I don't have any problem understanding the system. I am curious about how easy you seem to think this would be to use.
Since you seem to know a lot about this please correct me if I am on the wrong track. The "box" you describe would hold how many 40mm grenades? Forty or fifty thousand? The weight will be how many tons? Changing boxes would seem to require major hoisting capacity. At the advertised rate of fire the box would be emptied in about one twentieth of a second. This wouldn't seem to allow time to traverse or change elevation so this isn't even spray and pray. If they get in a fire fight the crew will be pretty busy changing boxes.
How many 155mm rounds will the box hold or will it require a bigger box. I suppose a bigger crane will be required to change this box.
Yes, I am right you do not understand the system. The rate of fire is controlled by the computer operator. So he could have it fire one round an hour if he choose to. The units are are hoisted into place on the aircraft much the same way a bomber is loaded. The firing is a lot more accurate than what we are presently using.
It appears to be fairly easy to use. As a matter of fact they just signed a deal to determine if the system can be used against torpedo's fired at a ship.
The system has no moving parts for loading and firing the rounds as the rounds are stacked in the barrel, so a barrel amy have 20 projectiles.
