A U.S. Air Force RQ-4B Global Hawk, callsign FORTE10, returned to Sicily’s Sigonella Air Base after a nearly 24-hour reconnaissance loop over the Black Sea on October 25. The flight restores a persistent high-altitude ISR presence that Washington had restarted in May and sustained through late summer, reinforcing allied visibility of Crimea, occupied eastern Ukraine, and adjacent Russian coastlines.
A renewed Global Hawk patrol over international waters of the Black Sea marked a fresh round of U.S. long-endurance surveillance, according to flight-tracking reports that have monitored FORTE10’s profile since operations resumed in May. The RQ-4B departed and recovered at NAS Sigonella, a familiar hub for HALE missions, with OSINT trackers noting orbits aligned to previous boxes west of Crimea and along Romanian approaches, consistent with the pattern documented in spring and late summer reporting. The move fits the broader return of U.S. HALE coverage after an 11-month pause, complementing manned patrol aircraft and NATO command-and-control assets.Follow Army Recognition on Google News at this link

The RQ-4B is a Northrop Grumman system designed for wide-area persistent sensing. Three technical points define its role. First, endurance exceeds 30 hours, with a record beyond 34 hours, and the operational ceiling reaches 60,000 feet (≈ 18,300 meters), which preserves geometry over large sectors while remaining above defenses. Second, the Block 40 carries the AN/ZPY-2 Multi-Platform Radar Technology Insertion Program (MP-RTIP) active electronically scanned array (AESA) radar, providing synthetic aperture radar (SAR) imagery and ground moving target indication (GMTI). The Block 30 combines electro-optical and infrared imaging with high/low signal intelligence (SIGINT) suites. Third, propulsion relies on a Rolls-Royce AE 3007H turbofan (F137 designation) producing about 7,600 lbf of thrust, shaping persistence and fuel efficiency, supported by a wing of roughly 39.8 meters span and a maximum takeoff weight near 14.6 tonnes. Payload is about 1,360 kg and cruise speed is around 310 knots, with an inter-theater range of roughly 12,300 nautical miles.
The platform combines line-of-sight links and wideband Ku satellite relays to disseminate mission products and receive timely retasking. This backbone matters because the value of ISR is temporal: latency and throughput determine whether a track becomes actionable, a correlation, or a missed opportunity. In a communications-relay configuration, EQ-4 airframes carry the Battlefield Airborne Communications Node (BACN) to bridge data links and tactical voice. Operations rely on a Launch and Recovery Element (LRE) and a Mission Control Element (MCE) consisting of a pilot and a sensor operator. The remote crew covers three functions, and the ground stations handle health monitoring, flight control, and ATC/airborne control coordination.
A patrol like FORTE10 provides persistence without entering national airspace. The pattern remains over international waters while sensors look north and east toward maritime approaches, coastal infrastructure, and the lines sustaining occupied Crimea. Under EMCON constraints, the aircraft delivers time on station and revisit rates that a crewed fleet cannot sustain. P-8A Poseidon aircraft add acoustic and electronic collection to the north, and AWACS maintains the air picture and deconfliction, but none of these platforms replace a HALE asset that can hold the line day and night. The effect is cumulative: repeated passes, change detection, track quality on mobile launchers or logistics convoys, and time-sensitive cues for national and allied collectors. In alert posture, the same persistence links naval movements, ATO rhythms, and ground dispersion patterns to support a more complete operational narrative.
Since 2023, patrol boxes have shifted farther from Crimea to reduce interception risks and manage escalation thresholds. This approach continues: international waters provide a clear legal basis, while sensor ranges and viewing angles retain coverage of corridors from Sevastopol to the Kerch Strait and the northern Black Sea. The United States and NATO have refined deconfliction with civil traffic and regional forces, while tactical data links and standard message formats preserve interoperability. For allied forces on the Romanian and Bulgarian coasts, responsive ISR fills gaps in the maritime operating picture and supports coastal batteries that require quality tracks to engage.
Beyond the sensor-patrol mechanics, the sortie points to the defense industrial and technological base (BITD) on both sides of the Atlantic. Sustaining HALE fleets, exploitation chains, and secure ground segments relies on a network of prime contractors and SMEs. This framework matters as Europe invests in a denser ISR and air policing stack and NATO integrates national feeds into a common core. Operational effect depends as much on analysts, bandwidth, and storage as on the platforms. In brief, availability is a system property.
The return of US HALE patrols over the Black Sea signals an allied intent to maintain transparency over Russian naval and air activity without crossing legal thresholds, while providing Kyiv with a more stable foundation of shareable indicators through established channels. The central role of Türkiye as a littoral power, and the proximity of Romania and Bulgaria keep the basin under steady diplomatic and military observation. Moscow may protest and track the flights, but the legal basis remains firm and the ISR value is difficult to dispute. For Washington and its allies, deterrence in this case rests on knowledge rather than display, anchoring the strategic discussion in observed facts rather than approximation.
