Description
B63G encompasses military and defensive systems installed on or integral to waterborne vessels, including weapons mountings, armor arrangements, and specialized vessel types designed for combat or defense. This subclass covers mine-laying and mine-sweeping equipment, submarine design and operation, and aircraft carrier configurations with their associated flight deck and hangar systems. The classification excludes general ship construction and hull design (covered in B63B) and focuses specifically on the offensive/defensive functional systems and specialized military vessel architectures rather than standard commercial vessel features.
