The MOD expects to have five of the ships by 2028 (Picture: Babcock).
Defence company Babcock has confirmed it has been awarded a £1.25 billion deal to supply the Ministry of Defence with its fleet of Type 31 frigates.
In September, the owner of the Rosyth dockyard in Fife was named by the Prime Minister as the preferred bidder for the agreement, as part of a step in the Government's plan to increase the number of warships in the Royal Navy over the next 20 years.
The ships will cost an average of £250 million each and will be assembled the Rosyth site, Babcock said.
An MOD spokesperson said: "Today we have signed a contract with Babcock for the Design and Build of five Type 31 general purpose frigates.
"We expect to have the first ship in the water by 2023, with five ships delivered by the end of 2028."
Watch: the First Sea Lord earlier this year on the need for the Type 31s.
More than 2,500 jobs across the UK are expected to be supported as a result of the Type 31 programme, including 150 jobs for new technical apprenticeships.
The vessels will be fitted with the world-leading Sea Ceptor missile system, a range of highly advanced weapon and sensor systems and a combat system with a 4D air and surface surveillance and target indication radar.
They will also have capabilities to operate with a Merlin or Wildcat helicopter.
