GS-PSS125 Astronomer-class

The GS-PSS125 Astronomer-class is an advanced mobile gear carrier battleship which acts as a mobile fortress and base for the Gundam Gear units. It is featured in Mobile Gear Gundam Blues.

Technology & Combat Characteristics
The GS-PSS125 Astronomer battleship was developed as a moving base for the Gundam Gears to be refueled and resupplied, and act as highly fortified transportation for the units. Using beyond state-of-the-art technology in its base, the Astronomer-class was designed with the intent to create an unsinkable monster of a ship.

The Astronomer boasts a complete arsenal at its disposal, with a pair of rotating Pulse-based Mega Particle Cannons, ten Beam Turrets mounted on the sides, eight 60mm Gatling Guns on its top surface, and several hidden Missile Condenser launchers. Hidden in the front nose of the ship is a powerful frontal weapon of mass destruction, known as the Beam Breaker, which launches rapid energy particles across a radius as big as the Astronomer itself and at a range of 50 kilometers. The ship can also stretch a thin electromagnetic barrier across its surface to act as a shield against most attacks while still being able to fire most of its weapons.

The ship is made out of several hundred micro-layers of self-cooling titanium alloy, which is able to withstand most kinds of damage done to it with little more than a scratch and a dent. These armor plates are then placed under a complex electrical system for the ship's Electromagnetic Barrier to operate properly. The surface of Titanium is painted black in order to give the ship some form of camouflage whilst it is traveling. Some components are also made of a Tungsten composite, mostly with parts dealing in the ship's internal mechanisms.

The Astronomer is the first ship to be equipped with a portable FTL Linear System, called the Shipbound Linear System (or shortened to SLS), allowing it to move nearly instantaneously from one location to another across a vast distance by essentially firing itself across the distance with a localized wormhole. The SLS unit gives the ship the ability to go wherever it wants without needing to use an FTL Hopper gate.

The sides of the Astronomer come with a pair of Mobile Gear catapults, meant to launch gears and other equipment out into battle. However, instead of a momentum-based catapult, the Astronomer uses magnetic plates and electric plates to fire the gears at blinding speeds into combat. These Railgun Catapult Units fire objects at a speed of approximately Mach 24 (18,414.5 miles per hour), technically classifying them as a weapon in their own right as whatever they fire can and will piercing straight through anything in their path. If the ship has seen extensive service, mobile gear shrapnel or broken off pieces of the ship's armor can be fired from the Railgun Catapult as a projectile weapon.

A limited series of 254 Astronomers were constructed and distributed in order to operate across the entirety of the Orbital Boundaries. These are usually crewed with 128 GUNSYS personnel, which include the captain, bridge crew, engineering staff, teams of mechanics, medical staff, CIC crew, and the Mobile Gear pilots.
