Kommer Iran stänga Strait of Hormuz (Hormuzsundet)?

Question: Would several GBU‑43/B MOAB drops be effective against Irans bunkers and defenses near hormuz?

Considering language and approach
I need to ensure the answer is in the same language as the user's question. I could provide a high-level response without going into operational details, which might not require extensive research. I'll also consider discussing the effectiveness of what I'm addressing and include important caveats. It's really crucial for me to avoid giving any targeting advice to keep things appropriate and relevant.
Done
Short answer
Probably not reliably effective against Iran’s deepest/hardened bunkers near the Strait of Hormuz, though multiple GBU‑43/B MOAB drops could damage surface facilities, entrances, roads, antennas, exposed air-defense sites, and personnel/equipment in the open.

The MOAB is extremely powerful, but it is not primarily a deep-penetrating bunker-buster.

Why MOABs would be limited
Factor MOAB relevance
Weapon type Very large blast bomb, airburst/surface burst effect
Main effect Massive overpressure and area destruction
Best against Caves, tunnels with exposed entrances, troops/equipment, light structures, surface infrastructure
Weak against Deeply buried, reinforced bunkers inside mountains or under thick concrete/rock
Delivery aircraft Typically dropped from large cargo aircraft, which are vulnerable in contested airspace
Air-defense environment Iran has layered air defenses, radars, mobile SAMs, and dispersed launchers; using MOABs would require major suppression of air defenses first
Against bunkers
Iran is believed to use a mix of:

Mountain tunnels
Hardened underground command sites
Missile storage and launch infrastructure
Coastal defense positions
Dispersed and mobile systems
MOABs could be useful if bunkers have:

Shallow tunnel sections
Vulnerable entrances
Ventilation shafts or external support buildings
Troops or equipment staged outside
But against deeply buried facilities, the more relevant weapons would be penetrator munitions, such as specialized bunker-busters, not MOABs.

Against defenses near Hormuz
MOABs could have some value against:

Exposed coastal missile batteries
Radar sites
Logistics hubs
Barracks or staging areas
Mine-laying support facilities
Tunnel mouths or cave complexes
However, many Iranian defenses around Hormuz are likely:

Mobile
Concealed
Distributed
Hardened
Embedded in terrain
Protected by air defenses
That makes large, slow-delivered bombs less ideal unless air superiority has already been established.

Major practical problem: delivery
A MOAB is not typically delivered by a stealth bomber or fighter. It requires a large aircraft like an MC‑130-type platform, which would be at high risk unless:

Enemy air defenses were heavily degraded.
Airspace was controlled.
Target coordinates were highly reliable.
The aircraft could approach safely.
In a dense anti-access environment like Hormuz, that is a significant limitation.
