Lancasters with the Rose rear turret (1 Viewer)

Lancaster I and III production July 1944 to end of production was 2,777, with a rate of 200 and 300 per month July 1944 to March 1945 (average 250 per month), versus 321 Rose turrets made and if the turrets were restricted to 1 Group then it was probably a post manufacture fitting, either at a maintenance unit or at the squadron that received it. Presumably the change had a modification number. Maybe try finding a photograph with the turret fitted where the serial number is shown then look up the aircraft card to see if the change is noted. After that comes the 1 Group squadron histories. The 180 mark VII, fitted with the FN.82 rear turret, were built between April and December 1945.

According to the Ministry of Aircraft Production aircraft turrets were built by Parnell Aircraft 1939 to end 1945, Brockhouse 1939 to end 1945, Lucas Birmingham Q4/39 to end 1945, Lucas Cwmbran Q3/41 to end 1945, Diamler Q2/41 to end 1945, Rose Brothers Q3/44 to end 1945, Boulton Paul Q4/44 to end 1945 and Arrow Aircraft Q2 and Q3/44.

I can say that the French Aero Navale Lancs had Rose Turrets - Just Jane at east Kirkby is one and the Motat Museum has another. Gee Lancs look big but inside they seem tiny, just like the Shackleton

They were fitted with Fraser Nash FN82 tail turrets fitted with 2x0.5" MG, not Rose turrets.

The Rose turret was one of 3 developed during WW2 for the RAF with that armament.

It is an FN82 that the Lincolnshire Aviation Heritage Centre are rebuilding for this aircraft (scroll down the following page for photos)


Boulton Paul also developed their Type D tail turret with 2x0.5" that was fitted to the Avro Lincoln.
