Birth of a Situation Room

Sometimes major advances in the intelligence world take place simply through luck of the draw — in this case the creation of the White House Situation Room in the spring of 1961. The whole evolution took place over just a few months, thanks largely to then-Chief of Naval Operations Admiral Arleigh Burke and the Navy Seabees.

Joint Intelligence Center, Pacific (JICPAC) – Thinking Back 30 Years

By Vice Admiral Lowell “Jake” Jacoby, U.S. Navy (Retired)

In the years following the creation of JICPAC, there was plenty of misinformation and myth surrounding the consolidation of service intelligence units, including the Navy’s fleet ocean surveillance intelligence centers, into joint intelligence centers. This is what really happened, and why.

Oral History/Interview with RADM Mac Showers

Provided by Museum of the Pacific War

The National Museum of the Pacific War presents an oral interview with Donald Mac Showers.. He joined the Navy after finishing school at the University of Iowa in August 1940. He signed up for the V-7 program and was commissioned an ensign in September 1941 after Midshipman School at Northwestern University. His first assignment took him to the intelligence center at the 13th Naval District in Seattle. He stayed in Seattle for six weeks hoping to get in with the public relations section. Instead, he was sent to fill a billet in the combat intelligence unit in the 14th Naval District in Hawaii, reporting to Commander J.J. Rochefort. Showers discusses breaking the Japanese Naval code (JN-25) at Station HYPO, at Pearl Harbor. He recalls the origins of the ruse involving fresh water at Midway to determine what AF stood for in the JN-25 code. Showers also comments on the dysfunctional torpedoes used early in the war. He also discusses the role of intelligence gathering in the Battle of the Coral Sea, the Battle of Midway and Operation VENGEANCE. Showers describes the emergence and flexibility of JICPOA (Joint Intelligence Center Pacific Ocean Areas) in Hawaii and the need for various intelligence gathering apparatus (communication intelligence, photo reconnaissance, etc.) to function together. He also discusses the use of atomic weapons and the plans for invading the home islands of Japan. He also comments on what it was like to work closely for Admiral Nimitz. After the war, Showers remained in the Navy and became an intelligence specialist whose primary focus became the Soviet Navy during the Cold War. Showers retired from the Navy in 1971 and went to work as a civilian for the Central Intelligence Agency, retiring in 1983.

by J. Michael Dahm, senior national security researcher at the Johns Hopkins University Applied Physics Laboratory

H053.3 Operation Desert Shield/Desert Storm – Part Two (September 1990)

By Sam Cox, Director of Naval History, 6 August 2020

This series is a departure from my normal H-grams in that this is a personal recollection. I was the Iraqi Subject Matter Expert on the Intelligence Staff of Commander, U.S. Naval Forces Central Command for the entirety of Operations Desert Shield and Desert Storm, serving under VADM Hank Mauz and VADM Stan Arthur. I first wrote this a number of years after the fact but I kept it true to what I believed and understood to be true at the time, so my dim view of Joint Operations as conducted during Desert Storm (which held the Navy back from making maximum contribution to the war) and U.S. Central Command, particularly the Intelligence Support Architecture, will be readily apparent. My penance for this heresy was to spend 12 of the next 21 years in joint commands, including three years as Commander of the U.S. Central Command Joint Intelligence Center, in which I had the opportunity to see vast improvement in U.S. Joint Operations.

H053.2 The Surrender of Japan

By Sam Cox, Director of Naval History, 2 September 2020

At the time of the first atomic bomb on Hiroshima, senior decision-making authority in Japan was vested in the six-member Supreme Council for the Direction of the War, three of whom were active duty or retired Imperial Japanese Navy admirals. The ultimate decision-maker in Imperial Japan was Emperor Hirohito, whom the Japanese believed to be divine. However making mistakes is bad for a divinity’s reputation, so the Emperor only directly intervened on rare and extremely important matters. Emperor Hirohito was routinely kept informed of the course of the war, and it became increasingly common for senior leaders of the Army and Navy to apologize to the Emperor when something went badly. Nevertheless, the Emperor rarely directly told any government, Army or Navy leaders what to do.
