General info

RUR-4 antisubmarine rocket

Mark 108 Weapon alfa shoots RUR-4 320 mm antisubmarine rockets. Explosive mass of 113 kg of TNT and penetration of 99 mm makes it very effective against boats and ships. Biggest disadvantages are a range of 800 meters and a speed of 306 km/h which makes it very situational for naval combat.

History

During World War II, The United States Navy worked to attempt to counter the Type XXI U-Boat and decided to develop a similar to the 7.2 in Mousetrap but more powerful weapon to counter the new submarine. The design started with a crash program at Naval Ordinance Test Station China Lake in California where they designed a rocket intended to fire in front of the ship to sink the enemy submarines. Even when the war ended, the development of the weapon nicknamed "Weapon Able" continued until it was finished in 1949. With the foundation of NATO, the weapon was re-designated to the Mark 108 "Weapon Alfa" to fit the NATO Phonetic Alphabet later in its career.

The Mark 108 Weapon Alfa launcher fires a 500-pound 5-inch rocket 250-pound warhead that sinks at a rate of 40 feet per second and a range of 400 to 800 yards and a time fuze set by an SQG-1 sonar. Two mounts were developed for the Weapon Alfa launcher. The first was a modified version of the Bofors L/60 Mark 1 mount weighing 22,760 pounds and a later purpose-built mounting 25,240 pounds. The Mark 108 Weapon Alfa was primarily mounted on post-war destroyers from the 1950s and 1960s such as the Mitscher-class. In 1963, the Mark 108 launcher was re-designated again as the RUR-4 Weapon Alfa and with the RUR-5 ASROC (Anti-Submarine ROCket) entering service in 1961, the Weapon Alfa was phased out by the end of the decade. The Japanese Maritime Self-Defense Force also adopted the Mark 108 using it on their anti-submarine warfare craft such as the Isuzu frigate.
