Wow! Thank you Jim!
It will be interesting from our public view how this SSGT concept develops. The triangular hull cross section is a good compromise in total wetted area drag vs. surface running stability (rolling). Also perhaps beneficial from a stealth anti echoic stand point too? The necessary tall 'fin' looks a bit awkward. A bridge watch during high speed surface transit on this 'fin' would be interesting if not exhilarating! The Y stern implies digital, but with a not too complex manual back up. The stern control surfaces aft of the pump jet shroud would make maneuvering incredible to say the least. Question is would this shroud use pump jet geometry or Kort nozzle geometry or a combination of both? Silent submerged operation would be required, AND efficient surface running too. This goes back to earlier diesel submarine propellers that needed to be a compromise for both good surface running performance and operation at depth.
Such (PJ) shrouds on a 'conventionally powered' submarine in current thinking I thought would be concidered awkward, as the submarines source of submerged propulsion energy would be limited to fully exploit the PJ's higher silent speeds it offers. Difficult to state here 'fuel cells' as conventional. This may imply here too that fuel cells will soon in the near future (10-15 years?) offer longer underwater endurance AND at higher operational speeds ....not matching, but approaching current nuclear submarine performance?
