Fighting module 3S87 SPAR 3M87 "Dirk" (Kashtan — air defence gun / missile system (booklet). Rosoboronexport. 2000s).
SPAR project "Dirk" got its start in the late 70s. This development was carried out in the interests of the Navy. Zarqa "Dirk" was due to change outdated mounts AK-630. Changing the features of surface ships armed clashes with the forces of the enemy in speed, the distance and the height of the attacker's influence led to the need not just to change mounts AK-630, and to katigorichnye configuration in the principles of building a system of defensive fire. Increased attention was paid to protect against low-flying targets and speed of air attack, the attackers ship from different directions and heights.
Initially, the fate of the "Dirk" was not very funny. To simplify the substitution of the AK-630 were standardized mounting portions. But on weight and size traits "Dirk" could not be installed on many types of vehicles. To the credit of our gunsmiths situation was correct. New complex received the lowest weight and lowest overall height, which have allowed to establish Zarqa on ships with a displacement of 400-500 tons. The complex is now more known as Chestnut M (M — mean sea).

The unique design is to combine the 2 kinds weapon: rocket and artillery. It would seem that for what? But the ideology of the complex is striking in its simplicity, that is, genius.
The main instrument of Zarqa Chestnut M missile launchers are. The complex is in the firing position has in store of 32 missiles 9M311M or 9M311-1. . Anti-aircraft operated rocket a two-stage solid-fuel missile, equipped with a fragmentation warhead core and non-contact sensor target. Rocket comes in the transport and launch container, allowing recharging 8 rockets for one minute.
Artillery weapons firing module consists of a 2-artblokov with anti-aircraft guns (AO-18 / 6K30GSH / GS-6-30K) 30 mm caliber with a combined rate of fire of 10 thousand rounds per minute.
Missile and artillery components are combined into a single combat module (BM). Vessel according to the rank and displacement of such plants may be arranged from one to six. In the most complete set of BM are located on the sides of the circle to cover all motivated zones.

As today's clashes characterized by the highest transience, a person is not able to have time to assess the situation and decide to kill the target. And if the goal is not one? To control Zarqa Chestnut M has developed a unique system of management. The guidance system of armament consists of a 2-channel high-precision control — radar and television combined into a single, integrated system with elements of artificial intelligence. The complex is at once captures and accompanies goal by radar and thermal imaging optical system. This allows you to see the enemy in any weather, and more precisely determine the coordinates of the approaching enemy missiles.
Complex method looks something like this. The command module constantly keeps under control the air space around the ship. The ships on which there is system assessment of air situation, the command module Zarkov gets from her preparatory information and produces dopoisk goals, preparation and transmission of their target indications BM. The control system can recognize at once to 6 goals. The objectives can be both 6-foot Tomahawks and a half — two-meter ATGM. After rassredotachivaniya purposes largest BM start to run only one missile. The missile is controlled by radio command band communications. For 5 yards to the goal on a rocket fires proximity fuze and warhead explosion released a huge amount of iron rods 600 mm long. Fly rods in a circle with a diameter of 5 meters and hit the target. If the lesion does not work out, and you remember that all the action from the moment of discovery until the lesion occurs within about 30 seconds, is effective artillery unit of the system. Receiving instructions from the control system of the impending approach goals, BM enacts anti-aircraft guns. They hit the target at a height of 2 m to 3 km. If you own a huge rate of accumulation of anti-aircraft machines produce 30-mm shells from which to dodge is simply unrealistic. Carried dostrel purpose.

Specialists Tula KBP convinced that Chestnut great future. After all, it can be upgraded further. On trying to install a new set of rocket launchers, which can hit targets at a distance of 20 km. This is approximately two times more than presently. It is also contemplated that Chestnut will produce the same target at once 2 missiles. This approach translates Chestnut from a defensive to an offensive set. This will allow Chestnut work and on land.
