**You're spot on with your assessment—**
Iran's ability to move any meaningful amphibious force (whether to reinforce Kharg Island or to counter a potential US landing there or along the coast) is extremely limited, and the ongoing conflict has made it effectively negligible.
Here's the breakdown based on pre-war inventories, recent conflict damage, and geography:
Pre-war amphibious assets (very modest to begin with)Regular Iranian Navy (IRIN): About 23 amphibious units total, per standard references like The Military Balance. This includes:3 Hengam-class LSTs (small tank landing ships).
3 Farsi-class LSMs (medium landing ships).
6 Fouque-class logistics landing ships.
A handful of smaller LCTs/LCUs.
~8 hovercraft (Wellington Mk 4/5 and Tondar types, based on older British designs).
IRGC Navy (the more asymmetric branch focused on the Persian Gulf): Only ~5 dedicated amphibious vessels listed, plus a few converted logistics ships (e.g., Shahid Mahdavi or similar "mother ships" that can carry small boats, drones, or helicopters but aren't true assault platforms). They rely heavily on fast attack boats and a few hovercraft for short-range insertions.
These aren't US-style assets—no large LHDs, no LCACs in meaningful numbers, no capacity to land thousands of troops with heavy equipment in one wave. A single Hengam-class ship might carry a couple hundred troops plus a few vehicles at most. Hovercraft are useful for quick hops but carry even less and are highly vulnerable. Total lift for a coordinated operation? Probably a few thousand troops at absolute maximum, spread across multiple vulnerable ships—nowhere near what the US Marine Expeditionary Units (with their LHDs, well decks, Ospreys, and AAVs) can project.
Kharg Island specifics make it even less feasible
Kharg is only ~20–25 miles off the Iranian mainland (near Bushehr). In peacetime, Iran could theoretically shuttle small numbers of troops there via small boats, civilian ferries, helicopters (Mi-17s or similar), or even the island's own port facilities. No deep-ocean "amphibious assault" required.But that's the catch: under current conditions, it's still a non-starter for anything beyond tiny, high-risk groups:The short distance doesn't fix the equipment shortage or vulnerability.
Any movement would be in contested waters/airspace with US carriers, destroyers, and now-deploying amphibious groups (USS Tripoli, Boxer ARG, etc.) dominating the Gulf.
Ports, bases, and coastal facilities around Bushehr/Bandar Abbas have been repeatedly struck.
