Space Battleship Yamato (First refit form)
Earth’s most extraordinary ship, re-equipped with a Wave-Motion Gun
After returning from Iscandar, BBY-01 Yamato, the first ship of the Yamato class, was temporarily laid to rest in the undersea dock as a memorial ship. However, she returned to the battle line in response to the Earth Federation Government’s “Wave-Motion Gun Fleet” concept. At that time, Yamato underwent a renovation and was reborn in its “first refit form.”
The first refit was carried out on the occasion of the Yamato redevelopment plan. Many changes were made, including the restoration of its Wave-Motion Gun. The main changes included the shape of the bow fairing, the bulbous bow, and the torpedo tubes. The volume near the bulbous bow and torpedo tubes was increased, and the lower part of the hull was expanded in cross-sectional view. The main propulsion nozzle was enlarged, and the main gun turrets were enlarged in accordance with an increase in their armored plating.
The height was changed for some of the turrets, the triple high-angle guns on both sides of the second secondary turret were removed, and eight twin high-angle guns were added. A fourth bridge was newly built behind the base of the second secondary turret. More onboard factory facilities were added, and there was an increase in spare materials due to a drastic reduction in the number of crew compartments.
This series of modifications improved Yamato‘s weaknesses from the time of her maiden voyage. Yamato was launched by her former crew after receiving a message from Telezart, departing from Earth as if in mutiny.
Armor/Bulkheads
The basic structure of a “ship” inherited by Yamato
Even though Yamato is a space battleship, it is still a “ship,” and its basic structure is similar to that of a seagoing ship in many respects. Specifically, there is a keel that runs through the bottom of the ship from front to back. The frame extends from the keel like ribs, and bulkheads divide the interior of the ship into compartments.
The armor covering the ship’s hull seems to be an “old” technology, reminiscent of large combat ships up to around World War II. However, even though the ship is equipped with a Wave Barrier, the armor is an important defense mechanism for space battleships, which can be attacked from all directions, and also contributes to improving the strength of the ship.
Yamato (and other space ships) has the basic structure of an old ship due to the need to withstand hull movements such as pitching a rolling. Bulkheads are used to support each compartment of the ship, making them airtight and watertight. This leads to the merit of facilitating damage control.
There is no submersion in space, but if the ship is damaged to the extent that its armor is penetrated, the bulkheads help to minimize air outflow and incidental damage. It goes without saying that air leakage and collateral damage must be minimized. Since it is also expected to operate above and below water, bulkheads that form airtight and watertight compartments are indispensable.
Yamato under renovation
The structure of Yamato, especially the position of the frame, can be easily seen in the figure of Yamato during refit work. During the refit, most of the armor was removed to expose the frame. (Because the width of the frame exposed during the renovation is relatively wide, there is also the possibility of bulkheads being installed every few frames.) The volume of the lower hull was increased in the refit, but this is believed to be due to reinforcement of the armor. It is unknown how much change was made to the frame.
Captain’s quarters / Wave-Motion Gun rangefinder / radar
Captain’s quarters and observation equipment located at the apex of the bridge structure
At the top of Yamato‘s bridge structure is the captain’s quarters, a private room reserved for the captain. Between the captain’s quarters and the first bridge are the Wave-Motion Gun rangefinder and the Type 99 dimensional radio detector. The basic layout was not changed during the first refit. The Wave-Motion Gun range finder and the Type 99 dimensional radio detector were moved slightly upward. The arm supporting them has also been slightly increased in thickness.
Various modifications were made to Yamato in the first refit plan. However, parts that were judged not to need repair were left untouched. It is well known that even materials from the “Izumo Plan” were left on board. The captain’s quarters is considered to be one such area. Even the interior furnishings have not changed since the time of the first captain, Juzo Okita.
Functional changes of the Wave-Motion Gun rangefinder and dimensional radio detector, which are located below and on either side the captain’s quarters, is unknown. However, the dimensional radio detector was temporarily removed during the refit, so it may have been replaced with a newer model or improved. The wave defense relay behind the captain’s quarters also remains unchanged, since it is a necessary piece of equipment, though an improved version may have been installed.
Mounting position and reinforcement
In the first refit, improvements were also made to the anti-aircraft pulse laser guns. The triple anti-aircraft pulse laser guns on both sides of the second sub turret were removed, and eight double-barreled high-angle guns were added. Similar or newer anti-aircraft defense weapons were also installed on newer ships such as the Andromeda class.
