What if it's a UUV, carry a bunch of AQS003As in some special dispersal modules similar to VLS? Just downward not upward
It can also be an "anti-submarine specialized" submarine, just in a different way.
While it's possible that it is a UUV in theory, given the huge size of this vessel it would be the world's largest UUV by magnitudes, and thus somewhat lower on the list of possibilities imo.
The alternative explanation of it being a manned submarine with a small profile sail, imo is much more likely.
(Being a manned submarine can still allow it to have special dispersal modules btw)
A bit of an odd image.
The proportions don't look like a 10m x 120m submarine (even accounting for partial obscuration by the crane).
The proportions look slightly more 09V-ish than anything, though even then I'm not sure if it lines up perfectly.
It's also unclear if there is definitely a sail or no sail, and it's also unclear if it looks like there is a slight minor hump along the middle segment of the hull.
Odd
