Jacobite Minelayer

design by Nick Bradbeer

Officially designated an 'Interdiction Support Vessel' the Jacobite was a multirole minelayer, operated by the IISS in peacetime in support of Quarantines, but seconded to the Navy in times of war for blockade duties. Based on the ubiquitous Sulieman class hull, the Jacobite looked outwardly like a Scout/Courier, except for the arrangement of the HEPlaR exhausts and hangar doors on the aft bulkhead.

The aft half of the hull was given over to reconfigurable hangar space. Two six-ton and one twenty-four ton space could serve as small craft hangars or cargo bays without alteration, or could have mine racks loaded for dispersal of stationary mines. The single large hangar could also be configured with autoloading equipment to serve as an extended magazine for the weapons turret.

Each of the lower hangars was equipped with a grounding ramp to allow ground vehicles to be carried and unloaded. The upper hangar had no such ramp, but an extendable beam hoist allowed heavy objects to be lifted in and out of the aft door. A debarkation ramp for crew folded down from the port side, abaft the port main landing gear.

Armament comprised a single dorsal turret, containing a standard launch tube, an autoloader and a dual-mode laser. Both weapons were operated from the gunner's station, located immediately abaft of the crew common area. The turret had a dedicated magazine containing up to 13 reloads, either space combat missiles, planetary strike missiles, or remote mine delivery vehicles. This magazine could be reloaded through hatches in the roof of the main hanger.
