In 1976, Parche was moved to the Pacific fleet and modified for the first time. Not much is publicly known about this initial retrofit, but the submarine's service exploits fell out of the public eye very quickly. As it turns out, the Navy selected Parche to support the National Underwater Reconnaissance Office — a highly secretive joint partnership between the Central Intelligence Agency and the Navy.
Over the next few years, Parche's mission set rapidly evolved from functioning as a typical run-of-the-mill attack submarine, to a ghost-like spy submarine, outfitted with monitoring gear, reconnaissance, and surveillance systems. The submarine force is often known as the "silent service" due to the fact that submarines work best when undetected. NURO and the Navy took this a step further with crews assigned to the Parche, swearing them to absolute secrecy, owing to the nature of their command's job.
By the end of the 1970s, Parche had already made multiple trips into the Sea of Okhotsk, along with the USS Halibut and the USS Seawolf, to wiretap Soviet communications cables as part of Operation Ivy Bells. These wiretaps, undetected until a National Security Agency leak in the mid-80s, proved to be extremely invaluable in picking up Soviet military intelligence. The Parche also assisted with recovering the fragments of Soviet anti-shipping rockets, so that the Navy could analyze them and develop countermeasures to safeguard its own vessels.

Now retired, David LeJeune was a Navy saturation diver who participated in several later missions. Although he was unable to answer many questions, he says that the information that he and his fellow divers uncovered led to the successful completion of the SALT II talks, which was eventually signed in 1979 and restricted each country's nuclear delivery systems.
LeJeune also says the tech and gear they were using was cutting edge. "We were using technology that is so far advanced from the civilian community that the public doesn't know that capability even exists."
Over three decades later, this type of wiretapping is thought to be largely obsolete. Thanks to the digital age, there are far more efficient, easier, and less risky ways to spy on someone's comms. However, these types of underwater cables still exist and are of great importance. As the New York Times reported in 2015, there are continued fears that these cables could be cut, effectively halting communications across the globe.
But, even though this type of surveillance may be old fashioned, Reed thinks it's possibly still happening today. "Submarines absolutely still have the capability to do these kind of missions and there are personnel that are still trained on how to do these missions," says Reed. "Whether or not those missions are still underway, that would be considered classified."
