These ungainly looking but rugged utility and liaison ships were used for transport of personnel and cargo in Alliance service after the Unification War, and are built just fast enough to run and just tough enough to handle pirates and small vessels. They were often deployed to support wings of ASREV's at remote frontier bases. The armament is substantial for such a small ship, though somewhat outdated and outclassed by more modern designs. They are not warships, but have been pressed into service as such on many occasions by all major factions in the recent chaos. In 2525, most 929-B's are getting pretty worn out, though they are still manufactured in a few places. The 929-B is unusual in that it has two pulse engines instead of a single large one; the designers intended this to increase fuel economy and reliability, but that didn't pan out. It does allow the ship to be refitted with engines taken from smaller vessels, which does allow for easier frontier maintenance at the cost of a more complex engineering setup. Atmospheric operations and VTOL landings are performed using the central aerospike engine and several smaller thrusters on the underbelly.
