Jerry O. Tuttle

Tuttle led development of the Navy's Joint Operational Tactical System (JOTS) Command and Control System. “JOTS began as a prototyping effort that was first deployed aboard ship in the early 1980s. This system provided the operational commander with the first integrated display of data for decision support purposes. System functionality eventually included track management, track analysis, environment prediction, and a variety of tactical overlays and Tactical Decision Aids (TDAs). JOTS was capable of receiving various data and message input such as Link 11, Link 14, Tactical Data Information Exchange System-A (TADIXS A), Officer in Tactical Command Information Exchange System (OTCIXS), High Interest Track (HIT) Broadcasts, and U.S. Message Text Format (USMTF) messages. JOTS allowed the Fleet Command Centers to interface with command ships and other shore installations. Through the use of a tactical data base manager (TDBM), JOTS provided a consistent tactical battlespace picture for all supporting warfare commanders afloat and ashore.” ^[6] It was joked that JOTS really stood for the “Jerry O Tuttle's System.”^[7] After the first 18 months of Carrier Group Eight's efforts, when finally formalized and using the Joint Naming protocols of the time, “Joint Operational Tactical System” was adopted as a more acceptable alternative.^[8]

Tuttle also spearheaded DOD and NATO adoption of “over-the-air rekeying” (OTAR) for communications encryption/decryption keys.^[9] This innovation, originated by the Navy European Command, permitted code keys to be securely distributed via electronic communications channels, thereby virtually eliminating necessity of production and distribution of thousands of physical keys. This obviated astronomical logistical and security costs while also closing vast communications espionage vulnerabilities thought, until that time, to be inherently unavoidable.

Tuttle died on October 30, 2018, in Fairfax, Virginia.^[10] He was buried at Arlington National Cemetery.^[11]
