Number 9 Squadron is the oldest dedicated Bomber Squadron of the Royal Air Force. Formed in December 1914, it saw service throughout the First World War, including at the Somme and Passchendaele. During the Second World War, No. IX (B) Squadron was one of two Avro Lancaster units specialising in heavy precision bombing and sank the battleship Tirpitz on 12 November 1944 in Operation Catechism. Between 1962 and April 1982, the squadron flew the Avro Vulcan B.2 as part of the V-Force. In June 1982, it became the first front-line squadron in the world to operate the Panavia Tornado GR.1. In May 1998, No. IX (B) Squadron received the RAF's first Tornado GR.4, which it operated until reequipping with the Eurofighter Typhoon FGR.4 at its present home base of RAF Lossiemouth on 1 April 2019.

Number 617 Squadron is a Royal Air Force aircraft squadron, originally based at RAF Scampton in Lincolnshire and currently based at RAF Marham in Norfolk. It is commonly known as "The Dambusters", for its actions during Operation Chastise against German dams during the Second World War. In the early 21st century it operated the Panavia Tornado GR4 in the ground attack and reconnaissance role until being disbanded on 28 March 2014. The Dambusters reformed on 18 April 2018, and was equipped at RAF Marham in June 2018 with the Lockheed Martin F-35B Lightning, becoming the first squadron to be based in the UK with this advanced V/STOL type. The unit is composed of both RAF and Royal Navy personnel, and operates from the Royal Navy's Queen Elizabeth-class aircraft carriers.
