38.411839, -122.753816

38°24′43″N 122°45′14″W

(LINK). (LINK) “The former munitions magazine ("bomb dump") of Naval Auxiliary Air Station Santa Rosa was converted by the Federal Civil Preparedness Agency in the 1950s into a semi-hardened Federal Regional Center and communications facility.

In the early 1970s, the Defense Civil Preparedness Agency established a regional office facility in two 1880s-era cavalry barracks (Bldg # 104 & 105, on Montgomery St) located on the Presidio of San Francisco -- a 'soft' facility, other than the semi-hardened communications & operations center in the the basement, which seemed to rely on this Santa Rosa facility as their HF radio annex in this era.

In the late 1960s/early 1970s it was proposed that the OCD shut-down this Santa Rosa facility and build a brand-new, sophisticated hardened underground Federal Regional Center at the recently vacated Central Intelligence Agency Foreign Broadcast Information Service site a few miles away near Healdsburg. For what were probably budgetary and financial reasons, that was not done & this site remained in service.”

The location is roughly approximate.

39°42′43″N 77°58′23″W

The HAG2 Site is equipped with tropospheric scatter antennas on top of a hardened nuclear bunker which housed the communications equipment. Due to the heavy presence of Continuity of Government facilities, including Site C and Raven Rock, HAG2 served as an auxiliary link for them. In addition to serving as an auxiliary relay station, HAG2 was the northernmost station that connected to the Long Lines in the Northern United States.

AT&T “Netcong” Bunker

40.865439, -74.679222

40°51′56″N 74°40′45″W

For more than a decade, this was the principal network operations center for AT&T. It is located on a hilltop in Netcong, New Jersey, not too far from the company’s later control center and headquarters in Bedminister and Basking Ridge. The Netcong center is in a 86,000 square foot, two level subterranean building, with walls of concrete more than 2 feet thick, and entirely cased in steel. Communications lines once branched out from here all over the land, and through microwave links in the tower. The facility included accommodations and supplies for the 30 people who operated the center to live underground for up to three weeks.

Hawes Radio Relay Site, March AFB Detachment (SAC Giant Talk 46)

34.917547, -117.376885

34°55′03″N 117°22′37″W

From the 1960's to the 1980's the site was part of the military's SLFCS and GWEN emergency communication networks, used for low frequency communications by the Strategic Air Command.

Equipment included a 1,226 foot tall tower, and a two level underground bunker full of power and communications equipment. When the tower was torn down in the mid 1980's, the lower half of the tower fell sideways and the top half of the tower collapsed onto the bunker. Until recently, portions of the top half of the tower could be seen protruding from the roof of the bunker. The tower and the equipment were scrapped, and the underground bunker was left open and exposed to scavengers. It became a party spot, covered in graffiti, until 2008, when two local teenagers were murdered after attending a party there. The Air Force and the BLM demolished the remains, and filled in the underground parts.

Barksdale Communications Annex (SAC Giant Talk 46)

“This facility was phased out as the USAF proved that AFSATCOM was a more effective communications medium during Project ELF One. Quasi decommissions in 81 and 82 (Top Secret Gear ripped out), and then used for 2-3 years after that for Secret and Confidential materials, and then fully retired and the antennas taken down.”

42°09′55″N 93°47′39″W

“On the surface is a microwave relay tower, built as part of AT&T’s nationwide communications system in the 1960s. The bunker here, with around 20,000 square feet, was larger than a typical relay station, as it housed equipment for the AUTOVON system, which was a military communications network that existed independently of AT&T’s civilian network. Additional security included thicker walls, more space, bigger blast doors, and spring loading for equipment rooms.”

AT&T AUTOVON Tower (Fairview, KS)

39.758747, -95.733007

39°45′31″N 95°43′59″W

“An AT&T Long Lines site, one of hundreds that were part of its long distance network, using microwave transmission. This site is a bit unusual, as it was also one of a few dozen AT&T transmission sites that were part of the AUTOVON, a military communications system. This site, in Fairview, may have been especially critical as it provided a connection point to the national Long Lines and AUTOVON system with Offutt Air Force Base, 90 miles north. There is an underground bunker here.”

Office of Censorship Bunker

39°34′58″N 77°00′10″W

“A now unoccupied bunker below the basement of the Lewis Hall of Science at Western Maryland College is an interesting case in point. This 6,000 square foot chamber, accessed by elevator, and equipped with a broadcast facility connected to FEMA’s communications infrastructure, was for the leaders of the United State Office of Censorship, later renamed the Wartime Information Security Program. In the event of a war, a group of eight appointed individuals, and a staff of 40, were to convene at this location to assume their duties leading the national censorship of news broadcast and print media, according to federally mandated emergency guidelines, listed in manuals and code books stored in the bunker. One of the directors of this program was the Vice-President of CBS.”
