Indonesian state-owned shipbuilder PT PAL held a steel-cutting ceremony for the Indonesian Navy's (Tentara Nasional Indonesia-Angkatan Laut's/TNI-AL's) second SIGMA 10514 Perusak Kawal Rudal (PKR) guided-missile frigate in Surabaya, Indonesia, on 17 September.

The vessel is being built jointly with Dutch shipbuilder Damen Schelde Naval Shipbuilding (DSNS) under a contract signed in 2013 by the Indonesian Ministry of Defence. The contract follows a prior tender, signed in June 2012, to construct the first ship.

Both frigates are being assembled from six major block modules in an arrangement aimed at transferring naval shipbuilding expertise from DSNS to PT PAL. In the first vessel, four modules were built by PT PAL and two supplied by DSNS.

Damen Schelde Naval Shipbuilding has developed its vision on mission modularity and has created the unique SIGMA Multi Mission Bay. The SIGMA Multi Mission Bay is designed to fulfil the need for flexibility in naval defence through Mission Modularity.

It provides operational flexibility and increased availability in corvette size ship design. Enabling easy exchange of specific mission modules through life, it also increases future growth potential, while reducing cost of modernizations.

The covert area of the SIGMA Multi Mission Bay ©, at the stern of the SIGMA class vessels, offers flexibility to support various missions within one single class of ships, ranging from Humanitarian Aid, Special Forces Support, Anti Submarine Warfare, Mine Counter Measure Operations to Mine Laying capabilities. Making the SIGMA Multi Mission Bay © the true force multiplier for the highly successful SIGMA platform.
