PT PAL has launched the first of two Sigma 10514 Perusak Kawal Rudal (PKR) guided-missile frigates designated for the Indonesian Navy (TNI AL).
PT PAL built these ships in collaboration with Damen Schelde Naval Shipbuilding (DSNS).
Sigma 10514 PKR
The Sigma 10514 PKR frigate was a project initiated in August 2010 by the Indonesian Ministry of Defence. The Ministry awarded a contract to Damen for the construction of the first Sigma 10514 PKR in December of that year. The first steel was cut in January 2014 and the keel was laid in April 2014 at PT PAL shipyard in Surabaya. The PKRs are designed and built to endure various missions.
Primarily, the vessel will be operated for Anti-Air Warfare, Anti-Surface Warfare, and Anti-submarine Warfare. However, it is also compatible with Maritime Security, Search and Rescue, Patrol, and Humanitarian Support tasks.
Modular Construction
The Sigma 10514 PKR has a proven design and is built using a modular approach. Sigma stands for Ship Integrated Geometrical Modularity Approach. In essence, the PKRs are divided into six modules of which four were built in PT PAL’s shipyards while the other two were built and tested at DSNS in the Netherlands. The modular construction enables greater flexibility, is more cost effective and allows for building in various locations worldwide. When the six modules were complete, PT PAL had the responsibility of integrating them into one vessel.
Main Characteristics
Technically, the PKR has a length of 105.11 metres, a beam of 14.2 metres and a displacement of 2365 tons. The vessel features a fully air-conditioned accommodation for up to 122 persons. The helicopter deck is suitable to host a medium sized helicopter hanger with a weight of max 10 tons. The vessel is equipped with two rigid hull inflatable boats (RHIBs) for rescue and patrol operations. The frigate has a speed of 28 knots, and can sail up to 5000 nm at 14 knots. The endurance is at least twenty days at sea.
PKR Propulsion System
The propulsion system of the PKR vessel utilises a combined diesel or electric (CODOE) which consists of two 10,000 kW maximum continuous rating (MCR) diesel engines, two 1,300 kW electric motors, two double input gearboxes and two 3.65 metre controllable pitch propellers.
The vessel is equipped with a sophisticated platform management system that enables operating, control and monitoring of the ship’s auxiliary systems. The vessel will be equipped with a complete, state-of-the-art sensor and weapon package to counter air, surface and sub-surface threats. For self-defence, the vessel is equipped with comprehensive electronic warfare systems.
The sensory aspect of the Sigma is equipped with 3D surveillance radar with a range of 250 km. There is also a target indication radar which has an electro optical fire control system. The sensor array comprises a Friend or Foe Identification (IFF) system and a hull mounted sonar as well.
