DI-8 / ANT-46, A.N.Tupolev

he DI-8 or ANT-46 was a two-seat fighter version of the SB twin engine bomber. It was armed with two recoilless 45mm APK-11 cannon in the outer wing panels, next to the ailerons.
Project started in November 1934, first flights August 9-13 1935, factory tests June 1936 - but no State Acceptance tests followed.
Interest in the gun quickly terminated (together with gun designer), and the DI-8 was abandoned.
