Iran says it has "successfully" tested a new ballistic missile that it claims can reach Israel and penetrate some of the most advanced missile-defense systems in the world.
Amid growing concerns in the West over Tehran's advancing nuclear and missile programs, Iran's state TV on May 4 aired footage of the Qassem Basir missile being tested and apparently hitting its target.
Iranian Defense Minister Aziz Nasirzadeh said the solid-fueled missile has a range of 1,200 kilometers and can penetrate Terminal High Altitude Area Defense (THAAD), an advanced anti-missile system that the United States deployed to Israel last year.
Nasirzadeh said the new missile was developed by addressing weaknesses revealed during operations True Promise 1 and 2 -- Iran's missile and drone attacks on Israel in April and October last year.
The minister asserted that the missile had been upgraded in both guidance and maneuverability to help it get through layers of air defense and claimed it was resistant to electronic jamming.
Tasnim news agency, which is affiliated with the Islamic Revolutionary Guards Corps (IRGC), said Qassem Basir is an upgraded version of the Martyr Hajj Qassem missile, which was named after slain IRGC Quds Force Commander Qassem Soleimani and unveiled in 2020.
The missile was unveiled on the same day that Iran-backed Houthi rebels in Yemen launched a missile attack near Israel's Ben Gurion Airport, injuring several people and briefly disrupting air traffic.
Israeli Prime Minister Benjamin Netanyahu blamed the attack on Iranian support for the Houthis and pledged retaliation against both the Yemeni group and Tehran.
The missile notably evaded sophisticated air defense systems. Israel is said to have had two THAAD batteries and at least one Arrow 3 interceptor system in operation at the time of the attack.
Experts say the Qassem Basir missile marks the first usage by Tehran of optical seekers on a medium-range ballistic missile.
Russian-based weapons expert Yuri Lyamin noted that the new medium-range ballistic missile was now Iran's "most long-ranged" missile equipped with electro optical (EO) seekers, replacing the short-range ballistic missile Zolfaghar Basir.
Fabian Hinz, a researcher at the International Institute for Strategic Studies, explained that -- in theory -- this missile uses its own camera to navigate by matching what it sees against stored visual information. This means there's no external radio signal to interrupt, making it effectively jamming-resistant.
Hinz told RFE/RL that the accuracy of Iranian missiles that struck Israel, especially last October, "was not great." He attributed it to potential signal jamming, which is what prompted Iran to work on developing missiles that use EO seekers.
Nasirzadeh warned that any military aggression from the United States or Israel would prompt a global response targeting their assets and bases.
He stressed that while Iran does not seek confrontation, it will respond "firmly" if challenged.
