Avro 683 Lancaster
The Avro Lancaster was the mainstay of the Royal Air Force offensive capabilities during World War II. 7,377 Lancasters were produced in total.
The "Lanc" was designed by Roy Chadwick as an upgrade to the Avro Manchester. The twin-engined Manchester had proven to be seriously under-powered, so Chadwick designed larger wings to take 4 Rolls-Royce Merlin engines. It proved to be a master-stroke. Its massive bomb bay could hold a variety of bomb loads dependent on the mission. Later modifications to the bomb bay allowed the Lancaster to carry the 22,000lb "Grand Slam" bomb. This was the largest bomb load carried by any aircraft during the war.

ORBs obtained but not digitised
Information partially input, so not complete
Note: . For PURPLE, some aircraft flew with more than one Squadron therefore the data may be incomplete, or that I haven't digitised the full set of data yet. For Squadrons I am inputting data on a year by year basis. Check the Updates page for what has been uploaded.
This site will never be fully accurate or fully complete. The Operational Record Books contain many typing errors and omissions. Where this is obvious it has been corrected. Certain missions were not logged in the ORBs. As an example, senior ranking officers were banned from taking part in operations, but did anyway. They made sure that these op's were not recorded in the ORBs. If any aircraft is missing sorties or contains errors, and you can prove it, let me know using the contact page and I'll get back to you.
