“Mk 48 ADCAP”?
What about something else like the battery driven DM2A4 “Seehecht” with fiber link?

The MK 48 still runs on a piston engine. A piston engine works with gas pressure and that pressure works against the surrounding pressure of the water. At a given depth a piston engine can’t work. A diesel engine provides about 200 bar working pressure. So a diesel engine can not provide any power at depths over 2,000 m. I guess a swashplate engine offers less pressure.

Propulsion power of an electric engine powered by a battery is not related to static pressure. I guess there is a reason why Yasen-class submarines have a test depth of 600 m. It could be possible that these submarines can outrun the MK 48 at such depths.

There is a reason why electric cars need an additional sound system to warn the pedestrians. An electric motor is to quiet for pedestrians.

Does the MK48 ADCAP Mod 7 already has a fiber backlink to the submarine as once proposed?

The ADCAP Mod 7 just has a broad band sensor while the DM2A4 also has a wide wide panoramic sensor angle ( +/-100° horizontal and +/-24° vertical). Together with the fiber link the torpedo works as a forward positioned sonar system for submarine’s combat system.

Sorry if I led you down a primrose path by referring to the Mk 48 ADCAP torpedo... I was expounding the idea that "something" always beats "nothing", and that quantity is a quality all its own... A concept current in Russian military circles, so I hope you'll approve as well.

To speak a moment more of torpedoes, several services responded to the retirement of the U. S. Mark 46 lightweight torp by bringing forward new designs of their own. This is a situation analogous to the withdrawal of the FF/FFG type at the platform level. We ought to emulate those services which designed around the disappearance of the Mk 46 by adopting a similar expedient policy of adopting available designs, even if they are not homegrown, "copacetic" solutions. I mentioned the Type 23/26 as a possible replacement for the current frigate types in the US inventory.

The Royal Navy in 1914 was a cruiser navy. At the end of World War I, they possessed some 71 light cruisers in the 3500-4500 ton range and a few "large" light cruisers in the 6000-ton range. Their big ships were famous and their heavy cruisers imposing, but it was the small cruisers that made the Royal Navy a blue-water, "everywhere" navy.
