In January 1917 the squadron moved to France, equipped with the Armstrong Whitworth F.K.8, beginning operations during the Battle of Arras, working alongside the Cavalry Corps, throughout 1917 (which later resulted in the Pegasus winged horses head in the Squadrons' badge).

[6] The squadron operated in support of III Corps during the Battle of Amiens in August 1918,[7] and during the attack on the Hindenburg Line in September 1918.

[7] The squadron started to re-equip with Bristol Fighters again in October 1918, but this process was not complete by the end of the war in November that year.

[9] On 1 March 1929 the squadron reformed at Bircham Newton, and was initially equipped with Airco DH.9As, re-equipping with the Fairey IIIF in November that year.

As a response to the Italian invasion of Ethiopia, the squadron was posted to the Sudan in late 1935, returning to RAF Worthy Down in August 1936, and re-equipping with the Vickers Wellesley.

35 Squadron was designated a training unit, supplementing its Battles with Avro Ansons and Bristol Blenheims late in 1939.

Sqd Ldr Alec Panton Cranswick DSO, DFC, was in 35 Sqd at the time of his death when his Lancaster was shot down on a raid to Villeneuve St George near Paris on the night of 4 July 1944, it was his 107th mission and he flew more bombing operations than any other RAF pilot in WW2, he was on his 4th operational tour.

In April 1954 the squadron re-equipped with its first jet powered aircraft type, the Canberra B.2[1] twin engined light bomber.

[19] These laydown bombs were specifically designed for the low-level penetration role, did not require a pre-release 'pop-up' manoeuvre, and improved the survivability of the squadron's Vulcans.
