No. 1435 Flight is a Typhoon FGR. 4 unit of the Royal Air Force, based at RAF Mount Pleasant, providing air defence for the Falkland Islands, South Georgia and the South Sandwich Islands. Permanently based in the islands, the aircrew and groundcrew from the UK are cycled through No. 1435 Flight, providing a 365-day, 24-hour alert. During the Second World War, No. 1435 Flight was a night fighter unit on Malta, subsequently raised to squadron status, becoming the only RAF flying squadron to be given a four digit number.
