Seabed warfare has been brought into sharp focus by Russia’s ongoing efforts to map undersea infrastructure. And by the September 2022 with the attack on the Nord Stream gas pipelines in the Baltic. There is no suggestion that the USS Jimmy Carter was involved in the Nord Stream incident (it wasn’t!). But the attack shows the relevance of these capabilities. Most seabed warfare however is closer to espionage than sabotage. And the American submarines excel.
The history of operations against undersea infrastructure, such as sensor networks, communications and energy infrastructure goes back a long way. And both the U.S. Navy and Russian Navy have strong traditions.
In the 1970s Operation Ivy Bells saw the U.S. Navy tapping Soviet communications networks deep undersea. Tapping the cables which the Soviets thought were safe gave the U.S. valuable insight and intelligence. The first tap, in the Sea of Okhotsk was followed by several others of similar significance but less fame. The USSR only found out about them when a Soviet spy deep in the American intelligence apparatus, Ronald Pelton, betrayed them.
