Made as specialized tugboats to rescue damaged starships, GRZ-6B Wreckers are built by many ship construction yards and are often used in their own operations. A common sight in every corner of space for decades, someone always seems to find a new use for these versatile little craft, with the highest concentrations being along shipping lanes and near dangerous areas of space.
GRZ-6B Wreckers are equipped with a huge range of specialized equipment for use in deep space recovery operations; the most obvious being the pair of arm cranes extending from the front of the ship, used for everything from picking through wreckage to clamping hold of the hull for use in tugboat operations. Internal pump systems allow for the Wrecker to function as a self-manoeuvring fuel umbilical for capital ships, freighters and starfighters that have run out of fuel, provided that a tanker vessel is available. Similar pump systems connect to internal reservoirs of fire suppression chemicals for dealing with fires in areas of the ship that haven’t been exposed to vacuum.
Additional equipment is more utilitarian on the whole. Mounted on the forward hull is a variable output cutting laser that is used in conjunction with the arm cranes to cut apart the more unwieldy pieces of wreckage. On a lower setting, the laser functions as a welding tool for small jobs like patching micro-meteor hull breaches; the Wrecker typically carries a small number of spare hull plating for just this reason. Also included, for the sake of personnel aboard the stricken vessel, are compressed air tanks for restoring pressure to areas exposed to vacuum, though this is usually a stop-gap measure at best.
Because of the wide variety of tasks they are called upon to conduct, most Wrecker pilots have extensive training and experience in salvage and rescue operations. Most of these pilots wear the "Junker" nickname with pride, knowing full well the sight of their tiny ship jetting through space is a comfort like no other to professional spacers. Many a Junker has had a drink raised in their name in cantinas across the galaxy. In recognition of the need to preserve the pilots themselves against damage, the tiny vessel even includes an escape pod, typically marked with colourful graffiti such as "Queen of the Scrap Heap" or "Handle with care; Junker inside."
