The Naval Ordnance Test Unit (NOTU) at the Cape Canaveral, Florida, Air Force Station supports and tests sea-based weapons in a safe environment. The unit also operates the Navy Port at Port Canaveral, supporting submarines and surface ships of the U.S. Atlantic Fleet and of foreign navies, as well as the assets of the Military Sealift Command. The unit's location, which is surrounded by ocean on three sides, poses a challenge for electronic devices to operate dependably due to its corrosive, salt-water environment.
