The Handley Page HP.52 Hampden was a British twin-engine medium bomber of the Royal Air Force serving in the Second World War. With the Whitley and Wellington, the Hampden bore the brunt of the early bombing war over Europe, taking part in the first night raid on Berlin and the first 1,000-plane raid on Cologne. The newest of the three medium bombers, the Hampden, known as the "Flying Suitcase" because of its cramped crew conditions,[1] was still unsuited to the modern air war and, after operating mainly at night, it was retired from Bomber Command service in late 1942. While the Hampden was powered by Bristol Pegasus radial engines, a short-lived variant known as the Handley Page Hereford instead featured in-line Napier Daggers. Design and development Handley Page designed the Hampden to the same specification as the Wellington (Air Ministry Specification B.9/32) for a twin-engined day bomber. One prototype HP.52 (Serial K4240) was ordered which first flew on 21 June 1936. The first production batch of 180 Mk I Hampdens was built to a production Specification 30/36 with the first aircraft flying on 24 May 1938. Lady Katharine Mary Montagu Douglas Scott, Viscountess Hampden, christened the first flight at Radlett aerodrome in 1938.[2]

The Hampden's cockpit The Hampden used a stressed skin design reinforced with a mixture of bent and extruded sections with the wing having a single main spar. Construction was from sections prefabricated then joined. The fuselage was in three major sections – front, centre and rear. The centre and rear sections were themselves made of two halves. This meant the sections could be fitted out in part in better working conditions before assembly. In a similar way, the wings were made up of three large units: centre section, port outer wing and starboard outer wing, which were in turn subdivided.[3]

The Mk I had a crew of four: pilot, navigator/bomb aimer, radio operator and rear gunner. Conceived as a fast, manoeuvrable, "fighting bomber", the Hampden had a fixed .303 in (7.7 mm) Browning machine gun in the forward fuselage. To avoid the weight penalties of powered turrets, the Hampden had a curved Perspex nose fitted with a manual .303 in (7.7 mm) Vickers K machine gun and a .303 in (7.7 mm) Vickers K installation in the rear upper and lower positions. The layout was similar to the all-guns-forward cockpits introduced about the same time in the Luftwaffe '​s own medium bombers, notably the Dornier Do 17. The guns were thoroughly inadequate for defence and by 1940, the single guns had been replaced by twin Vickers K guns. The fuselage was quite cramped, wide enough only for a person. The navigator sat behind the pilot and access in the cockpit required folding down the seats. Once in place, the crew had almost no room to move. "I did my first flight and first tour on Hampdens. A beautiful aeroplane to fly, terrible to fly in! Cramped, no heat, no facilities where you could relieve yourself. You got in there and you were stuck there. The aeroplane was like a fighter. It was only 3 feet wide on the outside of the fuselage and the pilot was a very busy person. There were 111 items for the pilot to take care of because on the original aircraft he had not only to find the instruments, the engine and all that, but also he had all the bomb switches to hold the bombs. – Wilfred John 'Mike' Lewis[4] A total of 1,430 Hampdens were built: 500 by Handley Page, 770 by English Electric at Samlesbury in Lancashire and 160 in Canada in 1940–41 by the Canadian Associated Aircraft consortium (although some were retained in Canada, 84 were shipped by sea to the United Kingdom).
