Standardized on the A-3's longer rear fuselage, strengthened wing, shortened undercarriage oleo legs, ETC 2000/XII wing racks and an increase in maximum external load. The first proposal for what would become the He 274 started with six airframe orders for what had been known as the He 177H,[9] which were requested from Heinkel as early as mid-October 1941, all to have four individual engines, and intended to use what were essentially production He 177A-3 fuselages mated to longer-wingspan, four-engined wings.

Heinkel He 177-277-274, Airlife Publishing, Shrewsbury, England 1998. Construction of the two prototypes, the He 274 V1 and V2 did not commence until 1943. Proposed high altitude pressurised version, never built under the designation, and later developed into the Heinkel He 274. Heinkel He 274. The powerplants selected were the same type of Daimler-Benz DB 603A Kraftei "power-egg" unitized engine installations, complete with their He 219-style annular radiators that were placed on the wings of the quartet of ordered He 177B prototypes, but for the He 274's use, added DVL-designed TK 11 turbochargers, one per engine, for better power output at high altitude. [2] Heinkel had foreseen that an individually engined version of his bomber would someday be preferred, quite unlike the requested fitment of the coupled pairs of Daimler-Benz DB 601 inverted V12 engines, each known as a DB 606 — weighing some 1.5 tonnes apiece — which ended up being fitted to all of the eight He 177 V-series prototypes at the request of the RLM, and the Luftwaffe High Command, with the concerned government agencies citing the desire for a dive-bombing capability to be present even with a heavy-bomber-sized offensive warplane, something Ernst Heinkel vehemently disagreed with. Largely unnecessary defensive armament was restricted to a single forward-firing 13 mm (.51 in) caliber MG 131 machine gun and remotely controlled dorsal and ventral Fernbedienbare Drehlafette FDL 131Z gun turrets each containing a pair of MG 131s and with the dorsal turret operated from a slightly offset Plexiglas domed sighting station in the roof of the flight deck as most A-series He 177s were, with the ventral unit aimed from the rear of the ventral Bola gondola. | Content ©www.MilitaryFactory.com.

The He 274 V1 was being readied for flight testing at Suresnes in July 1944 when the approach of Allied forces necessitated the evacuation of Heinkel personnel working on the project. By April 1939, interest in developing a high-altitude version of the He 177 had arisen, and on April 27, 1939, the first proposal for such an aircraft was presented to Heinkel by his firm's engineering staff.

By October 1941, a more developed "He 177H" specification for a high-altitude Heinkel-designed heavy bomber[6] had emerged from the proposed A-2 and A-4 coupled-engine designs, with the intent of carrying a 2,000 kg (4,410 lb) bombload over a maximum range of some 3,000 km (1,895 mi), and accepted by the RLM for the first time, an individual four-engine installation was being considered for any He 177-based bomber airframe, with a quartet of either BMW 801 or DB 603 engines among the choices of powerplants being specified, with the same sort of reduced-armament defensive weapon format as the A-2 and A-4 were intended to have. Heinkel He 274. The He 274 also featured a pressurized compartment for a crew of four, this employing double walls of heavy-gauge alloy, hollow sandwich-type glazing and inflatable rubber seals, a pressure equivalent to that at 2,500 m (8,200 ft) being maintained at high altitude. It was renamed the AAS 01A. The company had designed a relatively small, 'sporty'-looking aircraft, with a sleek, streamlined fuselage. The defensive armament had been reduced to a trio of Ferngesteuert-Lafette FL 81Z remote gun turrets, each with a twin-barrel MG 81 armament installation each in an upper nose mount, forward dorsal and (as part of the Bola casemate-style gondola under the nose) forward ventral location each, and a single MG 131 machine gun in an He 177A-1-style, pressurized manned flexible tailgun emplacement. Work began on the He 274 in 1941, under the designation He 177H. The Heinkel He 274-page contains all related products, articles, books, walkarounds and plastic scale modeling projects dedicated to this aircraft.. The main difference was in its engines. [4] The A-2 version had even been considered for a pioneering in-flight refueling capability, possibly using Ju 290 maritime patrol aircraft as the tankers - with such capability, the range of the A-2 would have been extendable to some 9,500 km (5,900 mi) of total flight distance.
