 The Operational Administration of the Soviet Navy worked out the requirements in May 1925 for a conversion that would have made Izmail into an aircraft carrier with a top speed of 27 knots ( 50 km / h ; 31 mph ) and a capacity of fifty aircraft . She would have been armed with eight 183 @-@ millimetre ( 7 @.@ 2 in ) guns and her armour reduced to a maximum of 76 millimetres ( 3 @.@ 0 in ) . This proposal was approved by Alexey Rykov , Chairman of the Council of the People 's Commissars on 6 July 1925 . The plan was cancelled on 16 March 1926 after the Red Army managed to gain control of a commission appointed to review the needs of the Navy , and the Army was strongly opposed to spending additional money on naval projects . She was scrapped beginning in 1931 in Leningrad .
