Ok, I'm back.
Point the first. Whatever story reasons aside (feel free to PM me if you want, I don't particularly care about spoilers), I simply don't think the Systems Commonwealth is that powerful.
Let's look at the weapons of a Glorious Heritage Cruiser
The Andromeda Wiki wrote:The Andromeda is, as every ship of her class, designed to be an extremely powerful ship with a multitude of weapon systems, offensive and defensive. She is a heavy cruiser and flagship of the Systems Commonwealth, and is supposed to be the representation of the power held by the Commonwealth.
Andromeda's standard missiles have a 40 mt yield, and reach speeds of 90+ PSL. They also have a 1 kg mass, which is approximately the size of a human fist.
She can fire 8 mps (missiles per second) from each of her 40 ELS Launch Tubes, giving her a total rate of fire of 19,200 missiles per minute. With this kind of firepower, she is able to depopulate a planet in under 2 minutes.
That IS very impressive, yes (those missiles have the yield of heavy shipkillers in something the size of a fist), but I think Thanas is vastly overestimating their effectiveness against SDNW4 ships. Given his stated chosen tactic of firing missiles from lightminutes away, that gives enemy ships minutes to evade or coordinate their point defenses. These are the same ships that evade lightspeed weapons at lightsecond ranges (and in fact, the standard engagement range is under a lightsecond not because of lack of range, but because the difficulty of hitting something further out). Moreover, the Systems Commonwealth is explicitly limited to lightspeed sensors in the show (unless they changed that, I only watched it up till the second season), which would again place the Andromache at a severe disadvantage against SDNW4 ships.
The missiles moving at 90+ PSL is also impressive, but not that unique, considering there are the nearly lightspeed missiles from Tianguo, and actual FTL missiles used by the Eoghans and my own power. Moreover, something that small as a missile from Andromache would be extremely vulnerable to things like proximity hits from nuclear blasts, widebeam or raster fire from point defense, etc. Considering the enemy computers would have whole minutes to designate a fireplan, I can easily see large numbers of these missiles being destroyed before they get anywhere into range. Yes, the sheer number of birds in space, 20k a minute, will be a problem and yes, they would simply overwhelm the point defenses of anything but the largest fleets, but I do not think it would simply swat enemy fleets out space the way it did in the prologue posts.
On the other hand, the Andromache has neither shields nor anything akin to the Sphere of Exclusion, and there are strict physical limits to how much incoming fire a ship can take (and, unlike the Monolith which is fucking huge, the Andromache has hard limits as to how much armor she can carry). Her defensive capabilities would be rather subpar compared her offensive abilities. Overall, I would rate the Andromache's strength to be around 5-8k points, realistically speaking, not counting the fighter complement.
Point the second, it looks like you got tripped up in the carrier rules (so did I, because the wiki is absolutely fucking useless *glares at the mods*). Basically, what the wiki does not say is that a fighter (or a troop) takes up twice it's own size in hullpoints (and yes, that makes carriers more expensive than their attack values). So, 4k points of fighters would require 8k points of hull capacity, not 4k.
Point the third, slipstream's strategic mobility is worth a lot more than 4k points, as Eric explained in his post. Personally, if it were up to me, I would either make it equal to the ship's offensive value, or simply disable it entirely and have the ship towed (or even carried) by other ships. That would reassure the players of its strictly defensive intent, and being stranded inside Sassanid territory would not present that much of a problem as there can always be friendly ships nearby to tow it to safety (and can open interesting story possibilites as the Sassanid fleet prepares an offensive to cover for an attempt to retrieve the Andromache, that is now stranded in what is now behind enemy lines, etc).
Point the fourth, the prologue has this bit.
The missiles were intercepted by defensive missiles before they had even cleared half the distance. And then the offensive missiles launched by the Andromache arrived on target.
The Perseid reserve fleet consisted of 32 top of the line Dreadnoughts, six carriers, 18 cruisers and over 400 frigates. All in all, they had launched nearly 7000 fighters and bombers in preparation for the attack on the Sassanid fleet.
The XMC-class heavy cruiser Andromache Ascendant had 60 missile tubes, each capable of firing 4 independently-targeted missiles per second and double that when launched against the same target, allowing her to fire 14400-28800 missiles per minute. She also had full sensor locks on all Perseid ships, which were to her just a massive array of huge, lumbering targets.
The Perseid fleet barely had time to register the missile swarm heading for them, though the slave-soldiers did their best. They tried electronic countermeasures – which failed as the AI steered the missiles manually. They tried shooting them down – only to discover the missiles were highly maneuverable and flew in a random pattern. The fighters tried to accelerate and run – only to discover that offensive missiles travelled at a speed of 85-95 percent of light speed. Finally, the Perseids trusted in their shields and thick hulls – which proved futile as over 300 volleys of missiles arrived simultaneously on target.
The Nebula lit up as the Perseid fleet was wiped out in less than three seconds.
Two points here. The first is, that if the Perseid ships had powerful enough ECM to fool the missiles at close range, how in the name of the God-Emperor did Andromache managed to "steer the missiles" from lightminutes away with its own suite of lightspeed sensors? Against vastly unfamiliar ECM from an extrauniversal power, no less. Against ships that can dodge and evade railgun rounds and lightspeed weapons at lightsecond ranges. Yeah, right.
The second point is, that if Andromache could steer the missiles, she could also very well steer the fighters, meaning that Thanas's protestations about the lack of pilots are vastly exaggerated.
Point the fifth.
a) Slipstream leaves gravitonic anomalies, so you would know what had happened
Assuming we would know that "gravitonic anomaly= slipstream," which is unlikely
b) The Xenos have no starcharts of other empires
Easily acquired. There IS a lot of intestellar commerce going on, you know
c) The fighters are too valuable and atm irreplacable
They are also small, and fairly easily retrieved by a waiting ship, if one cares to do so.
d) lack of pilots. Currently I think there are about six or so, with another six or so graduating.
Easily corrected in a year or so.
e) I am pretty sure having unallowed fighters appear in other empires is an act of war.
It depends on the fighters, and whether they are detected, which may not be likely, if the scouting is done intelligently.
f) The Xenos have no interest at all in other empires. They do not want to visit them with the ship, they do not want to let other empires know about the ship etc. Having slipfighters appear all over the universe is a great way to call attention to yourself. The xenos would prefer if nobody ever found out about them. Heck, their whole society is built on isolating themselves, even from their own citizens.
Assurances are nice and well, but they have a tendency to go out the window when push comes to shove. I wanted a defensive fleet and I did not give most of my ships hyperdrives. That is hard limits, not assurances. In your case, if the Sassanids are fighting for survival, the Andromache may well end up being used offensively. Simply jumping into an empty system in enemy space, or even deep space would force the enemy to commit something like half their total navy, which can not carry out offensive operations, or even protect their own fleet bases. That is a huge, potentially war-winning advantage and I am very strongly opposed to it.
Have a very nice day.
