Makes me wonder what the SEAWOLF guys call this boat. “Bait”, maybe?
I think that might be the boat’s stealth speed. It can go faster, but when it does, it makes more noise and is easier to detect.
An electric boat operating stealthily is almost impossible to detect by passive sonar. You can ping on it, but that sort of defeats the purpose if you are trying to be sneaky.
These new air-independent propulsion systems are scary. WE should be building them, but aren’t. With them, a non-nuclear boat has far greater underwater range than they ever had before.
The USN is going to severely regret gutting its ASW in the days after the collapse of the USSR. It was a dumb move.
I wish people would stop making stupid jokes about China’s growing naval capacity, especially its sub force. They’re real, they’re serious, and they have already proven the can penetrate a CVBG screen before.