The effectiveness of these weapons was highly evaluated. In the case of Yamato, though, the number of such weapons is much greater than on its successors. This is due to the fact that Yamato was designed to operate as a single ship, and it was further augmented by its Final Battle Specifications.
Bow
The bow area was also modified in the Yamato refit project. The bulbous bow and the volume around the torpedo tubes were increased. The torpedo tubes were renumbered, with the port torpedo tubes numbered 1, 3, and 5 from the bottom. (The starboard torpedo tubes are numbered 6, 4, and 2 from the bottom).
Attitude control nozzles
In contrast to the stabilizer wings that can be considered an attitude control system for atmospheric use only, the attitude control nozzles are effective both inside and outside an atmosphere. It is a group of thrusters used for maneuvering, mainly during combat. They are mounted on the bow, stern, and the ends of the hull, as well as on the bottom of the ship. The nozzle shown in the lower image is a small model and plays an auxiliary role to a larger model called a “thruster” for combat use, or for attitude control during non-combat.
Bow torpedo launcher
Yamato‘s largest solid ammunition weapon
Yamato is equipped with six torpedo tubes on her bow, just as she was before the refit. (The same six torpedo tubes are mounted on both sides of the stern.) The type of mounting is similar to that of torpedo tubes on submarines, with three in each section. Although named torpedoes, they are a type of general-purpose missile/rocket that can be used not only underwater but also in atmosphere and space.
Yamato is equipped with four types of missiles, the bow (and stern) torpedoes being the largest. Its destructive power was capable of sinking even Garmillas’ Kelkapia-class fast cruisers in mid-air with a single blow. It is also one of the weapons capable of attacking dead ahead, often used to eliminate enemy ships directly in front of Yamato.
the Wave-Motion Gun and the first and second main turrets can also directly attack in the frontal direction, but the Wave-Motion Gun can only be used in limited situations, and the main turret is difficult to angle down to due to its mounting position. This clearly differentiates them from the bow torpedo, which can attack directly in front.
Its performance was fully demonstrated in the Gatlantis campaign when it was used effectively on planets Stravase and Telezart.
Torpedo
Torpedoes fired from the bow and stern torpedo tubes are 8 meters long and 65 cm in diameter. The rotor blades, which contribute to directional control and attitude stability, are engaged with grooves on the inside of the launch tubes. Before launch, only a portion of the rotor blades is exposed. After launch, they are fully deployed.
Related Equipment
The torpedo-related components at the bow are the torpedo tubes and the torpedo loading bay. The bow torpedo hangar is arranged in a connected configuration, but the torpedo facilities on each side are independent. The figure is from 2199, but the basic design has not changed after the refit.
Torpedo tubes
(port and starboard sides)
Multiple guided missile launchers protect
the port and starboard sides of the ship
Yamato‘s artillery weapons consist of the Wave-Motion Gun with ultimate destructive power, directional energy weapons such as main and secondary shock cannon turrets, anti-aircraft pulse laser guns, and guided munitions. The torpedoes or missiles, which are guided, are positioned to cover Yamato‘s top, bottom, front, back, left, and right sides. A total of 16 torpedo tubes are mounted on port and starboard.
The broadside torpedo tubes differ from the bow and stern torpedo tubes in that the former uses short torpedoes, while the latter uses conventional torpedoes capable of long-range stealth dives. In terms of firepower and range, the bow and stern versions are superior, making them more aggressive weapons. In contrast, the side torpedo has a shorter range, but the ship is equipped with eight tubes on each side, so they have superior rapid-firing capability. This indicates that the side torpedo tube is a defensive weapon. In actual warfare, they are used to intercept enemy missiles and to attack at relatively close range.
The term “torpedo” is only figurative. It is similar to a multi-purpose missile that can be used both in space and in an atmosphere.
Broadside Tubes and Torpedoes
The short torpedo launchers on the sides were chosen due to the physical limitations of Yamato‘s width, which is much smaller than its overall length. The width of the ship does not allow space for large torpedo tubes on the sides. (Torpedo tubes on the bow and stern are mounted parallel to the hull, so this problem does not exist.) As a result, a short torpedo tube with a smaller launch length was adopted. Taking advantage of the ship’s long length, an 8-tube array was adopted in which the launch tubes were arranged side by side.
