Six days into the war between the United States, Israel and Iran, bombardments are intensifying – as are questions about how long the conflict can last, whether air defence systems can keep up and

President Trump’s war is the latest campaign that has drained missile stockpiles and stretched American forces thin.

Iran has destroyed a key $300 million radar system crucial to directing US missile defense batteries in the Gulf that risks further straining the region’s ability to counter future attacks, according to a US official.

Defense Secretary Pete Hegseth says the U.S. is quickly gaining air superiority over Iran but the U.S. can't stop all air attacks.

What remains of Iran’s ability to fight in the air, and how much of that fight must be conducted solely with drones rather than manned fighters and helicopters?

Israel and the US made going after Iran's defenses and launch sites a priority, while also leaning on air defenses to fight against attacks.

Iran’s air force was the most powerful in the Middle East in 1979, and nothing about it has changed since then. That’s a big problem for Tehran.

Iranian President Masoud Pezeshkian said the country would cease its attacks on neighboring nations unless it was hit first. He also dismissed President Donald Trump's call for an "unconditional surrender” as Operation Epic Fury continues.

The U.S. says it has hit more than 3,000 Iranian targets in the first week of the war, as Iran's president vows to halt attacks on neighbors.
