The Russian-made Kamov Ka-28 (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.

An air defense identification zone (ADIZ) is airspace over land or water in which the identification, location, and control of civil aircraft is performed in the interest of national security.
