The F-15EX could be used in the first wave of an attack, obliterating the Islamic Republic’s air-defense systems, including those on the ground and any fighters sent up by the Iranian air force to stop the assault.The second wave could then consist of the three squadrons of F-35 Stealth fighters, equipped with bunker-busting bombs to reach the nuclear facilities hidden deep within mountains or underground.Last June, the Israeli air force conducted a drill simulating an F-35I strike on Iran without the need for mid-air refueling. It also practiced cooperation between the stealth fighters and the older model F-15s and F-16s, which these more advanced jets would replace in due course.Less than two months ago, the IDF held a series of exercises with the U.S. Air Force off of Israel’s coast, practicing a joint strike.“The Intelligence Directorate conducted an extensive simulation that replicated a campaign against distant countries,” the IDF stated at the time.“These exercises are a key component of the two militaries’ increasing strategic cooperation in response to shared concerns in the Middle East, particularly those posed by Iran,” the army added.Read WATCH: Israeli jets return from Operation 'Days of Atonement'The IDF has wanted to order the jet for a long time but was delayed by the inability of Israel to form – and keep – a government for very long, with five elections in the last four years, or to pass a budget that would include such an expenditure. The planes cost roughly $85 million apiece.It is unclear why last year’s unity government was unable to place the order, as it even passed a two-year rather than the more traditional one-year budget.
