Hammer & Junkers Class Starships

I've seen alot  Crusiers, Battlecrusiers, Scouts, Battleships and Carriers but I on the other hand got an new way of created tranports and tankers for the Federation. The Hammer and Junkers Class Starships could provide support, cargo and Deuterium for Federation ans Starfleet vessels who are is distress, damaged or ready for combat.
