The Tobruk class Interface Interceptor is a combatant smallcraft.

Description (Specifications)[edit]

The Tobruk-class Interface Interceptor is a relatively low-tech design notable for using a gravitic drive for thrust rather than the more common jets-and-rocket approach. Its only weapon is a laser of the sort used on spacecraft and its sensor suite lets it engage targets quite far away. Multiple squadrons of cooperating Tobruks can take a significant toll on an invasion force, especially one already engaged with SDBs, fighters, and orbital stations.

The Tobruk is designed with atmospheric skipping very much in mind, with a relatively broad wingspan. Ideally a Tobruk will remain in space as long as practical, extending its fuel endurance by powering up its grav drive only to maintain speed, and engaging targets as they rise above the horizon. In practice a competent and determined invader is likely to eliminate most or all interceptors, leading to a “magnificent forlorn hope” mentality among their pilots.

History & Background (Dossier)[edit]

Interface Interceptors are specialized defensive craft employed by worlds' COACC forces. They are aircraft, using lifting surfaces rather than gravitic lift, but they are intended to engage their targets in space as Spaceplanes. The characteristic mission profile of interface interceptors is to boost just out of the atmosphere at suborbital speed, where they engage hostile spacecraft. Many designs are meant to skip over the upper atmosphere instead of following pure ballistic courses, thus increasing their engagement duration. Since they are not intended to reach orbital speed, reentry is a relatively minor concern, putting little additional stress on the airframe.

As is often the case with specialized weapon systems there is much dispute over the practical value of interface interceptors. Many COACC commanders dismiss them as “neither fish nor fowl” that lack the space capability of SDBs and small craft and are less than ideal for engaging hostile craft within the atmosphere. Adherents point out that interface interceptors provide as much firepower as equal numbers of light fighters, and that their ability to suddenly rise above the horizon inhibits enemy target locks while the interceptors can benefit from local sensor nets. Almost the only point of agreement among such officers is that interface interceptors can be built and used almost as soon as a world can reach space, as indicated by the venerated Terran “Dyna-Soar” design.
