The Blackburn Botha was a British four-seat reconnaissance and torpedo bomber. It was built by Blackburn Aircraft as a competitor to the Bristol Beaufort, and entered service with the RAF in 1939. It was underpowered and was quickly withdrawn from operations.

The Air Ministry ordered 442 Bothas in 1936 and the first flight took place on 28 December 1938. The RAF received its first delivery in December 1939, entering squadron service with No. 608 Squadron RAF in June 1940, the only squadron that would use the Botha operationally, the Botha being used for coastal patrols carrying 100 lb Anti-submarine bombs or 250 lb GP bombs. 

In service, the Botha proved to be severely underpowered and unstable and there were a number of fatal crashes in 1940. Both airframe and engine were subject to further development work but it was decided to withdraw the type from front-line service. At this point the Air Staff made the ill-advised decision to transfer the surviving aircraft to training units, which inevitably resulted in further casualties. 

Some Bothas were converted to target tugs and re-designated TT Mk.I. 

The type was finally retired in September 1944. In total 580 aircraft were built.
