Interesting statement. So asymmetronics also think that Ghadir-sub is equipped with C801/YJ8 Q?
Yes, Ghadir's tubes seems to be the right diameter but, as has been pointed out in IMF, there's not much room left for spare missiles. You could temporarily attach them to the outside of the hull (and even launch them from there) but it would compromise the sub's stealth profile and reduce its chance of escaping after an attack.
Besides, the sub will have problems acquiring and illuminating mobile, "over the horizon" targets with a
long rang missile (whereas a
shorter range missile would again, make escaping more difficult). Here's where a (stealth, VTOL) drone would come in handy!
Stationary, predesignated targets wouldn't be a problem of course. The sub would in fact act as a -hopefully reusable-
range extender for the missile.
