The Tracker was eventually superseded in U.S. military service by the Lockheed S-3 Viking; the last USN Tracker operational squadron (VS-37 with S-2G models) was disestablished in 1976.
The last Navy S-2 was withdrawn from service on 29 August 1976.
For many years the TS-2A version of the Tracker was used by U.S. Navy training units, culminating with its use by Training Squadron 27 (VT-27),  Training Squadron 28 (VT-28) and Training Squadron 31 (VT-31) for Student Naval Aviator training in the multi-engine pipeline with Training Air Wing FOUR (TRAWING 4) at Naval Air Station Corpus Christi, Texas.

A number of Trackers live on as firefighting aircraft while the design also continued to provide excellent service with the naval forces of other countries for years after the U.S. retired them.
For example, the Royal Australian Navy continued to use Trackers as front line ASW assets until the mid-1980s.
