Iran is set to conduct a missile drill on Thursday as Iranian Foreign Minister Abbas Araghchi warns that the reimposition of UN sanctions on Iran would mean the end of European involvement in nuclear negotiations.

Abbas Hassani, the spokesperson for Iran’s naval forces, said the operational phase of the Sustainable Power 1404 missile exercise will run for two days in the northern Indian Ocean and the Sea of Oman, according to Iranian state news agency IRNA. The drill will include surface and subsurface units, flight units, shore-to-sea and sea-based missile sites as well as electronic warfare forces. 

According to Hassani, Iran will test a wide range of precision cruise missiles with short, medium and long ranges, attacking and destroying floating targets. 

Hassani framed the exercise as part of Iran’s broader strategy of deterrence, citing military readiness, boosting morale and demonstrating Iran's domestic defense expertise. 

Separately, speaking to reporters in Tehran on Wednesday, Iranian Defense Minister Aziz Nasirzadeh said that Iran has "much stronger" missile capabilities than have yet been used. He added, “The missiles used in the 12-day war were manufactured by the Ministry of Defense a few years ago,” saying that today, Iran possesses missiles “that have much better capabilities." 

During its war with Israel in June, Iran launched an estimated 550 ballistic missiles and more than 1,000 drones at Israeli territory. Ahead of the war, Iran's ballistic missile stockpile was estimated at more than 3,000 missiles. 

In July, Yahya Rahim Safavi, a senior Iranian military commander and adviser to Iranian Supreme Leader Ayatollah Ali Khamenei, said that Iran has "produced several thousands of missiles and drones, and their place is secure.” It was unclear whether Safavi was referring to weapons solely produced after the war. 

The New York Times, citing US and Israeli officials, reported in June that Iran had "depleted" its stockpile of medium-range missiles.
