Based on smaller rapid assault ships, the BT-7 Thunderclap was originally developed during the war for fast deployment under fire. That revised design was outfitted for Republic Special Forces

with a streamlined hull, prototype armor plating and flexible bulkheads designed to absorb heavy impacts.
The Thunderclap's main deck featured a command center, secure armory, fully outfitted medical bay and briefing room. Provisions were made for squad comfort with a spacious bunk room and recreational facilities. The upper deck housed the bridge and navigation computer, and could be sealed by heavy pressure doors in an emergency.
For armaments, the Thunderclap had one primary and two secondary heavy laser cannons. It was also armed with two anti-personnel support rotating repeater cannons mounted above the main entry ramp used during rapid squad deployments, and two anti-air defense cannons on top of the pilot cabin. State-of-the-art tactical computers and targeting systems ensured every shot counts.
Although the ship's design was intended to deflect blaster fire away from the main compartments, modular shield systems ensured few attacks get that close.
