The 2-pounder "pom-pom" was widely used on British
warships until replaced by the Bofors. It was a
water-cooled belt-fed weapon with a good sustained rate of fire,
further enhanced by its use in quadruple or even eight-barrelled
mountings. However, its muzzle velocity compared unfavorably with the 40mm Bofors.
