[0392-2222] THE WALKER RING – Companion Dossier (PDF)

Description

On a freezing November night in 1985, an FBI counterintelligence team watched Chief Warrant Officer John Anthony Walker Jr. toss a black trash bag near an unmarked basalt boulder in rural Maryland. Inside that bag lay sixty pounds of classified material: cryptographic keylists for the KW-7 and KG-14 ciphers, nuclear submarine routing orders, and hand-scrawled operational notes to his Soviet handler. For seventeen years, Walker had operated an unprecedented family espionage enterprise, feeding the KGB over one million encrypted naval transmissions and allowing Moscow to track US ballistic missile submarines in near-real time. This declassified investigative dossier presents a forensic dissection of the operation known within the bureau as ‘Windfall.’ Complete with reconstructed dead-drop timelines, technical analyses of compromised rotor systems, and FBI evidence inventories, this document maps the systemic procedural blindness that allowed an indebted naval custodian to sell the nation’s nuclear deterrent. Trace the tradecraft from Walker’s initial walk-in on 16th Street NW to the Quantico crime lab tests that exposed the most catastrophic intelligence compromise in modern naval history.
