The Tupolev I-4 was a Soviet sesquiplane single-seat fighter. It was designed in 1927 by Pavel Sukhoi, his first aircraft design, and the first Soviet all-metal fighter.

Design and development[edit]

After the first prototype (under the development name ANT-5), the I-4 was redesigned with a new engine cowling to decrease drag, added rocket launchers on the upper wing, and a larger tailfin. The lower wing was nothing more than an attachment for the wing struts; it was (almost) removed in the second series (I-4bis).

Operational history[edit]

The I-4 was used as a parasite fighter in experiments with the TB-3 bomber. The aircraft was in Soviet service from 1928–1933. A total of 369 were built.
