Anelegant parasol-wing flying boat, created as catapult-launched or sea-based close range reconnaissater. Single huge radial M-62 engine with tractor propeller was installed on the central pylon. Airflow compensated the engine reaction due to blowing the wing. Construction was all-metal, except fabric on ailerons and tail controls.
