As I thought, a derived unit of a commercial ship (question which ship was it, is it new made in Iran, a ship that was already sailing under the commercial flag of Iran or bought in the second-hand market?)
The presence of anti-ship missiles, drones and even more interesting that they would use the Khordad self-propelled anti-aircraft.
However I think they have not yet completed the transformation work.
Certainly in the future at least the CIWS 30mm will be installed.
I don't see any fixed crane on the deck to be used for handling loads, or for putting boats in the sea, ok probably as written by others they can be put into the sea from the stern, but the cranes can still be useful; sure they could use cranes installed on trucks, but it would be just a fallback.
I am surprised that there is no hangar above the deck to support the or the helicopter;
Maybe they park them on the lower deck?
but I don't see elevators, maybe they can get the AB-212 off the slide, but that's probably not possible with a Sikorsky SH-3D.
However interesting ship.
