Design of the Yak-41 (or possibly Yak-141; see below) began in 1975; the
first prototype flew in March 1987, followed by a second in April 1989.
Tests were conducted on the aircraft carrier _Admiral Gorshkov_.  In April
1991, one of the prototypes set several records for VTOL aircraft; it was
displayed at the Paris Air Show shortly afterwards.  One prototype was lost
in a crash (attributed to pilot error) on the carrier in November 1991,
after which development was suspended (due to lack of funds rather than any
problems with the aircraft); the surviving aircraft was mothballed.

Yakovlev have recently announced their intention to restart development of
the Yak-41, apparently as a result of renewed interest from the Russian
Ministry of Defence (a similar revival of the twin-turboprop Yak-44 AEW
aircraft is also being considered).

A more advanced version, the Yak-41M (Yak-141M?), has also been designed,
with the emphasis now on Air Force rather than Navy service.  This version
has an extensively modified airframe, with a strong emphasis on stealth
(there is a distinct resemblance to the F-22), a much more powerful engine,
and more fuel and payload.

The "Freestyle" has been referred to as both Yak-41 and Yak-141; it appears
that one designation refers to the standard fighter and one to the single
prototype modified for record attempts, but there seems to be some
uncertainty as to which is which.

Vital statistics (Yak-41/141?):  length 18.36 m, span 10.11 m, empty weight
11650 kg, max weight 19500 kg, max speed 1800 km/h (Mach 1.7), range 2100
km; power plant:  one 152.00 kN Soyuz R-97V-30 augmented turbofan, two
RD-41 lift jets; armament:  30mm cannon, 5 hardpoints, max external load
2600 kg.
