Grumman S-2T Turbo Tracker

Grumman received a contract for the conversion of 32 S-2T Trackers (from 25 S-2Es and 7 S-2Gs) in service with the Republic of China Air Force in late 1980s. Only 27 were ultimately converted due to a shortage of parts supplied by Grumman resulting in the use of remaining conversion kits as spare parts. The 27 S-2Ts were transferred to the ROC Navy Aviation Command on 1 July 1999 and while the ROCN continues to operate the type, less than half of the fleet is in operational condition, will be replaced by 12 rebuilt P-3C from US Navy.

The conversion involved: 2 Garrett/Honeywell TPE-331-15AW turboprop engines, each rated at 1,227 kW (1,645 shp), with four-blade propellers. The upgrade also included new mission equipment of AN/AQS-92F digital sonobuoy processor, A/NARR-84 99-channel sonobuoy receiver, Litton AN/APS-504 radar, AN/ASQ-504 MAD and AN/AAS-40 FLIR. The new turboprop engines resulted in a payload increase of 500 kg. Usually carries depth charges, Mk. 44, and Mk 46 lightweight ASW homing torpedoes.
