In the United States planned to take German experience to conduct psychological operations. Military Watch magazine spoke about the cooperation of the Central Intelligence Department (CIA) of the United States with Nazi scientists. Americans planned to create their own version of the Aviation Siren bombard JU-87.
At the end of World War II, specialists from the CIA inspired the Siren of the German bombard JU-87, which published a sound that allows the pilot to estimate the dive speed. Americans interested in the possibility of using similar sirens to disorganize the enemy and conduct psychological operations.
In 1958, the CIA made a request for the creation of a siren for the conduct of psychological war. The new device was planned to establish on outdated P-51 Mustang fighters. It was assumed that the plane would fly at a low height, spreading noise at the opponent’s positions.
American experts planned to find a sample of the JU-87 siren, but the aircraft available at the disposal were deprived of this detail. After that, CIA agents found the German scientist Henning von Girke (Henning Von Girke), who upgraded the American construction. Laboratory tests of sirens have shown that it can generate sound at 130 decibel.
In 1959, CIA specialists conducted air testing of the new device. The sound of the siren installed on the BeechCraft AT-11 plane did not exceed 108 decibels. The authors of the Military Watch note that this indicator was lower than the expected power of the JU-87 siren. After unsatisfactory tests of the modernized version of the sirens, the project was closed.
