The operation involved one of Israel’s most advanced and lethal weapons: the MPR-500 guided bomb, designed to penetrate fortified underground bunkers.

According to a detailed report by Army Recognition, Israeli F-15I "Ra'am" and F-16I "Sufa" jets participated in the strike, deploying multiple MPR-500 bombs equipped with precision guidance systems such as JDAM, Lizard, and Paveway II. The bombs were aimed at sensitive Iranian nuclear sites, including hardened underground uranium enrichment facilities, as well as command and control centers.

Developed by IMI Systems (now part of Elbit Systems), the MPR-500 is a 227-kilogram bomb known for its pinpoint accuracy and exceptional bunker-penetrating capability. It can pierce over one meter of reinforced concrete and disperses over 26,000 deadly fragments across an area of roughly 2,200 square meters.

This strike marked a strategic shift in Israel’s military doctrine, focusing on maximum precision with minimal collateral damage. It was part of a broader operation reportedly code-named “Operation Lion's Resolve,” which has so far targeted over 100 sites across Iran, including in Tehran, Natanz, Isfahan, and Tabriz—many of which are believed to host nuclear and military assets and top Islamic Revolutionary Guard Corps (IRGC) commanders.

Military analysts say Israel's use of the MPR-500 bomb carries both tactical and psychological implications, sending a clear message about Israel’s ability to hit deep targets inside Iran and its resolve to halt the nuclear threat.

Iranian state media has acknowledged damage from the strike but has not provided specific details. Tensions in the region remain extremely high, with growing fears of further escalation.
