Aging Aircraft: USAF F-15 Fleet Sees Renewed Interest

“Array of Aging American Aircraft Attracting Attention” discusses the issues that accompany an air force whose fighters have an average age of over 23.5 years – vs. an average of 8.5 years in 1967. One of the most obvious consequences is the potential for fleet groundings due to unforseen structural issues caused by time and fatigue. That very fear is responsible for the #1 priority placed on bringing new KC-X aerial tankers into the fleet to complement the USA’s 1960s-era KC-135 Stratotankers.

It can also affect the fighter fleet more directly.

Following the crash of a Missouri Air National Guard F-15C aircraft Nov 2/07 (see crash simulation), the US Air Force suspended non-mission critical F-15 flight operations on Nov 3/07. While the cause of that accident is still under investigation, preliminary findings indicate that a structural failure during flight may have been responsible. In response, Japan suspended its own F-15 flights, which left them in a bit of a bind – even as Israel’s F-15s joined them on the tarmac. As the effects continue to spread and the USAF and others continue to comment on this situation, DID continues to expand its coverage of this bellwether event. A conditional restoration of the American F-15A-D fleet to flight status was soon overturned by the re-grounding of that fleet as a result of the report’s conclusions – a status that remains only been partially lifted. Meanwhile, the accident report has been released (compete with video dramatization) and the status of the remaining aircraft will have significant implications for the USAF’s future F-15 fleet size. Not to mention its other procurement programs.

Then, too, this is America. Now there’s a lawsuit.

F-35 Lightning: The Joint Strike Fighter Program

The $382 billion F-35 Joint Strike fighter program may well be the largest single global defense program in history. This major multinational program is intended to produce an “affordably stealthy” multi-role fighter that will have 3 variants: the F-35A conventional version for the US Air Force et. al.; the F-35B Short Take-Off, Vertical Landing for the US Marines, British Royal Navy, et. al.; and the F-35C conventional carrier-launched version for the US Navy. The aircraft is named after Lockheed’s famous WW2 P-38 Lightning, and the Mach 2, stacked-engine English Electric (now BAE) Lightning jet. Lightning II system development partners included The USA & Britain (Tier 1), Italy and the Netherlands (Tier 2), and Australia, Canada, Denmark, Norway and Turkey (Tier 3), with Singapore and Israel as “Security Cooperation Partners,” and Japan as the 1st export customer.

The big question for Lockheed Martin is whether, and when, many of these partner countries will begin placing purchase orders. This updated article has expanded to feature more detail regarding the F-35 program, including contracts, sub-contracts, and notable events and reports during 2012-2013.

Global F/A-18 Hornet Fleets: Keeping ‘Em Flying

The F/A-18 Hornet is the F/A-18 E/F Super Hornet‘s predecessor, with the first models introduced in the late 1970s as a spinoff of the USAF’s YF-17 lightweight fighter competitor. Hornets are currently flown by the US Marine Corps as their front-line fighter, by the US Navy as a second-tier fighter behind its larger F/A-18 E/F Super Hornets, and by 7 international customers: Australia, Canada, Finland, Kuwait, Malaysia, Spain, and Switzerland. The USA’s aircraft were expected to have a service life of 20 years, but that was based on 100 carrier landings per year. The US Navy and Marines have been rather busy during the Hornets’ service life, and so the planes are wearing out faster.

This is forcing the USA to take a number of steps in order to keep their Hornets airworthy: replacing center barrel sections, re-opening production lines, and more. Some of these efforts will also be offered to allied air forces, who have their own refurbishment and upgrade programs.

Super Tucano Counter-Insurgency Plane Makes Inroads in Africa

Embraer’s EMB-314 Super Tucano trainer and light attack turboprop continues to rack up global orders, solidifying its position as the globe’s pre-eminent manned counter-insurgency aircraft. The latest order set of about $180 million expands the plane’s footprint into 3 African states: Angola, Burkina Faso, and Mauritania. They join Brazil, Chile, Colombia, the Dominican Republic, Ecuador, and Indonesia as customers for this aircraft.

