Programmes: The first of three modified Delhi class was laid down in 2003 but progress since her launch in 2006 has been very slow. Approval for construction of four Project 15B ships was given in May 2009. The ships are to be to a modified design of Project 15A ships. A contract is expected in 2013.
Structure: Designed by the Indian Naval Design Bureau, the design appears to be a development of the Delhi class incorporating some features of both the Talwar and Project 17 frigates.
Operational: Sea trials of Kolkata are expected to start in 2013.
