Kolkata: Garden Reach Shipbuilders and Engineers (GRSE) has become the first Indian shipyard to build warships using carbon fibre composite material. The Kolkata-based shipyard has incorporated this technology in its ongoing project of third and fourth ASW (anti-submarine warfare) Corvettes being built for the Indian Navy.
The carbon fibre material, imported from Swedish stockyard Kockumo, is reportedly lighter than stainless steel, which is traditionally used to construct warships. The official added the composite material was used to construct the superstructure of the ship, which would ensure that the vessel is 30 per cent lighter.
In the ASW Corvette, stealth is a key ingredient, said the official, and the composite material would help make it less susceptible to detection. In a record for a ship of her size, the third ASW Corvette has successfully completed Contractor’s sea trials in the first sea sortie itself, while the final machinery trials for the vessel have also been subsequently completed.
It has paved the way for the shipyard to undertake construction of three advanced stealth frigates for the Indian Navy. Recently, the last warship of the four ‘follow on’ water jet fast attack crafts (FACs) built by GRSE was commissioned into the Indian Navy.
The first two ships of the class, INS Tarmugli and INS Tihayu were commissioned in 2016 and are based at Visakhapatnam, while the third ship INS Tillanchang was commissioned earlier this year in March at Karwar.
