Fighter jets typically use large-caliber ammunition for their internal guns, often referred to as rounds rather than bullets. Based on common usage, especially within the United States military, fighter jets primarily use 20mm rounds.
Common Ammunition Sizes for US Fighter Jets
While 20mm is a standard caliber for many US fighter aircraft, there are notable exceptions using larger rounds for specific roles or newer platforms.
- Standard: Many US fighter jets utilize 20mm rounds.
- Exceptions: The reference highlights specific instances where different sizes are used:
- The F-35 Lightning employs 25mm rounds.
- The ground-attack specialized A-10 Warthog uses significantly larger 30mm rounds.
These calibers represent the diameter of the projectile (bullet). Larger calibers generally indicate a more powerful round, suitable for engaging hardened targets or providing heavier firepower.
Below is a summary based on the information provided:
| Aircraft Type | Typical Gun Caliber |
|---|---|
| Many US Fighter Jets | 20mm |
