The Badr class is a class of corvette built by the United States and operated by the Saudi Navy. The class has been relegated to a coastal defence role following the modernisation of the Saudi fleet. There are four vessels in service; Badr, Al Yarmook, Hitteen and Tabuk.


In January 1972, Saudi Arabia signed an agreement with the United States to set up a 10-year programme to greatly enlarge the Saudi Navy, previously a small coastal patrol force. The programme envisaged the construction in the United States of a series of corvettes as well as other warships such as minesweepers and amphibious warfare ships.[1][2] As part of this programme, on 30 August 1977, an order was placed with the Tacoma Boatbuilding Company of Tacoma, Washington for 4 missile-armed corvettes, with delivery expected between 1980 and 1981.[2][3]

The four ships, at first known by the US-Navy style designation of "PCG", and later as the Badr-class, are 74.68 metres (245 ft 0 in) long overall, with a beam of 9.60 metres (31 ft 6 in) and a draught of 2.59 metres (8 ft 6 in).[4] Displacement was intended as 720 long tons (730 t),[2] but the ships were completed significantly overweight, and were recorded as displacing 903 long tons (917 t) standard and 1,038 long tons (1,055 t) full load in 1995.[3] They are powered by one General Electric LM2500 gas turbine rated at 23,000 shaft horsepower (17,000 kW) and two MTU 12V625 TB91 diesel engines (rated at a total of 3,058 brake horsepower (2,280 kW)) in a Combined Diesel and Gas (CODAG) arrangement, driving two controllable pitch propellers. This gives a maximum speed of 30 knots (35 mph; 56 km/h) when using the gas turbine and 21 knots (24 mph; 39 km/h) on the diesels. The ships have a range of 4,000 nautical miles (4,600 mi; 7,400 km) at 20 knots (23 mph; 37 km/h).[4]

Principal anti-ship armament consists of eight Harpoon anti-ship missiles, with a gun armament of a single OTO Melara 76 mm gun forward, one Vulcan Phalanx close-in weapon system (CIWS) aft, two Oerlikon 20 mm cannon, an 81 mm mortar, and two 40 mm Mk 19 grenade launchers. Anti-submarine armament consisted of two triple Mark 32 Surface Vessel Torpedo Tubes for Mark 46 torpedoes. SPS-40B air search radar and SPS-55 navigation/surface search radars are carried, while a Mark 92 fire control radar is fitted above the ship's bridges. SQS-56 hull mounted sonar is carried to direct the ships' torpedo tubes.[4]
