TEHRAN (Tasnim) The missiles launched by Iran appear to have directly hit five Israeli military facilities during the recent 12-day war, according to radar data seen by The Telegraph.

The strikes have not been made public by the Israeli authorities and cannot be reported from within the regime because of strict military censorship laws.

The new data were shared with The Telegraph by US academics at Oregon State University, who specialize in using satellite radar data to detect bomb damage in war zones.

It suggests five previously unreported military facilities were hit by six Iranian missiles in the north, south and center of the occupied territories, including a major air base, an intelligence gathering center and a logistics base.

Approached by The Telegraph on Friday, the Israel Defense Forces (IDF) said it would not comment on missile interception rates or damage to its bases.

What we can say is that all relevant units maintained functional continuity throughout the operation, said a spokesman.

The strikes on the military facilities are in addition to 36 others known to have pierced Israeli air-defense systems, causing significant damage to residential and industrial infrastructure.

According to the report, the Iranian missile strikes against the Israeli targets included:

- Seven hits on oil and power facilities

- The destruction of part of the Weizmann Institute, one of Israels leading scientific research centers

- Major damage to the Soroka University Medical Center, a hospital that sits adjacent to a campus of Ben-Gurion University in Beer Sheva

- Strikes on seven densely built residential areas that have left more than 15,000 Israelis homeless

Analysis by The Telegraph suggests that while the vast majority of Iranian missiles were intercepted, the proportion that got through grew steadily in the first eight days of the 12-day war.

The reasons for this, say experts, are not clear but may include the rationing of a limited stock of interceptor missiles on the Israeli side and improved firing tactics and the possible use of more sophisticated missiles by Iran.

Although the Iron Dome is Israels best-known air-defense system, it is actually designed to protect against short-range projectiles such as mortars and is only one part of the layered air-defense system the Zionist regime uses.

In the middle tier stands the Davids Sling air-defense system, which is optimized for intercepting drones and missiles with ranges up to 300km. At the top is the Arrow system, which engages long-range ballistic missiles before they re-enter the atmosphere.

Importantly, the Israeli systems were backed up throughout the 12-day war by two US ground-based THAAD missile-defense systems and ship-based interceptors launched from US assets in the Red Sea.

The US is estimated to have launched at least 36 THAAD interceptors during the war at a cost of some $12 million a time.

In the occupied territories, the piercing of Israels famed missile-defense systems has come as a shock, with the authorities having to issue notices warning that they were not hermetic.

The 15,000 made homeless are especially conspicuous as they have been distributed to hotel accommodation throughout the occupied territories and the restriction of residential sites has been reported freely.

But there has also been growing suspicion within Israel that military targets were hit.

Raviv Drucker of Channel 13, one of the best-known journalists, said last week, There were a lot of [Iranian] missile hits in IDF bases, in strategic sites that we still dont report about to this day... It created a situation where people dont realize how precise the Iranians were and how much damage they caused in many places.

Corey Scher, a researcher at Oregon State University, said his unit was working on a fuller assessment of missile damage in both Israel and Iran, and would publish its findings in around two weeks.

He said the radar system data that they used to assess damage measured changes in the built environment to detect blasts and that absolute confirmation of hits would necessitate either on-the-ground reporting at the military sites concerned or satellite pictures.

The Telegraphs data analysis shows the combined US and Israeli defense systems performed well overall, but were letting through around 16 percent of missiles by day seven of the war.

This broadly accords with an earlier IDF estimate for the defense system that put the success rate at 87 per cent.

Iranian officials say that the main way the Israeli regimes air defenses were pierced was by using missiles and drones at the same time to confuse defense systems.

Fast missiles mixed with slower drones confused the defenses and made them split their attention, officials said.

The main goal of firing [suicide drones] at Israel is always to keep their systems busy, one Iranian official told The Telegraph. Many dont even get through theyre intercepted but they still cause confusion.
