Beyond the Stars
The Galactic Navy is the single largest fighting force in the galaxy. Comprised of crews from all species throughout the Federation, the size and scale of the largest capital ships in the Navy inspire awe in nearly all who see them. The Galactic Navy is the backbone of the military might of the Federation given physical form.
The Navy and the Army have a long-standing rivalry. “Navy flies, Army dies” is one crude way yeomen have been known talk about their Army brethren; more senior officers tend to feel similarly in spirit if not so directly. The tension is most evident when large-scale actions require the Army to use Naval transport instead of their own smaller transport ships. The Navy thinks that the Army tends to be uncouth and far too likely to take on unorthodox tactics with high rates of failure, making partnerships fraught at times.
The Navy is responsible for the security of space transport. As such, they are the primary agency against piracy and smuggling in the Federation. Naval patrols are regular sights around planets that are important lynchpins for galactic trade, and coordinated strikes with the Federal Justice Agency against remote smuggler bases are common.
