The Starstreak class was a class of freighters operated by the Interstellar Concordium in the late 23rd century. It was most famous for its usage of the subspace equaliscopic system, which allowed for energy-efficient jamming of subspace communication, at the cost of a bulky system. Units used as SES mounts were covered by solar panels. The turbolaser bank was located at the center of the junction of the engineering hull and the cargo hold.
