Description/Overview:
            The Sentinel class was part of the emergency rearmament program of the Jovian Defense Forces started in 2178 and completed in 2181.  Sentinel class ships were produced at the end of 2178 as it became clear that colonization fleets would be necessary due to the aggression of the increasingly corrupt Earth Federal Republic Space Navy and the growing possibility of the Ceres Regency supporting such an invasion of the Jovian worlds.  The Sentinel class was nothing more than a rearmed and retrofit UN Solar Empire Harpy class heavy cruiser that was given improved beam turrets and sublight plasma-drive engines.  Outside of those two systems the ship was basically the same.  Battle robots replaced the multiped tanks, but the shuttlecraft was kept for ship-to-shore operations.  That feature (the shuttecraft) made the Sentinel class perfect for detailed survey missions of potential colony exo-planets without risking the whole vessel.  As the Extra-Solar Expeditionary colony fleets began to take shape in 2179, many of the emergency ships like the Sentinel found themselves being sent off into the unknown of galactic space to help mankind survive.
