Design and development

The LeO 300 was designed to meet a French requirement for a BN.5 category night bomber. It was a high-wing cantilever monoplane with a crew of five. The prototype first flew in September 1933, powered by four 500 hp (373 kW) Renault 12Jb engines mounted in tandem pairs on the wings. The LeO 300 was superseded by the LeO 301 with more powerful engines but with the withdrawal of the requirement it was abandoned in final assembly and work on the programme was stopped.

gollark: There seems to be a new beta version around, so I'm upgrading instead. Upgrading is fun.
gollark: I'll just install `downgrade` and see if I can install a non-broken Qt version. If that fails, I can always just revert everything to the package versions of a week or so ago.
gollark: Okay!
gollark: All my modpacks are in MultiMC and it's generally better. I do not want a CPU-cycle-burning Java application. Another one, I mean.
gollark: ... why would I want that?
