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; {{ship|Saudi corvette|Badr|612|2}}, {{ship|Saudi corvette|Al Yarmook|614|2}}, {{ship|Saudi corvette|Hitteen|616|2}} and {{ship|Saudi corvette|Tabuk|618|2}}.
==Design== 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.<ref name="conways95p327">{{Harvnb|Gardiner|Chumbley|1995|p=327}}</ref><ref name="jfs79p420">{{Harvnb|Moore|1979|p=420}}</ref> 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.<ref name="jfs79p420"/><ref name="conways95p329">{{Harvnb|Gardiner|Chumbley|1995|p=329}}</ref>
The four ships, at first known by the US-Navy style designation of "PCG", and later as the ''Badr''-class, are {{convert|74.68|m|ftin}} long overall, with a beam of {{convert|9.60|m|ftin}} and a draught of {{convert|2.59|m|ftin}}.<ref name="cf98p769">{{Harvnb|Baker|1998|p=769}}</ref> Displacement was intended as {{convert|720|LT|t}},<ref name="jfs79p420"/> but the ships were completed significantly overweight, and were recorded as displacing {{convert|903|LT|t}} standard and {{convert|1038|LT|t}} full load in 1995.<ref name="conways95p329"/> They are powered by one General Electric LM2500 gas turbine rated at {{convert|23000|shp|kW}} and two MTU 12V625 TB91 diesel engines (rated at a total of {{convert|3058|bhp|kW}}) in a Combined Diesel and Gas (CODAG) arrangement, driving two controllable pitch propellers. This gives a maximum speed of {{convert|30|kn|mph km/h}} when using the gas turbine and {{convert|21|kn|mph km/h}} on diesel. The ships have a range of {{convert|4000|nmi|mi km}} at {{convert|20|kn|mph km/h}}.<ref name="cf98p769"/>
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.<ref name="cf98p769"/>
