This designation was never accepted by the squadron or the Australian Imperial Force, and was in fact officially dropped by the British by early 1918, before the formation of the RAF.

In January 1918 the unit was re-equipped with S.E.5a fighters, which it retained for the rest of the war.

68 converted to Bristol Beaufighters and in March 1942 it moved to RAF Coltishall in Norfolk.

On the night of 25/26 July 1944, Flt Lt Fred Kemp, with Farrar as navigator, failed to return after being directed to intercept a V-1 flying bomb over the Thames Estuary.

[7][8] Both the Czechoslovak element and the squadron's night fighter service were honoured in 1944 when Air Chief Marshal Charles Steele presented a badge to the squadron that shows an owl's head and has the Czech motto Vždy připraven – "Always prepared" or "Always ready".

68 Squadron was deactivated on 20 April 1945 with the personnel joining various other units including No.

On 1 January 1952 the squadron was re-formed as a night-fighter unit at RAF Wahn in West Germany.
