The Ionian Navy is the Ionian League’s naval warfare force, responsible mostly for naval warfare and operations in space. The Ionian Navy is the largest branch of the Ionian Military, with over 500,000,000 active service personnel. Formed initially as a branch of the Ionian Army as a means to transport troops to battlefronts during the Ionian – Pagatharan War while also engaging in ship-to-ship combat with the Pagatharan Navy. The Ionian Navy steadily grew into a juggernaut it is today over a century of growth and expansion. The Ionian Navy is now the single largest branch of the Ionian Military and plays one of the largest defense roles in the Ionian League. 

The Ionian Navy’s transformation was the creation of Admiral Diokles Maheras during and after the Ionian – Pagatharan War. He forged the Ionian Planetary Navies into one large cohesive machine, in the image of the Old Ionian Navy during the height of the Aclyden War. 




Early Establishment and Aclyden War

When the Ionian League was founded in 3031, it was founded without a true standing navy. In the decades after the Leagues foundation its member worlds had relied on their own militaries, and were expected to contribute resources and troops to a centralized force if a threat presented itself. From the founding of the League till the Great Android revolt the motion of a centralized navy would not fade away into the roar of the parliament hall. It would not be until the start of the Aclyden War in 3150 that the Ionian League would establish a centralized military. According to navy tradition, the Ionian Navy was headquartered on Ossyria during the Aclyden War, the site of the Ionian League’s largest shipyard.

The early Ionian Navy suffered from a lack of a formalized command chain and poor logistics, however played a pivotal role in the course of the war; ferrying troops to the battlefront and keeping the space around Aclydes clear. However, by the end of the war the expenditure of keeping a centralized navy, coupled with the devastating losses in both manpower and equipment as well as the near-total destruction of Aclydes’ surface the Ionian Navy was disbanded in 3157.

Re-establishment and Ionian War

In the decades leading up to the Ionian War a militarist faction within the Ionian Parliament attempted to reform a centralized navy, however progress was slow. During the Trillian Crisis between 3314 and 3334 Admiral Arsen Chronis tried to portray the space forces of the Ossyria System Fleet as the legitimate Ionian navy, even referring to it as such.

A decade later, a centralized Ionian Navy would be reinstated after the Military Creation Act of 3336 shortly after the onset of the Ionian War. The Ionian Navy worked closely with the Ionian Army during the ensuing conflict, and absorbed the remaining system fleets following the Second Battle of Hyperion. The Ionian Navy would continue to act as the vanguard of the Ionian war effort across the Ionian Cluster, matching the Pagatharan Fleet ship for ship in a number of major engagements across the sector. The Ionian War produced some of the greatest known naval officers in Ionian history, such as Grand Admiral Diokles Maheras. By the wars end in 3345 and the signing of the Arsithos Concordance, the Ionian Navy had grown three fold its original size becoming the pan-ultimate power in the Ionian Cluster and the Cronus Rift.

Tensions in the Periphery

As of the 3400’s, tensions have begun to mount between the states of the Periphery of the Eastward Rim operating under the Peripherian League, and the ultra-zealous Empyrean See located to the leagues west. As a result of the political climate of the Eastward Rim, the Ionian League began to mobilize Navy battle-groups, deploying them to key systems within the Ionian League at different Ordnance/Regional Depots. The Ionian Navy’s far flung outposts at the edge of the Ionian Star Cluster had seen a complete refit and restaff in the years preceding, as well as the deployment of multiple defense-stations in systems along the Star Cluster’s trade routes.


Operating Forces

The Ionian Navy forces are divided into a number of expeditionary fleets. These tend to be large formations, though they seldom patrol together; single ships are commonly seen patrolling throughout Ionian space. These fleets are further divided into several battle groups, more common tactical formations which are formed on an as-needed basis and vary dramatically in size from three ships to large carrier groups. Battle groups are flexible fighting organizations that can be “plugged together” into arranged task forces. A squadron is a group of warships that is smaller than a fleet. Artificial intelligence administrators of the Navy carefully arranging the dwindling ship roles into attack, battle, carrier, monitor, and support squadrons. 

Shore Establishments

The Ionian Navy operate a number of planetary based establishments, from planetary defenses such as ground to space missiles, to orbital dry-docks and planetary defense stations. The Navy has its headquaters in Idithos, the planetary capital, adjacent to the Council Yard near the White Tower of Idithos. It is from here that the entirety of the Ionian Navy is controlled. The Navy also hold jurisdiction over the civilian stations operating within Ionian League territory, such as the Orbital Tethers and Merchant Stations. They also operate a number of short-range Ordnance/Regional Depots and short-range listening posts throughout the Ionian Star Cluster in the case of possible invasion.


Large numbers of men and women are employed by the Ionian Navy. Servicepeople hold ranks, which are divided between officers and enlisted. Ionian Navy personnel are given training in self-defense. Navy recruits serve in initial recruit training operated by the Unified Ionian Military Training Institution. There, recruits are trained, tested, and evaluated on their physical fitness, proficiency with firearms, and command potential. Following graduation from UIMTI, a naval recruit may be required to complete additional training revolving around the vacuum of space and microgravity. Finally, a recruit is assigned aboard a naval vessel or installation as a non-commissioned recruit within the Navy. Several Ionian colonies are home to Officer Candidate Schools that provide training and allows enlisted personnel or civilians to become officers. Renowned OCS academies include the Ossyria OCS Academy and the Diokles Academy of Military Science.


Ionian Marines

Main article – Ionian Naval Infantry Corps

The Ionian Marines are an specialized light infantry force of commandos, capable of deploying at short notice in support of the Ionian League’s military and diplomatic objectives. The Ionian Marines are organised into a highly mobile light infantry brigade and a number of separate units. The Corps operates in all environments and climates, though particular expertise and training is spent on naval warfare, expeditionary warfare and commitment to the Ionian League’s Rapid Reaction Force
