The AN/USQ-17 or Naval Tactical Data System (NTDS) computer referred to in Sperry Rand documents as the Univac M-460, was Seymour Cray's last design for UNIVAC. UNIVAC later released a commercial version, the UNIVAC 490. That system was later upgraded to a multiprocessor configuration as the 494.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/USQ-17" designation represents the 17th design of an Army-Navy electronic device for general utility special combination equipment. The JETDS system also now is used to name all Department of Defense electronic systems.
