The RFI says:
Length < 200 m.
Beam Commensurate with the length and tonnage of the ship.
Draught < 08 m in full load conditions without ballasting.
Displacement Commensurate with length and draught of ship.
Did I miss something regarding displacement (40k)
No, you have not missed it, you just need to compare sought specs with existing one of INS Jalashwa.
Armament of Jalashwa includes 4 x AK630 M CIWS and equal numbers of 50cal AA gun if I am not mistaken.
Armament sought in latest RFI includes, 4 x AK630 CIWS, 6 x HMG instead of 4 in L41 and 8 x MMG
ASW capability in existing platform is zero whereas it has been sought in latest RFI.
AD system in Jalashwa is just the 50 cals AA, but IN wants 32 x VLSRSAM. On top of that 16 x SSM has also been sought which in all probability would be BRAHMOS to begin with.
On onboard crafts list, Jalashwa could accommodate 1 LCAC whreas IN wants double of it now.
INS Jalashwa could accommodate 6 HLH, but this time IN had gone for just 2. But on other hand IN indicated that the HELI could be of 40 t category or even if we operate 2 Chinooks, it would mean 44 tons against 60 ton of present. Along with that 12 special operation helis and 2 NSUAS is going to trip the scale on much heavier side then 6 UH-3.
Complement of officers and sailors is also on heavier side this time. So with maximum load L41 DWT is at 16600 tons which is easily going to get doubled in the new platform.
