Of North Korean design, the IS-120 Ghadir (Qadir) submarine closely resembles the North Korean “P-4 Class”.

Some models of the Ghadir appear to have conventional cruciform tail fins with conventional propeller instead of the North Korean sub’s unconventional control plane arrangement and co-axel twin propeller. Photos of a production boat however show the unusual under-tail hydroplane position as per the North Korean boats. The coaxil twin props of the P-4 is replaced by a single skewed skrew in the usual place, plus a small ducted skrew mounted above, possible steerable. The exact reasoning for the two propellers is not clear but it is likely that the smaller one is intended for slow/quite running and counter-drift. Its mast and unusual snorkel (which folds backwards into the hull -casing when not in use) is almost identical however. It is possible that there are several iterations of boat with varying tail arrangements and snort-mast stowage (some appear to remain above the deck when folded).

Another charactristic which has yet to be explained is a small container mounted externally on the forward deck just ahead of the sail. This resembles an oil drum. One guess might be compressed gas.

Estimates of the size of this submarine vary greatly but video evidence confirms that there's barely enough room to stand up in the hull.


These boats are credible littoral submarines well suited to mine laying, infiltration/Special Forces operation and limited anti-surface warfare. Their torpedo tubes could conceivably carry the Shkval rocket torpedo or even submarine launched anti-ship missiles which Iran reportedly has. But their sensor fit is almost certainly basic by contemporary standards limiting their potential against other subs and advanced warships. There is also no reason to suppose that they are particularly quiet, with no signs of raft-mounting for the engines, or accustic tiling, and the shallow water of the Gulf is likely to leave them exposed to anti-submarine warfare.

Google Earth imagery shows a single midget sub moored in Bandar-e Abbas port in 2005, although this looks more like a Nahong class sub to me. In 2008 imagery there are four submarines however:
