A rather elderly freighter model, the D-400 is a well beloved
craft among spacers. Built shortly before hyperdrives reached
their current levels of efficiency, the Charger was equipped with
the huge power pants required to push the hyperdrive past light
speed. When it's drive is replaced with a fully efficient modern
hyperdrive, those power plants are easily converted to increasing
the shield power or adding on other weapon systems. The Charger
never sold as well as many other light freighters due to it's
high cost, and it's inefficient hyperdrive, and therefore, not many
were produced. Those that have survived are sought after for their
durability and power, and can command prices much higher than the
"book value" depending on their condition and modifications.
