How damaging was Hezbollah's rocket barrage on Israeli air base?

The Israeli military said Sunday night it was investigating damage at the Meron air force base caused by missile fire from Lebanese territory. 

Hezbollah fired more than 40 rockets and several missiles at Mount Meron, which is just five kilometers (three miles) from the Lebanese border. Israel’s public broadcaster Kan reported that because the anti-tank missiles were fired straight forward, the Iron Dome anti-missile defense system failed to intercept them. The Israel Defense Forces said that the base’s air traffic control center was damaged, though it didn’t provide details on the extent or explain why the attack was not thwarted by Israel’s missile defense system.

IDF spokesperson Daniel Hagari said Sunday night that the damage to the base was being repaired and that the hit did not stop the systems at the base from operating. “Thanks to preparations in advance, the unit continues to function and has other systems as backup,” he said.
