These small boats are fine for swarming isolated or civilian ships, and the first VLS usage is interesting, but I am far more interested in Iran producing a fleet of 10-20 Shahid Soleimani class ships with 150km range Sayyad-3 SAM and 1000km range Abu Mahdi ASCM to patrol the Gulf of Oman and Northern Arabian Sea.
Even with 12 of these patrolling the Persian Gulf down to the North Arabian Sea, look at the A2/AD and anti-ship range capabilities (black circles = 150km Sayyad-3, red circles = 1000km Abu-Mahdi ASCM):

Then add to this a fleet of VLS Mouj frigates (developing at a painfully slow speed), the large ships serving as forward bases/support ships (with great offensive capabilities, such as SRBMs and UAVs), 20-30 Ghader midget subs in the Persian Gulf and Gulf of Oman, 4 Fateh subs (also developing very slowly) and 3 Kilo subs patrolling the Gulf of Oman and north Arabian Sea, existing AD systems on Abu Musa and other Iranian islands, coastal ASCM/ASBM hidden under mountains ... etc. Multiple layers of AD and offensive capabilities.
The US would be forced to strike from the Mediterranean or Red Sea. And there the newest ASBM assets with a 1500-2000km range can come into play too.
