The Russian-made Kamov Ka-28 (NATO Designation: 'Helix-A') is a modification of the Kamov Ka-27; specifically, the Ka-28 is the export version of the Ka-27PL.  The twin-engine Ka-28 uses the TV3-117VK turboshaft engine as opposed to the Ka-27's TV3-117VMA.

The Ka-28 is a Russian Naval anti-submarine helicopter.  It is capable of tracking and destroying surfaced and submerged submarines to a depth of 500 m.  Operations can be in day or night in any weather condition; in addition, the main rotor blades are foldable for storage and transport.
