Operational profile

Recognition and use

This heavily armored five-hundred-ton system-defense ship trades interstellar movement for a large particle-beam bay, six-gravity acceleration, emergency power, advanced sensors, and a hardened bridge. A boarding boat, brig, troops, medical support, and substantial recovered cargo volume support prolonged local patrols.

A particle barbette, laser and mixed defensive turrets, and five point-defense nodes supplement the main bay. It is formidable near its bases but cannot jump; strategic redeployment requires a carrier or tender, and its large crew and military systems demand steady institutional support.
