The 2nd and 3rd Imperial Fleets have been successfully recomposed of 70,000 Eclipse SSDs; bolstered by 10,000 Executor SSDs and 20,000 Imperial Star Destroyers. Construction of the 4th Imperial Fleet is underway. The new fleet will feature advanced energy shielding, and will consist of 40,000 Eclipse SSDs, 60,000 Executor SSDs, and 135,000 Imperial Star Destroyers; along with a new flagship SSD that is based on the Eclipse model, but is 45,000m long as opposed to the original 35,000m. The new model will be built around a 2nd Galaxy Gun, and has been dubbed the first Dreadnaught class SSD. Mass production will be nearly impossible; though Dreadnaught class SSDs are being built for the 2nd and 3rd Imperial Fleets to act as flagships. Plans for the Grand Imperial Fleet are underway, but production will not commence until the completion of the 4th Imperial Fleet.
