A classified CIA technology called "Ghost Murmur", never before used in the field, located a wounded American weapons systems officer hiding in a mountain crevice in southern Iran after his F-15 jet was shot down late last week, the New York Post reported in an exclusive.
The airman, known publicly only by his call sign "Dude 44 Bravo," survived two days in desolate terrain while enemy forces searched the area. The CIA pinpointed his position from roughly 40 miles away, President Trump told reporters at a White House briefing Monday afternoon.
Ghost Murmur uses long-range quantum magnetometry to detect the electromagnetic fingerprint of a human heartbeat, then pairs that data with artificial intelligence software to isolate the signal from background noise. Two sources briefed on the program told the Post that Lockheed Martin's Skunk Works, the defense giant's advanced development division, built the system. Lockheed Martin declined to comment.
The concept sounds like science fiction, but the underlying physics is straightforward. Every beating heart generates a faint electromagnetic pulse. Normally that signal is so weak it can only be measured in a hospital with sensors pressed against the chest.
Advances in quantum magnetometry, specifically sensors built around microscopic defects in synthetic diamonds, have apparently made it possible to detect those signals at far greater distances, a second source with knowledge of Lockheed Martin intelligence collection tools told the Post.
A source briefed on the program described the challenge in vivid terms:
"It's like hearing a voice in a stadium, except the stadium is a thousand square miles of desert."
The same source added a line that doubles as the technology's unofficial motto:
"In the right conditions, if your heart is beating, we will find you."
The name itself carries clinical precision. A source briefed on the program explained that "'Murmur' is a clinical term for a heart rhythm. 'Ghost' refers to finding someone who, for all practical purposes, has disappeared."
The southern Iranian desert offered near-ideal conditions. The source described the environment as "about as clean an environment as you could ask for", "almost no competing human signatures, and at night the thermal contrast between a living body and the desert floor" provided operators "a secondary confirmation layer."
CIA Director John Ratcliffe hinted at the breakthrough during the Monday briefing but took no reporter questions. He said the agency had accomplished its mission by Saturday morning, days before the public knew details of the rescue.
Ratcliffe stated that the CIA had "achieved our primary objective by finding and providing confirmation that one of America's best and bravest was alive and concealed in a mountain crevice, still invisible to the enemy, but not to the CIA."
He added that the confirmation "was relayed by Secretary [of War Pete] Hegseth to the president, and the operation quickly moved to the execution phase." The rescue mission involved hundreds of U.S. troops. Two rescue planes got stuck in a field during the operation, forcing commanders to call in additional aircraft and destroy the stranded jets. Despite those complications, there were no American casualties.
The intelligence community has faced intense scrutiny in recent years, from federal prosecutors targeting former CIA Director Brennan over Russia-probe evidence to broader questions about whether the nation's spy agencies serve the country or their own institutional interests. Ghost Murmur's operational debut represents the opposite end of that ledger: a concrete, life-saving result delivered under extreme pressure.
President Trump was characteristically direct in praising the operation. He told reporters the CIA spotted the missing American from "40 miles away" and called the effort remarkable.
"It's like finding a needle in a haystack, finding this pilot, and the CIA was unbelievable. The CIA was very responsible for finding this little speck."
Trump also acknowledged Ratcliffe's personal role, saying the CIA director "did a phenomenal job that night, he did something that I don't know if you want to talk about it. If you want, you can. I'm not sure he's supposed to."
Then came the lighter moment. Trump suggested the details "might be classified, in which case I'd have to put him in jail if he talks about it and I don't want to put him in jail. He doesn't deserve that." The exchange drew attention to just how closely held the Ghost Murmur program had been, and how reluctant officials remain to discuss its full capabilities.
That caution extends well beyond the White House. National security leadership across multiple agencies has faced turbulence in recent months, including the FBI probe into former counterterrorism director Joe Kent, which predated his resignation and raised questions about oversight of senior officials during wartime operations.
The Post reported that Dude 44 Bravo had activated a Boeing-made Combat Survivor Evader Locator beacon, the standard-issue distress device carried by American aircrews. But the beacon had a critical limitation in this scenario.
A source briefed on the program explained that the airman "had to come out [of the crevice] to send the beacon." The source added: "It was less important the signal they sent and more important that he had to come out to send [it]." In other words, every time the wounded officer exposed himself to transmit his location the conventional way, he also exposed himself to the enemy.
Ghost Murmur solved that problem. It found him while he stayed hidden.
The source said this is "basically why everyone's been so cagey about how [the airman] was actually found," adding: "I don't think people even know this technology is possible from this distance."
The technology had previously been tested on Black Hawk helicopters for future potential use on F-35 fighter jets, the second source with knowledge of Lockheed Martin tools said. But it had never been deployed operationally by the CIA until this rescue.
Ghost Murmur is not a magic wand. The second source cautioned that "the capability is not omniscient. It works best in remote, low-clutter environments and requires significant processing time." How long that processing took during the Iran rescue remains unclear even to the Post's sources.
Whether the system has additional wartime applications, offensive or otherwise, is also unknown. What is clear is that in the specific conditions of a vast, sparsely populated desert at night, the technology performed exactly as designed.
The broader intelligence apparatus continues to navigate questions about accountability and leadership. Reports that Director of National Intelligence Tulsi Gabbard was kept in the dark about the FBI's probe into Joe Kent before his resignation have fueled concerns about internal transparency. Yet the Ghost Murmur deployment suggests that when the mission is clear, find an American and bring him home, the machinery can still deliver.
The Post noted that Ghost Murmur's debut follows another recent disclosure of classified technology. Trump told the Post in January that he deployed a weapon called "The Discombobulator" during the Jan. 3 raid that captured Venezuelan dictator Nicolas Maduro to face U.S. drug and weapons charges. The pattern suggests an administration willing to reveal, at least partially, the tools it uses when the results speak for themselves.
Several questions remain open. The full identity of Dude 44 Bravo has not been released. The exact date of the shootdown and the precise location in southern Iran are still classified or unreported. The enemy force or Iranian unit searching for the airman has not been publicly identified.
Trump's claim that the CIA detected the airman from "40 miles away" has not been independently verified, and it remains unclear whether that figure refers to initial detection distance, a subsequent observation, or something else entirely.
Meanwhile, Washington's political class continues its familiar pattern of infighting over intelligence oversight and executive power. Some Democrats have already signaled interest in new confrontations, Rep. Robert Garcia has floated impeaching Attorney General Pam Bondi if Democrats retake the House, even as operations like this one demonstrate the real-world stakes of a functional national security apparatus.
The technology worked. The airman came home. No Americans died in the rescue. Those are facts, not talking points. And they are worth more than a hundred congressional press conferences.
