(FT) immobile targets vs salvo missiles

Anyone have any good ideas to make immobile units, such as a base, less
vulnerable to salvo missiles? That is, without a full fleet in attendance,
lots of escorting fighters, or nearly its entire weapon outlay devoted to PDS,
since all of this could
be countered by the enemy having more missiles and/or a
bigger fleet? One idea I thought of, only allowed on bases of
x+ sizes, is a jammer-network where only half of the missiles
that get a target lock then lose than lock. Example: 1 salvo, player rolls a
5, so 5 missiles lock onto the target, is then halved to 3 missiles that
actually have to be defended against.

Maybe drives interfere with the jammer-network (and vice-versa)
which is why ships do not have them (PSB reason why some missiles miss). Or,
has a large mass outlay (say 20%?) which makes it uneconomical for ships.

For now, our new campaign does not have to worry about Nova Cannons or Wave
Guns since we're using book ships (have I said how I hate this idea? at least
I'm allowed to replace the single hangar bays from any DNs that I buy).

If you look at the archives for around March and April, IIRC, you'll find
quite a debate on fighter effectiveness. Some of the suggestions will apply to
bases.
