This designation was allocated to the
tandem, dual-control, trainer version
of the Yak-15. The pupil's cockpit was
added in front of the original cockpit,
and a new streamlined canopy was
designed to cover both, with a separate
sideways-hinged hood for each cockpit.
To make room for the front cockpit
the guns were removed, and the
Yak-21 was unarmed. Fuel capacity
was unaltered. The single prototype
had callsign 101, believed in Yellow,
and a capital V (looking like B in
Russian) was painted on the rudder.
Flight testing began in May 1947, but
by this time it had been decided to
build the Yak-17UTI with a nosewheel
