Arcturan Arms was a military hardware manufacturer based on Arcturus, the former capital of the Lyran Commonwealth.


During the Age of War, Arcturan Arms produced a number of notable vehicles including the Marsden I MBT in 2396,[1] the Büffel VII in 2407,[2] and the Marsden II MBT in 2463.[3] The company also manufactured the second homegrown Lyran-produced BattleMech, the Crossbow, in 2468.[4] Despite these achievements, the company's fortunes suffered when the Lyran Commonwealth shifted its capital from Arcturus to Tharkad, forcing it to shut down its factory in 2490 after producing only a few hundred Crossbows. MacEnroe Motors bought out the financially troubled company in 2541 and would later discontinue Crossbow production in 2550.[4]

During the Jihad, Arcturan Arms expanded its refit facility to produce RetroTech 'Mechs for the LCAF. Production on these lines had shut down by 3079,[5] but the profit money from those lines was used to launch new Marsden II production facilities on Buena[6] and Halfway.[7] In September 3081 Arcturan Arms told the Interstellar News Network that their refit facilities would be producing considerable numbers of the primitive Archer, Commando, and Dervish 'Mechs for some decades yet; RetroTech 'Mechs seen as being ideal for low-level organizations such as militia forces.[8]


Arcturan Arms has a manufacturing center on the following planets:


The facility on Arcturus suffered no capital and personnel losses, but the operating capacity of the factory was reduced to 40% of their main output in 3079.[9]
