Introduction
Submarine communications technology has not advanced much since the Cold War. Before then, not only were submarines run by diesel, but they could only communicate with their base when they surfaced and used a radio link. It was impossible for them to communicate with the base station underwater. This was probably due to the fact that radio waves dissipate quickly through water.
After submarines had advanced to use nuclear reactors and could stay underwater for months at a time, developing a method to communicate with the submarine while it was submerged was a necessity. The advancement in submarine communications was also due to the vulnerability of surfaced submarines.
Today, there are two major ways to talk to submarines while they are submerged, the underwater telephone and low frequency radio. Research is also being done to improve transmissions through the study of neutrinos.
