A Russian signals-intelligence vessel — the Kareliya (SSV-535) — has been detected operating just off U.S. territory near Hawaii. Satellite passes, ship-tracking data, and OSINT monitoring all show the Kareliya moving slowly through the Pacific in a pattern that typically aligns with U.S. missile test activity.Russia rarely deploys its intelligence ships this far from home. When they appear near Hawaii, it usually signals interest in America’s missile defense network, radar testing, and long-range strike systems based in the region. These vessels act as floating electronic listening posts, collecting radar signatures, telemetry, and communications to update Russia’s strategic picture.In this OSINT briefing, we break down:• Why a Russian spy ship is operating this close to the U.S.• What the Kareliya actually collects (SIGINT/ELINT)• How satellite imagery confirms its activity• Why Hawaii is central to America’s Pacific command-and-control• How Russia uses these deployments to track U.S. missile testingThis analysis is based entirely on open-source intelligence and publicly available data.#OSINT #Navy #Russia #Hawaii #Intelligence #Pacific #Military #Defense #MilitaryAnalysis
