How much Aerospace is too much against WarShips and DropShips?

[AlphaMirage]

I disagree. The main defense of large craft is range, not necessarily armor, short range with Capital weapons is massive even taking into account vector movement, which should be the standard. Fighters have to shoot through that +3 ECM curtain at their medium to long ranges so most are better off being evasive until the last minute or else die from the bracketing or AA fire.

It is really a shame that the designers of the warships we have didn't fill out FC slots with standard weapons. Triple or Quad turrets of ERLL, LPL, or standard PPCs (or all three) are a miniscule mass and heat for a warship particularly against their most irritating foe (you can also use them close range against Warships too). Few Aerospace fighters or even small craft can carry or withstand that much firepower for long. The sub-caps are even better, SCLs in particular are murder on  fighters extending the sphere of engagement quite a bit.

The other thing armor has going for it is that its the lightest thing you can add.  Take any amount of standard scale weapons (and HS) and compare that to how much armor you'd add.

I'm romantic hoping the ilClan Star League will build something of modest fleet of new new designs for the SLDF(C) (Clan)?

to fight what?  Who or whom re they going to need it against??  Nobody's even recovered from the damage of the Jihad, never mind built a fleet of any sort worth the effort, and warships are expensive.  The Republic just demonstrated that a pocket-warship navy is completely ineffective if they don't have complete surprise, and the number of yards capable of servicing, never mind building, such a thing outside of Wolf hands can be counted on one hand with fingers left over, and none of those exist in any place which has enough of an economic or industrial base to support even building ONE ship.

so, why would the project be pursued? it's not like anyone out there can pull something useful out capable of challenging, never mind opposing, the fleet the ilClan already has.

and they're not going to be able to, either.

It's a structural matter.  Nobody has an actual, organized, professional navy-not even the really long-term established states, not even if you discount warships in their entirety and just go with jumpships and dropships and fighters.

They have relic collections instead, and those relics aren't in good shape, and are under the control of people who consider the entire task to be kind of a joke, and it's not just the Clans or the Republic who see it that way, everyone (and I do mean everyone in the canon sees interstellar nations as functioning like planetary provinces with contiguous land-masses, so nobody  has invested in building a working, functioning, navy to do working, functioning Navy things.  The best ones are basically a railroad service in how they operate, the worst aren't even that far advanced structurally or organizationally.  Thus, why you have people operating with the idea you can defend a star system from a fixed point right outside the established jump points.

so there's no need for new warships for the ilClan, and there's no narrative support to allow it.
