Aegis Solarum

The Aegis Solarum was the primary defense force of the Sol system.

The organization was established with the formation of the Union of Sol as a peacekeeping organization, and as a deterrent for possible extrasolar threats to humanity or the interests of the Union.

Initially, the Aegis Solarum was established alongside the Aegis Terrarum. The Aegis Solarum was responsible for defending the entire Sol system, while the Aegis Terrarum was responsible for guarding Earth and Luna specifically. In later years, the Aegis Terrarum was absorbed by the Aegis Solarum.

The Aegis Solarum became a cornerstone for the military of the Alliance of Systems alongside the Ancilican Voidia Royalis.

With the formation of the Allied Systems Federation, the Aegis Solarum was assigned as the permanent defense fleet for the Sol system. During this reorganisation, the Aegis Solarum negotiated favorable budget allocation and autonomous authority over the organisations activities. These demands became part of the Federation's Constitution, securing the survival of the organisation. Despite being a seperate organization under the directive of the Federation's ministry of defense, the Aegis Solarum contributed to the Federated Systems Navy where it could.

During the 23rd century, the Aegis Solarum used its autonomy and budget to secretly fortify the Sol system. A large number of advanced orbital defense platforms were deployed throughout the inner system on eccentric orbits so they were extra difficult to detect. These platforms were equipped with kinetic artillery and long-range railguns. The Aegis Solarum also installed modular weapon installations on both Terra Station and Helico Station. Another great investment was the modernisation of Earth's illegal nuclear arsenal, which also fell under the administration of the Aegis Solarum. These investments finally proved their worth during the Battle of Earth, where they were crucial in defeating the invading Vrox.

In the later half of the the 23rd century, the Aegis Solarum's actual defense fleet consisted mostly of Vishaap class, Caldius class, and Atlas class ships. After the ASF-K'adurbian War, this complement was shifted towards the Chasseur class, Pixides class, Nabulon class, and Sazara class. The fleet contributed greatly in the defense of the Sol system during the Vrox Rampage.

After the Battle of Earth it was obvious to the Allied Systems Federation that the Aegis Solarum had been siphoning military funding to further human interests for over a century, and that it used its great autonomy to do whatever it deemed necessary even if it was in violation of Federal and galactic law. After ousting Federation president Rotalia Laqo from office, the ASF Senate took direct control of the federations ministry of defense and forcefully altered the constitutional deal with the Aegis Solarum. This greatly diminished the organization's autonomy and funding. Various divisions of the Aegis Solarum decided to back the emerging Terran Unitary State because of this. The remaining assets of the Aegis Solarum continued to be responsible for the defense of the Sol system, but were now under far stricter management from the Federation government.
