Crypto Duty at Rocket City

When one hears the name, Rocket City, places like Titusville, Florida or Houston, Texas may come to mind due to their association with the NASA space program. Rocket City, however, had nothing to do with America’s space program. It was the rocket attacks name that was given to the U.S. Airbase at Da Nang during the Vietnam War in what was then, South Vietnam. Da Nang was one of the largest U.S. bases in South Vietnam during the Vietnam War. During the years of 1965-1973, there were 87 rocket attacks with a total of 996 rockets fired against the Da Nang airbase by enemy forces. These 996 rockets inflicted injuries to 586 Americans and killed an additional 45 more. In addition to the number of casualties inflicted on U.S. personnel, a total of 256 aircraft were damaged and an additional 30 more had been totally destroyed.It was in February of 1967 when I was assigned to Naval Communications Station Philippines (NCSP), Det Bravo, at Da Nang, Vietnam for a six months of temporary assigned duty (TAD). NCSP, located at San Miguel, Zambales, Philippines, was one of the largest and busiest naval communications stations in the world during the Vietnam War.

My duties as a communications (cryptologic) technician would include flying missions, as one of 30 crewmembers, with VQ-1 that was headquartered in Atsugi, Japan. VQ-1 was a naval air reconnaissance squadron that flew in support of Operation Rolling Thunder, the bombing campaign against North Vietnam from March 2, 1965 to October 31, 1968. Rolling Thunder was the longest bombing campaign ever implemented by the U.S. Air Force and Navy during the Vietnam War. The aircraft used by VQ-1 during Operation Rolling Thunder was the EC-121M, a converted Lockheed Super Constellation passenger plane that was commonly used in the 1940’s and 50’s. We referred to this aircraft as the ‘Connie’. It consisted of a crew of 18 to 30 personnel depending on the electronic tasks involved in our missions. During the time that I served with Det Bravo, I flew 38 missions with VQ-1.

Our flights were usually eight or more hours in length flying over the Gulf of Tonkin near and around the North Vietnamese port city of Haiphong. Our crews consisted of specialists in Morse code intercept along with Russian, Chinese and Vietnamese linguists who monitored voice intercept from the surface to air missile (SAM) sites in North Vietnam. Our plane also had the capability of establishing the coordinates of our downed pilots who were shot down during their bombing missions and relaying this information to the U.S. 7th Fleet in the South China Sea below. This information was vital to determine if a rescue attempt could be made.

During the six months that I served at Da Nang, there were three rocket attacks made against the airbase by enemy forces. The most severe rocket attack at Da Nang during the Vietnam War had occurred on July 15, 1967 when the enemy forces fired 83 rounds of 122mm and 140mm Russian manufactured rockets on to the airbase. There were 175 casualties during that attack and 44 of them were personnel of Det Bravo and VQ-1. Our barracks happened to be located about 50 yards from a bomb storage area that was ignited by one the rockets that had exploded there. The bunkers that we had constructed did not have roofs on them at the time, so the shrapnel from the exploding bombs rained down into our bunkers. Fortunately, no one was killed but our barracks was totally destroyed. After the attack, the personnel of Det Bravo were transferred to another area located near Da Nang Harbor called Camp Tien Sha. It was near the R & R area at China Beach. China Beach was a favorite place for many G.I.s, especially when the pretty American nurses were there. We referred to them as round eyes.

I was only at Da Nang for six months of my life but it was six months that I will never forget. Compared to the Vietnam combat veterans, I had easy duty while I was in Vietnam but I served with honor and felt that both Det Bravo and VQ-1 had performed their assignments with exemplary dedication in support of the U. S. war effort.

In conclusion, I would like to pay a special tribute to all of the Vietnam veterans and also to the VQ-1 crew that was shot down by North Korea over the Sea of Japan on April 15, 1969. I had flown with some of that same crew while I was at Da Nang, including the plane commander, Lt. Cdr. James Overstreet.
