The IRS-class ACTCM barge is a series of 19 ammunition barge being built for the Indian Navy by two MSME shipyards. Under the project, 11 Ammunition Cum Torpedo Cum Missile (ACTCM) barges are being built by Suryadipta Projects Pvt Ltd of Thane, Maharashtra while 8 Missile Cum Ammunition (MCA) barges are being built by SECON Engineering Projects Pvt Ltd of Visakhapatnam, Andhra Pradesh. The contracts with the shipyards were signed on 5 March 2021 and 19 February 2021, respectively.[1][2][3] The barges are either based at INS Tunir, Naval Missile Depot at Mumbai, or Naval Ammunition Depot (NAD), Karanja at Naval Dockyard (Mumbai) {ND(Mbi)}.
IRS-class Ammunition-Cum-Torpedo-Cum-Missile (ACTCM) barge are to be inducted in the Indian Navy to undertake the mission needs for transport, embarking or disembarking of ammunition, torpedo, missile, articles, etc. on the IN ships, thereby providing impetus to operational commitments of the navy both alongside jetties and outer harbors boosting operational readiness and effectiveness. The ACTCM barges are also referred to MCA (Missile Cum Ammunition) barges, but all are designated as Large Scale Additive Manufacturing (LSAM).[6] All major and auxiliary equipment/systems on the barge, which is set to have a service life of 30 years have been sourced from indigenous manufacturers.[7]
Delivery of the first barge LSAM 15 (Yard 125) by Suryadipta Projects to Indian Navy was done on 9 June 2023.[8] LSAM 7 to 14 has been built by SECON Engineering and LSAM 15 to 25 has been built by Suryadipta Projects.[9][10] The barge has a cargo hold of 100 tonnes. The barge has ample facilities for fire fighting, power generation, and crew accommodation.[11][12][2]
As of September 2025, all 8 of the MCA barges have been delivered and inducted while 10 of the 11 ACTCM barges have been delivered and inducted in to service.[13][14] The last of the barges by Suryadipta Projects was launched on 9 September 2025 after a gap of 6 months..[15]
