right then, here we go.........
the correct way or writing it is "Mk.I" using a full stop to show you have abbreviated "Mark" and using roman numerals not arabic..........
Five companies, two of which were Manchester based, manufactured the Lancaster MK1.
5 or 6 companies produced the Mk.I, depending on how you look at it...........
The Manchester 'bless her' wasn't big enough to carry the 18,000lb to 22,000lb bombs
at no point did the RAF use a "18,000lb" bomb, i don't know what that's about.............
It became operational in March 1942, with its powerful 4x 1640hp Rolls Royce Merlin engines
the first lancs in service were fitted with the merlin XX or 22, the merlin 22 rated at 1,280hp, not 1,640hp, many lancasters were fitted with merlin 24s, rated at 1,620hp, only the Mk.III with Packared Merlin 224s give out 1,640hp................
The choice went to the Bristol Hercules V1 radial engine
the Mk.II was fitted with either the VI or XVI..........
two prototypes of the 'Lancaster MK11 were planned
3 prototypes were planned, however it was obvious after the second prototype that the idea would work, so the 3rd was never made........
now to just clear up some stats..........
just to make sure, the lanc Mk.I could do 287mph at 11,500ft............
Range was 2,530 miles with a 7000lb payload...........
22,000ft was her service ceiling, her absolute ceiling was 24,500ft, with the Mk.III 24,500ft was the service ceiling..........
her length was 69ft 6inches
(don't worry nearly finished)
7,374 Lancaster's were produced and flown in WW2
only 6,696 were produced during WWII, the remaining 681 were produced post war, 7,377 were produced overall.............
used by the British, Canadian, French and Argentine armies
she saw service with:
Franch Navy
Franch Government
Argentine Air Force
Egyptian Air Force
Sweedish Air Force (although only one, used as an engine test best)
RAAF
RCAF
RAF
right i think that's all.................
