The Blackburn Aeroplane & Motor Co., of Leeds, built a mix of landplanes and seaplanes prototypes culminating in the Kangaroo bomber.
- The one-off Land-Sea monoplane had a flexible undercarriage that could swap between wheels and floats.
- The Type L was an impressive 1914 floatplane, but it saw no service or production.
- Two to nine "Twin Blackburns", with a double fuselage powered by two 100hp Gnome engines, were built, but their performance was so poor they saw little use, if any.
- The Triplane was a compact pusher fighter prototype.
- The White Falcon was a one-off two-seat monoplane with similarities to the Land-Sea design.
- These twin-engined prototypes saw little use and no production, but the S.P. was developed into the Kangaroo.
- The N.IB was a 1918 prototype single-seat flying-boat fighter, intended to escort the Felixstowes, but it was too late for production.
- Three torpedo-carrying Blackbird prototypes were completed in 1918, but the type did not enter production.
