VT Group is a privately held United States defence and services company, with its origins in a former British shipbuilding group, previously known as Vosper Thorneycroft. The British part of Vosper Thorneycroft was integrated into Babcock International in the early 2010s and no longer uses the name VT Group. VT Group plc was a British defence and services company, formerly known as Vosper Thornycroft. The Company had diversified from shipbuilding into various engineering and support services, becoming involved in many areas of provision through five main operating groups: VT Communications, VT Education and Skills, VT Services Inc and VT Support Services. VT Group finally exited the Shipbuilding industry in October 2009, after selling its 45% share of the Shipbuilding Joint Venture company BVT Surface Fleet to BAE Systems. Formerly listed on the London Stock Exchange and a constituent of the FTSE 250 Index, the remainder of the firm was acquired by Babcock International Group in July 2010. The company was formed by the merger of two shipbuilding companies Vosper Limited of Portsmouth and J I Thornycroft of Woolston, Southampton in 1966 at which time the Company became listed on the London Stock Exchange as Vosper Thornycroft. Vosper Ltd built small boats and J I Thornycroft had a long history of building destroyers and similar sized craft. The company was nationalised by the Labour Government in 1977, becoming a division of British Shipbuilders. It became a commercial company again after a management buyout in 1985.
