CAPT Joseph B. Harrison III, USN, was honored in Tampa, FL and retired after nearly 40 years of naval service to our beloved nation in a ceremony that was held on June 25, 2026.
SIGINT Data Processing and Exploitation
Just as solid-state electronic technology changed the capabilities of SIGINT satellites dramatically, the computer revolution that began in the 1950s, and that is still underway, changed the capabilities of computer processing, almost day to day. The capability to process SIGINT information was especially powerful and quick to develop, because the SIGINT satellites collected electrical signals that, with proper coding, were in a form that computers could work on directly. From 1960 to 1975 the multiplying effect of improved satellite collectors and improved computer processors would provide a many-fold increase in operational capabilities. Developing the processing methodology was the key.

The Navy’s center of gravity is evolving toward the information domain—not because it replaces ships or aircraft, but because it has become the decisive enabler of lethality, survivability, and decision advantage at sea.

Imaging and Signals Intelligence Space Systems
The major effort within the US satellite reconnaissance program in the 1960s and 1970s featured overhead visual imaging systems, which produced information not obtainable any other way. (CORONA, GAMBIT, and HEXAGON, the early filmbased satellite systems, have already been well documented.) But there were important intelligence questions that could not be answered with pictures alone. The first question involved determining the location and characteristics of Soviet radars that could detect American strategic bombers. The second involved the performance capabilities of Soviet missiles—ICBMs and ABM systems. These two problems led the list of reasons favoring SIGINT satellites that could listen to and record the signals of Soviet radars, radio communications, and telemetry systems.

Mission Requirements
Considering the prospect of a nuclear war with the Soviet Union, United States leaders in the 1950s had to know two things. First, what were the Soviets doing in their strategic missile programs? They had already demonstrated a nuclear capability with an atomic detonation in 1949 and a fusion-weapon test in 1953. Could they launch a nuclear weapon on a rocket over intercontinental distances? Second, how effective might Soviet defenses prove to be against US forces? Could the Soviets detect and shoot down US long-range bombers? And could the Soviets counter the developing US missile capability?

Chief Towner entered the U.S. Navy Delayed Entry Program during his junior year of high school and subsequently enlisted on 18 June 1984 following graduation from Flagler Palm Coast High School in Palm Coast, Florida. Following recruit Training at RTC Orlando, Florida he reported to Naval Technical Training Center Corry Station Pensacola, Florida, for CTR/T A-school.
