Imperial Japanese Navy
The doctrine of the Imperial Navy is uncompromisingly based on carrier warfare. Any hostile forces will be destroyed by long-range strikes from the Akagi class carriers. The duty of the rest of the Fleet is to protect the carriers while they carry out this mission. In fact, the Japanese research and development effort is so focused on this goal, no energy-based weapons have been developed beyond gauss cannons that are used for close-in missile defence.
The two Akagis are 18,000 ton ships, each with a strikegroup of eighteen A7M Zero fighters and a single Nakajima C6N Saiun scout. They are unarmed, relying on their Agano and Sendai class escorts for protection. Some Japanese military analysts have criticised the design for its limited armour protection and short range, especially considering the fuel demands of the fighters. However, this was the maximum hull size permitted by the available shipyards so the Japanese designers concentrated on the largest possible strikegroup.

The A7M Zero, named after its illustrious predecessor from over 150 years ago, is the backbone of Japanese strike power. With each Zero capable of launching three missiles, a full strike from both carriers would create a wave of over one hundred Type 100 anti-ship missiles. Although primarily relying on the active sensors of the Saiun class scout during its attack, the Zero does possess its own backup active sensor with a range of three million kilometres.

The Saiun class scout has two missions. While its primary function is to provide sensor coverage for a strikegroup of Zeroes, it is also designed to operate as an independent, long-range scout.

The Agano class light cruiser is the first line of defence against hostile missile attack. With fifteen launchers, over four hundred Type 101 anti-missile missiles and electronic systems capable of detecting and tracking incoming missiles at almost a million kilometres, the Agano class is intended to provide a protective umbrella for the Carrier Striking Forces. Four are currently in service, with Agano and Noshiro assigned to protect the Akagi, while Sakawa and Yahagi protect the Kaga.

The Sendai class light cruiser provides point-blank missile defence for the Carrier Striking Forces, destroying any hostile missiles that penetrate the defensive shield of the Aganos. Each Sendai is armed with two triple gauss cannon turrets, each with its own dedicated fire control system. With a single turret capable of firing nine rounds every five seconds, the two Sendais assigned to defend each carrier can create substantial weight of defensive fire. The Sendai is not intended to operate alone as its only sensor is the OPS-37 Missile Detection Sensor, which has a maximum range of three million kilometres. This compromise was necessary in order to accommodate both turrets and their associated fire controls without sacrificing speed or armour protection. There are four Sendais in service. Jintsu and Kako operate with the Akagi in the First Carrier Striking Force. Naka and Sendai form part of the Second Carrier Striking Force and protect the Kaga.

Katsuriki and her sister ship Komahashi are newly built geological survey vessels. With specially designed fuel efficient engines, spacious crew accommodation, and large engineering decks, they are intended to operate far from home for extended periods. Because this makes them vulnerable to attack, they are armed with twenty-four launch rails identical to those developed for the Zero. While this is still a limited offensive capability and would be ineffective against a significant enemy force, it may be enough to destroy or cripple a single opponent, or at least launch a defiant last ditch attack.
