A-10 over Germany
(click to view full)

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 upgrade requirements into one 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.

In the latest updates, the A-10C program’s $2 billion re-winging effort became a higher priority, as wing cracking became a problem for the entire A-10 fleet. Now a longer-term $1.7 billion general maintenance contract for the fleet has been issued to 3 firms, per new defense acquisition rules, and contracts are begining to flow…

B-2 drops JDAM
(click to view full)

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. The DID FOCUS Article looks at the transformational history of the JDAM GPS-guided bomb program, the ongoing efforts to bring its capabilities up to the level of weapons like Israel’s Spice and Raytheon’s Enhanced Paveway, and the contracts issued under the JDAM program and its derivatives.

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 US Air Force did use 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. The latest news involves FY 2009-2010 budget updates, plus a $72 million contract for 2,925 JDAM kits…

PAF F-16A drops Mk.82s
(click to view full)

On June 28/06, the US DSCA notified Congress via a series of releases of its intention to provide Pakistan with a $5.1 billion Foreign Military Sales package to upgrade the F-16s that serve as the PAF’s top of the line fighters. Some of these items had been put on hold following the October 2005 earthquake in Pakistan & Kashmir, but the request for 36 new F-16 Block 50/52s is now going ahead following the required 30-day review period, along with new weapons, engine modifications, 60 F-16 upgrade kits that would cover Pakistan’s older F-16 A/Bs plus other aircraft it might buy second-hand, and related equipment.

These items are detailed below, along with controversies the proposed sales have created, and some of the conditions attached to the sale by the US government. By the end of July 2008, Pakistan was expected to have its first 10 planes. The first new-build F-16, on the other hand, just had its acceptance ceremony this month…

• Item 1: 36 New F-16 Block 50/52s – $3 billion
• Item 2: Weapons for the New F-16s – $650 Million
• Item 3: F-16A/B Mid-Life Update Modification Kits – $1.3 billion
• Item 4: F-16A/B Engine Modifications & UP/STAR – $151 Million

“Grand Slam”
(click to view full)

During the Second World War, attacking heavily protected targets like U-boat pens and protected “V-weapon” facilities was a key challenge. Enter a brilliant British engineer named Barnes Wallis, fresh off the dam-busting “Upkeep” bouncing bomb. His next trick was a 12,000 pound weapon called the “Tallboy,” a streamlined, spin-stabilized bomb with an estimated terminal velocity of over Mach 3.5 when dropped from 20,000 feet. That mass, at that speed, carrying 5,200 pounds of Torpex D1 explosive, made a crater 80 feet deep x 100 feet across when it hit. By 1945, Wallis’ next “Earthquake bomb” was in production – the 22,000 pound “Grand Slam.” They made short work of U-boat pens.

These bombs went out of fashion with the advent of nuclear weapons, but if you wait long enough, fashion comes around again. It may even be accelerated, as concerns rise about Iran’s nuclear program…

Death from above
(click to view larger)

The Viper Strike began life as the BAT – a canceled munition option for ground-fired ATACMS missiles. After USAF Predator UAVs armed with Hellfire missiles began to show promise in the Global War on Terror, however, US Army planners began to examine their options. Could they place a similar capability in the hands of Army ground commanders? In July 2002, these examinations led to the award of a 90-day contract to demonstrate the possibility of BAT deployment on a modified U.S. Army RQ-5 Hunter UAV.

Those tests went well, and Viper Strikes are currently carried by RQ-5B Hunter UAVs in Iraq – see this video of a Viper Strike in testing [MPG, 13.2 MB]. The weapon’s small size (3 feet long, 44 pounds) and special advantages in urban fights, mountainous terrain, etc. give it a chance of spreading to other platforms. Special Operations Command has shown interest, but without front-line deployment, progress has been very slow.

Is the Viper Strike a case of “the right weapon at the right time”? Or a case of “caught betwixt and between”? A recent announcement may offer some hope for this innovative weapon…

F-16F “Desert Falcon”
(click to view full)

The F-16 has become what its designers intended it to be: a worthy successor to the legendary P-51 Mustang whose principles of visibility, agility, and pilot-friendliness informed its design. It is no exaggeration to call it the defining fighter of its age, the plane that many people around the world think of when they think “fighter.” The aircraft’s ability to handle future adversaries like the thrust-vectoring MiG-29OVT/35 and advanced surface-air missile systems is in question, but upgrades have kept F-16s popular. The planes have been produced in several countries around the world, thanks to licensing agreements, but this does not change their status as the American defense industry’s greatest success story of the last 40 years.

The most advanced F-16s in the world, however, are not American. That distinction belongs to the United Arab Emirates, whose F-16 E/F Block 60s are a generation ahead of the F-16 C/D Block 50/52+ aircraft that form the backbone of the US Air Force and many other fleets around the world. The Block 60 has been described as a lower-budget alternative to the forthcoming F-35A Joint Strike Fighter – and is being treated as such in countries like India and the Netherlands, as they contemplate their future fighter needs.

