511 Esuadrón "del Rey" (English: 511 Squadron "King's Own") is a fighter squadron in the Air Force of the Kingdom of Sapin that has seen action in the Belkan War of 1995. Its primary aircraft is the Eurofighter Typhoon.
The squadron was one of the oldest units of the Sapin Air Force and was headquartered at Gran Rugido Air Base.
When the Belkans began their invasion of the northern region of the kingdom in March 1995, the 511 Squadron was one of the units that responded. They engaged the Belkan Air Force in the skies of Arlon, shooting down a total of 46 Belkan fighters. In the process, the squadron lost four aircraft due to extensive damage, but none of its pilots were killed.
