Barrier Patrol Corvette
The Barrier Patrol Corvette is a smaller relative of the Barricade Patrol Cruiser. The Barrier was originally developed as an engineering study model for the technologies that would later be included in the Barricade. As such the Barrier Patrol Corvettes were the first Tholian ships to mount the MK-2 model web spinner. The success of the Barrier during early trials encouraged further construction on the class and it quickly entered widespread use in the Tholian fleet.

Whereas the Barricade was designed to function as an all-around fighting ship, the Barrier was instead designed as a very predatory design intended for engaging enemy cruisers. Groups of two to five Barriers would descend on unwitting alien cruisers in hopes of disabling them. If forced off the ships could then begin laying a Tholian web to ensnare the ship. Although most enemy vessels would likely escape before the web could be completed, it could buy the Tholians enough time for other, larger ships to arrive on the scene.

The Barrier remained in service beyond the phasing out of the Barricade, in large part due to the former’s heavier firepower. The number of Barriers in active duty slowly fell until the last ship was mothballed in 2325.
