Another La-5 variant was the La-5UTI (Uchebno-Trenirovochny Istrebitel - training fighter) fighter trainer, which featured a second cockpit for an instructor. The starboard cannon, armoured canopy glass, armoured backrest, radio and oxygen equipment, the inert gas system and the bomb racks were removed.
The La-5UTI was tested at the NII VVS by pilots A Kubyshkin and Yu Antipov and leading engineer V Alexeenko in September 1943. It was highly praised and recommended for use by flying schools and reserve air regiments. Especially attractive were the insignificant differences from the series-built La-5F with regard to handling and performance.
A small quantity of La-5UTIs was produced at Gorkii, 28 being delivered to the Soviet Air Force. A more modified trainer at the time was the Yak-7V, which became the main fighter trainer of the second half of the war.
