Avro Lancaster
Type: British heavy bomber.


Unquestionably one of the leading significance aircrafts of WW2, as well as one of the finest planes of aviation history, the Avro Lancaster came to exist as a result of fiasco of its forerunner.
In September 1936 the Air Staff released requirements P13/36 for a twin-engined bomber of outstanding dimensions as well as capability to be run by a pair of the very strong power plants at this time under construction: the Rolls-Royce Vulture 24-cylinder X powerplant had been favored.

Handley Page swapped to 4 Merlin engines for the Halifax bomber, nevertheless Avro followed the big-twin blueprint and the initial Type 679 Avro Manchester flew on July 25, 1939. Totally 209 Manchesters were produced by November 1941, however the aircraft had been suffering from the unreliability and inadequate performance of the powerplants. Although it was supplied to 8 Bomber Command squadrons, as well as elements of 2 others along with a flight in Coastal Command, the Manchester had been removed from operation in June 1942 and survivors had been scrapped.
However the general Manchester had been definitely remarkably great, and in 1940 the choice had been taken up to develop a longer-span model with 4 Merlin power plants.

The initial Lancaster (BT 308) flew as the Manchester III at the start of 1941. So excellent was its capabilities that it entered instant large-scale manufacturing, and Manchesters currently on the line from L7527 onwards had been finished as Lancasters (recognized from afterwards planes by their row of rectangular windows inside rear fuselage).

Operations started at the beginning of 1942 by 44 Sqn at Waddington, and on 17 April 1942 a combined force of 44 and 97 Squadrons launched a somewhat foolhardy daylight raid against the MAN plant at Augsburg, whereupon the fresh bomber’s presence had been discovered.
From this day until the end of WW2 Lancasters fly 156,000 sorties in Europe as well as dropped 608,612 long tons of bombs.
Overall manufacturing, together with 430 built in Canada by Victory Aircraft, had been 7,377 Lancasters. Of these 3.425 had been Mk I and 3,039 the Mk III using US Packard-built power plants.

Performance of the Lancaster

Bomber Harris himself summarised about the Avro Lancaster: ‘One Lancaster is to be preferred to four Halifaxes. The Hailfax suffers about four times the casualties for a given bomb tonnage. Low ceiling and short range make it an embarrassment when planning attacks with Lancasters.’

In fact, the Lancaster actually suffered a higher loss rate than the Halifax during the daylight raids which predominated at the end of WW2, and its crews were more likely to die if their aircraft was shot down. Many also suspect that the Lancaster crews, bombing from higher altitude in greater discomfort, may have been less accurate in delivering their bombs. Finally, although it carried a heavier bomb load, the Lancaster was a less useful multi-role aeroplane than the capacious Halifax, and was less well-suited for tropical operations.

But in Arthur Harris strategic bombing campaign live aircrew in enemy PoW camps were no more useful than the dead, and getting bombs ‘bang-on’ a pinpoint target was of less concern than saturating what were usually ‘area targets’.

The fact that the average Lancaster delivered 154 tons of bombs in its 27.2 sortie life, and could reach beyond Berlin, made it more useful than a shorter-range Halifax averaging only 100 tons.

With these advantages being enjoyed by an aircraft which was also cheaper to produce, it was inevitable that the Lancaster would be built in larger numbers than any other bomber, and would bear the brunt of the bombing campaign. They were despatched on 156,192 operational sorties during WW2, and some 3,836 were lost. These sorties included 107,085 on raids against Germany (23,204 of them by day) during which 2,508 Lancasters were lost (179 by day), representing nearly half of the Bomber Command total.

The Lancaster’s narrow focus and suitability for the pure bomber role was largely the result of its wartime genesis. The Halifax and Stirling had been designed in peacetime for the anticipated needs of war, whereas the Lancaster was designed in the light of real operational experience. Multi-role capability was not needed, whereas ease and economy of production was more important than crew comfort and survival.

The Lancaster Mk I (FE) had been outfitted for Far East missions with Tiger Force.
The Mk VI had high-altitude Merlin power plants and four-blade propellers along with turrets eliminated operated with 635 Squadron and 100 Group being a radar spoof carrier for countermeasures.
Additional models operated as maritime reconnaissance, air/sea rescue or photo-reconnaissance aircrafts.

Lancasters were involved in virtually every significant night strike on German cities. They quickly confirmed their efficiency by dropping 132 long tons of bombs for each plane lost in comparison with 56 (later 86) for the Handley Page Halifax and 41 for the Short Stirling.
Near Caen in Normandy, Lancasters were operated en mass in the battlefield close-support role, and they ended WW2 dropping supplies to starving People and transporting back ex- PoWs.

An order of only 300 Lancaster bomber had been made as Mk IIs using the stronger Bristol Hercules radial power plants along with bulged bomb bays as well as a ventral turret.

The Avro Lancaster Mk II and Mk I Special had been outfitted to transport the 12,000 lb light-case bomb as well as the 12,000 lb or the 22,000 llb Earthquake bombs, the H2S radar blister beneath the rear fuselage being eliminated.

The planes of 617 (Dambusters) Squadron had been outfitted to spin and launch the Wallis skipping drum bomb.

These aircrafts transported a heavier load of larger bombs compared to every other plane in the European theatre. The 12,000 lb AP bomb was required to destroy the battleship Tirpitz, and the 22,000 lb bomb ultimately shook down the persistent viaduct at Bielefeld in March 1945.
