The DEFA revolver cannon is a French 30mm autocannon developed by DEFA (Direction des Études et Fabrications d'Armement) in the early 1950s. It was designed for use in fighter jets and has been a staple armament for numerous aircraft, including the Dassault Mirage III and the SEPECAT Jaguar. The DEFA 30mm cannon features an adjustable firing rate with two options: 1,500 RPM to intercept airborne targets and 1,200 RPM to strike ground targets. Additionally, it originates from the same family of autocannons as the ADEN Cannon, and so they use the same NATO-standard 30x113mm ammunition. Being a modern autocannon with enormous firepower, demand for DEFA cannons amongst the most successful airmen of Oceanyka is very high, as it is considered superior to contemporary Soviet designs which tend to be of lower calibres.

Common Attributes - Mechanical
Auto
This weapon is fully automatic, either inherently so or by the presence of a selective-fire mechanism.
EFFECT:
This weapon can fire more than one shot each time it is used. Each subsequent shot has a progressive penalty.
Automatic weapons are considered STABLE when they're mounted on a vehicle, tripod or turret. This is different from the Stabilised SA.
- Point Blank Range - No penalty.
- Close Range (≤10m / 2sq) -> -1
- Short Range (≤50m / 5sq) -> -2 (STABLE: -1)
- Average Range (≤200m / 10sq) -> -3 (STABLE: -1)
- Medium Range (≤500m / 20sq) -> -5 (STABLE: -1)
- Long Range (≤1000m / 50sq) -> -5 (STABLE: -3)
~ Beyond this point, automatic fire is unfeasible without a STABLE firing platform. ~ - Very Long Range (≤2000m) -> (STABLE: -3)
- Extreme Range (>2000m) -> (STABLE: -5)
Belt-Fed
EFFECT:
This weapon is not fed from fixed capacity magazines, but from belts which can be made as long or short as needed.
Most machinegun belts contain 50, 100, 200 or 250 rounds. Some vehicle belts, however, can be way longer.
Unless specified otherwise, assume all small arms belts to be of 100 rounds.
