Kavach is an anti-missile naval decoy system to distract radar-guided missiles from their targets and act as a system for self-defence. It was designed and developed by the Ordnance Factory Board for the Indian Navy.
The Indian Navy previously procured chaff rocket systems from the Soviet Union. Supplies came to a halt following the dissolution of the Soviet Union in the early 1990s. The Ordnance Factory Board (OFB) took up the challenge to design and develop a chaff rocket system to achieve self-reliance in this field.[1] [2] OFB Director General and Chairman, D.M. Gupta, stated in May 2011 that the company had created two prototypes, successfully conducted the first trial, and would conduct a second and final trial later that year before the system was inducted into the Navy.[3]
The Kavach decoy system releases chaff made up of silver coated glass fiber. The chaff forms a clutter which remains suspended in the air, causing the incoming radar-guided missile to mistake the chaff for the actual target, and get locked onto the chaff instead of the actual target. Each Kavach rocket costs around –.
The Kavach system has chaff rockets of three different versions based on the range:[2]
These versions are fired in different situations based on incoming threats.
The Kavach Mod II is a three-layered "soft-kill" system. The launch tube configuration is 4×4 launch tube in two variants: Long-Range and Short-Range. The LR and SR variant weighs 1680 kg and 1350 kg, has a height of 269 cm and 246 cm, and bore of barrel measurement of 106 mm and 98.4 mm, respectively. Length and width of both the systems measures 1300 mm each. According to official sources, 9 such systems are installed on Kolkata-class, Kamorta-class and Deepak-class naval ships.[4] It has a rotation speed of 60° per second. The Fire Control System (FCS) for the Kavach Mod II includes a Main Fire Control System (MFCS), 4 Launcher Control Unit (LCU) and a Remote Fire Control System (RMFCS). It can detect, track and engage upto 5 threats.[5]
There are different operational modes
The first batch of Kavach rockets were formally handed over to the Navy on 25 May 2012 by the Ammunition Factory Khadki (AFK), Pune which manufactures the rockets. The Kavach MOD II multi-barrel rocket launchers are manufactured by the Machine Tool Prototype Factory (MTPF), Mumbai of Armoured Vehicles Nigam Limited.[6] [7] The Fire Control System (FCS) is manufactured by Bharat Electronics Limited (BEL).
AFK was contracted to deliver around 4,000 Kavach variants to the Indian Navy by 2015.[8]
The first ship to be equipped with Kavach was the anti-submarine corvette INS Kamorta (P28).[9] Ship classes fitted with Kavach include:
