Variants

• M-105 - First version produced at the end of 1939. Installed on some pre-war fighters.
• M-105P - First mass production engine. Able to accept a motornaya pushka -mount autocannon in the "vee" between cylinder banks. Installed on the majority Soviet pre-war fighters - Yak-1, LaGG-1 and several experimental aircraft.
• M-105PA - Improved 1941 version.
• M-105PF - 1942 Modification with significantly increased power output at the expense of decreased high-altitude performance. In spite of Klimov's concerns about decreased service life, the engine was pressed into production at the insistence of Yakovlev, and further exploitation of "PF" version showed this was the right decision. The "PF" was installed on the most numerous versions of "Yak" fighters - Yak-1B, Yak-7B, Yak-9.
• VK-105PF2 & PF3 - Further increase in power output, which was believed to have exhausted the potential of the M-105 design for greater performance. The "PF2" was installed in the Yak-3 and Yak-9U.
• M-105PD - Engine with 2-stage E-100 turbocharger, experimental high-altitude version, unsuccessful prototype.
• M-105R - Decreased propeller reduction gear ratio for bomber aircraft. Installed on Pe-2, BB-22 and others.
• M-105RA - M-105PA with decreased propeller reduction gear ratio for bomber aircraft.
