RAF Lightning Units of the Cold War

B-47 Stratojet Units of the Cold War

Mosquitos in the Far East

Mitsubishi Ki-21 'Sally' Units in Combat

P-47N Thunderbolt Units of the Central Pacific

RAF Lightning Units of the Cold War

The mainstay of the RAF air defences during the Cold War, the iconic English Electric Lightning also contributed to the air defence of West Germany in the 1960s and early 1970s as well as Cyprus and Singapore during the late 1960s. The Mach 2-capable Lightning, which entered service in 1960, represented a quantum leap in performance for the RAF fighter force. The type served with nine frontline RAF squadrons, including two squadrons based in Germany and one each in Cyprus and Singapore.

B-47 Stratojet Units of the Cold War

One of Boeing’s most significant aircraft, the B-47 Stratojet was the most numerous jet bomber (more than 2000 built) ever fielded by the USAF’s Strategic Air Command (SAC). Initially plagued by design and production problems, the B-47 eventually proved to be a successful medium-range bomber, an influential testbed and an effective Cold War reconnaissance platform.

Mosquitos in the Far East

RAF and RAAF Mosquito units played an important role in forcing the Japanese retreat from Burma and the Far East, undertaking both long-range strike and reconnaissance missions. Aircrews flew the Mosquito to its limits over hostile terrain against a determined enemy. Even though its revolutionary composite wood construction was compromised by the damp climate and poor workmanship, both the aircraft and aircrews delivered in the fight against the Japanese.

Mitsubishi Ki-21 ‘Sally’ Units in Combat

When the first Ki-21s to reach the frontline were delivered to the 60th Sentai in August 1938, the Imperial Japanese Army Air Force had an aircraft that was as good as the best twin-engined bombers in service anywhere in the world. When the Pacific War commenced in December 1941, the Ki-21 units supported the invasion of Thailand, Burma and Malaya, as well as continuing to attack targets in China. Codenamed the ‘Sally’ by the Allies shortly thereafter, the improved Ki-21-II was at the forefront of operations in Southeast Asia and the Dutch East Indies well into 1942.

P-47N Thunderbolt Units of the Central Pacific

The P-47N was the final variant of the most produced American fighter of World War 2. Its late introduction to the war limited its combat use to the final four months of the conflict, during which time it excelled as a long-range strike fighter. The four N-model fighter groups in the Central Pacific (flying from bases on Ie Shima and Iwo Jima) from May to August 1945 saw extensive action over the Japanese home islands, the fighter’s new wing and additional fuel tankage making it the ideal aircraft to strike at enemy fighter bases while B-29 raids bombed Japan’s industrial infrastructure.
