MS200.

This is coolbert:

Midget submarines. Chinese PLAN style. Undersea force multiplier.

As it was Pearl Harbor [1941 so can it be too San Diego 2021??

Midget submarine attack as a prelude to war.

"China reveals new midget submarine design: MS200"

Thanks again to H.I. Sutton the specifications of the MS200:

"MS200 Specification

Displacement: 200 tons surfaced

Length: 30 m

Width: 3.6 m hull diameter

Height: 4.4 m

Crew: 6 + 8 PAX [PAX = passengers?]

Range: 1,500nm, with 120 nm on batteries

Endurance: 15 days

Speed: 8 kt max

Operating depth: TBC [to be confirmed]

Armament: 2 x 533mm torpedoes"

That RANGE severely limits of the MS200 for sneak attack on Pearl Harbor or San Diego. MS would have to be carried by a much larger submarine to the scene of the action, as were the Japanese midget submarines at Pearl Harbor, 1941.

Those two torpedoes probably better replaced by smart naval sea mines? Passengers consisting of naval commando combat swimmers equipped with limpet mines a possible.

For wealthy dot.com billionaires I imagine a midget submarine would make an unusual pleasure craft.
