Vickers Limited was a British engineering conglomerate. The business began in Sheffield in 1828 as a steel foundry and became known for its church bells, going on to make shafts and propellers for ships, armour plate and then artillery. Entire large ships, cars, tanks and torpedoes followed. Airships and aircraft were added, and Vickers jet airliners were to remain in production until 1965.

Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metropolitan-Vickers F.2. Its factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world.