Ship-bottom missile
The bottom of Yamato is equipped with multiple missile launchers
The bottom of the ship is equipped with a VLS (Vertical Launching System) missile launcher, also known simply as the missile launcher tube (bottom). When first commissioned in 2199, the ship was equipped with eight missile launchers, but the number was increased to ten in the first refit. However, due to the nature of the VLS, the launchers must be fully retracted into the hull. It is not possible to distinguish the additions from the outside. (Only eight missile hatch units can be identified, and it is thought that they were added forward or aft of the hatch units.)
Eight missile launchers behind the bridge structure defend and attack directly above the ship, whereas the bottom missile launchers are underneath as their name implies. Although the two weapons are opposite in terms of their assigned compartments, their roles are basically the same. This can be understood from the fact that they fire the same model of missiles and short torpedoes.
The bottom missile launcher, however, can be used for ballistic attacks during “submarine maneuvers” in which the top and bottom of the ship are inverted underwater. It also has advantages such as high rapid-firing capability.
Bottom missile launcher
Yamato‘s hull is covered with strong armor, but this armor also makes it difficult to mount defensive weapons. The bottom missile launcher was adopted to solve this problem. The VLS system minimizes openings in the armor and enables attacks in the downward direction. In addition, each missile launcher is a revolver type (consisting of 6-12 launchers), which allows for intermittent attacks and equipment selection.
Yamato‘s “missile”
Except for the eight-barrel missile launcher (also called the “smokestack”), Yamato‘s missile launchers and torpedo tubes are housed within the hull. This is a trend among space ships regardless of their power, and Yamato (first refit form) has a particularly large number of them. Specifically, six missiles are mounted on the bow, six on the stern, 16 on the port and starboard sides, and 10 on the bottom. The hull alone is heavily armed with 38 units. Yamato‘s high survivability was due in large part to these missiles.
Rocket Anchor
An “anchor” with rocket ejection system for space operations
Since its commissioning in 2199, Yamato was equipped with rocket anchors on both sides of the bow to secure the ship. Unlike gravity anchors, which prevent the ship from falling back when firing the Wave-Motion Gun, the rocket anchors are physical anchors.
The difference between a rocket anchor and a seagoing anchor is its ability to operate in space. Unlike conventional anchors, which are sunk to the seabed to secure the hull, rocket anchors can be used to target asteroids and other bodies to prevent the ship from drifting in space. Like conventional anchors, rocket anchors are equipped with an anchor arm, so they can also be used to secure the ship in water. It can also be used to stabilize a ship’s attitude in the air by launching it into a surface while in flight.
It is characterized by a rocket launch mechanism. In space, where anchoring by gravity is difficult, it is a necessary component for anchoring the ship at an arbitrary opportunity. The rocket anchor itself is not unique to Yamato, but was adopted before that, and its importance is widely recognized.
Anchor Structure
The shape and features of Yamato‘s rocket anchor have not changed after the refit. The size is the same: 9m high, 6.5m wide (12.3m when the arm is deployed), and 1.7m thick. However, Yamato‘s displacement capacity increased as a result of the first refit, so the base, arms, and anchor chains, which are subject to load, have been strengthened accordingly.
Rocket Anchor
Ingenuity of the rocket anchor seen on Yamato
Yamato‘s rocket anchor (Type 97 jet-propelled space anchor) was adopted in 2199, and inherited with almost no changes during the first refit. The rocket anchor itself had been installed on space ships for a relatively long time, and was also used on the Kongo-class space battleships and the Isokaze-class assault space destroyers.
Rocket anchors were retractable on older spacecraft, but Yamato‘s rocket anchors are exposed like those of a surface ship. This was for the purpose of installing the Wave-Motion Gun, which occupies a large amount of space. The technical and structural problem of not having enough storage space in the bow of the ship was one of the reasons the exposed type was chosen. Other than that, since Yamato was the first Earth ship to navigate in deep space, the rocket anchor was required to be multifunctional to cope with unexpected situations. One example is that it serves as a rudder for elevating and lowering the ship during submarine operations in which the ship is inverted.
An anchor mounted on both sides of the bow, like a surface ship, is thought to be designed for anchoring in water, which is negligible in a normal spacecraft, but is considered suitable for operation on celestial bodies with hydrospheres.
Control mechanism
Unlike the anchors of surface vessels that are lowered to the bottom of a sea or river, rocket anchors have a degree of freedom in the direction of projection, since the potential position of the anchor’s target is not fixed. In Yamato‘s case, the rocket anchor launcher has a variable range from directly lateral to almost directly below the ship. On the 11th Planet, for example, the rocket anchors were driven laterally into the cliffs on either side of the ship. The anchor launching operation is performed in the rocket anchor control room adjacent to the rocket anchor launcher on the bow, but it can also be operated from the first bridge.
