Lockheed Martin Skunk Works is designing a next-generation high-altitude, long-endurance (HALE) surveillance airplane, known internally as RQ-X or UQ-2, as an optionally-manned successor to the U-2 and Northrop Grumman RQ-4 Global Hawk.
U-2 programme officials told reporters at the Skunk Works headquarters in Palmdale, California, that its engineers have been mulling designs for stealthy HALE platform that would combine the best of the U-2 and its unmanned rival, the Global Hawk.
The advanced research and development arm of Lockheed is essentially pursuing an improved version of the U-2, which is powered by the same General Electric F118 engine and optimised to fly at 70,000ft or higher. It would carry many of the same sensors, since those are already calibrated for use at that altitude. The biggest difference will be the aircraft’s low-observable characteristics.
“Think of a low-observable U-2,” says Scott Winstead, Lockheed’s U-2 strategic development manager. “It’s pretty much where the U-2 is today, but add a low-observable body and more endurance.”
The disclosure comes on the 60th anniversary of the U-2 programme, and as stagnant defence budgets force the Pentagon to choose between retiring the U-2 or Global Hawk.
The US Air Force has no formal requirement for a U-2 successor, nor has it released a time frame for when it might start pursing a next-generation HALE platform.
