Build at Kaufman for the Caliphate of Estalia which lies in the Delhi Subsector of the Holowon Sector. This is a class of TL–10 System Defense Boat with the best armor available to take heavy punishment. It has the best 4 G maneuver drive and an oversized fusion power plant for maximum evasive agility. It is armed with a pair of magazine fed 50kg missile racks. The Caliphate of Estalia relies on this class to protect the Kaufman (Holowon 0122 B86A5D0-A) starport and native shipping in system it controls. They can also provide close gunship support for marine units. There is a squadron of 10 of these flying submarines. They are equipped for action in the planets hydrosphere and armored to explore its greatest depths. They provide atmospheric and near space COACC. They can operate in space and are streamlined for ocean refueling. As yet they are reliant on the 800 ton Carrack Class Transports for inter-system transport and redeployment. The crew includes a pilot/captain and a weapons officer.
