In 1936 the Air Ministry published specifications calling for a twin-engine bomber to be powered by Rolls Royce engines. A. V. Roe & Company took up the challenge.
In 1940 the Avro Lancaster came from the development of the Avro Manchester, powered by two Rolls Royce Vulture Engines. The Manchester's engines were not sufficient enough and were underpowered and were replaced the two Vulture engines with four with Merlin engines. Roy Chadwick, the designer, then tested this magnificent plane which was renamed the Lancaster. It was great to handle and could reach high speeds depending on how much bomb load it carried. It could carry heavy bomb loads over high distances.Its maximum speed was 287 mph (462 km) and had a range of 1,660 miles (2,670 km).
