Overview
- Russian Telegram channel Fighterbomber published cockpit footage on August 27 showing the Poseidon with its AN/APS-154 Advanced Airborne Sensor deployed in flight.
- Civil MLAT tracking the same day documented a roughly four-hour Black Sea sortie on a Varna–Sochi track that stayed more than 50 nautical miles from Russian airspace and returned to Naval Air Station Sigonella.
- The intercept involved a Flanker-series fighter, consistent with routine encounters in the area off Crimea reported in recent years.
- The Raytheon-built AAS is a double-sided AESA radar with near-360-degree coverage and modes such as SAR, GMTI and maritime moving target indication, a system seldom seen so clearly in public.
- Reporting notes the sensor can share targeting-quality data with allied forces and, according to some analysts, may infer submarine activity from surface disturbances.
