The UK Ministry of Defence (MoD) has awarded contracts worth £3.2bn to support the management of British naval bases and the maintenance and overhaul of the Royal Navy's fleet of 56 warships and submarines.
UK defence secretary Michael Fallon said: "This huge investment in our naval bases will directly sustain more than 7,500 jobs and skills across the UK, and ensure that the Royal Navy's fleet of 56 warships and submarines are in the best possible condition and available for operations."
"Following the £3.5bn Scout armoured vehicle contract, this is the second biggest defence contract placed by this government and reflects our commitment to giving our armed forces what they need to keep Britain safe.
"As a former Minister for Portsmouth I know how important naval bases are for the local economies, so I am delighted that these contracts have been awarded."
Babcock, which oversees naval bases at Devonport and Clyde, secured a major share by winning a contract worth £2.6bn, while BAE Systems, which manages Portsmouth Naval Base, signed a £600m contract.
Royal Navy professional head and chairman of the Navy Board admiral Sir George Zambellas said: "These significant contracts represent a strategic investment in the Royal Navy's essential infrastructure.
"Without the stalwart and tireless support provided by each of the three naval bases ashore, the ships and submarines of the Royal Navy would not be able to deploy as a credible, strategic and global presence at sea."
The navy has recently decommissioned its last Invincible-class aircraft carrier, HMS Illustrious, after it registered 900,000 miles on operations in its 32-year service.
