In January, 1952, the U.S. Naval Radio Station, Sabana Seca was officially designated, with LCDR W. L. Thomas, as the Officer-in-Charge.
In the month, a U.S. Naval Security Group Detachment (NSG Det) was established, co-located with the Naval Radio Station (NAVRADSTA) at Sabana Seca. Later in 1952, the NAVRADSTA was recommissioned as Net Control Station (NCS) Puerto Rico, Sabana Seca, PR, and the NSG Det became the NSG Dept, NCS Puerto Rico, Sabana Seca, Puerto Rico.
On July 1, 1971, the U.S. Naval Security Group Activity Sabana Seca Puerto Rico was commissioned, under the command of CAPT Robert G. Keller. The guest speakers at the commissioning ceremony were RADM Chester G. Phillips, COMNAVSECGRU; RADM Norvell G. Ward, Commandant, Tenth Naval District; and CAPT Griffith P. Stokes, Commanding Officer of Naval Communications Station (NAVCOMSTA) Puerto Rico.
Marine Cryptologic Support Battalion, Company G and U.S. Air force 544th Intelligence Group Detachment 2 were both co-located with NSGA Sabana Seca until NSGA Sabana Seca was deactivated on January 31, 2003. When the station closed Company G was transferred to NSGA Menwith Hill Station UK.
The Terrorist Attack
On December 3, 1979, at 6:40 AM, terrorists attacked unarmed sailors en route to a day watch at NSGA Sabana Seca. Volunteered to drive the Navy bus was CTO1 John Ball, the Communications Supervisor; seated directly behind him was RM3 Emil White. As the yellow bus rolled out of the U.S. Navy compound in Toa Baja, a San Juan suburb, the passengers – 13 men and five women – dozed or talked quietly as they traveled the familiar route from the Sabana Seca Communications Station to a radio transmitter site four miles away. Nobody paid any attention to a green pickup truck that was following close behind. About a mile from Sabana Seca, the truck suddenly accelerated. It passed the bus, slowed, and forced the bigger vehicle to a halt beside a trash dump.
Simultaneously, a white van that had been parked down the road came roaring toward the scene and the blast of automatic weapons fire shattered the dawn silence. The attack from the white van lasted for 30 seconds “a lifetime,” said one survivor. Of the 17 sailors on the bus, CTO1 John R. Ball, 29, of Madison, WI and RM3 Emil E. White, 20, of Charlotte Amalie, Virgin Islands were both killed by the gunfire. When it was over two U.S. sailors lay dead and ten other sailors, including all of the women were injured. Credit for the savage attack, the worst outbreak of political violence in Puerto Rico in two decades, was claimed by three terrorist groups that favor Puerto Rico’s independence from the U.S.: the Volunteers for the Puerto Rican Revolution, the Boricua Popular Army, and the Armed Forces of Popular Resistance.
Hurricane Damage
The U.S. Naval Security Group Activity Sabana Seca maintained and operated a high frequency direction finding (HFDF) facility and provided communication support to Navy and other Department of Defense elements. The communications facility located on the island included an operations building located in the center of an AN/FRD-10A Circularly Disposed Antenna Array (CDAA), also known as a Wullenweber antenna array. The AN FRD-10A CDAA was heavily damaged by Hurricane Georges in 1999.
NSGA Sabana Seca ceased HFDF operations and the Wullenweber was dismantled and removed in 1999. The CDAA property was sold and is now being developed by a commercial enterprise.

For me and those I was stationed there with who have blamed me for whatever bad behavior I did there, I have suffered a lifetime of shame and mental anguish that isn’t deserved. As for the NCIS investigation that destroyed our lives, I’m sorry I wasn’t more mature at 21 y/o, but no young American Sailor should be placed in that situation of a Top-Secret Clearance being taken away with more taxpayer money wasted by the American Military, or Government, like I was. The anonymous death threats on Twitter exhibited toward me was enough. please forgive & forget. Just know I am fighting for vets and so that never happens to young Sailors ever again. I don’t have much left so not much to take away.

Karen Laino. I was stationed at NSGA Sabana Seca from 1990 to 1993. I met so many beautiful people of the Island and still maintain contact with them to this date. I just lost my best friend that lived and was stationed at the base. He was a Marine.

Hello. Our family was stationed in Sabana Seca shortly after I was born in Augsburg (82). We we fortunate to be there for 3 years and spend time with our Puerto Rican family. I now have the opportunity to return, with my own wife and children, and was hoping to show them my childhood home and how base living was. Unfortunately, I found that the base is closed. Does anyone know if it is possible to visit the closed base and how I would go about it? Any information would be greatly appreciated. Thank you.

You could look up the Sabana Seca group in Facebook and will notice most of the buildings have been demolished. The building at the main gate is still standing. But for that you don’t need to go in. Bldg 85 at North Tract is still up but the access road is blocked. The Wullenweber was dismantled on Sept 2001. Roosevelt Roads was decommissioned. There is access to some parts of that base. Ft Buchanan is operating normally.

It appears very few people realize that a small Army Security Agency detachment was very hurriedly deployed to NavRadSta Sabana Seca and worked in the same facilities and housed in the same barracks with the NSG beginning in 1962 until ? We were part of a Direction Finding Network.

The Army Det appears to have been there beginning in 1962 until at least 1967. Lee Falvey in the Sabana Seca – Puerto Rico – US Naval Security Group Facebook group remembers a small Army complement in Bldg 40 when he was there 1965-67.
