Israeli military officials and Mossad operatives have been shocked by how quickly key Iranian military capabilities are being restored, only months after the 2026 US-Israeli war of aggression.
The development has raised fresh alarm in Tel Aviv over Tehran’s ability to rebuild its missile forces and other strategic systems.
According to a report in Israel’s English-language daily The Jerusalem Post, citing Israeli sources, military and intelligence officials believe Iran has discovered “creative ways” to restore critical capabilities just four months after the main phase of the US-Israeli aggression ended in April.
Iran is replenishing its ballistic-missile stockpile and other essential military assets far more rapidly than Israel had thought possible, said the report. It also independently confirms statements by senior Iranian officials that the Islamic Republic is once again manufacturing new weapons at a much higher rate than anticipated.
Western and Israeli media have long put forward unfounded speculations about Iran's arsenal as some claimed Iran retained roughly 500 or 1,000 long-range missiles capable of striking Israeli-occupied territories after this year’s war. That question mattered while Israel and its Western backers assumed Tehran would be limited for years to whatever arsenal survived.
However, the new information changes the picture entirely. With Iran now able to rebuild ballistic missiles at speed, the exact number remaining after the war is far less important than the pace of reconstruction, adds the report.
If production returns to 100–300 missiles per month, Iran could restore its arsenal to June 2025 levels by early to mid-2027 and potentially pose a prohibitive threat to the United States and Israel by 2028, the newspaper wrote.
Even at a more moderate rate, steady progress means the Iranian ballistic-missile "threat" could return in force within just a couple of years, it added.
This is not the first time Israel has been caught off guard. The Israeli military was already surprised by Iran’s rapid recovery in this area twice before, in October 2024 and January 2025.
The latest report arrives as numerous foreign media outlets have already poked holes in Israel’s narrative that its strikes set Iran’s military-industrial complex back by years, a claim circulating since March.
Some Israeli officials now appear ready to look the other way on the ballistic-missile issue, noting that US President Donald Trump has made clear he does not prioritize it.
The New York Times previously reported that Iran successfully used bulldozers to reopen covered underground missile facilities far faster than Israel expected. These efforts restored access to weapons that were never destroyed, only temporarily blocked.
The United States and the Israeli regime launched their illegal war of aggression against Iran on February 28. Yet only forty days later, on April 8, the aggressors were forced to accept a ceasefire in the face of Iran’s determined resistance and highly effective retaliatory operations.
Observers note that Iran’s impressive performance in defending itself and striking back has earned the Islamic Republic widespread international respect.
