Thanks guys! - you put me back on the right track
I've worked quite a bit with tha_Rami's Evoverse History in the past but had a major Yoda moment, vaguely remembering having read about someone inventing gate technology but not that it was a special type of gate . . . .
. . . . it seems that a year after the first probing attacks on naval vessels by the Vonari and their abortive attempt to invade Earth one "Dr Adam Sheford" managed to create a gate (in 2288) that allowed travel to any point in space rather than another "receiving" gate. (Prior to this carriers had to use established gates or C5 Fulcrum drives.)
This prototype "Shefeld" gate was located in Rucker. It was used by the Special Operations Carrier carrying the 80th Wraith Squadron to jump between Rucker and Sol in a single jump arriving just in time to turn the tide in the Vonari attempt to destroy Earth. Soon after, the "gate" technology was refined and reduced in size so that it could be carried by and powered by capital ships, giving the navy their own long range jump drives. (actual jump limit is a military secret)
And a good job too, because more recent Carriers and Battlecruisers are too large to fit through standard gates!
The self contained idea works very well for me!
