US interceptor missiles launched in support of Israel during Iran's retaliatory attack last month recorded a 25 percent success rate, according to a report by Israel's Army Radio on 1 May.

The report highlights that “only two of eight” missiles launched from US warships in the Red Sea succeeded in hitting Iranian missiles and drones that swarmed the combined defenses of Israel, Jordan, France, the US, and the UK.

On the other hand, Israeli interceptors reportedly achieved a “90 percent” success rate against the Iranian barrage. Tel Aviv claimed its defenses intercepted 99 percent of the projectiles fired during Operation True Promise.

Nevertheless, the claim was discredited by Israeli media days later.

“The interception percentage of the missiles is about 84 percent, a very high percentage but not comparable to the numbers that the IDF provided, which gave the feeling that there had been an absolute interception of all Iranian threats,” Israeli military expert Or Fialkov told Hebrew daily Maariv in an interview last month.

Israel had come under a massive attack from Iran on 13 April in retaliation for the bombing of the Iranian consulate in Damascus two weeks earlier. According to western officials, the Islamic Republic launched 185 drones, three dozen cruise missiles, and 110 ballistic missiles, seeking to overwhelm the air defenses of Israel and its allies.

Iranian President Ebrahim Raisi hailed the Islamic Revolutionary Guard Corps (IRGC) for the success of its operation against Israel, highlighting that Tehran acted alone against Israel and its allies. He also claimed that “over 10 countries” took part in defending Tel Aviv.

“[Operation True Promise] took place even though Iran did not use the element of surprise but came according to a prior announcement. Therefore, the opposing front mobilized all its strength on that day and at the hour of the operation’s implementation to thwart it.”
