Chinese Unmanned Underwater Vehicles (UUV)

by the way @BoraTas notice how humongous the battery section is? Given the density of the section, that's easily 1/3 of the weight of the UUV. Could be even 40%

Reminds me of this sailess small sub a while back.

If Li-Ion, that UUV would have a lot of endurance. Possibly over a month in low speeds.

The scale is 1:38 so maybe someone can get a rough estimate of the actual size of that thing. I feel the scale model is easily over 1m long.

More images of that new UUV.

I wonder, what would justify that hump, if the access hatches are in front and aft of it.

I would've expected a larger spherical shaped sonar in the front.

Other than that, pretty much what's expected of XLUUV.

for a 300t UUV, if 40% of weight is battery. 120t x 250kWh/t = 30MWh

If they can get SSB in there in a few years. 120t x 500kWh/t = 60MWh

IIRC, the hotel load of AIP is about 200kW for hotel load + 4 knots speed. Since UUV is much smaller and doesn't need to support crews, it would be much less than that). Maybe 30 to 40 kW?
