Blackburn Botha
| First flight | 28 December 1938 | |
|---|---|---|
| Introduced | 12 December 1939 | |
| Retired | September 1944 | |
| Number built | 580 | |
The Blackburn B.26 Botha was a competitor to the Bristol, and entered service with the RAF in 1939. It was underpowered and was quickly withdrawn from operations.
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.
The type was finally retired in September 1944. In total, 580 aircraft were built.
