Osean Maritime Defense Force

The Osean Maritime Defense Force, OMDF, is one of the world’s largest naval strike forces. Its only competitor is the Yuktobanian Maritime Force. The OMDF's 3rd Osean Naval Fleet has significance in the latter half of Ace Combat 5, as it is involved in the Battle of the Ceres Ocean, and needs to be escorted in one of Ace Combat Zero's missions. Most of the fleet was destroyed in the Circum-Pacific War due to Yuktobania's war submarine Scinfaxi and a surprise attack on the docks which they were resting on.

General Information
Osea introduced its newest ship, the OFS Kestrel, in 1995 during the Belkan War. Her captain during this war was Commander (later Captain) Weeker. This Nimitz Class supercarrier is able to carry more aircraft than earlier aircraft carriers. Osea still operates the F-14A Tomcat, F-14B Bombcat, F-14D Super Tomcat and is adding the F/A-18E Super Hornet,and F/A-18C Hornet to their fighter support squadrons.

There also are three other known carrier groups, those led by the Buzzard, the Vulture, and the Barbette. The latter three were totally wiped out in combat with the Yuktobanians (Vulture and Buzzard), and the Kestrel itself (Barbette).

During the Belkan War in 1995, in Operation Costner, the 66th AFU Galm defends the Osean 3rd Naval Fleet, along with the OFS Kestrel, from two flanking attacks by Belkan Air Force units. Although greatly outnumbered, the Osean fleet managed to pull through with minor damage. The Osean 3rd Naval Fleet was heading into the Osean Great Lakes area to provide aerial support for Osean and Allied ground forces.

Fifteen years after Operation Costner, the OFS Kestrel was again thrust into war when the Yuktobanian Air Force and Yuktobanian Maritime Force launched a surprise attack on Port St. Hewlett, an Osean naval base, both by air and sea. The 108th TFS Wardog was sent in to defend the Kestrel at any cost. Later in the war, the OMDF shipped a battalion from the Osean Marine Corps to the Bastok Peninsula in Yuktobania, where they made an amphibious assault.

On or around December 7, 2010, the Kestrel, as well as a number of other ships, probably from the 3rd Osean Naval Fleet, split from the OMDF and formed the Kestrel Fleet. The Kestrel Fleet knew that the Belkans, not the Yuktobanians, were the true enemy, and silently split from the OMDF to fight the Belkans. The carrier carried four mysterious fighters, known as the Ghosts of Razgriz, who were launched on various anti-Belkan missions.

Then, on December 29th 2010, during the Battle of the Ceres Ocean, an Osean carrier group lead by the Barbette, another OMDF carrier, stumbled upon a naval battle between a Yuktobanian fleet and the Kestrel Fleet. Since the Kestrel Fleet had "betrayed" Osea, the Barbette Carrier Group attacked. However, the entire battle group was destroyed by the enemy.
