Equipped with an Emergency Escape System, severing the rotor blades to allow the crew of the 3-place aircraft to escape topside; afterward, it enters the Airplane Configuration.

 

Hover flight is not possible; take-off and landings are STOL/CTOL.  In addition to the turbofan propulors, the main transmission and tail rotor are powered by General Electric T58-GE-5 / T58-GE-10 engines.  The equipped main rotor is that of the S-61 (H-3) while a conventional 5-blade tail rotor is used.
