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.

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.

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.

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.

Super Hornet Fighter Family MYP-III: 2010-2018 Contracts

The US Navy flies the F/A-18 E/F Super Hornet fighters, and has begun operating the EA-18G Growler electronic warfare & strike aircraft. Many of these buys have been managed out of common multi-year procurement (MYP) contracts, which aim to reduce overall costs by offering longer-term production commitments, so contractors can negotiate better deals with their suppliers.

The MYP-II contract ran from 2005-2009, and was not renewed because the Pentagon intended to focus on the F-35 fighter program. When it became clear that the F-35 program was going to be late, and had serious program and budgetary issues, pressure built to abandon year-by-year contracting, and negotiate another multi-year deal for the current Super Hornet family. That deal is now final. This entry covers the program as a whole, with a focus on 2010-2015 Super Hornet family purchases. It has been updated to include all announced contracts and events connected with MYP-III, including engines and other separate “government-furnished equipment” that figures prominently in the final price.

The HISS Harrier Support Program

The USA’s AV-8B Harrier IIs have gone from the most accident-prone fighter aircraft in the fleet to a much safer jet whose hover capability and LITENING surveillance and targeting pods proved extremely effective in the urban warfare scenarios of Iraq. In 2007, the USA, Italy and Spain signed a Harrier Integrated Supply Support (HISS) performance-based support deal, worth up to $400 million.

Is this a step forward in terms of contracting for support? Is the British contracting model of comprehensive through-life support on its way across the Atlantic? The answers are yes, and not exactly.

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.

Morocco’s Air Force Reloads: And Now, The Training…

Morocco’s combat air force currently flies 2 squadrons of old F-5 fighters, and 2 squadrons of only slightly newer Mirage F1s. T-37 light jets serve as high-end trainers. Their neighbor and rival Algeria flies MiG-23s of similar vintage, but the Force Aérienne Algérienne also flies SU-24 Fencer and SU-25 Frogfoot strike aircraft, plus even more modern and capable MiG-29s, and is receiving multi-role SU-30MKAs as part of a multi-billion dollar weapons deal with Russia.

Morocco can’t beat that array. Instead, they’re looking for replacement aircraft and upgrades that will prevent complete overmatch, and provide a measure of security. Initially, they looked to France, but key reversals have handed most of this modernization work to the United States.

$1.1B to Upgrade Turkish F-16 fleet

The Turkish and US governments signed a letter of offer and acceptance (LOA) on April 26/05 for the $1.1-billion modernization of 117 Turkish Air Force F-16s to a common avionics configuration. December 2006 saw a $635.1 million contract under that framework issued to Lockeed Martin.

The upgrade will create a common avionics configuration for the service’s fleet of F-16 Block 40 and 50 aircraft. More than 200 F-16 aircraft make up the backbone of Turkey’s current fighter fleet. Systems to be integrated on Turkey’s upgraded F-16s include:

Lockheed & Mitsubishi’s F-2 Fighter may be replaced with ATD-X (X-2)

Japan already produces F-15J Eagle aircraft under license from Boeing, and in 1987 they selected Lockheed Martin F-16 fighter jet as the basis for a “local” design that would replace its 1970s era F-1s. The aim was to produce a less expensive fighter that would complement its F-15s, provide a bridge for key aerospace technology transfers, and give Japan’s aerospace industry experience with cutting-edge manufacturing and component technologies.

The F-2’s increased range is very useful to Japan, given their need to cover large land and maritime areas. Nevertheless, a combination of design decisions and meddling from Washington ensured that these fighters ended up costing almost as much as a twin-engine F-15J Eagle, without delivering the same performance. As a result, production ended early, and the 2011 tsunami made Japan’s fleet even smaller. The remaining fleet will continue to receive upgrades, in order to keep them combat capable for many years to come.
