The Kashtan-М shipborne air defence gun/missile system is designed for protection against anti-ship missiles, anti-radar missiles, guided aerial bombs, aircraft, helicopters as well as for engagement of small-displacement vessels and small-size sea and ground targets.
- combat module;
- surface-to-air missiles;
- command and control module;
- ground support equipment.
The command and control module serves to detect and classify aerial (including low-flying) and stationary targets, to track, to distribute and to designate them to combat modules.
The combat module consists of a gun/ missile unit, radar and optical fire control system, computer system.
Normally, the ship can be armed with one to six combat modules depending on its displacement and self-defence capability required.
9M311-1 two-stage solid-propellant SAM features a fragmentation rod warhead with a proximity fuse. Missiles are housed in transport-launch containers ensuring their safe handling and reliability.
The gun mount comprises two 30mm six-barrel GSh-6-30K rapid-fire cannons with a linkless ammunition feed and evaporative cooling system.
The integrated control system simultaneously tracks targets and guides one or two missiles onto them via its radar and TV/optical channels with autonomic selection of optimal mode.
To work in adverse weather conditions Kashtan-М is equipped with a termal imaging system.
Kashtan-M ADGMS also comprises a below-deck storage/loading system (capacity – 32 or 48 SAMs, four-missile launch unit is loaded within 1.5 min).
Kashtan-M system ensures efficient self-defence of the carrier-ship thanks to high probability of interception of approaching air targets at longer distances (10,000 m to 1,500 m) with missiles, and a follow-on engagement of survived targets at a close-in range (4,000 m to 500 m) with gunfire.
Fully automated combat operation of the system (from target acquisition till engagement) allows it to engage up to five targets a minute. Kashtan-M ADGMS can be installed on ships displacing 400-plus tonnes.
