The Seaward-class defence boats are large patrol craft designed by Mazagon Dock Limited (MDL) and built by Garden Reach Shipbuilders and Engineers (GRSE) for the Indian Navy.

All of these vessels have been decommissioned, due to the large maintenance overhead they require.

Ignoring the vulnerability to corrosion of this ship, the medium refit was delayed by over three years and was carried out from July 1991 to April 1992.

However, another short refit including the replacement of the engines was taken up in December 1993.

While carrying out repairs, extensive damage to the hull below the waterline was noticed in March 1994.
