It's likely that they haven't finalized the design and subsystems yet. Also Vizag class with around 8200 ton displacement had 48 barak-8 and 16 brahmos, if P-17b "frigates" are going to be 8000 tons , what kind of number can we expect.

This is most likely the file getting warmed under some baboo's behind awaiting CCS clearance.

subsystems, sensor, weapons fit is sem2sem.

Design must be different if the 8k ton displacement rumor is true
They could go for 2x heli hangars, heavyweight torpedos aside from more quantity of missiles

but the way the GRSE and MDL bosses say "P17A repeat order" in their transcripts me thinks the hull will be the same only missile maybe increased

with the same power back,the P-17A's speed was down to around 27-8 knots ...so no much more displacement increase would be more reasonable.

P-15B's total installed power with COGAG system - 4 Zorya-Mashproekt DT-59 reversible gas turbines each producing 16.55 MW + 14.8 MW from diesel engines + 4 MW from generator sets for a total of ~85mw. It's top speed is in excess of 33 knots. power/weight = 85000/8200 is 10.36kw/t

P-17A's total installed power with 2 GE LM2500+ gas turbine, each capable of producing 30,200 kW + 2 MAN diesel engines each producing 6mw for a total of ~72.4MW. power/weight = 72400/6670 is 10.85kw/t. So it has scope for more displacement.

And I think the 27-28 knots figure for P-17A is wrong.

P-17/A is codog...and again. the best reference is P-17 -> P-17A evolution

Kolkata Vizags have displacement of 7300 tons.
Some monkey on wikipedia has changed it to 8200 tons for whatever reason recently

Still P-15B gas turbine power is 66.2MW [~9.07kw.t] v/s P-17A's 60.4MW [~8.93].

Maybe scope to remove RBUs on P17B and limit displacement increase to around 7000t6800t.

Even P17 (Shivalik, CODAG) top speed is listed as 32 knots with 2 LM2500+ and 22 knots on diesel.
