US Military News, Reports, Data, etc.

Conventional subs cruise speed is somewhere around 5 knots while a battle group's cruise speed is more than 15 knots. A conventional sub's sprint speed may reach 20 knots, but it can only endure only 20 minutes before the batteries runs out and have to surface to snorkel in which it can be detected by surface radar.
So NO, a conventional sub Chinese or not can not trail a carrier battle group, BUT it can lay low and calculate the sea current and vector of the carrier group to slip in and out which really takes skill and knowledge with a little luck.
Japanese MSDF subs have been known to slip out of a carrier strike group during anti sub wars exercises using this technique after gaining kill marks.

quote of the day comes from inside of https://breakingdefense.com/2019/09...77.1508926729.1568054768-329840437.1535217933
Esper Starts Setting Up DoD-Wide ‘Night Court’
:
"Time will tell how much Esper can find to save in the massive bureaucracy of the Defense Department, and what Capitol Hill, with its local interests, has to say about the effort."

 

actually it's a good question if the USN is still able to find a sub in for example https://en.wikipedia.org/wiki/Lower_New_York_Bay

I haven't seen any recent picture of Burkes towing sonars, doing spring and drift if you know what I mean (now go ahead, tell me of their HMS, the Poseidons)

the OHPs were hastily retired

so that LCSs could, ehm, shine = filling the ports and feeding shipyards, the USN talking revolutionary transformational game changing capabilities

I guess the situation is even worse for minesweeping: there're 11 (eleven) Avengers left!!

I am not so concern about the technical aspect but the concept of operations. With flying drones, you either blow it out of the sky or spoof it to hijack the drone like what the Iranians did. What is stopping the Iranians or anybody else to sail along it, board it, disable the systems and hijack it? With a manned vessel you don't have such a problem to deal with.