Wave Barrier
Wave Barriers that play a part in Yamato‘s defense
The equipment and facilities that play a role in Yamato‘s defense can be broadly classified into three types: the physical armor covering the hull, the interceptor weapons (represented by the anti-aircraft pulse laser guns), and the Wave-Motion Barrier.
The Wave Barrier is a non-physical armored energy system based on the same Dimensional Wave Theory as the Wave Engine. It is deployed as needed, since it cannot provide constant protection like physical armor. It is difficult to deploy for a long period of time, and if it is continuously exposed to impacts, it will be disabled. The main limitation is the time constraint, but it was widely used in combat because of its extremely high defensive capability against both energy weapons and solid munitions.
The first refit type, which entered service in 2202, inherited and reinforced the Wave-Motion barrier. Although it was not ready for deployment at the time of its launch, it was activated during the battle against Andromeda in the asteroid belt, protecting Yamato from Andromeda‘s shock cannon and ship-to-ship collision. In subsequent battles, it protected Yamato many times.
After that, the Final Battle Specification upgrade was considered to be deployable immediately after a warp. A tactic using this function was adopted in the battle against Neu Deusula.
Wave coil installation location
An important device in the operation of the Wave Barrier is the wave coil stored on the ship’s sides. In 2199, Nambu Heavy Industries’ Type 99 wave coil was used. Yamato was equipped with the same standard or an improved type in both the first refit form and Final Battle Specs. The deployment site of the Wave Barrier differs depending on the position of the coil. In 2199, the starboard unit deployed above the waterline, and the port unit deployed below. (This is not necessarily true for the first refit type, since the waterline was changed.)
Stabilizer wings
Yamato‘s stabilizing wings are more than just “wings”
Yamato has built-in stabilizing wings called “main wings” on both port and starboard sides. Normally, they are stowed and deployed as needed. Specifically, they are stowed in space and deployed in atmosphere where aerodynamic control is effective. (They do not deploy underwater, perhaps because of the increased drag.)
Yamato is a space ship capable of flying at zero speed, or what is called a midair stop, and has a high attitude control capability in atmosphere. It can also fly in atmosphere using only the thrust from its Wave Engine and auxiliary engine. Even so, the wings are deployed during atmospheric flight because they provide lift and aerodynamic attitude control, which improves stability regardless of speed, and because they do not require the use of Wave Energy.
A stabilizer wing also has aspects other than being an aerodynamic device. It functions as a composite heat dissipation device, which can be used for air cooling in atmosphere and for radiation (heat dissipation in the form of infrared rays) both in and out of atmosphere. Therefore, it is thought that the stabilizer wings may be deployed in space under certain circumstances. Stabilizer wings with these characteristics were used extensively during the Battle of Gatlantis.
Stabilizer Wings
Stabilizer wings are combined aerodynamic and heat dissipation devices mounted on both port and starboard sides. They were previously positioned above the waterline, but after the first refit, they are lower due to the rise in the waterline (though the position of the stabilizing wing has not changed). The stabilizing wing itself consists of multiple panels, and the wingtips and trailing edge flaps are movable. The cross-sectional area of the wing is asymmetrical, as is the case with ordinary wings. When deployed, the wing is extended horizontally relative to the hull, then the leading edge is lowered by approximately 2 degrees.
Aft ramp loading/unloading port
The aft ramp is used for loading and unloading personnel and cargo under gravity, though this is often done via the hatch at the rear of the third bridge. (Transport by shipboard aircraft is also possible.) However, due to the limited capacity of the core elevator leading from the third bridge into the hull, it goes without saying that other entrances and exits are necessary. One such entrance is the aft ramp loading/unloading entrance on the port side of the ship. A ramp is attached (stairs for embarkation and disembarkation), allowing large numbers of people to embark and disembark at the same time.
Asteroid Ship
The asteroid defense system, a legacy of the “Izumo Plan”
Yamato was completed as a super dreadnought space battleship equipped with a Wave-Motion Engine, thanks to technology provided by Iscandar. It was originally built as an escape/emigration ship in accordance with the “Izumo Plan.” One component of that plan was a flight configuration in which the ship’s hull was covered with a mass of rock, transforming it into a so-called “Asteroid Ship.” (Additional crew compartments outside the ship would also be covered by a rock mass.) In order to control and guide masses of rock to the hull, a large number of magnetron probes would be used.
