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


During the Age of War, the company produced a number of notable vehicles including the Marsden I MBT[1] in 2396, the Büffel VII[2] in 2407, the Marsden II MBT[3] in 2463 and the Crossbow, the second home-grown Lyran produced BattleMech, in 2468. 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, which shut down 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 money from those lines, however, was able 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 for some decades yet, which the RetroTech 'Mechs seen as being ideal for organizations such as militia forces.[8]


Arcturan Arms has a manufacturing center on the following planets:


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