With you on that one, BTW what is the biggest naval gun currently in use?
Currently in use?
I want to say the 152mm/53 Bofors on the Almirante Grau are the largest ones in service at the moment. BAe was working on a 155mm Gun for the RN, but that got canceled late last year, and AGS (the gun on the Zumwalts) is 155mm as well, but isn't in service yet.