The Super Tucano is known as the A-29 or ALX in Brazil, but abroad, it’s the EMB 314 successor to Embraer’s widely-used EMB 312 Tucano trainer. A-29 is better for marketing, though, and Embraer is trying to shift the designation. The Super Tucano offers better flight performance than the EMB 312 Tucano, plus armoring and wing-mounted machine guns, weapons integration with advanced surveillance and targeting pods, precision-guided bombs, and even air-to-air missiles. This makes it an excellent territorial defense and close support plane for low-budget air forces, as well as a surveillance asset with armed attack capability. Brazil uses it this way, for instance, alongside very advanced EMB-145 airborne radar and maritime patrol jet platforms. Meanwhile, in Africa…

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…

Raytheon’s APG-79 AESA Radars

The AN/APG-79 Active Electronically Scanned Array (AESA) radar began life as a replacement. Initial F/A-18 E/F Super Hornet production batches installed Raytheon’s all-weather, multimode AN/APG-73, but the APG-79 has intrinsic technical features that offered revolutionary increases in capability, reliability, image resolution, and range.

Unlike the APG-73 that equipped the first Super Hornets, the APG-79’s AESA array is composed of numerous solid-state transmit and receive modules that are fixed in place, eliminating a common cause of breakdowns. To move their beams, they rely on electronic changes in each module’s transmissions, creating useful interference patterns in order to aim, focus and shape their output. Other system components include an advanced receiver/exciter, ruggedized commercial-off-the-shelf (COTS) processor, and power supplies. With its open systems architecture and compact COTS parts, it changes what both aircrews and maintenance staff can do with a fighter radar – and does so in a smaller, lighter package.

France’s Rafale

Will Dassault’s fighter become a fashionably late fighter platform that builds on its parent company’s past successes – or just “the late Rafale”? It all began as a 1985 break-away from the multinational consortium that went on to create EADS’ Eurofighter. The French needed a lighter aircraft that was suitable for carrier use, and were reportedly unwilling to cede design authority over the project. As is so often true of French defense procurement policy, the choice came down to paying additional costs for full independence and exact needs, or losing key industrial capabilities by partnering or buying abroad. France has generally opted for expensive but independent defense choices, and the Rafale was no exception.

Those costs, and associated delays triggered by the end of the Cold War and reduced funding, proved to be very costly indeed. Unlike previous French fighters, which relied on exports to lower their costs and keep production lines humming, the Rafale has yet to secure a single export contract – in part because initial versions were hampered by impaired capabilities in key roles. The Rafale may, at last, be ready to be what its vendors say: a true omnirole aircraft, ready for prime time on the global export stage. The question is whether it’s too late. Rivals like EADS’ Eurofighter, Russia’s Su-27/30 family, and the American “teen series” of F-15/16/18 variants are all well established. Meanwhile, Saab’s versatile and cheaper JAS-39 Gripen remains a stubborn foe in key export competitions, and the multinational F-35 juggernaut is bearing down on it.

Eurofighter’s Future: Tranche 3, and Beyond

The multi-national Eurofighter Typhoon has been described as the aerodynamic apotheosis of lessons learned from the twin engine “teen series” fighters that began with the F-14 and F-15, continued with the emergence of the F/A-18 Hornet, and extended through to the most recent F/A-18 Super Hornet variants. Aerodynamically, it’s a half generation ahead of all of these examples, and planned evolutions will place the Eurofighter near or beyond parity in electronic systems and weapons.

The 1998 production agreement among its 4 member countries involved 620 aircraft, built with progressively improved capabilities over 3 contract “tranches”. By the end of Tranche 2, however, welfare state programs and debt burdens had made it difficult to afford the 236 fighters remaining in the 4-nation Eurofighter agreement. A 2009 compromise was found in the EUR 9 billion “Tranche 3A” buy, and the program has renewed its efforts to secure serious export sales. Their success will affect the platform’s production line in the near term, and its modernization plans beyond that.

Adir Who? Israel’s F-35i Stealth Fighters

In an exclusive June 2006 interview, Israeli Air Force (IAF) chief procurement officer Brigadier-General Ze’ev Snir told Israeli media that the F-35 Joint Strike Fighter was a key part of their IAF recapitalization plans, and that Israel intended to buy over 100 of the fighters to replace their fleet of over 300 F-16s.

Since then, however, the expected cost of that purchase has more than doubled. Israel’s F-35 contract had to deal with that sticker shock, with issues like the incorporation of Israeli technologies and industrial work, and with major schedule slips in the core F-35 program. Israel was even contemplating delaying its purchase, which would have removed an important early adopter for the Lightning II. In the end, however, Israel decided to forego other fighter options, and became the first foreign buyer of operational F-35s. So, how is the “F-35i Adir” shaping up?

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.
