W81B

W81B is a designation used by the United States Department of Defense to categorize a specific type of military-relevant electrical and electronic products. The W81B designation is assigned by the U.S. Army to products that are primarily used for communication, cryptographic, and electronic warfare applications.

Products designated with the W81B code are typically associated with complex electronic systems, including signal processing, encryption, and decryption technologies. These systems often involve the deployment of advanced communication networks, HF and VHF antennas, and various types of transmission and reception equipment.

W81B products are also associated with development, manufacturing, and testing of military electronic systems. These include various types of miniature components, circuit boards, and rack-mounted systems. The range of products encompasses electronic warfare systems, direction-finding systems, communications systems and antennas.

Devices with W81B designation have been mainly sponsored by the U.S. Army and the Defence Intelligence Agency (DIA). Many W81B contracts are let by Army Contracting Command – Aberdeen Proving Ground (ACC – APG). These contracts often feature specification requirements, performance, interoperability and repairing standards.
