The exact nature of development pathways for #PLAN SSN #submarine design remains uncertain. This picture is a good illustration re the various suggested types, though a very good (if older) report alternatively assumes three variants, see here:

FWIW it seems most probable to me there are four variants, the original 093, straight sail, no TAS, the 093A (smooth sail root, no TAS), an 093B with a notable hump, potentially used with a dry deck shelter & TAS + sail mod, and the final 093B with minor bumb,TAS sail mod. https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤷‍♂️" title="Man shrugging" aria-label="Emoji: Man shrugging">

Still among the more interesting shots of 093 is this one with aforementioned DDS. From imagery it seems unclear what sub-type we see. Pics via SDF "Tam".

And the 093 with pronounced hump vs very slight smooth hump.

Lastly photos corresponding to OP scheme. https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤷‍♂️" title="Man shrugging" aria-label="Emoji: Man shrugging">
