Six HEMP shielded facilities, including two at a remote island in the Bering Sea. The total square footage was in excess of 85,000 SF and included 24 HEMP doors, 89 RF electrical filter cabinet assemblies with MOVs, multiple waveguide penetrations, Pulse Current Injection Testing, RF Attenuation and SELDS testing. Completed 2004.
Space Fence Lockheed Martin
European Phased Adaptive Approach, Phase III
Design, fabrication, and installation of shielding to mitigate the effects of Electromagnetic Interference (EMI) within the Space Fence Sensor Site in Kwajalein Island
Design, furnish and constructed EMI shielded systems. The project is comprised of 4 EMI Shielded Volumes to include the Transmit (Tx) Building, Receiver (Rx) Building, Common Services (CSF) Building and the Operations (OPS) Building. The shielded plate is a SS316L steel grade to meet the 25-year life cycle requirement. Total shielded square foot area includes approximately 95,000 square feet. ATEC also furnished and installed all wave-guide pipe penetrations, mechanical air vents, electrical filters and double door vestibules for equipment and personnel access.
