Comments: INS Pondicherry was painted white and used as the Presidential yacht for the Fleet Review by President R. Venkataraman, on 15 February 1989. She reverted to her normal role and colour on completion. One vessels serves as an AGI (intelligence collection ship). The last six vessels were delivered out of pennant order. These vessels constitute the 19 and 21 MCM Squadrons. M61 - M66 are based at Mumbai and M67 - M72 are based at Vizag. These vessels carry three types of sweeps - TEM-3, AT-2 and MT-1 which are streamed from their quarter-deck. The ship's hull is made of special U3 steel to reduce its own magnetic signature. These sweeps act as mine-counter equipment and can detect various types of mines such as electro-magnetic influenced mines, acoustically influenced mines, moored mines, etc. The TEM-3 and AT-2 sweeps simulate various signatures that a ship might produce, which in turn causes the mine to explode.
The Times of India reported on 09 January 2006, that eight of the vessels are planned to be decommissioned between 2006 and 2008, while the remaining four are undergoing mid-life refits to extend their operational life. India PR Wire reported on 08 January 2008, that Thales of France has signed a $50 million deal, which will involve refitting four to six Pondicherry Class minesweepers into advanced mine hunters. The sonar suites and combat systems will be replaced, which will give the upgraded vessels leading edge capabilities. These vessels are equally divided between the Western and Eastern Naval Commands, but it is unsure which boats will undergo the mid-life upgrade. What is certain however, is that the refits will take place at Visakhapatnam and thus it is likely that the upgraded vessels will be the ones that are currently stationed there. Officials from Thales Underwater Systems will conduct the refits in collaboration with the Indian Navy and the project will reportedly take four years to complete.
