F-86 SABRE VS. MIG-15 ARMAMENT|
Printable Fact Sheet
The F-86 carried six M-3 .50-caliber machine-guns like the one displayed at the museum. The M-3 was a later version of the M-2 used in World War II. The MiG-15 carried two 23mm and one 37mm cannon and was designed to destroy enemy bombers. The two cannons on display came from the museum's MiG-15.
The MiG's cannons fired heavy, destructive shells at a slow rate while the Sabre's guns fired lighter shells at a much higher rate of fire. In the high-speed dogfights typical of MiG Alley, communist pilots found it very difficult to hit the F-86s they faced.
On the other hand, Sabre pilots frequently inflicted only light damage because their machine guns lacked the punch of cannons. MiG pilots could then escape across the Yalu River into the safety of Manchuria (although F-86 pilots sometimes followed them in "hot pursuit").
