The squadron is one of the oldest units of the Sapin Air Force and is usually 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. The members of the King's Own Squadron were the most successful Sapinish pilots of the war in terms of number of enemy aircraft destroyed. When the Osean Federation entered the war and began operating the Futuro Canal area, the 511 Squadron took part in joint operations with Osean pilots.
==Awards and honors==
The unit has received many Sapinish military decorations, including the title "King's Own", while its members automatically received the non-hereditary noble title of Knight. Thus the 511 Squadron's call signs were "Knight of Honor".
