The unexpected depth of underwater destruction of Vietnam's Ka-28

The Ka-28 is considered one of the most fearsome anti-submarine helicopters in the world. It has unique features that no other American or European helicopter has.

The Ka-28 helicopter uses coaxial rotors, made of composite materials and using anti-icing agents. The Ka-28 can operate in cold seas, take off and land on the deck of a ship in conditions of ship shaking, big waves, and strong winds. Its operating radius is up to 200km.

To do that, the Ka-28 is equipped with two TV3-117KM turbine engines. Thanks to the "two coaxial propellers" that cancel out the torque that rotates the fuselage, the K-28 can remove the propeller at the tail, allowing the Ka-28 to operate flexibly, especially in cases of sudden movement in many different directions, without being affected by crosswinds.

The Ka-28 is equipped with an electronic system including a reconnaissance radar that can both search and detect underground targets and has interrogation and navigation functions; the VGS-3 submarine sonar device is used to detect submarines and accurately determine the coordinates of submarines.

The Ka-28's anti-submarine equipment also includes magnetic buoys, allowing it to detect targets at a depth of 500m below the surface and up to 10km away. The Ka-28 can conduct underwater reconnaissance operations in rough sea conditions, level 5 waves, with a detection radius of up to 200km.

Ka-28s usually operate in formation, at least two of which, one is tasked with searching, the other receives information and destroys targets.

In terms of weapons, the Ka-28 is equipped with 533 mm homing torpedoes, torpedo missiles (dual-mode), 10 PLAB 250-120 cluster bombs and OMAB bombs. The 533 mm homing torpedoes are placed in a drying compartment to ensure reliability in all weather conditions.

Although this 533 mm torpedo is large in size, its advantage is that it can destroy most types of submarines in the world, including advanced nuclear-powered submarines.
