Honoring CAPT Michael S. Salehi, USN

Some careers are shaped by careful planning. Others are shaped by history.

For CAPT Michael S. Salehi, the defining chapter of his Navy career began aboard USS Philippine Sea (CG 58). Just months before the attacks of September 11, 2001, he served as the ship’s Visit, Board, Search and Seizure (VBSS) Officer, leading boarding team operations during deployment in support of maritime security missions. On September 11, he was deployed with Philippine Sea as the United States came under attack. Just weeks later, the ship became the first to launch Tomahawk cruise missiles into Afghanistan during Operation Enduring Freedom. Like so many who served during that generation, the attacks reshaped not only the nation’s priorities, but the course of his own career.

Early History of the National Reconnaissance Office (5 of 5)

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.
