 ====== Swallow Freighter (140dt) ======

+{{ :traveller:spacecraft:tl9:swallow.png?nolink&250|}}
 Late TL 9 freighter with experimental plasma drive. The crew quarters are placed as far from the drives as possible, to reduce the radiation hazard. The hull itself is very light, and easily damaged by micrometeorites. It's total length is 40m, though much of this is the thin neck. The main bulk of the ship is 9m wide.

 The Swallow was one civilian design which tried to make use of the early plasma drive designs to allow fast orbital insertion and escape. Compared craft such as the Albatross, it could simply point away from the planet and thrust. In order to achieve this though, the Swallow sacrifices maximum speed and also durability - the design is stripped down to the bare essentials in order to reduce mass to a minimum.
