brand their products under their former names. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage & Wagon. Nationalisation In 1960, the aircraft interests were merged with those of the Bristol, English Electric and Hunting Aircraft to form the British Aircraft Corporation (BAC). This was owned by Vickers, English Electric and Bristol (holding 40%, 40% and 20% respectively). BAC in turn owned 70% of Hunting. The Supermarine operation was closed in 1963 and the Vickers name for aircraft was dropped in 1965. Under the terms of the Aircraft and Shipbuilding Industries Act BAC was nationalised in 1977 to become part of British Aerospace, which exists today in the guise of BAE Systems. The Aircraft and Shipbuilding Industries Act also led to the nationalisation of Vickers' shipbuilding division as part of British Shipbuilders. These had been renamed Vickers Armstrong Shipbuilders in 1955, changing again to Vickers Limited Shipbuilding Group in 1968. This division was privatised as Vickers Shipbuilding & Engineering in 1986, later part of GEC's Marconi Marine. It remains in operation to this day as BAE Systems Submarines. Vickers plc With their steelworking operations also nationalised into British Steel Corporation the remnants of Vickers became Vickers plc. In 1986, Vickers acquired the armaments manufacturer Royal Ordnance Factory, Leeds, which became Vickers Defence Systems. Other acquisitions included automotive engineers Cosworth in 1990, waterjet manufacturer Kamewa in 1986 and Norwegian marine propulsion and engineering company Ulstein in 1998. 1998 also saw the sale of Rolls-Royce Motors and Cosworth to Volkswagen Group for £430 million, beating out BMW's offer of £340 million. Current status of Vickers In 1927, Vickers merged with the Tyneside-based engineering firm Armstrong Whitworth to form Vickers-Armstrongs. Armstrong Whitworth developed in a similar way to Vickers, expanding into various military fields and became famous for its artillery construction at Elswick and shipbuilding at its yard at High Walker upon Tyne. In 1928, the Aviation Department changed its name to Vickers (Aviation) Ltd and shortly afterwards acquired Supermarine, which became 'Supermarine Aviation Works (Vickers) Ltd'. In 1938, the two companies were reorganised as Vickers-Armstrongs (Aircraft) Ltd, although the former Supermarine and Vickers works continued to brand their products under their former names. In 1929, the acquired railway business was merged with that of Cammell Laird to form Metropolitan Cammell Carriage & Wagon. 1.6 Fifth change of the company After the Second
