US bombing of Iran started with a fake-out
WASHINGTON, June 22 (Reuters) – As Operation “Midnight Hammer” got underway on Saturday, a group of B-2 bombers took off from their base in Missouri and were noticed heading out toward the Pacific island of Guam, in what experts saw as possible pre-positioning for any U.S. decision to strike Iran.
But they were a decoy. The real group of seven bat-winged, B-2 stealth bombers flew east undetected for 18 hours, keeping communications to a minimum, refueling in mid-air, the U.S. military revealed on Sunday.
As the bombers neared Iranian airspace, a U.S. submarine launched more than two dozen Tomahawk land attack cruise missiles. U.S. fighter jets flew as decoys in front of the bombers to sweep for any Iranian fighter jets and missiles.
The attack on Iran’s three main nuclear sites was the largest operational strike ever by B-2 stealth bombers, and the second-longest B-2 operation ever flown, surpassed only by those following the September 11, 2001, attacks on the United States by al Qaeda.
The B-2 bombers dropped 14 bunker-busting GBU-57 Massive Ordnance Penetrators, each weighing 30,000 pounds. The operation involved over 125 U.S. military aircraft, according to the Pentagon.
From the U.S. military’s perspective, the operation was a resounding tactical success. The Iranians were unable to get off a single round at the American aircraft and were caught completely flat-footed, General Dan Caine, the chairman of the Joint Chiefs of Staff, told reporters at the Pentagon on Sunday.
“Iran’s fighters did not fly, and it appears that Iran’s surface to air missile systems did not see us throughout the mission,” Caine said. “We retained the element of surprise.”
Caine said initial battle damage assessments indicated that all three sites targeted sustained extremely severe damage and destruction, but he declined to speculate whether any Iranian nuclear capabilities might still be intact.
U.S. Defense Secretary Pete Hegseth was more confident.

“It was clear we devastated the Iranian nuclear program,” he said, standing alongside Caine in the Pentagon briefing room.
Midnight Hammer was highly classified, Caine said, “with very few people in Washington knowing the timing or nature of the plan.” Many senior officials in the United States only learned of it on Saturday night from President Donald Trump’s first post on social media.
Hegseth said it took months of preparations to ensure the U.S. military would be ready if Trump ordered the strikes. Caine said the mission itself, however, came together in just a matter of weeks.
What happens next is unclear.
Gulf states, home to multiple U.S. military bases, were on high alert on Sunday as they weighed the risks of a widening conflict in the region.
Guarding against blowback, the U.S. military also dispersed U.S. military assets in the Middle East and heightened force protection for U.S. troops.
Hegseth said the U.S. military was positioned to defend itself in the Middle East, but also to respond against Iran if it goes through with longstanding threats to retaliate.

The Trump administration said it is not looking for a wider war with Iran, with Hegseth saying private messages had been sent to Tehran encouraging them to negotiate.
But Trump has also warned Iran that the U.S. is prepared to hit additional targets if needed, using far greater force.
“Iran would be smart to heed those words. He said it before, and he means it,” Hegseth said.
