| The first two-seat fighter of indigenous Soviet design,
the 2I-N1 (the designation signifying Dvukhmyestny
istrebitel, or two-seat fighter, with one Napier engine)
was a single-bay unequal-span biplane of wooden construction
with a monocoque fuselage and a 450hp
Napier Lion water-cooled engine. The sole prototype of
the 2I-N1 (also referred to as the DI-1) was flown on 12
January 1926, and demonstrated a performance higher
than that of contemporary single-seat fighters. Armament
comprised one fixed 7.62mm gun and a similar
calibre weapon on a ring mount in the rear cockpit. On 31 March 1926, high speed tests during the ninth flight
terminated with the destruction of the aircraft as a result
of a structural failure, no further development
being undertaken.
