The Lancaster B Mk I is a British bomber. It was introduced in Update 1.43.

Developed from the troublesome Avro Manchester, the Avro Lancaster is a long-range heavy bomber optimised for delivering huge payload over long distances. Compared to its contemporaries like the American B-17 or the German Fw 200, the Lancaster carries twice the payload while being generally easier to handle. Because of this, the "Lanc" is an ideal bomber for destroying bases and airfields with bombs from high altitude.

Because of the optimization for large payload and good manoeuvrability, the early Lancaster have a very poor set of defensive armaments consists of a small .30 cal machine guns. This will not help to ward off any pursuing enemy fighters and thus leaves the plane vulnerable to any other planes save for another heavy bomber. On the other hand, the Lancaster's ease of control and overall good flight performance allows the plane to reach the destination relatively quickly and get the job done.
