Mount Pleasant in the Falkland Islands marks four decades since its construction

Mount Pleasant Complex is marking its 40th year as an RAF fighter and transport presence in the Falkland Islands.

Around 33 miles southwest of the capital, Stanley, it was officially opened in May 1985 and became operational the following year, making it the newest permanent air base for the RAF.

In a post on X, the Falkland Islands Government Office in London said: "Mount Pleasant Complex is central to the safety and security of our islands and we're hugely grateful to all who have served there."

• Permanent home in the Falklands for Sea Harrier and Lynx that crippled Argentine sub
• MOD insists it's confident in the security of the Falkland Islands despite claims of downgrade

The RAF's 1435 Flight, operating four Typhoon FGR4 fighter jets, as well as No. 1312 Flight, with a Voyager tanker and an Atlas A400M, are currently based at RAF Mount Pleasant.

Accompanying RAF personnel on the ground have a range of roles, from radar operators to weapons technicians, in support of the Typhoons.

Mount Pleasant Complex (MPC) also facilitates civilian flights from the airfield.

The UK has maintained an active military presence in the Falkland Islands since the war between Argentina and Britain, which lasted from 2 April to 14 June 1982 and claimed 255 British lives.

It has invested heavily in the islands' defences, including the construction of RAF Mount Pleasant.

The British Army also provides a constant garrison on the Falkland Islands to support the Navy and Air Force with air defence and infantry specialists.

The austere terrain and challenging climate can provide unique training opportunities for soldiers, too.

The international political landscape has changed since 1982, and Argentina is now a democracy, committed to the peaceful resolution of issues over the islands.
