Five Year Extension on Paveway-II Missile Production

Paveway II kits convert standard Mk 80 family free-fall bombs into laser-guided weapons. Each guidance kit consists of a computer control group (CCG) guidance system with a semi-active laser seeker and pneumatically-controlled guidance canards for the front-end of the bomb, plus an air foil group (AFG) on the back end that provides lift and stability. Once a target is designated, laser guidance is more accurate than GPS, but it can be foiled by obscurants like fog, sandstorms, etc.

At the beginning of August 2011, the US government issued a contract worth up to $475 million…

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]

UK Tornados Biding Time

With the retirement of the RAF’s Jaguar fleet, the core of Britain’s land-based tactical air fleet rests in a pair of multinational European fighters. The new Eurofighter Typhoon is one of the top 3 air superiority fighters in the world, and enhancements are finally beginning to give it some precision strike capability. The mainstay of the existing fleet is made up of the British-Italian-German Panavia consortium’s Tornado aircraft, in both F3 air defense and GR4 low-level precision strike configurations.

The F3s are being pushed aside by the Eurofighters, but the GR4s were expected to remain in place until 2025. A 2007 effort added LITENING surveillance and targeting pods, to improve the aircraft’s close air support capabilities on the front lines of Iraq and Afghanistan. Now a GBP 253 million (about $496 million) “Capability Upgrade Strategy (Pilot)” program seeks to take the next steps, and is intermeshed with the Tornado fleet’s successful ATTAC fixed-price through-life maintenance program…

Moving Target: Raytheon’s GBU-53 Small Diameter Bomb II

The 250 pound GBU-39 Small Diameter Bomb gives American fighters the ability to carry more high-precision GPS-guided glide bombs, without sacrificing punching power against fortified targets. The initial award to Boeing was controversial, and the Darlene Druyun corruption scandal ultimately forced a re-compete of the Increment II development program. Whereas the initial GBU-39 SDB-I offered GPS-guided accuracy in a small and streamlined package, the goal of the GBU-53 SDB-II competition was a bomb that could hit moving targets in any weather, using a combination of guidance modes.

For the SDB-II competition, Boeing found itself allied with Lockheed Martin, its key opponent for the initial SDB-I contract. Its main competitor this time was Raytheon, whose SDB-II bid team found itself sharing its tri-mode seeker technology with a separate Boeing team, as they compete together for the tri-service JAGM missile award against… Lockheed Martin. So, is Raytheon’s win of the SDB-II competition also good news for its main competitor? It’s certainly good news for Raytheon, who wins a program that could be worth over $5 billion.

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.

Top Falcons: The UAE’s F-16 Block 60/61 Fighters

The most advanced F-16s in the world aren’t American. That distinction belongs to the UAE, whose F-16 E/F Block 60s are a half-generation ahead of the F-16 C/D Block 50/52+ aircraft that form the backbone of the US Air Force, and of many other fleets around the world. The Block 60 has been described as a lower-budget alternative to the F-35A Joint Strike Fighter, and there’s a solid argument to be made that their performance figures and broad sensor array will even keep them ahead of pending F-16 modernizations in countries like Taiwan, South Korea, and Singapore.

The UAE invested in the “Desert Falcon’s” development, and the contract reportedly includes royalty fees if other countries buy it. Investment doesn’t end when the fighters are delivered, either. Money is still needed for ongoing training, fielding, and equipment needs – and the UAE has decided that they need more planes, too. This DID article showcases the F-16 Block 60/61, and offers a window into its associated costs and life cycle, including dedicated equipment purchases for this fighter fleet.

Boeing’s GBU-39 Small Diameter Bomb Gets Boost

Nov 1/10: Boeing in St. Louis, MO receives a $106.4 million contract modification, exercising the Production Lot 7 (FY 2011) option for GBU-39 small diameter bombs, carriages, and technical support. At this time, the entire amount has been committed by the AAC/EBMK at Eglin Air Force Base, FL (FA8672-11-C-0034). Boeing’s Nov 9/10 release states that Lot 7 covers 2,700 GBU-39s and 280 GBU-61 carriages. Production Lots 1-5 delivered approximately 7,000 bombs and 1,200 carriages to the USAF, and Lot 6 production of 2,613 bombs and 472 carriages is more than 3 months ahead of schedule.

