Project-18 Destroyer

MDL is the only Indian shipyard having experience & expertise to build destroyers. At present, MDL is executing the Project 15B Visakhapatnam-class destroyers which will complete by the year 2024. MDL has also started discussion with Indian Navy on Next Generation Destroyer(NGD). During its investor call of Q1 FY23, the firm has informed that a total of 8 NGDs will be build under two phases. The entire project is estimated to worth $10 Billion. MDL is procuring a new floating dry dock to accommodate the massive 10,000 tonnes Next Generation Destroyers (NGD).

DRDO’s long range multifunction radar (LRMFR)

The most noticeable change in the Project-18 class destroyers is going to be their radars. In almost all latest naval warships, we can see Israel’s MFSTAR mast-mounted radar. This will be likely to be replaced with DRDO’s long range multifunction radar (LRMFR).

INS Anvesh, a technology demonstration vessel (TDV) being built for DRDO at Cochin Shipyard Limited (CSL) has been fitted with a housing for a new type of dual-panel long-range radar system by LRDE called Long-Range Multi-Function Radar (LRMFR). It is an active phased array radar with a range more than 500 km & features octagonal faceplates that are approximately 5.5–6 m in diameter. Therefore, instead of mast mount radar, NGD may feature a multi-faced Active Phased Array Radar (APAR) based on LRMFR. The NGD will require 2 types of main APAR radars – one for shorter-wavelength & another one for longer-wavelength. LRMFR will perform the role of target tracking to fire control for SAMs/BMD. The NGD will feature HUMSA-NG - a third generation ship borne, hull mounted, Sonar system developed by DRDO and productionised by BEL.

NGD Weapons & fire

The Next Generation Destroyer will be built to fire the arrays of indigenous weapons for anti-surface, anti-submarine and land attack roles. With 128 VLS, the warship will have massive fire power. The key weapons of the destroyer will be BrahMos Missile, BrahMos-NG, LRSAM-ER, Nirbhay/ITCM LACM, MRSAM, XRSAM & VL-SRSAM & AAD. The destroyer will also be equipped with lighter version of SMART ASW missiles for taking on enemy submarines & Advance Torpedo Decoy system. The missile has a range of 643 km (400 mi) carrying a lightweight torpedo of range 20 km (12.5 mi) with 50 kg high explosive warhead. The 533mm Varunastra (or some future version of it) is likely to be the main torpedo armament. NGD may also feature a UVLS (Universal VLS) which will eliminate the need of multiple missile launchers. It will feature a 127mm main Naval gun and three 76mm Super Rapid guns.
