The '''Lanchester''' is a [[submachine gun]] ("machine carbine") manufactured by the [[Sterling Armaments Company]] between 1941 and 1945. It is an evolution from [[MP 18#Evolution|MP28/II]] and was manufactured in two versions, Mk.1 and Mk.1*; the latter was a simplified version of the original Mk.1, with no fire selector and simplified sights. It was primarily used by the [[Royal Navy during the Second World War]], and to a lesser extent by the [[Royal Air Force Regiment]] (for airfield protection). It was given the general designation of Lanchester after [[George Lanchester]], who was charged with producing the weapon at the Sterling Armaments Company.
