13 August 2002. The identification of the airship dock shown below has been questioned: that it may be instead a High Frequency Direction Finding (HFDF)/SCIF facility. Several images have been added: a topographic map which names the facility and a corresponding photo; photos which show a nearby blimp; and photos of similar blimps (aerostats) used as antennas. More information welcome; send to jya@pipeline.com

In 1971, the post became the home of the U.S. Army Intelligence Center and School, bringing with it the School Brigade. The Strategic Communications Command became the U.S. Army Communications Command in 1973, subsequently changing to the U.S. Army Information Systems Command in 1984. In October 1990, the post changed hands with the U.S. Army Training and Doctrine Command became the new host command; the U.S. Army Intelligence Center and Fort Huachuca now operates the post.

Electromagnetic Interference (EMI) and TEMPEST Test Facility (Blacktail Canyon Test Facility)

Electromagnetic Interference (EMI), Electromagnetic Compatibility (EMC) and TEMPEST testing are conducted at EPG’s Blacktail Canyon Test Facility in one of its two large 120 dB anechoic chambers or one of its two 100 dB semi-anechoic shielded rooms. The test facility is located in a radio frequency (RF) isolated area ideal for open-field EMI and EMC testing and has a frequency authorization that allows for outside susceptibility and EMC testing from 10 kHz to 40 GHz.

With a door 14 ft. X 12 ft., the large anechoic chamber has a working volume measuring 35 ft. long x 14 ft. wide x 14 ft. high and is capable of accommodating large vehicles such as an M1 tank, armored personnel carriers, helicopters or multiple shelter, large platform systems. This chamber is equipped with necessary cooling and exhaust to allow for total operation of the test item while inside the chamber's controlled environment.

The second large anechoic chamber, measuring 22 ft. long x 12 ft. wide x 10 ft., high has a door size of 14 ft. high by 12 ft. wide. It accommodates military equipment ranging from manpack portable equipment to vehicles such as HMMWV, LAV, M113, and full- and half-sheltered systems.

The facility's two smaller chambers allow for testing of bench size items such as computer systems, GPS, tactical radios, chemical agent detectors, inverters, manportable items etc.

Other Assets:

- The facility is equipped to support E3 testing requirements from < 10 kHz to above 40 GHz. Radiating fields > 200 volts/meter rms.

- The facility has an authorized helicopter landing pad within its controlled perimeter and a Temporary Secure Working Area (TSWA) as needed to support project requirements.

- Blacktail has instrumentation which is mobile and has supported various testing all over the world.

- Exceptionally qualified staff: over 75 years experience, an NSA Certified TEMPEST Engineer, and several NARTE Certified EMC Engineers.

-Tests include: MIL-STD-461 (all versions), MIL-STD-462, MIL-STD-464, RTCA/DO-160, ADS-37, NACSIM-5100A, NACSEM-5112, NTISSAM 1-91, 1-92, KAG-30 and others as requested
