Farman F.270

Development

The F.270 of 1933 was a development of the earlier F.60 and F.150 series it was a mixed wood and metal sesquiplane with a single vertical tail unit. Powered by two Gnome-Rhône 14Kbr radial engines mounted above the lower wing. It had a wide-track tailskid landing gear and three machine-gun positions, one in the balcony type nose, one amidships and one in a ventral position that fired though a trap door in the floor.

In 1934 an improved variant was produced, the Farman F.271, with engine power boosted to 800 hp (597 kW) additional nose glazing for the bomb/torpedo aimer, and larger navigators station, and the ventral trap door replaced with a retractable bathtub gondola. Neither type entered production but the F.271 was later tested on floats.
