David, this one is project A20PS - search (P=poiskovo) and rescue (S=spasatelniy) variant.

Thanks both.
Is it a prototype?
The other "Project A20PS type Khivus-20" models seem quite different.

Ah, thanks Alex, you just beat me to it.

Alex, an interesting photo, thanks for sharing it with us.

David, I don't think this one has a name, the ID behind the door is "АЭРОХОД" (Aerohod), the manufacturer.
Regards, Rick

It is her builder's name.
Here's a better photo (not mine): https://fleetphoto.ru/photo/289880/?vid=93094
and here's shipyard website: https://www.aerohod.ru/en/

There is an ID or something else written just behind the open door: looks something like AIPOX-- (or AIRUX--)