The UAE invested in the type’s development, and with that investment comes inevitable fielding, training, and equipping needs. This DID article showcases the F-16 E/F “Desert Falcon,” and offers a window into its associated costs. The latest items include a first-ever attendance at Red Flag, and some interesting information about the plane’s AN/APG-80 AESA radar…

Paveway-IV components
(click to view larger)

In 2003, Raytheon UK operation won the GBP 120 million pound contract to develop and produce Paveway IV, beating Boeing’s INS/GPS guided JDAM. The GPS/INS and laser-guided 500-pound bombs are a British project, and will add a number of other enhancements including longer range than previous Paveway versions.

The British military had wanted to deploy Raytheon’s latest Paveway IV bombs in Afghanistan by September 2007, on board its newly-upgraded Harrier GR9 aircraft. Unfortunately, testing problems with the Thales UK’s Aurora fuze removed that option. The MoD found a way to deploy the smart bombs with lesser capabilities by December 2007, and eventually deployed full Paveway IVs on its Harriers in Afghanistan. The weapon is now ready for use with its Tordano GR4 strike aircraft, which are replacing the Harriers…

FAC Kfir C7

Colombia’s narco-terrorist FARC army has reportedly lost some of its military shine recently, thanks to years of unswerving pressure from the Colombian army. Much of that pressure has been led by the popular President Uribe, who has apparently ruled out a bid for constitutional amendments and an attempt at a 3rd term of office, but allowed a related referendum proposal to go forward. Delays to that proposal now appear to be solidifying Uribe’s term limit exit. Before that 2010 exit, however, a special tax levied in 2006 is set to finance about $4 billion worth of military hardware, and add stronger backing to those military gains.

Colombia’s El Tiempo newspaper reports that the deals are meant to solidify and modernize the military, and will include a wide variety of equipment from American, French, German, Israeli, and Russian suppliers. Additional research has added more details, and key deliveries have now begun.

F-15E firing flares:
“Splash Two in Singapore!”
(click to view full)

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-16 E/F Block 60 from the competition, and the F/A-18 E/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-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 12-plane, $1+ billion order (est. $1.4-1.8 billion) was good news for Boeing: Singapore’s F-15SGs, and South Korea’s 40-60 plane F-15K order, are keeping the assembly line open for this 2-seat, multi-role fighter.

The F-15SG will be an advanced version of the U.S. Air Force’s F-15E Strike Eagle, with minor customization to Singapore’s specifications and the most up-to-date avionics available. The higher-thrust GE F110 engine will be used in place of the Pratt & Whitney F100 engines that power some F-16s and most F-15s. AN/APG-63v3 AESA radars will be included, and there are rumors that a number of Israeli electronics and self-defense systems will be part of the F-15SG as well. Sniper XR surveillance & ground targeting pods, and IRST systems built in for air-air engagements, will also be added to Singapore’s standard equipment list.

With all of these features built into its fighters, Singapore has legitimate grounds to argue that it will be flying the world’s most advanced version of the F-15 Strike Eagle. A follow-on order increased the numbers bought, and now the first planes have been delivered…

RQ-7 Shadow
(click to view full)

In 2007, US Army RQ-7 Shadow battalion-level UAVs saw their use increase to up 8,000 flight hours per month in Iraq, a total that compares well to the famous MQ-1 Predator. Those trends have continued as workarounds for the airspace management issues that hindered early deployments become more routine. Some RQ-7s are even being used to extend high-bandwidth communications on the front lines.

The difference between the Army’s RQ-7 Shadow UAVs and their brethren like the USAF’s MQ-1A Predator, or the Army’s new MQ-1C Sky Warriors, is that the Shadow has been too small and light to be armed. Larger RQ-5 Hunters have been tested with Viper Strike mini-bombs, and RQ-7s will certainly be eligible for NAVAIR’s 5-6 pound Spike missile project. Meanwhile, as “CENTCOM Looks to Boost ISR Capabilities in 2008-2009” explained, UAVs can still pack a punch without weapons. UAVs can provide targeting data to M30 GPS-guided MLRS rockets, long-range ATACMS MLRS missiles, or GPS-guided 155mm Excalibur artillery shells – as long as those weapons are (a) appropriate and (b) within range.

Using an ATACMS missile to take out an enemy machine gun position seems a bit silly, but that’s exactly the sort of help that could really make a difference to troops on the ground. Precision weapons can also be dropped by fighters or bombers, but their $10,000 – $25,000 cost per flight hour is prohibitive, they require extensive planning processes to use, and their declining numbers affect their potential coverage and response times. With NAVAIR’s mini-missile still in development, and missions in Afghanistan occurring beyond artillery support range, arming the Army’s Shadow UAVs has become an even more important objective. So important, in fact, that it spawned a bright idea: what if smaller UAVs could carry and drop the Army’s 81mm mortar ammunition, which weighs just 9-10 pounds? Enter General Dynamics’ RCFC kit….
