The Nihon Imperial Naval Force (or often called Nihon Imperial Navy (大日本帝国海軍 Dai Nippon Teikoku Kaigun) is the navy branch of the Nihon Imperial Armed Forces, responsible mostly for naval operations in space and in the ocean. It roles mostly ship-to-ship combat, orbital bombardment, and deployment of starfighters, as well as the delivery of the army to combat. It is controlled by the Imperial Joint Chiefs which is nominally subordinate to the Emperor of Nihon as supreme commander of the army and the navy.

History Edit

Founded in 2043, the Imperial Navy was previously a part of HALO's navy operating in the Japanese archipelago, under the government of Amenria. Shortly after the Empire gained independence from Amenria, the navy changed its name to Nihon Imperial Naval Force and serve the Empire of Nihon.

The Navy partnered with Kawasaki Shipbuilding, Mitsubishi Heavy Industries, and STARK Industries, as well as deriving Calvarian technologies. In order to combat lot of superior nations, the NINF devoted large amounts of resources to creating a force superior in quality and quantity.

Assets Edit


Infantry Edit

Navy personnel uses HW-395 rifle and P6 series handguns.


The primary offensive weapon of all NINF carrier ships is the Magnetic Accelerated Cannon. These weapons are massive coil guns that are used to accelerate projectiles ranging in mass from 600 tons in the case of smaller warships,and 3,000 tons in the case of Super MAC platforms.

Almost all NINF warships are equipped with Enenra missile pods for ship-to-ship engagements, which prove mostly effective against unshielded targets. In addition, the NINF also mounted 50mm auto-cannons on its ships to defense against enemy fighters and boarding craft, controlled by shipboard AIs.

NINF warships also carry significant Marine detachments for internal security, boarding actions, and planetary assault, and carry all the equipments needed by Marine forces. It is implied that a significant portion of the interior of NINF warships are devoted to this purpose, as there are armories and barracks that hold these supplies.

Ships of the NINF also carry a number of MF-1 Odachi-class Interceptor. These are armed with 110mm Rotary cannons and Basan Missiles, and sometimes a space mine system or even a single Kiun-II Nuclear Missile. They can also be remotely-operated and used to carry a remotely-detonated Kiun missile, which, when detonated, effectively destroys both the Odachi and its selected target.
