The Boeing Vertol CH-46 Sea Knight is a medium-lift tandem-rotor transport helicopter, furnished with a set of counter-rotating main rotors in a tandem-rotor configuration. It was typically powered by a pair of General Electric T58 turboshaft engines, which were mounted on each side of the rear rotor pedestal; power to the forward rotor was ...

The M28A1E1/M28A2 was fitted to the AH-1Q, while the M28A3 (no developmental variation known) was fitted to the AH-1P/S helicopter. [66] [67] There is the possibility that the M28A2 could have been the first unit designed to work with the XM128/M128 Helmet Sight System (HSS) developed primarily for use with TOW armed AH-1s.

Tandem-rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single-rotor helicopter uses some of the engine power to counter the torque. [1] An alternative is to mount two rotors in a coaxial configuration.
