Another one possible Habarovsk with two submarines of "Som" type/project. About the whole line of the type: https://ru.wikipedia.org/wiki/%D0%9F%D0 ... 0%BC%C2%BB

I can't say that this is exactly Khabarovsk. But at first glance, the ship that is shown in your picture is quite similar to the images that I found on the Net. Also, you can read about the history of the ship here (again in russian): http://www.retroflot.com/dobrovoljnyj_flot/tovaropassazhirskij_pa...

Probably the tall man, who appeares in front line on several pictures could be the captain of Habarovsk. I think that it is Maksimov Evgeny Alexandrovich, who was the captain of Habarovsk from 1913 up to 1915. Also you can find some information about him here: http://wunderwafe.ru/WeaponBook/Ushakov...

Yes, he was the last captain of the submarine "Bars" which was sunk on 25.05.1917. Here are some brief words about him in russian: http://www.mke.su/doc/ILYINSKIY%20NN.html

The person in the middle is Il'inskiy Nikolay Nikolaevich - the captain of the submarine Bars.

On the "fifth" picture (on the deck) ерфе shows a group of officers, as well as women and children, near Schiller there is standing Sergey Vlasiev (seventh from the left) - the captain of the submarine Akula.

The second officer from the bottom (with the George Cross of fourth degree) is Vasily Merkushev, the captain of the submarine Okun.
