Ship Class: Independent League Drones
The First Pan-Galactic War proved the concept of League Drones was a solid one. They had obliterated the older asari fighters, and been evenly matched against salarian stealth units. However, against turian heavy fighters, the drones had proven to be lackluster. Their short range energy torpedoes were simply outperformed by the turian's Thranx weapons, and their armor and barriers were weak compared to turian fighters. The use of stealth technology had also proven problematic for the drones somewhat limited on-board sensors, and several new classes of drones were created to fill these gaps.
Tai-Chi Anti-fighter drone
Armed with long range mass accelerators, the Tai-Chi was designed to be much faster than any heavy turian fighter, and be able to stay out of Gladus' effective engagement envelope while harassing the enemy. If the enemy closed, the Tai-Chi would switch to on board laser mounts, which could cut through kinetic barriers and cripple the enemy. Tai-Chi's were designed to be deployed in swarms of eight, controlled be a single operator and simple VI. The drones would provide a screen for the League's sensor drones and heavy bomber drones while picking off light units. Like most League drones, the Tai-Chi was limited to space combat, and was ineffective in atmosphere.
Ress'Nvar sensor drones
The introduction of true stealth systems greatly altered the dynamics of inter-stellar warfare. Whereas before a simple sensor net was capable of detecting enemy ships from extreme range, stealth ships could slip past all but the most tightly monitored lines. The realization that vital capital ships could be exterminated before their screens could destroy the enemy or they could rabbit to FTL to escape danger meant that a much more powerful sensor platform was needed. Thus, the Ress'Nvar (khelish for "Perceptive Palm Method" an ancient martial art) was created as a dedicated long-range sensor platform. The drones would form a sensor web around fleets, giving them enough time to flee or redirect their screen to intercept the enemy.
Ress'Nvar drones were outfitted with revolutionary element zero detectors, that were able to locate the mass effect fields emitted by eezo cores of all warships, which were able to burn through the stealth of any enemy ships. This capability was a closely guarded secret, and until the opening days of the Second Pan Galactic War, most commanders actually thought that their drones were only outfitted with advanced LADAR and heat detection. The largest drawback of the eezo detector was that it was only effective at long ranges of the eezo core was engaged, and a ship on a ballistic setting could slip by the sensors. However, their powerful LADAR was able to lessen this flaw, though active LADAR did clearly show the location of the drones, unlike the passive eezo scanners.
Laarvek heavy bomber drone
The effectiveness of the EGGLAYER nuclear launchers against larger ships was proven beyond a doubt in the Battle of Pildea Station and in the Battle of Harsa, where the nuclear warheads devastated enemy cruisers and capital ships, along with fixed defenses. However, against turian fighters the nuclear weapons proved to be a case of overkill: though the launchers could obliterate enemy fighters, the single use nature of the launchers meant that the enemy could simply swarm the drones with fighters, leaving them without an effective means of attacking the enemies capital ships. As part of the solution to this problem, dedicated anti-fighter drones were created, along with the Laarvek (named after a form of krogan ritual combat). Armed only with EGGLAYER systems, the Laarvek was outfitted with heavier shields and armor to allow it to strike deep into the heart of the enemies fleet and deliver its nuclear payload. Against enemy light craft, the Laarvek could still use it's EGGLAYERs to take out the enemy, though ideally the Tai-Chi drones would act in that role.
Sambo aerospace drones
The long drawn out action in the Kites Nest following the First Pan-Galactic war showed that the League's reliance on kinetic strikes to provide air support was simply not sufficient for every situation. Close air support was needed, and League carriers or hangar bays were going to be the best way to deliver that. To provide that close air support, the Sambo drones were developed. Able to function in most atmospheres as well as vacuum the Sambo's were smaller and slower than other drones models, and typically ineffective against other spacecraft. However, they were outfitted with high-powered mass accelerators and hell-fire rockets to use as anti-personnel or anti-vehicular weapons. The Sambo was also capable of landing on most flat surfaces, and could be refueled and rearmed by ground forces.
