Far Guy was the Supervisor of “The Gun Shop” for a number of years before he went into the Weapons Release Shop as a Supervisor….then he went to Quality Assurance and Safety Inspection. Before “The Gun Shop” he was in Weapons Loading.

Yes that thing on casters is a gun.
A 20 MM Gatling Gun. It has six barrels it shoots 6,000 rounds a minute. The rounds could be high explosive incendiary (HEI), armor piercing or target practice (TP) usually every 7th round was a tracer. The F-4 Fighter could carry up to five of these guns.

He is bore sighting using a laser. It is bore sighted to 2,000 feet.
The Pilot squeezes the trigger for short bursts because long bursts would warp the barrels. The shortest burst recorded was 25 rounds.
It was possible for the gun to try to put more than one round in a barrel at a time when this happened several things would break inside and there would be gun powder all over. The only way to make things safe was to spray WD 40 all over everything and soak up all the gun powder.
There were 22 of these guns in the gun shop. They also stored all the ammunition. The Gun Shop itself was located in a very secure spot on base …away from everything else in a rocket storage building. No one got to go out there unless you were escorted. I visited once during an open house.
Gulfport Mississippi was like a second home during the time at The Gun Shop. All the live fire exercises were held out over the Gulf. The base at Gulfport was what is called a bare base, they had to take everything they needed from home base ( an exercise in mobility).
Shots were fired from the gun aboard an F 4 at a big aluminum dart shaped target that was towed by another aircraft. At first the target would be brought over the runway and the cable that was attached to it was cut so that the target would land safely. One time the cable failed to break away after being cut so they headed back over town toward the Gulf…when the cable finally broke…it went completely through a Barber Shop in downtown Gulfport…thankfully it was Monday and the Barber Shop was closed. From then on the target was dropped off over the Gulf.

A 20MM round
