also, the GK has A LOT of deck penetration. it needs an reload room and magazine, while the phalanx has all that on-mount (although some of it is sometimes recessed, as was done here). this is why you cannot just swap an GK and an Phalanx.
Crap. Didn't know that. I thought GK was all "on-mount" as well.
Opinions, then...
options:
1.) Switch all my ships back to Phalanx
2.) Leave them with GK, but move them around to where they will fit
(nightmare scenario)
3.) Use a combination of both, Phalanx on smaller ships or in tight spots, GK on larger ships where there is sufficient room for the deck penetration
4.) Say that GK has all their hoo-haw on mount like the Phalanx does
(stubborn-its-my-world-and-sometimes-RW-rules-don't-apply scenario. also known as "aw hell, I don't want to change everything again". lol)
