Here we see a great and very rare, maybe even unique picture of former US president Ronald Reagan using a STU-II secure telephone:

In this picture we see president Reagan making a phone call to his staff regarding the invasion of Grenada. Because he was staying at the Eisenhower cabin on the Augusta National Golf course in Georgia, it was necessary to create a secure telephone line with the White House.

This was done by installing a STU-II, which was the second generation Secure Telephone Unit (STU). This system was introduced by the NSA in the early 1980s, and replaced older systems, like the extremely bulky KY-3, and was the successor to the STU-I.

In the picture we see the STU-II telephone, with handset, a normal keypad, some indicator LEDs and three extra buttons at the bottom, for selecting secure or nonsecure mode. This phone only acted as terminal or user interface, because the actual encryption system (crypto designation: KY-71) was located in a large metal cabinet, with which it was connected through a thick 9-way cable. The STU-II was built by ITT with Northern Telecom as a sub-contractor.

Additionally, a reader of this weblog told us that during presidential roadtrips the STU-II was transported in aluminium transit cases with a packed weight of 170 lbs. Each case contained one KY-71 (the crypto engine), one HYX (the handset) and two ZAMX (unknown).


As of 1987, the STU-II was replaced by the much smaller STU-III, which was a secure phone that consisted of one single desktop device only and had much better speech quality. This new phone became available for president Reagan by the end of his second term:
