One of Iran’s most advanced missiles made an appearance in its massive attack on Israel

The Fattah-1 is a medium-range ballistic missile considered one of the most advanced in Iran’s arsenal. It was unveiled in June 2023 and can travel nearly 900 miles while carrying a warhead that weighs between 770 and 1,000 pounds. Tehran describes the missile as hypersonic.

Shaan Shaikh, the deputy director of the Missle Defense Project at the Center for Strategic and International Studies, told BI that many long-range ballistic missiles reach hypersonic speeds in their terminal phase. This means they travel at Mach 5 — five times the speed of sound or over 3,800 miles per hour — or faster.

However, true hypersonic capabilities are based on more than just speed and depend on whether the missile can sustain that extreme speed and maneuver effectively during flight. It’s unclear as to whether the Fattah meets all of the criteria, but it does appear to be able to maneuver in flight.

Farzin Nadimi, a senior fellow at The Washington Institute for Near East Policy and an expert in Iranian security and defense affairs, told BI that there are indications that Iran launched a large number of Fattahs in the attack, adding that photographic evidence of fallen debris revealed characteristics consistent with the missile.

Tuesday’s attack, however, saw Tehran fire significantly more ballistic missiles and leave out the slower weapon systems this time around, in turn reducing Israel’s warning time as the ballistic missiles took just minutes to arrive.

“It is the number of missiles that are incoming — the saturation effect of the vast quantity attacking certain locations within a limited amount of time — that makes it very hard for defenses to intercept them,” Shaikh said of Tuesday’s attack.

The Israeli military said that a majority of the missiles were intercepted by Israel and a defensive coalition led by the US, including American warships stationed in the Eastern Mediterranean Sea. Still, some of the Iranian missiles managed to impact on land, although they did not appear to cause significant damage.
