Q: How does a solid rocket fuel compare to liquid fuel as far as
specific thrust versus density of loading?
I can see why the two exotic torp oxidizers/monopropellants I am
familiar with, propylene glycol dinitrate and hi-test hydrogen
peroxide, are not 'sub-friendly' but I don't know how either would
compare to say ammonium perchlorate/aluminum/hydrocarbon solid fuel.
Looks like powered duration on Skval is about 90 seconds max.
Launching it will surely give a very noisy sound signature and a fix
if there's more than one searcher close by - on its origin.
If it is used against a formation it looks like there would be a trade
- one sub for one target.

In strategic terms that might be a good trade. Tough on the crews,
though.
