NSA mourns the loss of former Director Lt Gen Kenneth Minihan

In autumn 2019 — two decades after he established the Cryptologic Hall of Honor as a way to pay special tribute to American cryptology pioneers and heroes — former NSA/CSS Director Lt Gen Kenneth A. Minihan returned to the Agency for his own induction.

The creation of the hall serves as one of the defining achievements of Lt Gen Minihan’s time leading NSA from 1996 to 1999.

Earlier this month he passed away at age 81, nearly six years to the day from when he was inducted into the Cryptologic Hall of Honor.

“The enduring security of our Nation would not be possible without the foundation set by those who came before us. Lt Gen Kenneth Minihan was a cornerstone of that foundation,” said LTG Hartman, Acting Commander, USCYBERCOM, performing the duties of the Director, NSA/Chief, CSS. “He defined what it meant to be a leader in a changing world, a legacy forever solidified in the history of NSA and our country.”

Lt Gen Minihan served at the highest levels of the Air Force and the Pentagon, culminating as Director of the Defense Intelligence Agency (DIA) and eventually NSA as its 14th Director. A Vietnam veteran and Cold War warrior, his service stretched across three decades of conflict and change.

“There were few military leaders in intelligence as dynamic as Kenneth Minihan,” NSA historian Dave Hatch said. “He enjoyed his position as DIA Director, but he understood the issues NSA faced at the time and knew how the organization operated. He was ready for the challenge.”

According to Hatch, in the mid-1990s, with the Cold War over, many senior leaders in the U.S. defense and intelligence communities desired a National Security Agency that was ready to meet rapidly changing world affairs and the evolution of communications technology. They sought a leader who could push the Agency to regain its technical and intelligence production edge.

“Lt Gen Minihan perceived that success in meeting these challenges required greater cooperation between both of NSA’s major mission organizations,” Hatch said. “To capture this sentiment within the workforce, he coined the slogan, ‘One Team, One Mission.’”

His other achievements while serving as Director included transitioning NSA away from its WWII blueprint and preparing the Agency for an era in which cyberspace would become a domain in its own right. He also introduced NSA to an outside world needing to understand its purpose and outcomes.

His efforts included doubling the size of the National Cryptologic Museum and dedicating the National Vigilance Park in 1997 to ensure that the sacrifices of past cryptologists would not be forgotten.

The Hall of Honor remains among his crowning accomplishments. He joined LTG Ralph Canine and ADM Bobby Ray Inman as the only former NSA Directors recognized in the Hall of Honor.

“Lt Gen Minihan should be remembered and honored as the leader who remade NSA after the Cold War,” Hatch said. “He prepared the Agency to deal with the problems and possibilities of a new era.”
