The FRU was re-commissioned as Indian Naval Air Squadron (INAS) 550 on 17 June 1959.  The Squadron then had ten Sealands, ten Fireflies and the three HT-2s on its strength. 

The HT-2s served till 1964 when they were 'phased out'. Since the HT-2 had a long career of another two decades in the Indian Air Force, it is assumed that the three aircraft were returned to IAF service.
