The United States has deployed its latest and second-most-powerful bunker-busting bomb, the GBU-72, against fortified targets in Iran, marking its first combat use. The strikes targeted sites along the Iranian coastline near the Strait of Hormuz.

Key Insights

The U.S. Central Command confirmed the use of multiple 5,000-pound deep penetrator munitions on hardened Iranian missile sites on March 17.

The GBU-72 replaces the older GBU-28, offering enhanced lethality for penetrating deeply buried and reinforced underground targets.

The targeted Iranian sites reportedly housed anti-ship cruise missiles, posing a threat to commercial shipping in the Strait of Hormuz.

The GBU-57 Massive Ordnance Penetrator remains the most powerful bunker-buster in the U.S. arsenal, carried exclusively by B-2 Spirit stealth bombers.

In-Depth Analysis

On March 17, 2026, the United States military employed the GBU-72 Advanced 5K Penetrator bombs against Iranian missile sites. These sites were located along the Iranian coastline near the Strait of Hormuz and were believed to contain anti-ship cruise missiles, posing a significant threat to commercial shipping in the area.

The GBU-72 is designed to penetrate deeply buried, reinforced underground targets, such as missile sites, command centers, and nuclear facilities. It replaces the GBU-28, a 5,000-pound bunker-buster bomb first used in 1991 during Operation Desert Storm. The GBU-72 is considered substantially more lethal than its predecessor.

While fighter jets and bombers can carry both the GBU-72 and GBU-28, the GBU-57 Massive Ordnance Penetrator remains the most powerful bunker-buster in the U.S. arsenal. Only U.S.-made B-2 Spirit stealth bombers are capable of carrying the GBU-57s, which weigh over 30,000 pounds.
