Alvis Ltd. was created when United Scientific Holdings plc acquired the Alvis division of the nationalised vehicle manufacturer British Leyland in 1981. United Scientific maintained its own name until 1992 when the group was renamed Alvis plc. Alvis acquired Swedish armoured vehicle manufacturer Hagglunds AB in 1997 and the armoured vehicle business of GKN in 1998. Finally, it acquired Vickers Defence Systems from Rolls-Royce in October 2002. Alvis was acquired by BAE Systems in 2004 and became BAE Systems Land Systems (Weapons & Vehicles), now part of the BAE Systems Land and Armaments operating group.
