Before the design on the Yak-1 started, Alexander Yakovlev
and his design Bureau had been working on light transports and trainers.
However, Yakovlev wanted to build a front-line fighter. He received permission
to work out a design for a 'frontal-fighter', a fighter that was to gain air
superiority over the front line and that could withstand the rigors of a
forward (and mostly primitive) airstrip.

Alternatively to the 20 mm
ShVAK cannon a 0.50 inch (12,7 mm) Beresin UBS
gun, 250 rounds, could be installed. Later
prototypes were altered, as can be expected, and
featured a separate duct for the oil cooler
under the engine, air inlets for the carburetor
in the wing leading edges, ejector exhaust
stubs, increased chord of the fin, a fixed
tailwheel, and a revised cockpit/rear turtledeck
combination. | |
