IRS is proud to participate in the move towards increased “Atmanirbhar” (Self Reliance) in the Defence Industry, announced by the Government of India. IRS provides a full range of Classification and Certification services to Shipyards constructing ships and craft for the Indian Navy, Indian Coast Guard and other Defence and Paramilitary Services, and to the Industries supplying materials, machinery and equipment for these vessels. Several of these vessels are also maintained in IR Class after delivery.

More than 300 vessels and numerous boats have already been built under IRS Classification for the Indian Navy, Indian Coast Guard, Border Security Force, National Disaster Relief Force and other Government agencies.

IRS is also certifying machinery and equipment. sourced by shipyards from leading overseas manufacturers, ensuring that the products meet the specific requirements of the shipyards and shipowners.

Advanced Technical Studies and Analyses are also being carried out by qualified and experienced personnel for verifying specific design requirements, including strength, vibration, stability and for minimising acoustic, magnetic, infrared and radar signatures.
