Description

Landing Castle are massive Martian space carriers. There are 37 Landing Castles, each one commanded by and named after the 37 Orbital Knights
Landing Castles are roughly 2 km in length. Each Landing Castle are their own distinct military force.

Landing Castles are designed to be dropped from orbit onto the surface of a planet. They were most likely originally intended to be used to construct colonies on Mars or other planets.

While in orbit, its four "flower arms" are closed and rotate clockwise around a central section to keep its axis stable using the gyroscopic effect. The rotation being stopped is part of the preparations for descent to the target location on the ground below.

In order to withstand the tremendous heat and impact of dropping down with several times the speed of sound, its outer side has heavy armor which doubles as protection against any attacks from the ground during descent.

The sharp tip on the lower side stabs into the ground and the kinetic energy of the castle drives it far enough into the ground to stabilize the structure. A useful side effect is the enormous shock-wave which obliterates anything and anyone in the near vicinity of the landing zone. Before the war, this was most likely used to make the ground around the landing castle easier to build on, but during Operation Earthfall it became a convenient means to clear the landing area of any hostiles. The Aldnoah Technology on board most likely prevents the crew from getting flattened by the enormous G-forces upon impact.

While approaching the landing zone, its four "flower arms" begin opening and once the landing is complete, the landing castle stands there with all four arms wide open, although some decoration details vary from castle to castle.

Once landed, the castle serves as a base of operations and is not meant for direct combat. For defense it relies on the Martian Kataphrakts of the Orbital Knights.

As they are colonization vehicles, they severely lack internal security, making them very vulnerable to enemies who managed to get inside.

Landing castles are also capable of leaving Earth's atmosphere under their own power and returning to space if the situation demands.
