Nice work superboy

Only one question, why does the rear gun of the second ship (Iran) faces forwards...?

JSB, acelanceloet, Gollevainen, Skyder2598, eswube, Hood : thanks

update sam launcher by acelanceloet comment, what's the difference between Mk 29 launcher and italian Albatros launcher ? nothing

Skyder2598 : the rear gun faces forwards in peacetime because gun barrel off side the stern, can't move forward because Limbo launcher. but no problems and all weapons can firing, this is the classic case that not found in this year
