Monitors and Forts

So one might say, if the Grand Human Union is such a peaceful, benevolent place why does the Star Legion have such devastating firepower as embodied in First, Second and Third Raters?
The answer is monitors and forts.
A monitor is a 10 to 30 million cuft warship. They are heavily armored with force fields and armed with massive energy weapons and missile launchers. Unlike battleships they typically do not embark battleriders or troops. They also typically do not have shunting capability. That means that they are limited to accessing subspace using a gate.
That means that monitors are used as both system defense ships and gate defense platforms.
The development of the battleship was a direct result of the deployment of monitors which greatly outclassed the frigates and battleriders that existed at that time.
However dreadnoughts and superdreadnouths were a response to the even larger and more powerful forts developed to defend systems.
A fort is a grav powered installation typically grav anchored on the subspace side of a gate or in orbit near the real space side of a gate. With BG engines typically only within the 4 to 6 g range a fort can move only sufficiently to move to its place of station and make a poor target for ballistic weapons (like unpowered missiles.) Because it does not have to mount a powerful BG engine a fort is not limited to 250 million cuft. As a matter of fact it usually mounts more powerful force field armor than all but the most powerful superdreadnought as well as having a massive structural frame supported by structural integrity fields and physical armor as well as internal armor force fields.
Forts also typically mount massive energy weapons, missile launchers (for use in real space) as well a numerous battlerider squadrons. Forts are often located near each other where they can provide mutual fire support.
Like other combat vessels forts deploy either sensor drone nets or purpose built sensor arrays to enhance their abilities to detect incoming enemies.
Enemies who defeat gate defense forts often find themselves facing another layer of defensive positions on the far side of the gate in real space.

Subspace Combat

In subspace combat the nature of the environment makes missiles useless. No matter how good their engines a missile effectively travels no faster than any other vehicle. This makes them easy prey for energy weapons.
Like missiles, railgun projectiles are really just matter enhanced with gravitational engines. They tend to lose momentum quickly and become ineffective at any kind of range.
Energy weapons ranges are drastically reduced, but their effectiveness within their useful range is unimpaired. Typically energy weapon ranges are reduced by 20, that is they are half as effective as they are in normal atmosphere.
Force fields are just as effective in subspace as in real space, but as a gravitic phenomenon are less detectable in the high gravametric environment of subspace. In other words a ship protected by a standard force field is harder to detect. Against the high gravometric background of subspace force field stealth technology is less effective.
On balance this makes it hard to detect protected warships at greater ranges, but distortion fields and masking are less effective at close ranges.
The heavy electromagnet interference in the subspace environment makes long range and active sensors not nearly as good as in real space. This is one reason road beacon stations are seeded so close together and why off road vehicles and ships must depend upon inertial navigation and gravitational topology plotting and can only detect subspace beacons when they are fairly close to the system that has anchored them. This also makes the kinds of weapon ranges seen in real space battles untenable in subspace. Because of the high EM background EM masking and stealth become more effective.
Once away from the beacon stations of the Major Routes and Blue Highways accidentally meeting another vessel is unlikely. So battles in subspace tend to occur at gates or near system beacons. Of course this is where systems concentrate their own defenses when they expect an attack as well as where standard defenses are anchored.

Extensible Hulls

Small craft, such as brakes and HUVs often use extensible hulls to maximize usable space while in space or on the ground, yet allow for a more streamlined shape while transiting atmosphere. Extensible hull craft also allow for smaller hanger footprints while being carried aboard larger craft. They also sometimes allow hull compact enough to use transport portals, a reason many brakes and HUVs are held to 8 ft by 13 ft. cross sections to allow their use in standard 10 ft by 20 ft transport portals.
Slide compartments are skinned in hull sheets made of smart material that can expand to allow the underlying structure to slide out while maintaining an air tight envelope. The use of structural integrity fields allows both greater stress to be tolerated by the sliding section and helps maintain airtight integrity.
