Development and design
Main article: Commandant Rivière-class frigate

The main gun armament of the Commandant Rivière class consisted of three of the new French 100 mm (4 in) guns, with a single turret located forward and two turrets aft.[1][2] These water-cooled automatic dual-purpose guns could fire a 13.5 kg (30 lb) shell at an effective range of 12,000 m (39,000 ft) against surface targets and 6,000 m (20,000 ft) against aircraft at a rate of 60 rounds per minute.[3] A quadruple 305 mm anti-submarine mortar was fitted in 'B' position, aft of the forward gun and in front of the ship's superstructure,[1] capable of firing a 230 kg (510 lb) depth charge to 3,000 m (9,800 ft) or in the shore bombardment role, a 100 kg (220 lb) projectile to 6,000 m (20,000 ft).[4] Two triple torpedo tubes were fitted for anti-submarine torpedoes, while the ship's armament was completed by two 30 mm Hotchkiss HS-30 cannon.[1] The ships had accommodation for an 80-man commando detachment with two fast landing boats, each capable of landing 25 men.[5]

Construction and career

Commandant Rivière was laid down in April 1957 and launched on 11 October 1958 at Arsenal de Lorient in Lorient. The vessel was commissioned on 4 December 1962.

In 1984–1985, Commandant Rivière was converted to a sonar-trials ship. The ship's armament was replaced by a single 40 mm Bofors gun and two 12.7 mm machine guns, while the ship's stern was rebuilt to accommodate a hoist for a variable depth sonar, which was used to test various active and passive towed array sonars.[5][6]

She serve as a breakwater in Saint-Mandrier from 1993 to 2009 after decommissioning in 1992. She awaited dismantling in Toulon from 2009 to 2014 and dismantled in Ghent in 2015.