The basic policy of the “Izumo Plan” was to use the controlled rock masses as camouflage and auxiliary armor. However, with the decision to go to Iscandar, and the practical application of the Wave Barrier (which offered a higher level of defense), the “Izumo Plan” was abandoned.
However, even after the Yamato Plan was launched, improvements were made at the suggestion of Shiro Sanada. This was the “ARGO system,” a defense mechanism that deflects enemy artillery by rotating at high speed while deploying multiple layers of asteroid rings. This system was used for the first time during the Gatlantis battle, and was also used for operations other than defense.
Magnetron Probe
The operation of the rock mass in the ARGO (Asteroid Ring Generated Offense) system is carried out via a group of remote control devices called magnetron probes. The magnetron probes are inserted into rocks around Yamato and manipulated by magnetic force. The magnetron probe itself was onboard Yamato in 2199, but was kept in storage and not used during the voyage to Iscandar. It was used for the first time in 2202.
Operation
There are two ways in which the system can be used defensively. One is to cover the hull with a mass of rock that also serves as camouflage. The other is to rotate an asteroid ring at high speed. The former and the latter are not a binary choice; both can be used flexibly. The “O” in “ARGO system” stands for “offense.” It is said that ARGO was originally an offensive system, but it is not known what kind of attack method it was originally designed for.
Yamato landed on the planet Zemulia
In the final stage of the Battle of Jupiter, when the Earth Federation’s space fleet and the Gatlantis Empire’s main fleet clashed, Yamato returned to the solar system and planned to attack the Comet City using a Transit Wave-Motion Gun. However, after the Wave Engine was stopped due to the activation of the anti-wave lattice, Yamato disappeared into the fog of the Comet City.
Yamato was missing for a while after that, but had not been destroyed. It crash-landed on the planet Zemulia, which had been captured by the Comet Empire’s planet catcher. (When Yamato‘s wave engine stopped and the “fall” to the Comet City Empire became critical, most of the crew escaped under the direction of Captain Ryu Hijikata.)
After crash-landing on Zemulia, Yamato was damaged to a considerable extent, and the climate gave it a rusty, reddish appearance. Nevertheless, it recovered to a state where it could navigate alone by reactivating its Wave Engine. In the midst of the battle over the Comet Empire City, it rejoined the Earth Federation Forces. It then returned to the battle line with Final Battle Specifications, having been repaired and strengthened from the damage it sustained.
Burial Situation
Yamato was pulled into the Comet City Empire and crash-landed, half-submerged, on the surface of the planet Zemulia. The only part of the ship exposed on the surface was the upper deck, but there seemed to be enough space to launch aircraft from the third hangar and the ground vehicle hangar.
Although it may seem difficult to escape from a burial situation, the ship had previously escaped from a state of complete burial on the 11th planet. However, the power loss suffered during the Zemulia crash landing made this a difficult task.
Final Battle Specifications
Yamato reconstructed for the final Battle of Gatlantis
At the end of the Battle of Jupiter, Yamato was severely damaged in its crash on the planet Zemulia. Before the decisive battle against the White Comet Empire, Yamato was repaired and refurbished in the emergency dock in Mars orbit. This is Yamato/Final Battle version.
In the Final Battle Specifications, the main guns were strengthened, anti-aircraft and close defense weapons were increased and automated, the radar above the first bridge was replaced, and the Wave Barrier could be partially deployed immediately after warp.
Yamato‘s second main turret was severely damaged in the crash on the planet Zemulia, so it was replaced by Ginga‘s first main turret. All anti-aircraft and close defense weapons were also transferred from Ginga. This new system of gunnery weapons had already been proven on board Ginga. Thus, Yamato was strengthened with a focus on firepower.
With the cooperation of the Garmillas fleet, Yamato was able to enter the interior of the White Comet Empire, making a great contribution to the end of the Battle of Gatlantis. Yamato suffered unprecedented damage in the battle, and was restored to a state equivalent to the first refit type after the war. A new refit plan seems to exist, but the specific plan has not yet been announced.
