Which gun system has 2 separate systems to allow the operator the ability to select the feeds on the gun feeder assembly?

• A. GAU-18
• B. GAU-21
• C. GAU-22
• D. GAU-23

Answer: (D)

Understanding redundancy in gun feed systems helps explain why this option stands out. Some aircraft cannons are designed with a single feed path, while others include a dual-feed setup that lets the operator choose between two independent feed systems through the gun feeder assembly. This two-path arrangement provides reliability and flexibility in flight: if one feed path encounters a jam, misfeed, or supply issue, the operator can switch to the other path without stopping to repair or reconfigure, keeping fire capability available. The GAU-23 is built with this dual-feed capability, allowing the operator to select between the two feeds directly via the gun feeder assembly. This design feature is what makes it the best answer for a question about having two separate systems to select feeds. The other gun systems listed do not provide this same dual-feed selection arrangement in the feeder assembly.
