Builder: A mysterious instrument handed down in this world, the construction, operation, and operating principle are completely unknown, and it can build (summon) the unscientific existence of the "ship girl" ship-making machine: The Federation has spent a lot of time and money to invest in the "copycat" product made by relying on the style of the builder, and it can make an ordinary ship-equipped with a greatly reduced power, which was originally intended to be abandoned, but after the launch of the "Construct Warrior Queen" program, it became one of the core instruments

Nuclear weapons: one of the terminal scientific and technological products developed by the federal side (please refer to Baidu Encyclopedia for specific principles)...... It is worth mentioning that nuclear radiation is also very harmful to the ship's mother and the construction of the battle queen

Ship Niang: 1. From the development of sails to steam power, and then to the present fuel consumption, along with the strengthening of power, the increasing resource consumption has also become a huge burden

2. Synonymous with giant ship cannons, unscientific armor defense and cannonball attacks have made these girls who dance with steel and blue waves become well-deserved queens of war

3. The types are roughly destroyers, light cruisers, heavy cruisers, battleships, battle cruisers, light aircraft carriers, regular aircraft carriers

4. The existence of exclusive ship equipment allows them to maintain a certain combat ability on land, but it will be greatly weakened with the increase of distance from the main body, and the attack range of the ship equipment is also limited by unknown factors

Construct the Warrior Queen: The whole body equipment is modified from the combination of ship outfit or mass-produced ship outfit, which can be called a "super soldier" to a certain extent, but because only women can be equipped and used, it is called a constructing Warrior Queen, and the current technological stage is roughly divided into "Divine Queen", "Warrior Queen" and "Steel Dancing Queen"

Shen Ji: The number is scarce, the whole body is equipped with a composite structure transformed from the ship's equipment, the specialty is that it can carry out all-round amphibious operations on land, sea and air, and is limited to the energy combat module, with strong high combat capabilities and excellent detection and action, and the active range is the entire northern continent and the war sea area against deep-sea habitat ships

The only drawback is that it cannot be equipped with a powerful enough weapon of mass destruction, so the threat to large targets is limited

War Queen: There are a large number of them, and the equipment is a normal structure transformed from a mass-produced ship, which can be used for amphibious operations on land and sea, and the Federation is active in the coastal areas of the northern continent as the backbone of the replacement ship mother against the deep-sea habitat ship

Because of the problem of the construction volume, there is no way to carry a large amount of energy, and it is impossible to carry out long-term high-intensity combat Steel Dance: there are many of them, and the equipment is transformed from the ordinary construction of mass-produced ships, and the ability to play on the sea surface is far less than that on land for some technical reasons, so most of them are active in the internal areas of the continent and exist as a replacement for traditional tanks and soldiers.

Because it could not pose a threat to deep-sea perching ships in the sea, the Federation did not invest in large-scale development

God's Scepter (Space-based Kinetic Energy Weapon System): One of the terminal technology products developed by the deep-sea side, consisting of two satellite platforms located in low orbit, one is responsible for communication and locking targets, and the other is equipped with a large number of metal long rod-shaped kinetic energy "cannonballs" called "God's Staff". The missile body is mainly composed of five parts: kinetic warhead, propulsion system, guidance system, thermal control system and communication system. The warhead is mainly cast from high-density metals such as tungsten, titanium or uranium, and has a slightly pointed front, which can reduce air resistance and reduce kinetic energy loss when reaching the ground. The "Scepter of God" usually strikes a target in the form of a vertical attack, just like a meteorite hitting the earth, so it gains a huge amount of kinetic energy, and the destructive power generated when it hits the ground is also quite large, its power is equivalent to a small nuclear bomb, and can easily penetrate the inside of the target hundreds of meters underground, and this alone can eclipsate any ground-penetrating bomb.

At present, it is mainly used to destroy the town guard house on the mainland defense line at a fixed point, and to a large extent, the decline of the battle mode between the town guard house and the ship mother is caused by it.

Deep-sea Celestial Habitat: 1. Diametrically opposed to the traditional deep-sea habitat ship, a huge fortress suspended in the sky, the farthest horizontal attack distance can even reach more than 80,000m
