VCX-820 escort freighter

The VCX-820 Escort Freighter was designed a few years before the Yuuzhan Vong invasion. It was a heavy, but fast, "flying guns"-platform. With its 8 autoblasters, it could easly guard convoys of otherwise defenseless bulk freighters and commerce craft. Designed with military requirements, it was nonetheless reasonably priced on the civil market. Originally, the VCX-820 was designed for the Imperial Remnant, but invasion by the Yuuzhan Vong caused many smugglers and private traders to seek out a vessel that would allow for protected travel through profitable, yet highly dangerous, space lanes. As a result of this desire, many larger trade-firms invested in these vessels, making it quite common during the hard times of the New Republic.
