Ka-29 And KA-28 Combat Transport Helicopter Tecnology Sonar System

The Ka-29 combat transport helicopter is designed to airlift armed marines from warships, provide close air support to airborne troops, engage naval and ground targets (including armoured ones), and transport cargo. It can be operated from various ship types and airfields in all latitudes, by day and night, in any weather. Variants The Ka-29 can be configured into a combat or cargo version. The conversion can be performed directly in service units.

The helicopter featured an effective navigation, targeting and communication suite. Its armament in the Ka-29TB assault version comprised anti-tank guided missiles, gun pods, unguided rockets, free-fall bombs and submunitions dispensers. The transport version could accomodate 16 fully-armed troops or carry outsize loads weighing up to 4000kg on a sling and was armed with a rapid-firing 7.62-mm machine-gun. The State acceptance trials were completed in May 1979 and production began in 1984.

Armament

The Ka-29 combat version is equipped with the onboard sighting system supporting employment of the following weapons: up to eight Shturm ATGMs; up to 80 S-8 rockets in the B8-V20-A pods, air bombs, incendiary tanks, and the UPK-23-250 gun mounts. The transport version carries a 7.62mm nose machine gun with 1,800-round ammunition load. The cargo compartment accommodates up to 16 troops with side arms, or four stretcher casualties and seven sitting casualties with one medical attendant, or up to 2,000kg cargo.

The helicopter can also be fitted with rescue equipment for maritime search-and-rescue operations. Up to 4,000kg cargo can be carried on external hardpoints.

Ka-28 ASW Helicopter

The Ka-28 helicopter is designed to search for, detect, track, and engage surfaced and submerged submarines moving at a speed of up to 75 km/h, at a maximum depth of 500 m. The Ka-28 is capable of long endurance maritime ASW missions with no reference waypoints, in any climate and season, by day and night, in all weather conditions, at a range of over 200 km, at Sea State up to 5.

The Ka-28 is capable of autonomous operation from light displacement vessels, and group operation from aircraft carriers. Main rotor blades are folded for shipborne parking. The Ka-28’s landing gear is designed for taking off from/landing on a rocking deck. Ditching is facilitated by inflatable ballonets. The helicopter can be configured to operate in the search, search/attack, or attack variants.

The helicopter's avionics suite includes an integrated flight navigation system and a sighting system (a surveillance radar and a sonar system). The avionics suite provides navigation of the helicopter to a preset area in any weather conditions; submarine detection with the help of the sonar system and the magnetometer; weapons control; return flight to the mother ship; and landing approach. A special receiver/display unit is used for automatic monitoring of sonobuoys on the water surface. The unit provides surface and underwater target search, detection, and location.

Armament
The Ka-28 armament includes APR-3E ASW missiles, OMAB-25-12D and OMAB-25-8N marine marking bombs.
