Airbus has revealed a classified stealth unmanned aerial vehicle (UAV) demonstrator aircraft on 5 November during the company’s annual Trade Media Briefing at Manching in southern Germany.
The Airbus Defence & Space has been developing the Low Observable UAV Testbed (LOUT) aircraft secretly for 10 years for the German defence ministry.
“Nobody is aware of what we have been doing here – this is a classified project that was started as long ago as 2007. The development contract was awarded in 2010, and the LOUT has been developed in Manching and Bremen in a Skunk Works approach,” said Mario Hertzog, German Low Observable (LO) Demonstrator Head.
The LOUT is designed to be a subsonic diamond-shaped Low Observable vehicle that measures 12 m wingspan x 12 m length and weighs four tons.
The 6th generation LOUT fighter is designed to offer visual, acoustic, radar, and infrared stealth against ground-based threats.
The aircraft is designed with Radar absorbing materials, low-radar cross section (RCS) engine inlets, structural cooling technologies, minimised gaps between surfaces, and unspecified LO coatings to optimise stealth technology.
