Avro Lancaster Mk.I - British Users part four

The Avro Lancaster is a British four-engined bomber of the Second World War era. The Mk.I version was powered by four Rolls-Royce Merlin XX delivering each of them 1280hp of power.
We're covering the next two Royal Air Force squadrons in this post:

• No.83 Squadron: This squadron received the Lancaster in May 1942 after a short period serving with the Manchester. After being reequipped with the Lancaster, they were rebased on to RAF Wyton to be part of the No.8 Pathfinder Force. They operated as marker unit for the main bomber command. They returned to RAF Coningsby and were transferred to the No.5 Group where they acted as the pathfinder unit for the independent operations of the group. They retained the Lancaster until May 1946 when they were replaced by the Avro Lincoln.
• No.12 Squadron: After being rebased to RAF Wickenby, in Lincolnshire, they were reequipped with the Lancaster replacing the Vickers Wellington medium bomber. They remained performing night raids against Germany until the end of the war in Europe. The Lancasters remained in service until August 1946 when they replaced by the Avro Lincoln.
