Ah, Bob reminded me to pay my membership fee...
OK, "cool" was just a choice of words, but a six-barrelled Gatling gun (for instance) is the very definition of "cool"!
...
I have some armament photos, the main reason being that, if the lens is not wide enough to get the whole ship, I have to find something to take a picture of. But I don't remember ever posting them here (let me check...no photos found!), so I really do limit myself to "ship spotting" only.
Anyway, since there is an (obscure) category for armaments, be it a 16 inch gun turret or a GPMG (I don't believe we'll see anything smaller than that), let the people post!
Cheers
