Close-in Weapon System or CIWS is the last line of defence against any aerial threat. Since this gun is last line of defence, the time to respond to the threat is very less. The gun needs to be highly agile with very high rate of fire to ensure higher hit probability. The two prominent names in the CIWS among world Navies are : Raython (Phalanx CIWS) and Rosoboronexport (AK 630 CIWS or Kashtan CIWS). The CIWS widely used by Indian Navy in its warship is AK 630.

AK 630 CIWS or Kashtan CIWS

The guns used in the Kashtan are the GSh-30K six-barrel 30 mm rotary cannon. The GSh-30K has a higher rate of fire compared to other guns used by other CIWS such as the GAU-8 on the Goalkeeper and the M61 Vulcan on the Phalanx. It can fire off over 10,000 rounds per minute. The missiles used in the Kashtan are the 9M311 missiles. In combat mode, the gun mount operation is fully automated, except for the belt filling and loading operations. The weapon is a modular system consisting of a command module and typically two combat modules.

The command module detects and tracks threats, distributes targeting data to the combat modules, and interrogates IFF of approaching threats. The command module has a 3-D target detection radar, and an all weather multi-band integrated control system. Depending on the number of installed combat modules, the system can engage multiple targets simultaneously. The combat modules automatically track using either radar, electro-optronic control system (such as FLIRs) or both, and then engages targets with missiles and guns. The combat modules are typically equipped with two GSh-30K (AO-18K) six-barrel 30 mm rotary cannons, fed by a link-less feeding mechanism, and two 9M311-1 missile launchers equipped with 4 ready-to-fire missiles each and fed by a reloading system storing 32 missiles in ready-to-launch containers.

ARDE Gatling Air Defence gun

In past, DRDO has initiated the development of a Multi-barrel, Gatling Gun with ROF of 4200 rpm. The Army wanted two types of AD guns. One with weight around 1000 – 1500 Kg and other weighing 4000–5000 Kg with ROF 1000– 2000 rounds in each case. However, the Gatling gun of DRDO did not meet the user requirement & the project was foreclosed in October 1995.

The DRDO’s lab ARDE seems to have re-initiated the development of an indigenous multi-purpose gatling gun which can be used in warships or land based platforms. The gun is being developed considering the latest and future threat assessment and will incorporate new technologies such as AI based target engagement and damage assessment post firing. The gun will be Digitally operated with all electric drive & actuation. The target tracking will involve radar as well as EO/IR sensors.

The system will have 360 degree Revolving Slip-ring based Gun mount. It will feature ruggedized, Digitally Operated, Embedded Electronics, Power Electronics, Controllers, Sensors, Drivers, Thermal Management and Sensor to Shooter Logic. The gun will feature advance stealth features which will include: Camouflage, Concealment, firing signature management, Detection Avoidance and Stealth operation.

It will be using Combustible cartridge & proximity/programmable fuze based ammo.
