Megalith was one of the five known superweapon created to protect Earth from the Ulysses asteroid, and the third originating from Usea, along with Stonehenge and an unnamed spaceborne laser. The construction of the facility began some time in the late 1990s, shortly after the FCU announced plans to develop a weapon to combat Ulysses.
The existence of Megalith remained unknown to the other nations of the continent. In July 3 of 1999, the day the asteroid made planetfall, the facility engaged the falling fragments of the celestial body. The laser fired from it were recorded on home video by a civilian, but the origin of the beams remained a mystery to Usea.
Continental WarEditIn the aftermath of the Ulysses event, Megalith was abandoned by Erusea, falling into disuse for several years.
Six years later, during the Usean Continental War, the Erusean military decided to use the facility against the Independent State Allied Forces after the fall of Stonehenge in April 2005. An ISAF spy plane, Leopard, obtained photographic evidence of the site, which prompted the higher echelons of the organization to bolster their war effort to defeat Erusea before its construction was completed.
A group of Erusean officers took over the complex shortly after the ISAF invasion of Farbanti in September of 2005, planning to use it against the allies as a last resort. The Allied Forces responded by launching an aerial attack dubbed "Operation Judgment Day" in September 26, involving a special forces team led by Bravo 1 and the newly formed Mobius Squadron.
The ground forces infiltrated Megalith and opened the complex's internal tunnels, allowing Mobius One to fly inside and destroy the energy generators within. After disabling them all, the Eruseans tried to fire a large intercontinental ballistic missile from the core of the facility. With the aid of the special forces soldiers inside, Mobius dove into the heart of Megalith and destroyed the missile as it took off, escaping from the silo before the core of the complex was destroyed in the ensuing explosion.
DesignEditMegalith is a massive facility designed to shoot down asteroids from orbit. The facility is armed with two laser systems, which "paint" the target asteroid(s) for the ICBMs, which are used to knock them out of orbit or break them apart into smaller fragments, which then burn up in the atmosphere. Megalith's potential as weapon can be harnessed by launching the ballistic missiles at targets anywhere within the weapon's operational range; as well, they can be used to knock asteroids close enough to Earth out of orbit, thus making them potential weapons of their own.
Several open grooves are located behind and in front of Megalith, which lead to the energy generators that power many of its systems. Deep within the facility's core is a large missile silo, which houses a "giant" ICBM. Most of Megalith's systems are operated from a sub-control room located in the 13th floor of the structure.
- Megalith's namesake comes from the word "megalith", which is a large stone used in conjunction with other large stones to build a structure or monument. Megalith's design also resembles a real megalith, with the different sections of the installations serving as megaliths.
- The design of Megalith seems to have served as a basis for the Estovakian-built Chandelier railgun system, built in the Anean Continent.
- Megalith seems to have three types of missiles. The first are small (but presumably nuclear) missiles which launch continually during the first half of the mission; these apparently are used for knocking asteroids out of orbit. After the "mission update", four larger ICBM's spawn. Unlike the smaller missiles, these can either be destroyed on the launchpad or shot out of the air by the player, netting large amount of points. These missiles probably are aimed at ISAF cities, but they likely self-destruct when Megalith is destroyed even if the player does not shoot them down before they exit the airspace (similar to V2). The third is the "Giant ICBM", the target during the second half.
- Megalith is possibly the most powerful superweapon in the series, as it is a long-range, nuclear launch facility capable of destroying cities and military bases. Many of the other superweapons in the series either are not nuclear or are only effective against air targets. Fortress Intolerance and Avalon Dam have similar capabilities, but are much smaller and contain only one missile each.
- Megalith is commonly regarded as the most iconic superweapon in Ace Combat history, not only for it's respective mission's setting, but also for it's musical pieces.
- Megalith bears an uncanny resemblance to Fortress Intolerance, the military facility faced at the end of Ace Combat 2. As well, both sites are taken out in the same way: the player character flies into the facility's core, destroys a missile as it launches and escapes before said missile explodes.
