Alliance Navy

The Alliance Navy is the branch of the Systems Alliance military responsible for naval operations. The Alliance Marines, the ground operations branch of the Alliance military, are a specialized branch of the Navy.

The Alliance Navy is one of the greater naval forces in Citadel space, rivalling that of the turians. Its military prowess has drawn the attention of the Citadel Council. While the Council is concerned about the possible outcome of another war between humans and turians, they are also keen to harness the Alliance Navy's peacekeeping potential, especially in unstable regions like the Skyllian Verge and the Attican Traverse. The Navy also makes humans an attractive prospect as the newest Council species.

Doctrine
The Navy is a space combat force primarily charged with protecting human colonies, space stations, and mass relays. While the Navy stations weak garrisons to guard Alliance colonies, its strength is centered upon powerful fleets stationed at mass relay nexuses that can rapidly respond to any colony under attack.

Composition
The Alliance Navy possesses over two hundred vessels, including six dreadnoughts and at least one carrier. Its individual vessels range considerably in size and firepower, varying from hundred-meter-long frigates to nearly kilometer-long dreadnoughts. Fleet units are also supported by fighters and dedicated interceptors.

The Alliance Navy was instrumental in saving the Citadel when the station came under attack by Sovereign and Saren's geth. With the Citadel Fleet cut off by the locked-down mass relays and under heavy fire, the Alliance Navy was the only force large enough to provide reinforcements. Depending on Commander Shepard's orders, the Fleet either suffered heavy losses saving the Destiny Ascension, or abandoned the flagship in order to attack Sovereign.

Regardless, as mentioned in Mass Effect: Ascension, the devastation of the Citadel Fleet meant the Alliance Navy was left as one of the most powerful unified military forces among the Citadel races. This fact alone meant humanity's place in galactic society was assured. (See Talk page.)
