The Avro Lancaster is the most popular and effective RAF heavy bomber of World War Two. It is a legend that lives on right now and the contribution made by the aircraft and its crews to the freedom of our nation will, hopefully, never ever be forgotten. The prototype Lancaster took to the air for its very first flight from Woodford, Manchester, on 9th January 1941 the first production Lancaster flew later that year on 31st October. The first RAF unit to obtain the new aircraft for operations (on Christmas Eve 1941) was No 44 Squadron at Waddington, quickly followed by 97 Squadron at Woodhall Spa. The performance of the Lancaster was just outstanding. It could carry a maximum bomb load of 22,000 lb, its maximum level speed with a full load at 15,000 feet was 275 mph and it could cruise routinely at altitudes above 20,000ft at a variety speed of 200 mph. With a complete bomb load the aircraft had a range in excess of 1,500 miles. The Lancaster’s functionality, its ruggedness, reliability and to numerous its sheer charisma, endeared it to its crews who have been proud to fly this well-known thoroughbred.
An impressive total of 7,377 Lancasters have been constructed in between 1941 and early 1946. Of these, some three,500 were lost on operations and an additional 200 or so were destroyed or written off in crashes. The vast majority of these Lancasters that did survive the war were basically scrapped when their services had been no longer required, as the reverence in which the aircraft is now held had yet to create to the point exactly where their preservation seemed critical.
The Lancaster did not carry the weight of the evening bombing offensive against Nazi Germany on its personal but was supported by other earlier twin-engine bombers such as the Wellington and the other four-engine RAF heavy bombers – the Stirling and the Halifax – as nicely as medium bomber versions of the twin-engine De Havilland Mosquito. In total some 125,000 aircrew served in Bomber Command for the duration of Globe War Two more than 73,700 of them became casualties, either killed, wounded or shot down and created PoWs.
In a letter to the head of Avro soon after the war, Marshal of the Royal Air Force Sir Arthur Harris, the Commander in Chief of Bomber Command, mentioned of the Lancaster:
“I would say this to these who placed that shining sword in our hands: With no your genius and efforts we could not have prevailed, for I believe that the Lancaster was the greatest single issue in winning the war.”
Spitfire MKIs from 65 Squadron Produced in greater numbers than any other British combat aircraft ahead of or given that the War, 20,341 Spitfires had been constructed in 22 diverse variants (excluding the navalised Seafire) and the aircraft remained in production for 12 years.
The prototype’s maiden flight took spot on 5th March 1936 and Mk1 Spitfires entered RAF service (with No 19 Squadron) in August 1938.
The development potential of the original design permitted the Spitfire to establish and then preserve the air superiority so essential to the defence of Britain and to hold pace with the 19 Squadron Spitfire taking off improvements in overall performance of enemy fighters all through Globe War Two.
Spitfires fought in each operational theatre of the War and remained in RAF front-line service up to 1954. At the end of its improvement the Spitfire carried an engine generating a lot more than twice the energy of the original, its maximum take-off weight and price of climb had a lot more than doubled, its firepower had increased by a factor of five and its maximum speed had been elevated by a third all this in primarily the very same airframe.
The Spitfire played a main part in attaining ultimate victory in Planet War Two and truly deserves its location as possibly the most productive fighter style ever, and definitely as the most popular and charismatic of all time.
The Hawker Hurricane is a single of the classic fighters of all time, designed and constructed for war. It was at the forefront of Britain’s defence in 1940 and it played a significant part in reaching the victory of 1945.
Sir Sydney Camm CBE commenced the design function for the Hurricane in 1934 (Camm went on to design and style the Typhoon, Tempest, Hunter and Harrier). The prototype Hurricane (K5083) created its maiden flight on 6th November 1935 and deliveries to the RAF commenced just just before Christmas 1937 to 111 Squadron at Northolt (eight months ahead of the Spitfire). The Hurricane was the 1st British monoplane eight-gun fighter, the initial RAF aircraft to exceed 300 mph in level flight and the first production fighter with a retractable major undercarriage.
In the course of the Battle of Britain, RAF Fighter Command fielded far more Hurricanes than Spitfires, and Hurricanes achieved a similarly higher proportion of combat kills during the Battle.
A remarkable total of 14,533 Hurricanes were built and the aircraft served operationally on each and every day throughout hostilities, in every operational theatre and in several roles. At the finish of Planet War Two in 1945, Hurricanes had been nonetheless in the front-line helping to make sure final victory in the Far East.
With the finish of the war, Hurricanes have been speedily retired from service as the fast progression of aircraft style and capabilities had efficiently rendered them obsolete and the aircraft’s job was done. The vast majority have been simply scrapped and broken up. Sadly, these days, there are only 12 Hurricanes nonetheless airworthy worldwide only six of these in UK. The BBMF is proud to operate two of these historically important and rare aircraft.
