Hull from of this craft is same as that of PNS LARKANA, the design of which has been based on an earlier sea proven vessel. The initial calculations of resistance/powering and ship's motion/sea keeping etc. were verified through model testing in a 40 x 30 feet water tank and 1/15 size of ship's model. Ordinates of various sections were then drawn to make a full scale lines plan of the ship at PN Dockyard. These lines were carefully faired in all three views through traditional Naval Architectural skills before making wooden templates for frame bending & subsequent construction of the craft.
It is an all welded steel construction with Aluminium superstructure of reduced radar cross section. To keep the weight low, some internal bulkheads have also been made of composite material. The structure has been specially strengthened to sustain the shock loading of missile & gun fire.
Equipped with state of the art machinery and equipment. Most of the navigational and communication sensors are of West European origin. Special light weight MTU diesel engines provide the ship a thrust of 2800 HP to each of its two shafts. Fitted with C-802 surface to surface sea skimming missile of over 100 KM range. The 37 mm twin barrel naval gun, the ESM and the 4 decoy launchers provide the craft an adequate defence against air attacks. The entire weapon system is integrated with central command information and control system. To support the weapon system, the ship will also be fitted with link Y data link, in addition to its own surveillance and search radar.
Two Caterpillar Diesel Generators of 165 KW each provide different power supplies to equipment of the ship through a 32 KM long cable network of nearly 17000 end connections. The ship has a central air-conditioning system throughout the ship's living and operating spaces. Special care has there ship being rather small for the equipment outfit, all living and operating spaces are quite congested. Special care has therefore been taken to make life onboard more comfortable through better living/environmental conditions.
The ship took nearly two years for completion including the harbour and sea acceptance trails. Being the first ship of its kind, many things squeezed towards the end due to various foreseen & unforeseen problems. The real tough phase was during the massive outfitting work including installation of machinery/equipment, piping/ducting, cabling/cable connections, insulation/painting and furnishing/finishing etc which was completed in the short span of 07 months available between the time after launching on 16 November 1996 and commencement of harbour trials on 16 June 1997.
