The Origin & History of the 7th RRFS - Det J in  Ubon Ratchathani

 The 5th  RRU was in existence from late 1959 to September 1966.  The 5th  RRU(p) became the 83rd RRSOU in September 1966.  Detachment D of the 83rd  became the 7th RRFS and was in existence from September 25, 1966 to June 20, 1976.  After closing in October 1970 all detachments of the 83rd were assigned to the 7th RRFS.  Dets J, C and D were established in Ubon circa 1969-70 and were all decommissioned by 1976.  Due to agreements between the Thai and United States governments all ASA functions officially ceased on June 20, 1976.

The late Rich Javlosky has an excellent narrative from an Air Force DF (Directional Finding) perspective about the start of Det J in 1969 through his departure from Thailand in 1971. Visit his story.

Wikipedia has a concise narative of how U.S. forces were first 'invited' to use Thailand's airbases to conduct air strikes against the Viet Cong in Vietnam (and unofficially in Loas and Cambodia).

Is it OK now to talk about what we did?  According to Quin Allred, “Everything I did while I was in Vietnam was under an agreement that I had — well, every soldier who served in the Army Security Agency — had to sign a 40-year-nondisclosure agreement,” Allred said. “That we did not disclose anything that we did or where we were at for 40 years.”

NOTE: I'm listing Det J names, nicknames and dates (the 1970's) to the best of my recollection and certainly cannot promise acurracy.  If the term "Registered" is displayed, the individual will also have more info on our Det Contacts page (limited access - must be registered to have access and to use this page to contact fellow 7th RRFS veterans).

Hopefully,  Det J survivors will find this site and submit their registrations to help make this roster more accurate. The world should know and remember who we were.

Story by...
Anderson (excerpted from the War Relics Forum)

"...My wife and I just visited a unusual attraction in Thailand, a former US signals intelligence HF direction finding station used during the Vietnam war and commonly referred to as an 'Elephant cage'."

"But first a background. This is a huge facility. The AN/FLR-9 Antenna was a large circular array built at 8 locations during the Cold War. Collectively the 8 stations could locate and intercept HF communications anywhere on the planet, an individual station had accurate direction finding up to 7,400 km away."

"The antennae was gigantic, consisting of three concentric rings with outer ring 440 metres in diameter. The antenna two outer rings were supported by 96 pillars of 40 metre height."

"In Thailand an "Elephant cage" was built in 1970 at the tiny village of Non Sung, about 15 km south of Udon Thani in the north East region. Operated by the 7th RRFS (rather blandly described as a "Radio Research Field Station") it was really a top secret intell gathering station under the command of the Army Security Agency. In fact the 7th RRFS had been operating there since 1967. By 1970 the station had a 1,000 linguists, O5H (high speed morse intercept operators), cryptologists and communication staff. The development of the 320 acre site (which cost the US $400 to buy) cost US$50 million. Primarily purpose was listening in to NVA and Viet Cong radio traffic and monitor Chinese military movements."

"But political wind changes saw the Thai Government asking the US to close the Station in 1976, and it remained of limits to civilians until September 2018 when the Thai Army opened the Ramasun Historical museum."

 Sp5 RJ (Lefty) Riesterer (1972-73)

I was originally assigned to Ben Hou in Vietnam but ended up at Ramasun Station in Udorn, Thailand. I spent app. 3 months there before again being re-assigned to Det J duty at Ubon. I served out my duration there and tolerated the duty of VC low-level intercept fairly well (lousey xmiters, sloppy keyers, and lots of radio noise). I enjoyed the smaller duty station where you knew everybody. My closest friend was a fellow Ft. Devons graduate, Glen (Clem) Courtney, who joined the Det about four months after I arrived... 

Two stories about Glen (aka Clem) come to mind. One day in ops (the operation building), I noticed he was typing furiously during a hot intercept and had at least ten feet of "skit" (4-ply carbon-copy paper) hanging over his "mill" (typewriter). I joked he was really on fire and lit the beginning edge of his paper on fire, thinking he would immeditely get up from his pos (interecept position) and put it out. Well, cool Clem just said he wasn't a f****** fireman and calmly walked out of the ops. I, not calm at all, quickly put out the fire which luckily burned only the first page of his typed intercept but caused a lot of smoke in the small ops building. Such practical joking was common among members of the Det -- needed to relieve the stress of long hours of duty because we were so short handed.

The second story I remember is my ETS (End Term of Service) "party" where I was put on trial for daring to leave my comrades behind to go back to the world (States). Clem served as my defense attorney while our 1st. Seargent Kirkland (Top) served as the preciding judge (Top was a grand ol' guy who we all admired). And, of course, after being found "guilty on all counts" I was led to my doom -- the burn pit where I was doused in ash and water. All in good fun and the spoofed trial did become a fond memory of the comaraderie we had at the Det.

The most exciting experience that I remember was the day I got my first “CRITIC” which was the word operators (O5H20's) shouted out when they believed they were intercepting a priority message. My critic involved my "guy" (a low-level NVN field transmitter) sending a QST (“go to voice”) which usually happened when they were preparing for an attack.

When a “Critic” was shouted out, our entire shift quickly went into “critical operations mode” which meant several other operators would tune into the same frequency and backup the primary interceptor so nothing would be lost. The DF (direction finding) specialist would alert our DF aircraft to the frequency so they could triangulate the transmitter’s location. Our translators and analysists (TA's) would decode “live” and determine the intercept’s importance and relay the traffic to our Flag (our headquarters in Udorn) who would then determine appropriate counter measures - often times an airstrike. While this was a very exciting day for us, it was  a very bad day for the enemy. I only had one of these but there were other operators at the Det who had more. The following year, at Vint Hills Farm in VA, I was awarded the Army Commendation Medal for this event.

(I hope other alumni of Det J will find this site and submit their stories so all will know what we did then --both the serious and the fun-- to serve our country).
