I'm sure it's been that way since the beginning, but at least changing it wouldn't be a giant red-ass like other platforms. After all, a pod doesn't require a complete redesign...
Any maintenance/modification to the Harrier is a giant red-ass. I get your point, though.
It takes about a half a shift to get the gunpack removed, but about 2 shifts to put it on, depending on how long it takes you to get it high powered.
The gun has 300 rds (25mm), and with the new software and a Litening pod is very accurate A/G.
A/A...........not so much, but then again, I've never shot it A/A for real (banner shoot, etc).
