The Hughes Model 369 (US Army designation OH-6A) was an American turbine-powered light observation helicopter first flown in 1963. The Hughes Model 369 was powered by an Allsion T63-A-5A shaft-turbine engine providing a top speed of 230 kmh and a range of 673 km. The Hughes Model 369 carried a crew of two side-by-side in the front of the cabin and has folded seats behind to accommodate four fully-equipped soldiers. The Hughes Model 369 had provision for carrying an armaments package on the port side of the fuselage, comprising a twin machine-gun or XM-75 grenade launcher. Later the Hughes Model 369 was modified and produced by McDonnell Douglas as the McDonnell Douglas Model 369 OH-6 Cayuse. Research Hughes Model 369
