The Central Intelligence Agency is reported to have used a previously undisclosed technology known as “Ghost Murmur” to locate and assist in the rescue of a US airman downed in Iran, according to media reports that have not been independently verified.
The claim, first reported by the New York Post, suggests that the tool was used to detect the heartbeat of a missing crew member after an F-15E Strike Eagle aircraft was shot down southwest of Isfahan. The incident reportedly triggered a high-risk search and rescue operation involving US military assets.
According to the report, the airman, identified only by the callsign “Dude 44 Bravo,” was serving as a weapons systems officer on board the aircraft. Donald Trump reportedly described him as a “highly respected Colonel,” although further identifying details have not been made public.
The pilot is said to have ejected safely and was recovered shortly after the incident by military helicopters. However, the second crew member reportedly landed approximately 200 miles behind enemy lines, injured and isolated in mountainous terrain, where he evaded capture for more than 36 hours.
Trained in survival, evasion, resistance and escape (SERE) techniques, the airman is believed to have activated a survival beacon manufactured by Boeing before seeking cover. Despite this, his precise location reportedly remained unclear due to the challenging terrain.
Reports suggest that “Ghost Murmur” was then used to narrow down his position, allegedly by detecting physiological signals such as a heartbeat. If accurate, such a capability would represent a significant advancement in battlefield search and rescue technology, particularly in environments where traditional tracking methods are limited.
However, details about the system remain unclear. There has been no official confirmation from CIA or the US Department of Defense regarding the existence or use of any technology by that name. It is also unclear whether the tool is a standalone system or part of a broader suite of surveillance and detection capabilities.
Analysts caution that reports involving classified technology should be treated carefully, particularly when originating from unnamed sources or outlets citing limited information. Similar claims in the past have often mixed verified capabilities with speculative or exaggerated elements.
The rescue operation itself, however, fits within known US military doctrine. The United States maintains extensive personnel recovery capabilities, including rapid-response teams trained to extract isolated personnel from hostile environments. Such missions often rely on a combination of satellite imagery, signals intelligence, and survival beacons.
The reported incident comes amid heightened tensions in the region, where any military engagement carries broader geopolitical implications. A successful recovery of a downed airman in contested territory would likely be seen as both a tactical and symbolic achievement.
At the same time, the emergence of terms like “Ghost Murmur” highlights the persistent gap between publicly acknowledged capabilities and those that remain classified. Whether the technology exists as described or is simply a label used in reporting remains an open question.
For now, much of the information surrounding the incident, including the exact role of the alleged tool, remains unverified.
