Planetary GeographyEdit

Kathil has three major landmasses, Hurste, Muran and Thespia. The planetary capital, District City, is located on Muran.[3] Also spanning the world are a series of oceans. The largest and most important of the continents is Muran, which is a continent with a variable climate; the western reaches of Muran are dominated by mountains and much of the continent is arid plains, with the more temperate regions located to the east and north. Only these temperate regions on Muran are capable of supporting agriculture, leaving the planet reliant on Hurste for the production of the vast majority of the planet's food. While Hurste is Kathil's breadbasket, there is nowhere on Kathil where agriculture is easy; the arid regions can only be farmed with assistance from widespread irrigation, and the plant life on Kathil is notoriously lacking in chlorophyll. The least hospitable of the three continents, Thespia, is dominated by mountains and deserts and provides ores for use in manufacturing industries around the world.[2]

Planetary HistoryEdit

Early HistoryEdit

Prior to the Reunification War, Kathil was an unremarkable and insigificant world. Possessed of a few deposits of rare metals that attracted a trickle of colonists, Kathil only became a world of import when the Star League Defense Force identified a clear requirement to have facilities located closer to the front than the borders of the Terran Hegemony for the repair and refit of naval vessels engaged in the various campaigns against the Periphery states. Having identified this capability gap, the Star League constructed a number of major shipyards outside Hegemony space, branding them Star League Naval Repair and Refit Facilities; Kathil was chosen to host one of these facilities, due to the Kathil system being remarkably free of dust and asteroids, reducing the risk of damage, particularly to fragile JumpShips. The resulting facilities in the Kathil system were officially christened the James McKenna Shipyards in 2602.[1] The shipyards were powered by a mix of energy transmitted up from massive solar arrays on the planet via microwave and local fusion reactors.[2]

The James McKenna Shipyards consisted of two discrete complexes; the first, a huge complex of repair docks and machine shops used to support JumpShips, was constructed in orbit near the zenith jump point. The second facility was a series of repair bays stationed in orbit and designed to support DropShips. The logistical chain supporting these two facilities included a complex of warehouses and repair industries located on the surface of Galax, and during the Star League era the shipyards would service vessels from the navies of the Star League, the Federated Suns navy and the Capellan Confederation navy as well as ships operated by private trading companies.[1]

By the height of the Star League Kathil was the location of a significant percentage of the Federated Suns heavy naval manufacturing industry; by 2765 with the massive manufacturing facilities at Galax yet to come online, Kathil and the worlds of Delavan, Layover and Panpour were responsible for ninety percent of all large naval craft manufactured inside the Federated Suns. Kathil was also home to a significant proportion of the defense manufacturing that supplied the Armed Forces of the Federated Suns. While the overall manufacturing base of the Federated Suns was highly dispersed and diversified, a core group of worlds - New Avalon, Crofton, Kathil, Panpour, Salem and Talcott - supplied move than half of all the equipment used by the AFFS.[46]

The Succession WarsEdit

Kathil was an inevitable target for the CCAF during the early Succession Wars, and despite dogged resistance from Federated Suns WarShips the JumpShip yards were crippled by Capellan WarShips. Subsequent Capellan attacks repeatedly reduced the abiity of the yards to function, and while repairs had been conducted that allowed the yards to at least perform routine maintenance and a limited number of major overhauls by the end of the Third Succession War the combination of battle damage and lost technical knowledge had resulted in most of the JumpShip yards remaining empty and unused.[1]

The DropShip yards managed to survive the first three Succession Wars in better shape than the JumpShip yards, and by 3025 the Galax facilities represented the largest and best-kept DropShip repair facility to be found anywhere in the Federated Suns. The bulk of the warehouses and supporting industries on Galax had long since been destroyed, however, and many of the spare parts that remained in storage on the planet after repeated raids had effectively become lostech, as the knowledge to identify what the parts were and their function had been lost.[1]

