Can the British government order warships from foreign or Commonwealth shipyards?
Short answerIt may not be absolutely illegal, but peacetime overseas construction would be politically unacceptable and contrary to the domestic industrial purpose of warship procurement.
NotesA categorical legal ban on ordering a British warship overseas is uncertain. In peacetime, however, such a choice would be politically ruinous because naval procurement also serves employment and industrial policy. Commonwealth construction is not treated as a normal exception, although a major war can change what governments accept. The exchange explains why shipyard location becomes part of strategy rather than a simple search for the lowest bid.
