The merger of Marconi Electronic Systems (MES) and British Aerospace formed BAE Systems. The combined shipbuilding capability was contained in the wholly owned subsidiary BAE Systems Marine Ltd that had the capability to manufacture a full range of surface ships and submarines.

In 2003, the surface ship and submarine units split into BAE Systems Naval Ships and BAE Systems Submarines respectively.
