The Russian unit came under Ukrainian control after the collapse of the Soviet Union in 1991, and almost completely ceased operations. It has been revived since the annexation of Crimea in 2014 and has been restored to operational operation. “Our experts have developed new devices that turn the underwater detection of dolphin sonar targets into a signal to the pilot’s screen,” a source told Russia’s RIA Novosti news agency. “The Ukrainian navy did not have the funds for such know-how and some projects had to be imposed.” The United States has also used dolphins and sea lions, which are also trainable during the Cold War, to spend at least $ 28 million.
