NO NEED TO PAY UNTIL 31 MAY Short Stirling Dating from 1943 Studiette Solid Wooden 1/72 aircraft model kit The Short Stirling was a British four-engined heavy bomber of the Second World War. It has the distinction of being the first four-engined bomber to be introduced into service with the Royal Air Force (RAF). The Stirling was designed during the late 1930s by Short Brothers to conform with the requirements laid out in Air Ministry Specification B.12/36. Prior to this, the RAF had been primarily interested in developing increasingly capable twin-engined bombers, but had been persuaded to investigate a prospective four-engined bomber as a result of promising foreign developments in the field. Out of the submissions made to the specification, Supermarine proposed the Type 317, which was viewed as the favourite, whereas Short's submission, named the S.29, was selected as an alternative. When the preferred Type 317 had to be abandoned, the S.29, which later received the name Stirling, proceeded to production. In early 1941, the Stirling entered squadron service. During its use as a bomber, pilots praised the type for its ability to out-turn enemy night fighters and its favourable handling characteristics, whereas the altitude ceiling was often a subject of criticism. The Stirling had a relatively brief operational career as a bomber before being relegated to second-line duties from late 1943, due to the increasing availability of the more capable Handley Page Halifax and Avro Lancaster, which took over the strategic bombing of Germany. Decisions by the Air Ministry on certain performance requirements (most significantly to restrict the wingspan of the aircraft to 100 feet [30 m]) had played a role in limiting the Stirling's performance; the 100 ft limit also affected earlier models of the Halifax (MkI and MkII) though the Lancaster never adhered to it.[3] During its later service, the Stirling was used for mining German ports; new and converted aircraft also flew as glider tugs and supply aircraft during the Allied invasion of Europe in 1944–1945. In the aftermath of the Second World War, the type was rapidly withdrawn from RAF service, having been replaced in the transport role by the Avro York, a derivative of the Lancaster that had previously displaced it from the bomber role. Several ex-military Stirlings were rebuilt for the civilian market. Operational history In July 1940, the first production Stirling departed Rochester; in August 1940, it was delivered to No. 7 Squadron at RAF Leeming, North Yorkshire.[22] Following a four-month working-up period in which crews adapted to operating the type, the Stirling attained operational status in January 1941. On the night of 10/11 February 1941, the first operational combat mission was performed, flown by the first three Stirlings, against fuel storage tanks at Vlaardingen near Rotterdam, in the Netherlands, all but two bombers were deployed during the mission, which was considered to have run smoothly.[22] By the end of 1941, more than 150 Stirlings had been completed and three RAF squadrons had been equipped with it. Stirlings flew on day and night bombing operations and had been found to be most capable of standing up to enemy interceptor aircraft by using a sweeping combination of fighters and bombers, in what was known as "Circus" operations.[22] Short Stirling of No. 1651 Heavy Conversion Unit c.1941 being loaded with bombs. From late 1941, the Stirling played a pioneering role in the formation of the RAF's Pathfinder squadrons, specialist navigation and target-finding squadrons to assist Main Force squadrons.[22] From the spring of 1942, the number of Stirlings in service began to increase.[39][40] From May 1943, raids on Germany were often conducted using over a hundred Stirling bombers at a time.[41] Stirlings were amongst the RAF bombers used during the first 1,000 bomber raid against Cologne.[42] Norris observed that, by 1942, the type had "given plenty of punishment to the Germans and was also proving that it could itself take punishment to an incredible extent".[43] There were several incidents in which damaged aircraft, such as one Stirling which suffered a head-on collision with a Messerschmitt Bf 109 fighter over Hamburg, were able to return to base.[42] Despite the "disappointing performance" at maximum altitude, Stirling pilots were delighted to discover that, due to the thick wing, they could out-turn the Junkers Ju 88 and Messerschmitt Bf 110 nightfighters they faced.[44] Its handling was much better than that of the Halifax and some preferred it to the Lancaster. Based on its flight characteristics, Flt Lt Murray Peden (RCAF) of No. 214 Squadron RAF described the Stirling as "one of the finest aircraft ever built".[45] A consequence of the thick wing was a low ceiling; many missions were flown as low as 12,000 ft (3,700 m). This was a disadvantage if crews were attacking Italy and had to fly through (rather than "over") the Alps. When Stirlings were on operations with other RAF bombers which could fly higher, the Luftwaffe concentrated on the Stirlings. Within five months of being introduced, 67 out of 84 aircraft had been lost to enemy action or written off after crashes. The Stirling's maximum bomb load could be carried for only around 590 miles (950 km). On typical missions deep into Germany or Italy, a smaller 3,500-pound (1,600 kg) load was carried, consisting of seven 500-pound (230 kg) GP bombs; this payload was in the range of that which was already being carried by the RAF's medium bombers, such as the Vickers Wellington and by 1944, the de Havilland Mosquito. Perhaps the biggest weakness present in the design was that, although the bomb bay was large at 40 ft long (12 m), it had a pair of structural dividers that ran down the middle, limiting the bay to nothing larger than the 2,000-pound (910 kg) bomb.[46] As the RAF started using the 4,000-pound (1,800 kg) "cookies" and even larger "specials", the Stirling became less useful. The Handley-Page Halifax and especially the Avro Lancaster offered better performance and when these aircraft became available in greater numbers from 1943, the Stirlings were relegated to secondary tasks.[24][N 6] During the type's service with Bomber Command, Stirlings flew a total of 14,500 sorties, during which 27,000 tons of bombs were dropped; 582 aircraft were lost in action while a further 119 were written off. By December 1943, Stirlings were being withdrawn from frontline service as bombers.[24] The aircraft remained in service for minelaying operations in the vicinity of German ports ("Gardening"), electronic countermeasures, dropping spies deep behind enemy lines at night and towing gliders.
