The Port Justin Military Base was a large base built by the Military of Jill during the later years of Floyd War I. On September 15, 1900, the base was bombed by the Northern Territory, causing the base to collapse around midday.

It was designed to train up to 2,000 soldiers every year. Elevated over a dry spot in the JAR River, it was the largest boardwalk in the country after it was completed. It also held 15 anti-aircraft missiles and two large tanks.
