Israel shot down Iranian missiles with F-35I Adir stealth fighter jets that cost $44,000 per hour to fly

F-35 Lightning II stealth fighter jets produced by Lockheed Martin are some of the most advanced military aircraft in the world.

The F-35 stores its weapons and fuel internally, and its aligned edges and radar-absorbent coating also help the aircraft evade detection. The planes cost $44,000 per hour to fly, The National Interest reported in January.

They feature advanced stealth and information-processing capabilities and can reach supersonic speeds of Mach 1.6, or 548.8 meters per second.

Lockheed Martin CEO Marillyn A. Hewson said in 2018 that the planes "can fly in what we call 'beast mode,' carrying up to 18,000 pounds of internal and external ordnance, in a mix that can include 5,000-pound-class weapons."

In 2016, Israel became the first country other than the US to acquire F-35 fighter jets.

Israel was the first country to select the model through the US Foreign Military Sales process and bought 50 planes, according to Lockheed Martin.

Israel has made significant modifications to the jets.

Israel manufactures its own wings and electronic warfare system for the F-35I. It also developed its own version of the high-tech helmet that displays the plane's airspeed, altitude, targeting information, and other crucial stats directly on the pilot's visor.

The Israeli Air Force named its F-35I variant "Adir," meaning "Mighty One" in Hebrew.

The Israeli Air Force also added a six-pointed Star of David to the design, a Jewish symbol that also appears on the Israeli flag.

In 2018, Israel became the first country to use the F-35I in combat, its air force chief said.

"We are flying the F-35 all over the Middle East and have already attacked twice on two different fronts," then-Israeli Air Force chief Major-General Amikam Norkin said in a speech at a gathering of foreign air force leaders, Reuters reported.

In July 2023, Israel acquired an additional 25 Adir planes in a $3 billion deal.

The deal was financed through the military aid Israel receives from the US, Reuters reported.

In November 2023, Israel's F-35I Adir fighter jets took down a missile fired by an Iran-backed group in Yemen, according to the IDF.

It was the first known intercept of a cruise missile by an F-35 plane.

The Israeli Air Force released footage of the encounter on X, writing in Hebrew that its personnel are "preoccupied at every moment with planning and managing the defense response and are prepared for any threat in any area."

Iran appeared to target the Nevatim air base, which houses Israel's fleet of F-35I jets, during an unprecedented attack on Sunday morning.

Out of the over 350 ballistic missiles, cruise missiles, and UAVs, or unmanned aerial vehicles, launched at Israel by Iran and its proxies in Iraq, Yemen, and Lebanon, around 99% were intercepted by Israel and its allies. The IDF released photos showing minor damage near a runway at the Nevatim Airbase and to a road in Hermon caused by the few projectiles that landed.

The Nevatim base remained operational throughout the attack, according to the IDF, with the Adir fighter jets aiding the defensive mission.

"Iran thought it would be able to paralyze the base and thus damage our air capabilities, but it failed," IDF spokesperson Rear Adm. Daniel Hagari said in a statement.

The ongoing war in Gaza has prompted new scrutiny of US military aid to Israel.

The October 7 terrorist attacks carried out by Hamas killed around 1,200 Israelis and captured over 240. Around 129 hostages remain in Gaza, though it is unknown how many are still alive.

Israel's counteroffensive airstrikes and military actions in Gaza have resulted in over 33,000 Palestinian fatalities, including around 14,500 children, according to figures provided to the United Nations Office for the Coordination of Humanitarian Affairs by the Hamas-run Ministry of Health in Gaza. The IDF reports that 13,000 of these fatalities were Hamas militants.

According to the UNRWA, over 1.7 million Gazans have been displaced and 1.1 million are at risk of "catastrophic levels of food insecurity."

The devastating human toll of the war in Gaza with US-funded planes like the F-35I has prompted new scrutiny of US aid to Israel, with some lawmakers in Congress raising the possibility of conditioning military and economic aid.
