Jupiter-class supercarrier

The Jupiter-class supercarrier is a class of carriers of the Terran Navy. They are the largest ships in service in any military navy. The class has a planned total of 7 ships, with four having already been completed. It is also one of the most advanced ships types in galaxy, being equipped with the strongest shields of any ship.
The ships of the Jupiter-class serve as mobile operating bases in the case of extended wars away from Federal territory. Jupiters are capable of transporting thousands of strike crafts by themselves. The ships themselves, whilst proportionally more lightly armed than a cruiser or a destroyer, they still carry a large amount of firepower, most of which is concentrated in their 38 DHPA Turrets. They however mostly rely on their strike craft carrying capabilities for battles, and generally see little direct action remaining behind the bulk of the fleet as a command center. Supercarriers have room for a large number of officials, and are in theory capable of being the center of Terran Government if Earth and the other core worlds were to be jeopardized. 
The class is named after the planet Jupiter in the Solar system. There are currently four completed Jupiters:
* FNS JSC-1 Milky Way, of the First Armada
* FNS JSC-2 Andromeda, of the Second Armada
* FNS JSC-3 Alcyoneus, of the Fifth Armada
* FNS JSC-4 Eye of Sauron, of the Sixth Armada
Three more are planned, two of which are currently being constructed:
* FNS JSC-5 Messier, planned for the Third Armada
* FNS JSC-6 Cygnus, planned for the Fourth Armada
* FNS JSC-7 Maffei, planned for the Thirteenth Armada
Supercarriers are the largest ships to ever be built for military purposes, and are also the heaviest ships by hull mass ever created. They are also renowned for their extremely powerful shields, which are over three times as powerful as Saturn-class shields which are the second most powerful.