Unlike Raytheon’s GBU-53 SDB-II, Boeing’s SDB-I isn’t designed to attack moving targets. Instead, this GPS-guided weapon is more like the Joint Direct Attack Munition (JDAM), with a number of key design modifications. This specially shaped 250-pound bomb’s thin and pointed shape gives it extra punch against buildings and hardened targets, even though its warhead is only 50 pounds of explosive. Its pop-out glide wings and guidance set give it extended range, depending on the launching aircraft’s speed and altitude. The bombs are carried on a smart BRU-61/A 4-rack carriage, or in the internal weapon bay of planes like the F-22A Raptor. Either way, the SDB-I’s weight and compact design let aircraft carry far more smart bombs than they could otherwise.

Contracts & Events

January 5/18: Contract-FMS Boeing has been awarded a $193 million US Air Force contract by the Department of Defense (DoD), to provide GBU-39 Small Diameter Bomb Increment 1 (SBD-1) to several foreign partner nations. Saudi Arabia, Japan, Israel, the Netherlands, South Korea, and Singapore will all benefit from the deal, and 6,000 SDB 1 all-up-rounds are being produced under the modification to the original Lots 12-14 production order. Production will take place at St. Louis, Mo., and deliveries will be completed by December 2020.

April 8/16: Australia has been cleared to purchase up to 2,950 GBU-39 Small Diameter Bombs by the US State Department. The $386 million sale will include the provision of up to 50 Guided Test Vehicles (GTV) with GBU-39 (T-1)/B (Inert Fuze) as well as containers, weapons system support equipment, support and test equipment, site survey, transportation, repair and return warranties, spare and repair parts, publications and technical data, maintenance, personnel training, and training equipment. Included additionally are US Government and contractor representative engineering, logistics, and technical support services, and other related elements of logistics support.

November 12/15: Boeing has been awarded an Air Force contract modification covering Foreign Military Sales production of GBU-39 Small Diameter Bombs. The $130.1 million modification covers deliveries of the weapons to foreign partners, with the contract modification running to 2019. Israel and Italy operate the munition outside of the United States. First initial production of the SDBI began in 2005, after a controversial decision to award Boeing a production order.

The Saudis’ American Shopping Spree: F-15s, Helicopters & More

In October 2010, talks that Saudi Arabia was negotiating a $30-60 billion arms package with the USA were made official with a full multi-billion request that included 84 F-15 Strike Eagles to replace the Kingdom’s Tornado strike aircraft and/or F-15A-D fighters, upgrades for another 70 planes, about 132 UH-60 Black Hawk utility and AH-64 attack helicopters, and armaments to equip them.

This article looks at those requests, their tie-ins, the issues that are part of these potential deals, and related follow-on requests. As is often the case with DSCA announcements, years can pass between the requests and the signed contracts, but these contracts have started to roll in, alongside other significant buys.

F-15SG: Singapore’s RSAF Decides to Fly Like An Eagle

At the dawn of the 21st century, Singapore decided that it needed a new aircraft to replace its often-upgraded A-4SU Super Skyhawks. This was hardly surprising; John McCain had been flying an older model A-4 Skyhawk when he was shot down during the Vietnam War. The decision to require a twin-engine aircraft eliminated the JAS-39 Gripen and F-16E/F Block 60 from the competition, and the F/A-18E/F Super Hornet and Sukhoi Su-30 family were also scratched. That left just 3 finalists: Boeing’s F-15 Strike Eagle, France’s Rafale, and the Eurofighter Typhoon. Limited air-to-ground capabilities and a slow upgrade schedule splashed the Eurofighter, leaving just 2 contenders still flying.

September 2005 releases tapped Boeing as the winner, and the deal was done in December 2005. The order eventually rose to 24 planes, which was good news for Boeing: Singapore’s F-15SGs, and South Korea’s 2 F-15K orders, kept the assembly line open long enough for a huge win in Saudi Arabia, and the prospect of more orders. Singapore has legitimate grounds to argue that they currently fly the world’s most advanced version of the F-15 Strike Eagle…

Longshot: A Swooping HAAWC for Torpedoes

Mk54 HAAWC

American maritime patrol aircraft currently carry torpedoes as part of their armament, which serve as key weapons against enemy submarines. As any high-diver of cliff-jumper knows first hand, however, water can feel surprisingly solid after a long fall. Torpedoes still have to be released from low altitude, typically 100 feet or less above the waves. Two recent developments, however, are making this approach less practical for the US military. One is tests of sub-launched anti-air missile systems, using modified short-range air-air missiles that do not require radar guidance. The other is its selection of the 737-based P-8A Poseidon as its next maritime patrol and surface surveillance aircraft. The P-8A can perform low swoops if necessary, but its airframe is really optimized for cruising at altitude.

As these trends developed, someone in the US military asked the logical next question:
