Part 04: Who has Dreadnoughts?
The Sathar first introduced such a craft, a robotic cruiser/carrier combination dubbed by the UPF as "the Juggernaut". If the sathar have more of these monstrosities, and in varying configurations, they stand to hold a better hand against the UPF in an invasion. Imagine a full on carrier of the same size, dropping out of the void along with a contingent of destroyers, and launching multiple squadrons of fighters to take out UPF warships while the destroyers make their way effortlessly to their targets.
It behooves the UPF to have equivilent sized carriers that can ferry variable numbers of standard, light, and heavy fighters to face such an onslaught. Hence the formation of the Operation: Dreadnought bill.
