The Sukhoi Su-38 (Russian: Сухой Су-38) is a Russian agricultural aircraft, the first aircraft of this type to be designed and built by the Sukhoi Design Bureau civil aircraft section (Sukhoi Civil Aircraft (CJSC)).

Design and development

Design originally began in 1993 as a development of the Sukhoi Su-29 aerobatic aircraft.^[1]^[2] Development was suspended due to economic problems, and when restarted in 1998, the aircraft was redesigned, reducing the aircraft's size and replacing the originally planned M-14 radial engine with a LOM Praha 337S inline engine.^[1]^[3] The first prototype made its maiden flight on 27 July 2001, with a second flying by June 2002.^[1] As no users have yet^[when?] expressed interest in the aircraft, the project is currently proceeding at a low pace.^{[citation needed]}
