Normal travel speed of starships is counted in parsecs/day and typically is 1-2/day, with most of the imperial fleet moving at 2 pc/day. Most new imperial warships are 3 pc/day and some special ships reach 4.5 pc/day.

Most normal starhips are TL 10, The newest imperial warships and noble ships are TL 11. Many older ships are still in use with some TL9 designs still in use in millions.

Traditional Starship design is a tube with multiple decks allowing actions in the thrust even if the gravitic compensators fail and allow operations at higher accelerations than grav compensators can compensate for. (Always in TL 9 designs as they do not have grav compensators unless retrofitted, The norm in TL 10 as early grav compensators were fairly unreliable and low compensation, still common at TL 11 due to both tradition and possible combat damage in military ships at TL 11, very uncommon in civilian ships at tl 11)

“New style” layout consists of a main deck and other decks rotated 90 degrees from the direction of thrust usually having a main corridor along the length of the ship. (The normal layout in most TL 11 civilian ships and in smaller TL 11 military ships like scouts)

• Scouts are normally less than 30 meters long, weight about 300 tons and have a crew of 4 to 8. They are used for scouting,survey and general utility use. The empire operates millions of these. Many of the newer ones have cloaking devices making detecting them very hard.
• Corvettes are not used by the empire, but some local defense forces use these 1000 ton/50 meter long ships.
• Frigates are the normal light warship. They are less than 70 meters long and weight about 3000 tons. They are big enough to carry reasonable armament and several squads of troops, allowing operation alone if need be.
• Light cruisers are built on hulls under 100 meters and weighting 10 000 tons. They are operated by most armed forces, but the empire is not building any more of them as the increased capability of the new frigates combined with the smaller operating crew and other requirements have made this class obsolete.
• Heavy cruisers are the main warship. Built in 150 meter long 30 000 ton hulls, these war machines are bristling with armament. They form the main combat force of the imperial fleets.
• Battleships are a new development, These huge ships are almost 500 meters long and built on a million ton hulls. They are meant to give a core of heavy firepower to the most important fleets. However their survivability in combat is not yet proven and each is a huge investment. This, combined with their inability to use the gates due to the weight has caused a lot of skepticism.

These are the main ships of the space forces, they fight and scout both in the imperial fleets and other services.

These ships transport troops across interstellar distances.

Carriers are mainly used to carry fighters over interstellar distances.

Fighters provide for a force that is spread out and thus hard to take out and provides some combat presence in many places. Only in right circumstances can they take on heavy forces, but the fighters can help bring down the screens of enemy ships of the line making them vulnerable to friendly ships fire.

Forts provide immobile protection for major planets and space stations.

Monitors provide mobile defense for major systems.

Drop ships are used to get troops down in opposed landings.

Utility shuttle are for all types of transport missions in imperial service.

Assault cutters are for transporting troops to boarding actions.

Assault shuttles are ships that combine the roles of utility shuttles and assault cutters and can usually also be used as drop ships.

The fleets need a lot of supplies delivered. These armed ships can transport such without additional escorts.

These ships transport the mail for everyone in the empire.
