FF 1052 KNOX class

The Knox-class frigates, all of which have been retired, fulfilled a Protection of Shipping (POS) mission as Anti-Submarine Warfare (ASW) combatants for amphibious expeditionary forces, underway replenishment groups and merchant convoys. The Knox-class frigates initially formed the backbone of the Innovative Concept Reserve Training Program. Under this program, the last eight ships remaining in service were designated Type II Reserve Training Frigates [FFT], while 32 other frigates were deactivated and designated Type III ships. The Type III ships can be completely reactivated in 180 days. Each of the eight Reserve Training Frigates ship had its own reserve crew, and was also assigned four "nucleus crews" which would man the 32 Type III ships. The Reserve Training Frigates ships were to be homeported in New York, Mobile and Ingleside Texas. The Reserve Training Frigates were all inactivated in 1994, and some of them have been disposed of through the Security Assistance Program (SAP) foreign military sale program. Replacing the Knox-class frigates in this role, by the year 2000, seven of the 10 FFG-7 Oliver Hazard Perry frigates in the Naval Reserve Fleet will be modernized to the Flight III baseline. These ships fulfill an important role in reducing the Active force's operational and personnel tempo by responding to contingencies such as the Haitian embargo, counter-narcotics operations, and overseas deployments, such as Carat 96 in the Western Pacific.
