The rank of Lieutenant Commander (O4) is the third most senior non-flag-officer officer rank in the Imperial Navy.

Description (Specifications)[edit]

The smallest Spaceships of the Imperial Navy are under the charge of a Lieutenant Commander, if not commanded by a more senior officer. Naval Lieutenant Commanders may also hold staff appointments, or command Squadrons of small craft aboard larger vessels.

History & Background (Dossier)[edit]

The rank of Commander has a long history from its first inception in the wet-navies of pre-spaceflight planetary naval services. It is shortened from the old term Master and Commander.

This rank's name indicates that the holder deputised for that commander or was their second-in-command.
