Sikorsky S-72 RSRA ![]() S-72 RSRA
The 1976 RSRA used the H-3/S-61 rotor system and engines on a new fuselage, similar to the S-67. The crew were seated on seats with a rocket extraction system (the blades would be blown off at the start of ejection sequence). Could be flown with wings and two GE TF-34s. Was flown in all combinations, even with no tail rotor.
