other dangerous targets, but isn’t designed to distinguish civilians from combatants, or to hover close over the deck in highly populated areas. Confronted by asymmetrical urban warfare and budget priority issues, and faced with a lack of cooperation from the Obama administration, the IAF decided in 2010 to forego AH-64D upgrades for their remaining helicopters. On the other hand, the type’s consistent usefulness has led Israeli to make extensive improvements of their own, to the point where Israel has effectively created their own improved AH-64A configuration…

Canada Up-Armoring its LAV-IIIs

LAV-III, FOB Robinson

Original Post date: December 3, 2008
The Government of Canada recently awarded “EODC Engineering, Developing and Licencing Inc.” of Ottawa, Canada C$ 81.5 million (about $65.5 million ) worth of contracts to provide for add-on-armour kits, modules and spares for its LAV III wheeled armored personnel carriers. LAV-III vehicles are known as Piranha-III in Europe, and are the base platform for the USA’s Stryker family of vehicles. Canadian LAV-IIIs have seen extensive use on the front lines of Afghanistan, where they have both achieved important successes and demonstrated key limitations.

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.
