Israeli air force patrolling approach routes from Iran to head off attacks
At this moment, the Israeli air force is actively trying to hunt down Iranian mobile launchers, mobile sites, and missile storage facilities to try and degrade and destroy Iran’s defensive capabilities, its ability to wage war against Israel.
There will be certain weapons that Iran can use; long-range cruise missiles, which can be fired quickly and travel under radar cover.
This is one of the reasons why the Israeli air force has held quite a lot of its aircraft back because what they are doing is patrolling likely approach routes into Israel in an attempt to try and shoot down any low range drones or low wage cruise missiles, as well as solid fuel missiles that can be launched very quickly for mobile launchers.
The thing is, the Israeli air force is based a long way from Iran. It’s 1,000km (621 miles) before they would even get to the border, so that the Israeli aircraft will have a limited loitering time over Iran.
