The KW-26 (the larger unit on the bottom) encrypted and decrypted teletype messages between large sites in bulk and at fast rates. Widely used with more than 14,000 units produced, the KW-26 superseded the crypto machines of World War II by using electronic shift registers instead of mechanical rotors.

The TSEC/KW-26, code named ROMULUS, was an encryption system used by the U.S. Government and, later, by NATO countries. It was developed in the 1950s by the National Security Agency (NSA) to secure fixed teleprinter circuits that operated 24 hours a day.

The KW-26 ROMULUS was a second generation cipher device in wide use that could be inserted into teletypewriter circuits so traffic was encrypted and decrypted automatically. It used electronic shift registers instead of rotors and became very popular (for a COMSEC device of its era), with over 14,000 units produced.

The KW-26 was used by U.S. /NATO intelligence services to provide point-to-point 100 wpm circuits for expeditious transmission of highly compartmented information. Only the keying material differed from that issued to operational units. Each circuit had a scheduled re-key time every 24 hours called BRAVO INDIA (BI), a process specific to the KW-26.

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 introduction of the KW-26 date back to 1907 with the introduction of the Start/Stop method of synchronizing printing telegraph equipment by Charles L. Krumm and his

A KW-26 system (transmitter or receiver) contained over 800 cores and approximately 50 vacuum-tube driver circuits, occupying slightly more than one half of a standard 19-inch rack. Most of the space in the rack and most of the 1 kW input power were required for the special-purpose vacuum tube circuits needed to provide compatibility with ...
