This intelligence vacuum created the impetus for a novel approach.
Identifying the Target
Intelligence analysts, poring over scant clues and monitoring open-source information, began to focus on the Okhotsk Sea, a body of water off the coast of Siberia. This area was suspected of being a primary operating ground for the Soviet Pacific Fleet’s submarines, including ballistic missile submarines (SSBNs) and attack submarines (SSNs). More importantly, it was believed that critical communication cables linking these submarines to Soviet naval headquarters were laid on the seabed within this relatively enclosed sea. These underwater cables were the digital arteries of the Soviet command and control network, carrying invaluable strategic and tactical information.
The Technological Leap
The concept of tapping into an underwater communication cable was not entirely new, but the shallow depths and often turbulent waters of the Okhotsk Sea, combined with the need for complete stealth, presented unprecedented engineering challenges. The operation required advancements in deep-sea diving technology, autonomous underwater vehicles (AUVs), and sophisticated recording and transmission equipment. The technical hurdles were immense, demanding an ambitious and secretive development program within the intelligence community.

The declassified records detail the extensive re-engineering required to transform this conventional warship into a cutting-edge spy tool. The Halibut became a mobile, submerged intelligence hub, a silent hunter of secrets beneath the waves.
The Cable Tapper
The technical marvel at the heart of Ivy Bells was the “pod” – a large, complex device designed to physically straddle the Soviet communication cable. This pod was not designed to cut or splice the cable, which would have instantly triggered alarms. Instead, it inductively coupled with the electrical signals flowing through the cable, passively “listening” to the transmissions without direct metallic contact. The declassified schematics reveal the ingenious circuitry and design that allowed the pod to extract data from multiple communication channels simultaneously, encompassing voice, teletype, and potentially other digital formats. The pod was a passive ear, recording every whisper of the Soviet naval apparatus.
Deployment and Recovery
Each mission involved the Halibut meticulously locating the target cable using advanced sonar and navigation systems. Once identified, a team of highly-trained Navy divers, operating in extremely cold and hazardous conditions, would then deploy from the Halibut’s moon pool. These divers, often using specialized submersibles or diver propulsion vehicles, would locate the cable and attach the listening device. The declassified records highlight the incredible bravery and skill of these individuals, working in a lightless, hostile environment where a single mistake could lead to disaster or exposure. The pod would then record transmissions onto magnetic tapes, which were later retrieved by subsequent missions or remotely transmitted via highly encrypted bursts.