During the Succession Wars Kathil was the home of the Capellan Dragoons, a private army belonging to the Duke of Kathil; many of the members of the Dragoons were defectors from the CCAF, and their knowledge of the Capellan military often gave the Dragoons a clear advantage in combat. The Dragoons fought valiantly against the CCAF during the Second Succession War, but in the early thirty-first century the Duke of Kathil found himself impoverished by mounting debts. The Duke decided to sell the Dragoons to the AFFS, in exchange for a sizeable amount of money and with the added proviso that should he or his descendants accumulate enough funds to be able to buy back the Dragoons, the AFFS would allow them to do so.[47]

Despite the damage inflicted on the planet the large General Motors plant continued to manufacture materiel from it's location near District City, the planetary capital.[1]

After the Fourth Succession War General Motors and Universal Air entered into a partnership with Federated-Boeing Interstellar to completely refurbish the McKenna shipyards.[48] The three companies created a consortium, Kathil Shipworks, co-owned by the three companies and the Davion family, and extensively refurbished the shipyards; repairing the zenith station alone took several years, while the orbital docks wouldn't be online until 3039. Once back online, the shipyards were capable of constructing K-F Drives for the first time since the beginning of the Third Succession War, and the production capabilities of the shipyards steadily increased in secret until the facility was capable of manufacturing WarShips.[49]

With the unveiling of the first Avalon-class WarShip, the secret expansion in production at Kathil effectively became an open secret.[49]

FedCom Civil WarEdit

While increasing police actions and escalating raids had been ongoing during 3061 between various factions within the Federated Commonwealth, the Battle for Kathil which began on November 16th,[50] 3062 was generally acknowledged as the flashpoint for the FedCom Civil War.[51] Fortunately, the spacedocks were left undamaged after the civil war and remained in continuous operation, although civilian vessels faced a wait of twelve to eighteen months for a major service with longer delays for more significant repair work[2] due to the large number of ships already waiting for repairs following the War.[49]

Universities on Kathil had a good reputation in the 3050s and presumably the 3060s; a survey conducted by the New Avalon post in 3059 highlighted that the University of Kathil was ranked fourth out of all of the surveyed universities in terms of student satisfaction, and that the Federated Technical College of Kathil was considered the best party school to be found in the Federated Suns.[51]

The JihadEdit

During the Jihad, as Capellan March and Capellan Confederation forces battled as a result of Operation SOVEREIGN JUSTICE and Operation THUNDERSTRIKE, the Capellans struck at the shipyards in orbit above Kathil, using Death Commandos to cripple the facility during the first two weeks of May 3069. Regular Capellan forces then struck at Kathil during the last two weeks of May as part of a campaign of raids leapfrogging from world to world en route to New Syrtis.[52]

The Word of Blake took advantage of the Capellan attacks on Kathil to launch their own assault on the system. The Blakist forces launched biological, chemical and nuclear weapons at the planet, but despite the massive casualties inflicted on the population reports indicated that a number of inbound attacks were successfully intercepted by AFFS AeroSpace Fighters. The Word forces successfully destroyed the shipyards and captured the remaining jump-capable vessels in the system.[52] The General Motors industrial factory complex on Kathil also took heavy damage, and as late as 3081 was still operating as little more than a single-line tank manufacturing plant.[53]

With the main General Motors facility in District City offline, the smaller GM plant in Nugent on Muran was lucky to escape destruction and was able to produce Combat Vehicles continuously again by 3079, although estimates suggested that the District City would be offline until the 3090s.[3] GM's survival as a company was heavily dependent on direct funding from the Federated Suns government on New Avalon at this point, and Princess Regent Yvonne Steiner-Davion used this leverage to redirect the rebuilding efforts undertaken by the company. Where GM had been making the rebuilding of the BattleMech production lines on Kathil their highest priority, the Princess Regent instead instructed the company to diversify, placing more emphasis on the construction of assault tanks and battle armor.[54]

While the McKenna shipyards operated by Universal Air were completely destroyed by the Blakists, the JumpShip manufacturing facility at the Nadir JumpPoint escaped total destruction. The damage inflicted on the two facilities bankrupted the company, who sold the remaining assets to Federated-Boeing, and by 3079 Federated-Boeing had the Nadir yards capable of repairing Invader-class JumpShips, although estimates said that it would be years before the shipyards were actually manufacturing Invaders again.[55]
