Transhield has collaboratively developed with Naval Surface Warfare Center Port Hueneme Division drapable electromagnetic spectrum (EMS) shielding technologies. These technologies can 1) prevent interrogation by blocking or attenuating malicious EMS signals, 2) manage EMS signatures by blocking emissions and reducing signatures, 3) prevent damage or alteration to critical asset by clocking microwave directed energy weapons or an electromagnetic pulse and 4) alter signatures to deceive adversaries by managing signatures or the development of decoys.
