An expected £619 million will go to Cammel Laird in Birkenhead to support RFA tankers.
A&P in Falmouth has been awarded £239 million to support the RFA’s Bay class landing ships, as well as RFA Argus and HMS Scott.
A further £150 million is expected to go to UK Docks in Tyneside to support two survey ships and a ice patrol vessel HMS Protector.
Defence Minister Stuart Andrew said: "This £1bn deal secures work for some of our world-leading shipyards into the next decade, supporting over 700 jobs for workers to ensure our ships remain at sea to defend the nation.
"This vital work is not only great news for our Navy, but also underlines the importance of defence to our national skills and prosperity."
The Ministry of Defence say the deal is expected to deliver savings worth more than £100 million for defence.
