No. 101 Squadron (RAF): Second World War

At the outbreak of the Second World War, No. 101 Squadron had just be re-equipped with the Bristol Blenheim IV. Until the summer of 1940, No. 101 Squadron was a reserve squadron. It flew its first Blenheim operation on 4 July 1940, and was occupied with the attack on the German invasion fleet gathering the channel ports.

In April 1941 the squadron began to transfer to the Vickers Wellington, joining the main bomber force in June 1941. After just over a year operating the Wellington, the squadron converted to the Avro Lancaster I and III.

From October 1943 it began to use ABC jamming equipment, while remaining with the main bomber force. ABC, or Airborne Cigar was a system designed to jam the radio frequencies used by the Germans to transmit a running commentry on the night's events to their night fighters. When equipped with the ABC equipment, No 101 Squadron Lancasters carried an eighth German speaking crew men, whose role was to listen in to the German radio transmissions and decide which ones to jam. As a result of its extra role, No. 101 Squadron eventaully expanded to contain 42 aircraft.

It suffered exceptionally heavy casualties, losing 145 Lancasters on operations, as German night fighters could detect the jamming transmissions. Only three other squadrons lost most Lancasters than No 101. One countermeasure was the early use of the Rose tail turret, with two 0.50in machine guns, introduced in May 1944, five months before the turret was cleared for general use. Unusually for a squadron involved in Electronic Counter Measures, No. 101 Squadron did not join No 100 Group.

At the end of the war No. 101 Squadron was one of the Lancaster squadrons used in Operation Manna, dropping much needed food into Holland.
