ISLAMABAD: Iran stands on the verge of securing a major arms agreement with China for the acquisition of CM-302 supersonic anti-ship cruise missiles, a development that could significantly enhance Tehran’s naval deterrence capabilities in the Persian Gulf.
Multiple sources familiar with the negotiations, cited by Reuters, confirmed that the deal involving the Chinese-made CM-302 missiles is nearing completion. However, key details such as the delivery timeline remain unresolved.
The prospective transfer comes at a time of heightened geopolitical friction. The United States has deployed substantial naval forces near Iranian waters, including aircraft carriers, in anticipation of potential military operations against the Islamic Republic.
Negotiations for the missiles reportedly began at least two years ago. They gained significant momentum following the 12-day war between Israel and Iran in June 2025, which accelerated military cooperation discussions between Tehran and Beijing.
Senior Iranian officials, including Deputy Defence Minister Massoud Oraei, travelled to China last summer as talks entered their final phases. This high-level engagement underscores the strategic priority attached to the acquisition.
The CM-302, an export variant closely related to China’s domestic YJ-12 missile, represents one of the most advanced systems potentially transferred to Iran in recent years. Developed by the China Aerospace Science and Industry Corporation, it features supersonic speeds and sea-skimming flight profiles.
Experts describe the CM-302 as exceptionally difficult to intercept. Its terminal phase involves low-altitude, high-speed approach, reducing reaction time for shipborne defence systems like those on US Navy vessels.
The missile’s reported range stands at approximately 290 kilometres. This allows launches from coastal positions or vessels to threaten targets across much of the Persian Gulf and parts of the Gulf of Oman.
In comparison, many conventional subsonic anti-ship missiles offer shorter effective ranges and lower speeds, making them more vulnerable to modern interceptors such as the Aegis system or SM-2 missiles.
The CM-302 employs active radar terminal guidance combined with BeiDou satellite navigation. It can receive mid-course updates via data-link, enhancing accuracy against moving maritime targets.
A typical warhead weighs around 250 kilograms, sufficient to inflict severe damage on large surface combatants or disrupt commercial shipping lanes.
Defence analysts note that supersonic anti-ship weapons compress engagement windows dramatically. Ships may have only seconds to detect, track, and neutralise incoming threats travelling at speeds exceeding Mach 2 in terminal flight.
Iran’s existing arsenal includes indigenous anti-ship systems like the Noor and Ghadir families. Adding the CM-302 would introduce a qualitatively superior layer to its anti-access/area-denial strategy.
This capability aligns with Tehran’s long-standing doctrine of asymmetric warfare in maritime domains. It aims to deter external intervention by raising costs for adversary naval operations.
The deal occurs against the backdrop of reimposed United Nations arms restrictions. Sanctions initially imposed in 2006 were suspended under the 2015 nuclear agreement but reinstated in recent years.
China has consistently rejected allegations of violating export controls. Beijing maintains strict oversight on dual-use technologies while pursuing deeper military ties with Tehran.
Annual joint naval exercises involving China, Iran, and Russia further illustrate this growing alignment. Such cooperation includes shared maritime drills in the Indian Ocean and Gulf regions.
An Iranian foreign ministry official, speaking to Reuters, emphasised that military agreements with allies are timely given current pressures. No official confirmation has emerged from Tehran or Beijing.
The White House has not directly commented on the reported negotiations. Officials reiterated President Donald Trump’s stance on pursuing tough measures if diplomatic solutions fail.
The potential acquisition raises concerns over escalation risks in the Strait of Hormuz. This chokepoint handles a significant portion of global oil transit, making it sensitive to disruptions.
Commercial shipping could face increased threats if Iran integrates such advanced missiles into its coastal defence network. This might compel international navies to adjust operational patterns.
While the exact number of missiles involved remains undisclosed, the transfer would mark a milestone in Sino-Iranian defence collaboration. It builds on prior technology exchanges despite international scrutiny.
Regional observers warn that the CM-302’s deployment could alter naval power dynamics. It complicates planning for any potential US-led operations in the area.
The absence of a fixed delivery schedule introduces uncertainty. Factors like sanctions enforcement or shifting diplomatic calculations may influence finalisation.
Nevertheless, the proximity of the agreement signals deepening strategic convergence between Iran and China. This occurs as both nations navigate complex relations with the West.
The development underscores the evolving arms landscape in the Middle East. Advanced conventional weapons increasingly shape deterrence postures amid persistent tensions.
