In January of 117PA, Thron Ironbender, a technician at S-Mart, was experimenting with lightening an RFFC-17 by removing the heavy barrel cooling system, and installing an ISC-2 cooling system behind and above the barrel assembly instead. This gave more room to install a full second row of electromagnetic accelerators - while still keeping the weight well below that of the RFFC-17! He had much trouble in gaining assistance from the corporate heads, but still soldiered on and developed a new, MUCH improved RFFC.
The new hybrid weapon was still classified as an RFFC, although highly boosted in performance. It's ammunition is a specially developed armor piercing 20 mm cannon shell, with metal rings around the tip, mid section, and aft end of the shell itself. It fires a pair of these shells, one a microsecond after the first, using conventional propellants in a shell casing, and then further accelerates them through the barrel via electromagnetic accelerators - dramatically increasing damage and range capabilities from a standard cannon. The new design of RFFC was superior to it's predecessor the RFFC-17 on almost all counts. It had a better range, more penetration value, and most importantly a drastically reduced weight from the replacement of the heavy barrel cooling system
The corporate department of S-Mart was shocked by this incredible increase in performance, for a sacrifice of nothing at all, in the design - and so immediate testing, and plans were made to put the RFFC-19 into production. The first RFFC-19s entered service with the N.O.M.A.D. Military of Desert Star in October of 117PA, and by February of 118PA had completely replaced the RFFC-17 in the N.O.M.A.D. Arsenal.
When the news of the RFFC-19 broke out, Wa-Daisho made plans to purchase this weapon in numbers to replace their own RFFC-17s and the modified version of the RFFC-17 they have produced locally. Shockingly, King Ace Ripley himself made the declaration that the new RFFC-19 would NOT be shared with any of the Allied Nations, and would be retained exclusively for the defense of Desert Star, in the service of the N.O.M.A.D.