Fuselage Structure (1)
The Yamato/Final Battle Spec form is a refit that focuses on heavy armament. A number of firearms, including pulse lasers, was added on the first deck. This meant making the ship top heavy (high center of gravity), which could lead to instability in the ship’s behavior. However, the first refit form, which became the base for the Final Battle Specifications, was more massive than the Yamato of 2199, and its center of gravity was shifted toward the bottom of the ship. Therefore, there seems to have been no major problem with the additions to the deck.
Fuselage Structure (2)
At the time of conversion from the first refit form to Final Battle Specifications, the radar on the first bridge changed Yamato‘s image along with the addition of firearms. The Type 99 cosmo radar was replaced with a larger high-dimensional micro-radar, giving the impression of being top-heavy. This series of modifications seems to have forced Yamato to increase its mass, but no enhancements to the Wave Engine or auxiliary engine have been confirmed.
Final Battle Specifications
Increased “defensive capability”
In response to the “Wave-Motion Gun Fleet” concept, Yamato was recommissioned and renovated into the “first refit form” under the leadership of Shiro Sanada. This Yamato reflected the lessons learned from the Garmillas War. As a part of this, “defensive capability” was expanded in a comprehensive sense.
Specific examples are an increase in armor plating on the main gun turrets, and installation of a new armor cover on the quadruple high-angle guns located below the high-angle gun fire control system. Removal of the three high-angle guns on both sides of the second secondary turret resulted in the addition of eight high-angle guns. In other words, not only were defenses strengthened, but interception capabilities were also enhanced by increasing anti-aircraft artillery.
During the final battle against the Comet City Empire in the Battle of Gatlantis, Yamato was upgraded again to “Final Battle Specifications,” which further expanded its defensive capability in a broad sense, especially its anti-aircraft artillery. About 30 anti-aircraft guns were added, which barely prevented Yamato from being destroyed in the battle to invade the Comet Empire City, permitting the ship to reach the center of the Golem.
However, this was a temporary modification, and the configuration was later returned to first refit form.
Reinforced defensive equipment
The Final Battle Specifications added the following enhanced anti-aircraft guns:
Two small anti-aircraft guns on the upper side of each main turret.
Six four-barrel anti-aircraft guns (large) in front of the first main turret.
Two quadruple anti-aircraft guns on both sides of the first secondary turret.
One triple anti-aircraft gun and a small anti-aircraft gun on each side of the base of the command tower.
One triple anti-aircraft gun (square) on both sides of the second secondary turret.
One large quadruple anti-aircraft gun and one twin anti-aircraft gun on each side of the inner fireboat hangar.
Two quadruple anti-aircraft guns (large) on the rear deck behind the third main turret.
Reinforced firepower
The main gun and guided missiles have also been strengthened, and Yamato‘s overall firepower has surpassed that of the first refit form. The shock cannons were enhanced by adding an energy condenser to the side of the main turrets (increasing them to 50cm caliber equivalent). Another example is the addition of four triple vertical missile launchers to the deck in front of the first and second main turrets. The effect of this increase in firepower is significant. In the Battle of Golem in the Comet Empire City, it destroyed a Gostok-class ship equipped with anti-matter missiles in a single blow.
Yamato class ships
Specifications of the Yamato class ships and their variations
The super dreadnought Space Battleship Yamato has multiple variants. BBY-01 Yamato is the first ship, BBY-02 Musashi is the second, BBY-03 Ginga, the third. (The existence of a fourth or later ships is unknown.) Of these, Yamato and Ginga are widely known for their activities in the Battle of Gatlantis, though the specifications of each are completely different.
Yamato was once decommissioned, but was re-commissioned in response to the Wave-Motion Gun Fleet concept. Ginga is a wave experiment ship equipped with the Cosmo Reverse System instead of a Wave-Motion Gun. In addition to this, Yamato was transformed to first refit form at the time of re-commissioning, then to Final Battle Specifications at the time of the decisive battle against the Comet Empire City.
The basic structure of each ship is the same, but the bridge structure, armament, detection system, and onboard facilities have been changed or modified from the Yamato of the Garmillas War. One common feature is the emphasis on manpower. It is not clear whether new Yamato-type ships will be built in the future, but there is no denying the possibility that it will become a vessel with a concept that separates it from labor-saving unmanned ships.
Final Battle Specifications
Yamato (first refit form) suffered major damage when it fell to the planet Zemulia, then was strengthened and modified, though the hull itself remains unchanged. The main changes were the addition and enhancement of armament, and the radar on the bridge structure was changed and enlarged, giving the ship a top-heavy image (high center of gravity).
