I don't get why the IN insists on calling these 'stealth frigates'! An angled hull alone doesn't make a ship stealthy. The Russians probably used this ship as a test case for RCS reduction but the topside design, especially that lattice mast, beats the whole purpose.
She may have been designed in the late 90s but even the IN's Delhi class are the same vintage. The least we could have done is ask for an enclosed mast like on the newer Grigorivich class. Hopefully, we'll move to an integrated mast soon enough and clean up the aesthetics a bit. Sorry about the rant!
