The weapon can fire at 500-600 rounds per minute and has a range of up to 2,000m. The half inch/12.7mm diameter shells can penetrate light armour and will tear through plastics, such as RIB speed boats.

HMS Lancaster close-range weapons instructor leading seaman Mikey Benbow said: “I was eager to get on the mount as nobody on the ship had ever fired it before and although it’s within the confines of my job on board, it’s a new weapon to me and has given me another challenge and weapon to train with.

“When it actually came to firing, to be honest it didn’t have as much of a kick as I thought it would, but it really came into its own with the sound of each round leaving the gun.
