Amundsen is the Earth Union’s northernmost port facility in the Western hemisphere, and forms the “upper half” of the naval defense grid around the general headquarters at JOSH-A. The base is positioned not far from Kugluktuk on the coast of Coronation Bay, and is one of the few positions with direct access to the Arctic Ocean at that altitude that doesn’t suffer from freezing during the winter months.

The base occupies a stretch of the barren coast south of Victoria Island, with large-scale dredging undertaken by the Earth Sphere Alliance to permit the construction of submarine pens and allow high displacement vessels to pull up to the docks. Given the consistently poor weather, no airfield was built, and defense of the base was given over entirely to land-based mobile suits. Since the adoption of GN-powered mobile weapons by the Earth Union this has been remedied – garrisoned mobile suits are stored in the former submarine docks, which have been modified with the addition of a vertical launch shaft and several turreted beam cannons. Unlike many Union bases, including a number of former Alliance installations, the Amundsen facility does not feature concealed defensive emplacements due to the impossibility of building the sturdy blockhouses below ground where the turrets are usually stored – the soil is simply too loose during summer or frozen solid during winter. Instead, the weapons are mounted in sturdy beam ablative-coated turrets that are primarily placed atop base structures to present a higher angle of attack and greater overall coverage.

The base layout takes the rough form of a semicircle, with the flat portion consisting of the dock facility and mobile suit hangars on the seaside. Defense coordination is carried out in a command center below a U-shaped administrative building in the northern terminus of the main concourse, while a low hill to the south presents several large antenna arrays and scanners in dome-like fixtures to provide long-range threat detection. The old mobile suit hangars are now used for storage of dry goods, and a fueling center for ships has been replaced with a facility for recharging GN drives via several large compressed particle tanks that lie in heavy revetments against the former submarine pens.
