After all an ERM seems to have 50% more runtime so it should need 50% more power; which (baring any tech breakthroughs) requires 50% more capacitors. And yet, as you said, they're still capacitor powered.
But they are definitely bigger that SDMs. As an aside I guess it's not impossible that a CA weight ERM (the Mark 14) could be small enough to easily be modified to work in an unmodified capital ship's magazines, loading hardware, and launchers; but we've seen no direct evidence that it can be. And it would certainly be a reduction in warhead power compared to SDM capital ship missiles. But I can't see anyone with real MDM tech bothering; better to focus on ships that will be useful in the longer term.
I've been a proponent of an HERM for awhile, but when you look at the timeline, it just does not make sense for Manticore to develop it.
The ERM is first seen in 1917 on the Sag-B CA. Obviouslyit was under development for several years, but the at this time the MK 41 MDM already exists and is installed in launchers in the Minotaur, Hydra and Medusa classes. In the interwar period, plans and mande and work is started to upgrade the Gryphon (and possibly Sphinnx) SDs to fire the Mk 41s (or possibly the later, but smaller mk 23 fusion missiles.) Janacheck, with all the time in the world and money being siphoned off to fund his political master's projects, doesn't rush the upgrades.
In short, between the wars, there is no need for the HERM. The SDs are being upgraded to MDMs or destroyed.
September 1919 - Thunderbolt. Manticore needs to return all it's SDs from the Mothballs. A giant build wave to replace them with podlayers on an almost 1 for 1 basis is started
Christmas 1921 - all the python build is to be complete - the RMN should be able to field ~300 SD(p)s, and builds from allies will add > another 300 SD(p)s to the wall of battle, if not for the loses at BoMa.
In short, Manticore has less than 2 year to identify the overwhelming need for a HERM, design it produce it and build it in worthwile # - all while knowing it is still a 2nd rate weapon and will be useless in less than 24 months.
Plenty of reasons NOT to build the HERM during the 2nd war.
