Battle Honours are awarded by the Sovereign to Royal Air Force squadrons to commemorate the squadron's role in a particular operation. This practice was inherited by the RAF from its Army and Navy predecessors upon its creation in 1918. Several squadrons therefore carry honours awarded when they were a part of the Royal Flying Corps or Royal Naval Air Service. Battle honours are not awarded for every operation conducted by British forces and not every squadron taking part in an operation is entitled to emblazon the honour on their standard, only those involved in contact with the enemy. In 1943, King George VI approved the award of a Standard to RAF squadrons who have 25 years of service in either the RAF, Royal Auxiliary Air Force, Royal Naval Air Service or Royal Flying Corps. Standards can also be awarded to units which have "earned the King's appreciation for outstanding operations". A squadron can embroider the names of up to 10 battle honours on its standard, known as "emblazoning the honour". Below is lists of battle honours which may be claimed by RAF squadrons.
