HsB-AD-CVA01

The, also known as the Fugaku (ふがく), is a next-generation aircraft cruiser developed by Academy City.

Principles
The Fugaku is 300m long, has a displacement total of 106,000 tons, and has a speed of around 50 knots. The ship is powered by a fluid dynamic power generator, supported by a diesel engine, with a 45,000 kW output. The fluid dynamic power generator uses the resistance of traveling through fluid (such as air or seawater) to generate energy, capable of harnessing immense power from the waves while effectively floating in the sea.

Touted as a revival of the as the world's most powerful warship and based on a design philosophy of "bigger is better", the Fugaku has extensive firepower and range, with 35cm guns, large cruise missiles and onboard aerial units.

The stern weaponry has been removed to provide room for its electromagnetic catapult, also allowing it to carry 40  (single-seat multipurpose stealth fighters, also known as Sharp Frames (シャープフレイム). The latest version of the Fugaku is also equipped with 200 laser attack units to fully neutralize enemy aircraft and missiles. It may also carry Snakehead self-destructing drones.

In addition to various armaments for attack and defense, both direct and indirect, the ship's anti-air radar and ballistic prediction supercomputer provide it with a strategic-level missile interception infrastructure, even when it is cut off from the central datalink (e.g. through an attack on land facilities, or high-level electronic warfare).

Background
Prior to the Fugaku's development, the aircraft cruiser classification had been out of style.

New Year's Arc
On January 4th, after being thwarted by Anna Kingsford and Aleister Crowley during her hunt for Anna Sprengel in the middle of Academy City under martial law, Mut Thebes came across the prototype Fugaku moored at the side of a canal in School District 6. After reading the ship's displayed specs, she decided to make use of it and absorbed multiple shadows from it to utilize copies of the aircraft carrier as her own weapons.

Bringing ten shadow ships, combined into an unwieldly bird-like formation, to School District 15, Mut Thebes made extensive use of the ships as well as their onboard arsenal and technologies during her battle with Kamijou Touma (supported by Aradia) after hitting Anna with the Shrink Drink rained from its cannons, but the ships were brought down by Aradia lowering the ship's anchors irregularly, using their formation and their own weight against them.

Trivia

 * As with previous designations for Academy City's technology and weaponry, the Hs in HsB-AD-CVA01 stands for Hard Science. The HsB designation has previously been used to refer to bombers (Hard Science Bombers). However, given that the Fugaku is a seaborne aircraft cruiser rather than an airborne bomber, the B might be a (retired in real ) for . Similarly, in terms of, AD is a designation for  and CVA is a retired designation for an attack.
 *  was the code for a proposed United Kingdom aircraft carrier, intended to be the first of a class meant to replace the Royal Navy's existing carriers (most designed pre/mid-WW2), designed but cancelled during the 1960s.
 * Aside from an for, Fugaku is also the name of a  and  during World War II.
