Mobile Fortress "Great Wall"

What some would call an "outdated amalgam of weapons," Vastime calls "one of the strongest land-based weapons." This is the result of a plan by the now-defunct Bernard & Felix Foundation, originally conceived during World War Three. The initial plan for it was to be a moving command post across the wastelands that were starting to cover earth. It would be limited in where it could go due to no ship being able to carry it. Even the Suez Canal is somewhat difficult for it to cross. Surprisingly, not much has changed about the the massive walking fortress since then. It was abandoned half-finished in a facility in central Africa, and its completion was only recent finalized by Vastime. They recognized its might and purpose.

Great Wall is massive. There is no understating that. It is approximately 600 meters tall. For comparison, the entire height of the Empire State Building is around 440 meters. The truly immense part of Great Wall is its deckspan. Great Wall, from deck tip to deck tip, is approximately 2,400 meters wide—around a mile and a half. Its weight is... honestly irrelevant. The fortress is made of multiple layers of concrete and reinforced steel. It weighs in the millions of tons, probably around 3-4 million. It is a miracle of modern science and engineering it can hold itself up, let alone move.

Great Wall is split into three distinct sections—the core, the decks, and the legs. The core of Great Wall is a small city in and of itself. As it effectively does the work of two aircraft carriers along with being a forward operating base, it has the capability to hold up to 3,600 personnel. However, its usual complement is somewhere around 2,100. Most of these are support officers for the fortress itself. The core houses all internal computer systems, the reactor, Combat Information Center, storage (except for aircraft), and residential areas.

The CIC takes up the entirety of the "top" of Great Wall and is also known as "the castle." It has two bridges (of the traditional maritime sense), one forward and one aft. The forward is considered the main bridge, while both take orders from a fortified room between them. This room is the actual CIC and is nicknamed "the throne room." The main part of the castle is not the CIC, but Great Wall's main weapons. Two large three-gun turrets sit on either side of the CIC. These guns are described more below. Beneath the CIC is the large server bank and officer's quarters. General quarters are mid-level, with storage being near the bottom of the fortress.

The reactor is split between four smaller nuclear reactors. These are standard issue for most large weapons during WWIII, so they are a little out of date. However, they were in good condition so there was no need to replace them. They exist midway through Great Wall, right above the legs. They are designed in such a way that Great Wall can operate normally with one reactor down, can still operate in a combat situation with two down, and can still retreat or allow for evacuation with three down. There are numerous emergency electrical storage rooms whose purpose is to allow for doors to operate during emergency conditions.

Great Wall also serves as a land-based aircraft carrier. It has six large decks, each one capable of fitting onto a modern supercarrier. These decks are what truly give Great Wall its impressive size. The six decks are stacked on top of one another and can rotate out 45 degrees from the core. This means it can "spread them out" if needs to use all six. Each deck has three catapults. One is for STOL (short take-off and landing) craft and the other two are for normal carrier-based craft. These operate just like a normal carrier's catapults.

Each deck is rather thick near where it connects to Great Wall's core. This allows for a hangar to be present within each deck, each one capable of holding 10 carrier-based aircraft and 6 helicopters. These hangars do not have their own large ordnance storage. To load a craft for combat, the ordnance is brought from the core's storage via a system of elevators. More craft are capable of being stored on-deck, but this is usually not the case as the movements and high winds have caused aircraft to be flung from the deck before.

The decks are not just for aircraft however. This is where the secondary armament of Great Wall is. The lowest decks has its heaviest armament besides the main guns. Four large 460mm recoilless cannons are mounted in two pairs along the sides of a pillbox-like turret. This hearkens to the design of old anti-air guns, as these are meant to pound fortifications and armor like the AA guns did to aircraft. These canons are comparable to a battleship's main guns from World War Two. Smaller, 380mm guns are done in a similar turret configuration on the other four decks.

There is also a large complement of missile pods on each deck. The top and bottom decks have 4 of these pods, while the middle decks only have 3 due to their shorter length. These missile pods are designed to fire the Type-1 All Direction Multi-Purpose Missile (ADMM), codenamed "Yellowjacket II." These missiles are not particularly powerful on their own. Their warheads are comparable to the AIM-9 Sidewinder. What truly makes the Type-1 special is that it has the same type of small rockets within it that most cruise missiles have. This means it can be launched vertically and it quickly change to a horizontal course. The pods on Great Wall are deadlier because of the sheer amount of Type-1s they fire. Each pod is divided into a section. Each section has 25 tubes for Type-1s. Each pod has 7 sections—totaling 175 missiles per pod. A full barrage would have 4,900 missiles flying out of Great Wall at once.

Great Wall is propelled by 6 massive "legs." These legs incredible in their own right. They are broken into 2 types of legs—propulsion and stabilization. The four propulsion legs are at the sides of Great Wall, extending at a 45-degree angle from the main body. These are given an additional range of motion, as they can move side-to-side. Despite the massive size, Great Wall has a decent speed. This is only because of how much ground the legs cover when they walk. Great Wall can move at about 5 miles per hour.

As mentioned above, the main armament of Great Wall is not its massive missile payload nor its large under-deck cannons. No, the large turrets on its core are. These things are known as "Meter Cannons," as their bore is 1 meter. This is a 3.2-foot-wide rifled hole from which a a shell just as wide is fired. They are based on the design of the Schwerer Gustav's cannon from World War Two. They are meant to shell a fortress and destroy it within a few days. The massive cannons are not railguns nor energy, so they do have a limited range—of about 60 miles.

Now, by now someone is wondering "if this thing so damn big and powerful, how the hell do we beat it?" It's simple. A single person probably can't. You'd have a hard time punching through the armor, but it can be done. The easiest way, however, is to destroy the large, external weapons. The one thing the fortress does have an issue with is fire control. If enough weapons are destroyed, it has the possibility of igniting fuel lines or ammunition storage.
