AN/ASN-30 Antisubmarine Tracking Computer

This is the CP-63 analog computer component of the AN/ASN-30 Anti-Submarine Tactical Navigation System (ASWTNS). It was used on an Grumman S-2 Tracker ASW (Anti-Submarine Warfare) aircraft, which entered service in the 1952 as a carrier-based plane. The ASWTNS was an electro-mechanical navigational and tactical computer and display system designed to solve ASW plotting, display and tactical co-ordination problems. It utilized both automatic and manual inputs to compute and display solutions to both navigation and tactical ASW actions.
