Performance
Speed, range, altitude and engagement capability.
| Effective range Distance at which the weapon reliably hits point targets. Higher extends engagement envelope. | 200 m |
|---|---|
| Rate of fire Rounds per minute (cyclic). Higher increases suppression and hit probability. | 900 rpm |
| Muzzle velocity Projectile speed leaving the barrel. Higher means flatter trajectory and better armor penetration. | 715 m/s |
Firepower
Armament, payload and guidance.
