Nope, even the original discussion of MDMs back in In Enemy Hands talked about "let it ride a ballistic course to a preprogrammed attack range", and that was definitely the original capacitor powered missiles.Loren Pechtel wrote:kzt wrote:The wedge on a missile does not start in the launch tube. At least not more than once per ship. The capacitors bring up the wedge once it has appropriately separated form the launching ship.
But they're very limited in how much drift time they have. Only missiles with microfusion plants have meaningful drift time.
Honorverse military grade capacitors pretty clearly don't suffer problematic drain over combat timescales. If a missile could bring up it's wedge a second after launch it appears equally capable of doing so 30 minutes or more later.
Now capacitor powered recon drones do have significantly less endurance than their micro fusion powered counterparts. But it's the difference between half a day and the better part of a week. That's just because the micro-fusion plant plus lots of fuel is more compact that anything close to an equivalent bank of capacitors; it has nothing to do with how long each could hold that power if not actively being used.
