Methil's Harland and Wolff workers will be making components for three new Royal Navy support ships.
The Belfast firm, within British-led Resolute, have been made the preferred bidders by the Ministry of Defence, to deliver the ships to the Royal Fleet Auxiliary.
Resolute also includes BMT and Navantia UK.
Team Resolute will get a £1.6 billion contract (before inflation) to manufacture the vessels providing munitions, stores and provisions to the Royal Navy’s aircraft carriers, destroyers and frigates deployed at sea, subject to HM Treasury and Ministerial approval.
The entire final assembly for all three ships will be completed at Harland & Wolff’s shipyard in the Northern Irish capital.
Ben Wallace, the Defence Secretary, said: "This is a welcome boost to the UK shipbuilding industry.
"By selecting Team Resolute, the Ministry of Defence has secured £77 million of investment into UK shipyards, creating around 2,000 UK jobs, and showcasing cutting-edge British design.
"Building on ambitions laid out in the National Shipbuilding Strategy, we are also bolstering technology transfer and key skills from a world-renowned shipbuilder, crucial in the modernisation of British shipyards."
On behalf of Team Resolute, Harland & Wolff's Group CEO, John Wood, said: "Team Resolute is proud to have been selected as preferred bidder to provide the Royal Fleet Auxiliary with three state-of-the-art, adaptable ships which will fulfil the Royal Navy’s needs while strengthening UK sovereign design and shipbuilding capability, as well as generating around £1.4 billion in national social and economic value.
"Team Resolute will be making a significant investment into the UK and help to level up UK Government defence spend across the whole Union.
"We will create high quality UK jobs, apprenticeships and four facilities across the UK which will have shipbuilding capabilities fit for the 21st century."
DE&S Director General Ships Vice Admiral Paul Marshall said: "FSS will deliver worldwide logistic and operational support to the Royal Navy, including the Maritime Strike Group on deployment.
"Significant investment in emerging shipyards across the UK will also strengthen and diversify our industrial base.
"Alongside our investment in the Type 26 and Type 31 frigate programmes, this breadth will be vital to grow and support a highly capable and modern Navy."
