That all depend upon the fighters being available, there is a thing as production limits you know. We even got mass-produced XXL mechs now, your C-bills aren't as relevant as you might think.
The same can be said of the Carrier DS if you were actually successful at interdicting an entire system, and a WS that has used up its charge is also not going to be able to respond. DropShips have the advantage of being able to use a series of JumpShips to travel even faster than any WS could.
If you have production limits on fighters, that's like having production limits on cars. you don't need a massive shipyard complex to build fighters. If you can build PWS (or afford to buy them) you can build fighters in quantity (or buy them).
so no, your hypothesis there doesn't hang together.
Second: Carrier dropships vs. PWS: again, if you can procure PWS, procuring carrier dropships using the same basket of resources comes out far cheaper. This isn't 3024 anymore where the factories are relics of a by gone era that nobody knows how to work on or with turning out magical devices nobody understands.
so those limits are done. If you can afford to build the more advanced thing (PWS require more knowledge than a simple box with airlocks and an engine) then you can build the less advanced things cheaper and in larger quantity.
Which is good, because the less advanced thing happens to be more effective at every job you actually need the more advanced thing to perform except Orbital bombardment, which is a task you really don't need to fill in order to maintain the task of 'defending your system'.
(Palmyra demonstrates why it's arguably not that useful as a tool of offense, either.)
the second point you answered:
Yes. Both carrier dropships and PWS have the same defect there. both can be stranded. Which is why only an idiot sits on a big barrel of money (which the Lyrans apparently still had) without addressing it by building armed jumpships capable of maneuevering.
Especially in a neighbourhood that includes a Clan that never gave up the dream of conquest and
has shipyards.NOte: We are talking about the Lyrans in a FWL thread, but my point is, 'don't be like the Lyrans', who basically put the keys to their kingdom in Devlin Stone's sweaty fingers and did NOT rebuild their shipbuilding industry, but instead relied on a handful of rotting hulks and a lot of imported shipping they can't move strategically, can't repair, can't replace and can't maintain.
PWS doctrine is a
trap. They aren't strategically maneuverable and they cost a lot of money, resources and time compared to more conventional dropship types, but don't give you the same benefits (aside from Orbital bombardment, which is of...limited...utility) as an actual self-moving fleet. They're at BEST good for the static defense in a situation where your talent pool is sharply limited and your risks are short-term and local/self limiting.
They might adequately serve as an
adjunct to a functioning navy capable of serving a state-as assault units attached to a
real navy, but trying to use them
as your real navy will leave you bled dry in short order if you aren't producing a surplus of jumpships.
