Paladinhawk
From NSwiki, the NationStates encyclopedia.
The Paladinhawk is a SH-60 Knighthawk adjusted to use Piasecki's VTDP (Vectored Thrust Ducted Propeller) compound helicpter system. This system allows the helicopter to fly at much faster speeds than a normal helicopter can.
The Paladinhawk is in use in the Syskeyian Army, Navy and (I think) Air Force.
