The Crossfiled Class was named for Albert Scott Crossfield, a test pilot and aeronautical Engineer. Albert Crossfield lived from 1921 to 2006, he was a fighter pilot during the Second World War and would go on to fly fourteen test flights as part of the X-15 test program. In 1986 he was part of the task group that investigated the destruction of the NASA Shuttle Orbiter Challenger after it exploded during take off .73 seconds after take off.
The Crossfiled Class follows the standard the Primary and Secondary hull with two nacelles. The Primary hull of the Crossfiled calls differed from other Starfleet ships in that the Primary hull consisted of three separate sections. These sections are a central sphere surrounded by two ring sections with cross over bridges connecting the inner and outer rings. The secondary hull housed the ships engineering section and shuttle bay and was designed as a flattened triangle with the nacelles held at the same level of the secondary hull.
The unique design of the primary hull resulted in two ships of this class, the USS Discovery and USS Glenn were chosen in the early 2250’s to test an experimental new form of faster than light propulsion known as the Spore Drive. To facilitate the use of the Spore drive the Dorsal surfaces of the rings were modified so that they rotated in opposite directions to initiate excess energy cavitation. During this testing the Glenn was lost due to an accident during testing of the spore drive. Eventually the Spore Drive program was closed due shortcomings in the current level of computing power and ethical questions centered around the need of an organism to over come those shortcomings. Like all other ships in the fleet the majority of ship of the Crossfield class was utilized standard warp drive for faster than light propulsion.
As science vessels the Crossfield ships of this class were often tasked with missions of research and investigations. Each ship of the Crossfield class can support up to three hundred different scientific investigations. This allows these ships to support long term research projects.
