Nov 1954, immediately after completing flight training as an Electronic Countermeasures (ECM) officer at Keesler AFB, MS.
I was immediately assigned to HQ USAFSS in San Antonio for 2 months indoctrination and reassigned the 1st RSM, later designated 692lst Radio Squadron Mobile (RSM) Misawa AB, Honshu, Japan as ELINT officer. During my stay at Misawa, I flew the minimum required 4 hours/mo in a variety of aircraft such as: C-47, C-119,
L-20 and B-26C. The most productive missions were flying B-26 photo recon of foreign national ships that passed through the Tsugaru Strait (between Honshu and Hokkaido island ) in support of a US Navy mission. Occasionally the pilot I flew with was Major Bill Madole, C.O. of the 6921st RSM. My additional duties included: military pay officer, courier officer and security violation investigative officer in support of 2 remote USAFSS sites (Det 1 and Det 3) on Hokkaido, Japan.

Aug 55-Oct 55, I was reassigned as Commander, Det 4, 6921st RSM, a 15-man test team at Henashi Saki, at a remote location on the north-west coast of Honshu, Japan. In Oct 1955 the site was closed because a Misawa AB Hospital inspection of the troop housing accommodations (a Butler Hut) were deemed unhabitable during severe winter weather. As you see by the photos, the site was quite primitive and had little to offer the personnel there. See photos...

Nov 55, I was reassigned to Det 2, 6921st RSM at Wakkanai Air Station on the most northern tip of Hokkaido, Japan. My primary duty was ELINT Officer. During my short tour at Det 2, I was given numerous additional duties, including: Det 2 Supply Officer, Motor Pool Officer, Alternate Crypto Custodian, Fire Marshal, Ground Power Officer, Ground Defense Officer, Alternate Custodian of Registered Documents, Alternate Top Secret Control Officer for Top Secret COMSEC Materials, and miscellaneous other duties as assigned. I returned pre-maturedly to the United States on Emergency Leave to attend my father's funeral. See photos...




 

NOTES:
1. In May 1955, the 1st RSM became the 6921st RSM and just two months later was redesignated the 6921 Radio Group Mobile (RGM). The 6989 RSM was activated at Misawa along with the 6986 RSM at Wakkanai, Japan. Both were under the direct control of the 6921 RGM.

2. Det 2, 6921st RMS was collocated with the 848th AC&W Squadron, 511th Air Group at Wakkanai AS, Japan. Det 2 was one of 29 US Air Force Security Service (USAFSS) Sites located around the world.


3. In Aug 1956, I was reassigned to the 9th Tactical Reconnaissance Squadron (TRS) at Shaw AFB, SC as an Electronic Warfare Officer. Initially we flew in RB-25s and RB-26s until the RB-66s arrived. I spent the next 10 years at Shaw AFB and culminated my E/R/B-66 assignments as Chief of the 363rd Tac Recon Wing Standardization & Evaluation Section at Shaw AFB.

4. I also served 4 years at Hq NSA, Fort Mead, MD and 3 years (1974-1977) as Deputy Director, Department of Defense, Special Representative (DoDSpecRep) Office,
Camp Zama, Japan

Note: Classified Information Notice: Information about USAFSS activities was cloaked in secrecy until September 1997, when the veil was lifted. Since then, several TV programs have told its story, along with a number of military magazines, websites and books. Equipment involved in the science of cryptology during this time period is on public display at the National Cryptologic Museum at Fort Meade, MD on the grounds of the National Security Agency (NSA).
