Description/Overview:
         (SHF-01 HEAVY SPACE FRIGATE)
         The SHF-01 heavy space frigate was the second omni-hull warship frame type built by the USR.  It was built using the exact same hull as the HSD-01 except that some areas were enlarged and more weapons were added, thus increasing the tonnage of the ship.
         The SHF-01 uses one cluster of twenty Gaea Energy GE-5000 fusion reactors on each side of the ship, one cluster of twenty-two at the rear.  The side clusters provide the power for both the high yield ion engines and the stellar warp drive units.  The single aft cluster was located in the central-aft below of the ship below the hangar deck and was used to power all of the other systems of the ship.
         The Prodono-Technologies (ProdonoTech) SWD-3420 stellar warp drives were also used in the SHF-01, but the maximum speed was reduced to .276 light years per hour due to the increased tonnage of the ship.  This drop in FTL speed was considered insignificant, as the distances between star-systems within the local group of stars around Sol/Alpha Centauri were less than 100 light years apart in most cases.
         The sublight engines of the heavy space frigate were the same as those used on the HSD-01.  The pair of Eurospace ES-ID-18,000 ion drives had a reduced speed of 138,320 mph/Mach 182 maximum each engine and 276,640 mph/Mach 364 combined.  This speed was still considered adequate for both general and combat operations.
         Two additional Centauri Research CR-PC-3252 dual 325-megawatt PHELAC turrets were added to the SHF-01, bringing the total to 5 cannons and increasing the firepower of the basic frame considerably.  This allowed the heavy frigate to go head-to-head with the Solar Empire’s capital ships up to the Harpy class heavy cruiser.
         Three additional USR-ST-800 space torpedo launchers were installed.  This additional firepower was useful at close range and against hardened targets like space stations, planetoid installations, and planetary bases, but not very useful against other ships of its era.
         The mobile weapons complement of the SHF-01 was bolstered by the addition of 20 BK-01L BattleKnights along with the original 20 SF-03A space torpedo-fighter/bombers. This gave the heavy space frigate both long-range and close-range mobile weapons support and increased the effectiveness of the vessel overall.
         The defense systems of the SHF-01 were upgraded from the six PR-DF-1100 deflector field generators of the HSD-01 to six Centauri Research CR-DF-1600 1600-megawatt deflector field generators.  These generators provided ample protection for the ship against nearly all types of beam weaponry in common use during the 1st Interplanetary War and the few years afterwards.
         Some 400 of this class were built before 2178 AD.  Of those, all were either destroyed, gone to Alpha Centauri, or in the hands of the Grand Duchy of Ceres.  The number of SHF-01s built after 2178 AD is unknown, although estimates range from around 2500 to 5000 ships built by 2210 AD.
