The 37th Wave: Advanced Ballistic Escalation

In what state media describes as the most intense barrage since the conflict's inception, the IRGC has launched the 37th wave of its "Operation True Promise 4." The overnight offensive, lasting more than three hours, involved the deployment of Iran’s most sophisticated heavy missile systems. Unlike previous drone-heavy swarms, this latest salvo relied on high-velocity ballistic missiles designed to penetrate modern air defense umbrellas. The IRGC Public Relations Office stated that the "multi-layered" attack was a direct response to the "unprovoked aggression" against Iranian soil that began in late February.

Specific Targeting of U.S. and Israeli Infrastructure

The primary objectives of the overnight strikes included:

Erbil, Iraq: Multiple missiles targeted Harir Air Base and other facilities in the Kurdistan Region hosting U.S. and coalition forces.

Manama, Bahrain: Ballistic missiles were directed at the U.S. Navy’s Fifth Fleet headquarters. Bahraini authorities reported smoke rising near the facility and characterized the strike as a violation of sovereignty.
