USO stands for Unidentified Submerged Object: a UAP that appears to interact with water or transit between air and sea. Reports like the 2004 Nimitz “Tic Tac,” the 2013 Aguadilla thermal video, and the 1967 Shag Harbour case suggest some UAP approach, skim, plunge, and even re-emerge from the ocean. This feature explores a practical question: if such events are real, where would these craft most likely travel—and why would the ocean be the perfect cover? USO 101: Why the Ocean Makes Sense The sea offers stealth. It absorbs radar and light, muffles sound, and provides a vast, low-traffic volume for maneuvering. In addition, much of the U.S. and NATO sensor grid focuses on air threats, leaving gaps underwater or near the surface. Historic Navy hydrophone networks (e.g., SOSUS/IUSS) don’t cover every coastal shelf, and their data are mostly classified. In short: the ocean is a natural blind spot. Key Cases Often Cited with USO Behavior Nimitz “Tic Tac,” 2004: Carrier pilots described a smooth, wingless object and a “churning” patch of ocean as if something was just beneath the surface. Aguadilla, Puerto Rico, 2013: A DHS thermal video shows a small object flying low over land and water at night, appearing to enter the sea and later split into two. Shag Harbour, Nova Scotia, 1967: Witnesses reported an object descending into the water; divers searched the seabed with no debris found. Southern California training ranges, 2019: Navy ships logged swarms of unknown craft near the Channel Islands—illustrating how crowded air/sea test areas complicate identification. “USO Highways”: Likely Corridors to Watch Based on bathymetry, traffic patterns, and infrastructure, several corridors stand out. These are not proof of UAP—just data-driven zones where unusual activity would be harder to track and easier to mistake for routine traffic. 1) Deep Trenches Adjacent to Coasts Puerto Rico Trench: The Atlantic’s deepest point sits just north of the island—close to the Aguadilla case and near busy air/sea lanes. Monterey Submarine Canyon (CA): A deep canyon near dense test ranges and shipping, with frequent marine layer and night haze that degrade visuals. Tonga, Philippine, and Kuril-Kamchatka Trenches: Extremely deep Pacific corridors with sparse surface traffic across long stretches. 2) Undersea Cable & Sensor Chokepoints Global internet cables converge at coastal “landing stations.” These zones host survey ships, ROVs, and maintenance activity, creating noise and clutter that could mask anomalies. They’re also strategically vital, so unusual activity draws attention—but not always public reporting. Hot hubs: Guam & Hawaii; U.S. East Coast (Virginia Beach, Florida); Mediterranean hubs (Sicily–Marseille); UK/Western Europe (Cornwall, Brittany); and East/Southeast Asia clusters. 3) Military Ranges & Instrumented Sea Lanes Areas with lots of sensors also have lots of decoys: drones, balloons, training targets, flares, and classified tests. That mix can both reveal anomalies and confuse analysis. Southern California, Virginia Capes, and parts of the Western Pacific are prime examples. Could Our Sensors Be Missing Transmedium Events? Night-vision systems, compressed phone video, and mis-focused optics can turn point lights into “triangles” or make reflections look like objects. Meanwhile, underwater, hydrophone lines and seabed arrays may not cover near-shore shelves or small bays. NASA’s 2023 UAP study and the DoD’s AARO both stress a core problem: our data are inconsistent, often uncalibrated, and rarely synchronized across air/sea sensors. Until that changes, uncertainty persists. What Would Prove a USO? Multi-sensor capture: Synchronized video + radar + IR + acoustic + AIS/ship track data for the same time window. Two-angle visual: Independent cameras with landmarks and compass bearing. Water interaction: Visible wake, splash crown, cavitation trail, or thermal plume consistent across sensors. Raw files & metadata: Original EXIF, GPS, and time sources preserved and shared. Reader Call-Out: Coastal Watch Live near the coast or work at sea? If you film a suspected USO, capture a steady 10–30 seconds with landmarks, then pan to horizon, Moon/stars, or ships for scale. Log time, GPS, bearing, wind, tide, and note any ship, drone, or flare activity. If safe, check AIS/FlightRadar after. Send reports (with raw files) to your local MUFON/SCU chapter and tip us at Anomalien. Bottom Line Most “USO” buzz fades under scrutiny—drones, balloons, birds, reflections, or routine military activity explain many cases. Yet a few incidents showing clear water interaction remain unresolved. If UAP do exploit the ocean, the smart places to look are deep coastal canyons, cable landing zones, and busy range corridors. With better multi-sensor data, we can finally separate myth from mechanics.
