The KW-37, code named JASON, was an encryption system developed In the 1950s by the U.S. National Security Agency to protect fleet broadcasts of the U.S. Navy. Naval doctrine calls for warships at sea to maintain radio silence to the maximum extent possible to prevent ships from being located by potential adversaries using radio direction finding.

Full duplex key generator for encryption of digital data. With various converter equipment handles digital voice, facsimile, computer data, and multichannel teletype. Consists of drawer assemblies from KG-3 and KG-12 equipments.

The second generation KW-37 automated monitoring of the fleet broadcast by connecting in line between the radio receiver and a teleprinter. It, in turn, was replaced by the more compact and reliable third generation KW-46.

The sole purpose of the KWR-37 was to automatically decipher the encoded fleet broadcasts which was sent to military ships at sea and other applications where it was required to decode a steady stream of classified traffic. On the input side, the '37 was connected to the 60 milliamp current loop output of a frequency shift converter.
