Iran has developed the Khorramshahr medium-range ballistic missile, a weapon capable of carrying a heavy warhead [1].

The development of this system represents a significant escalation in the Islamic Republic's deterrence capabilities. By increasing the payload capacity of its missiles, Iran enhances the potential impact of strikes against regional adversaries, including Israel and U.S. forces [2].

The Khorramshahr is classified as a medium-range ballistic missile, or MRBM [1]. According to technical data, the missile can carry a warhead weighing between 1.5 and two tonnes [1]. Some reports specify the capability at approximately two tonnes [2].

General Ali Mohammad Naeini and other officials have overseen the missile development program, which utilizes testing facilities within the country [2]. The program aims to ensure that Iran can project power effectively across the region.

"The Khorramshahr missile’s heavy-warhead capability makes it one of the most potent MRBMs in Iran’s arsenal," a WION presenter said [1].

International observers remain concerned about the stability of the region as Iran's arsenal grows. Michele Kiley said that Iran’s missile programme remains a serious threat to regional stability, even if some of its claims are exaggerated [2].

The ability to deliver a larger payload allows for more destructive conventional explosives, or a greater variety of warhead types. This capability complicates the defense strategies of neighboring countries, who must now account for higher-tonnage impacts.

The deployment of the Khorramshahr missile signals a shift toward higher-yield conventional capabilities. By focusing on warhead mass rather than just range, Iran is increasing the destructive potential of each individual launch, which may be intended to pressure regional opponents into a more cautious diplomatic posture.
