Heading to Hormuz: Destroyer USS Michael Murphy Breaks Radar Silence

Less than an hour ago, major commercial ship-tracking portals (VesselFinder and MarineTraffic) picked up the AIS signal of the American guided-missile destroyer USS Michael Murphy (DDG-112). The Arleigh Burke-class ship is currently sailing in the waters of the Persian Gulf, heading toward the critical choke point of the Strait of Hormuz.

The vessel’s kinematics show a steady pace: the ship is proceeding at a speed of approximately 20 knots, a transit speed that suggests a rapid movement toward its next area of operations.

The Return After 43 Days of Silence

The most interesting aspect of this detection is the time elapsed since its last known signal. The ship’s previous ping dated back 43 days ago, when it was moored at the port of Jebel Ali in the United Arab Emirates.

It is standard practice for US Navy vessels to operate under EMCON (Emission Control) conditions, turning off public AIS transponders for operational security, especially in high-tension areas like the Middle East. Reactivating the signal while approaching the Strait of Hormuz could be in compliance with strict navigation safety regulations in an extremely congested waterway, or it might represent a deliberate signaling of “presence.”

The Strategic Context and Our Caveat

This tracking holds particular significance: if the track proves correct, it would be the first military unit we have tracked transiting the Strait of Hormuz since the start of the truce.

However, in OSINT analysis, maintaining the usual cautionary caveat is mandatory. In complex operational theaters, AIS anomalies are commonplace. Spoofing phenomena (falsifying GPS/AIS coordinates) or ghost tracks cannot be entirely ruled out.

We will continue to monitor the track to see if the DDG-112 crosses the strait, heading into the Gulf of Oman and the Arabian Sea, or if it alters its navigation pattern.
