Four defence contractors and their partners are lining up to put in bids to build the US Air Force’s next-generation fighter trainer, via the T-X programme.
The competitors include partnerships of Alenia Aermacchi/General Dynamics, BAE Systems/Northrop Grumman and Korea Aerospace Industries/Lockheed Martin – which plan to pitch versions of existing aircraft – and Boeing, which will propose a clean-sheet design in partnership with Saab.
Analysts say that while little is known about Boeing’s proposal, the other candidates give the USAF a broad range of options, both in terms of price and performance.
“They all have a good product, and I don’t think anyone has a particular advantage,” says Mark Gunzinger, from the Center for Strategic and Budgetary Assessments.
The T-X programme calls for the acquisition of 350 aircraft to replace the USAF’s 1960s-era Northrop T-38 Talons, which lack the technology and performance needed for fifth-generation fighter training, the USAF’s Air Education and Training Command tells Flightglobal.
As of now, the requirements allow for a single- or twin-engined aircraft with either a side stick – like Lockheed Martin's F-22 and F-35 – or a centre stick. The service is also considering either a supersonic or subsonic trainer, but says the cockpit displays should “closely replicate” fifth-generation aircraft.
The service’s fiscal year 2015 budget proposal would inject $667 million into T-X through FY2019, and it envisions spending another $581 million in later years. Initial operational capability is expected around 2023 for a US-built aircraft.
Congress must approve the budget, but observers expect it will get the green light.
“This doesn’t have a whole lot of controversy associated with it,” says Gunzinger.
Richard Aboulafia, vice-president of Teal Group, calls the KAI/Lockheed T-50 Golden Eagle the “most capable” option – but also probably the most expensive to buy and operate.
Lockheed declines to discuss prices with Flightglobal, but Aboulafia estimates the T-50’s flyaway cost will be $26 million.
Currently built in South Korea and flown by that country’s air force, the T-50 was designed specifically to train fifth-generation fighter pilots, Lockheed says.
The aircraft, which has been in service since the mid-2000s, can reach Mach 1.5 and pull 8g, Lockheed says. The type also has an afterburner behind its single General Electric F404 engine.
“A student doesn’t need extensive training in the operating squadron to learn high-speed manoeuvring,” says the company.
“If the [USAF] has the budget, and they want [pilots] to go as easily as possible into an F-22 or F-35, the T-50 is the choice,” says Aboulafia.
He estimates the least expensive choice, at about $21 million each, as the BAE/Northrop Hawk advanced jet training system, which is derived from a subsonic aircraft originally introduced in the 1970s.
“If you want to put a pilot in the air and give him good cockpit training at the lowest cost, [the Hawk is] the way to do it,” says Aboulafia.
The aircraft BAE will pitch to the USAF will be similar to the Hawk T2 operated by the UK Royal Air Force, and also ordered by Oman and Saudi Arabia. Used to prepare pilots for types including the Eurofighter Typhoon, the aircraft has a Rolls-Royce Turbomeca Adour 951 turbofan with full authority digital engine control software and can reach 555kt (1,030km/h), BAE says.
BAE notes the T2 also has advanced “simulation architecture” that emulates sensors and communicates with other aircraft to mimic threats.
Operators of earlier Hawk variants include Australia, Bahrain, Canada, Finland, India, Indonesia, Kuwait, Malaysia, Oman, Saudi Arabia, South Africa and the United Arab Emirates, according to Flightglobal’s MiliCAS database. The US Navy also flies the Boeing/BAE T-45 Goshawk, which is derived from the same design.
“Some competitors build a few airplanes, but nobody [has] anywhere close to [our] customer domain,” BAE says.
Aboulafia says Alenia Aermacchi’s T-100 – a derivative of its M-346 trainer – holds the middle ground.
The aircraft are “very modern”, have “great flying characteristics” and will likely cost about $24 million each, he estimates. The M-346 is powered by two Honeywell F124-200 turbofans, can pull 8g and reach 590kt at 5,000ft (1,520m), according to Alenia Aermacchi. The type is operated by Italy and Singapore, and has also been ordered by Israel and Poland.
“It’s a good compromise,” says Aboulafia of the T-100. “The market has spoken to that. Israel and Singapore [are] two of the most prestigious militaries around.”
Very little is known about the Boeing/Saab design, and Boeing refers questions to a press release issued last December.
“Teaming with Saab will bring together our companies' formidable technical expertise, global presence and willingness to present an adaptable and affordable advanced pilot training solution,” says Boeing.
