Breaking News :- RFI Issued for seven next generation Corvettes.

[Penguin]

There requirement was almost of a corvette but it seems lower end of Frigate.
Similar to Godavari class

Considering when she was designed and on what basis, Godavari - which is longer than Talwar and of similar structural dimensions and displacement - is a full fledged frigate. Much like the ex-Dutch Van Speijk class now in Indonesian navy service.

https://en.wikipedia.org/wiki/Godavari-class_frigate

Godavari was designed to take 2 Sea King, NGC RFP makes reference to a rotary UAV and alternately a ALH/NUH helicopter (=Hal Dhruv) , hangar, capability to rearm the helicopter with light ASW torpedoes.

Westland SeaKing HAS5

• Empty weight: 6,387 kg (14,051lb)
• Loaded weight: 9,525 kg (21,000 lb)
• Max. takeoff weight: 9,707 kg (21,400 lb) (overload weight)

Hal Dhruv

• Empty weight: 2,502 kg (5,515 lb)
• Useful load: 2,600 kg (5,731 lb)
• Max. takeoff weight: 5,500 kg (12,125 lb)

So, not just 2 versus 1 helicopter but also 2 much larger helicopters. (i.e. the flight deck can probably handle Sea King but not the hangar)

I didn't look at the " Rotary UAV" part. Thanks for pointing it out.

What are the options if we are actually looking for a Rotary UAV, which can take off from ships at sea with a load of sensors ?

 

[MKC]

That could be a possibility.


Talwar displacement:

• 4,035 t full load
• 3,850 t standard

NGC displacement:

• "as per design"

Talwar is 124.8 m
NGC is <120 m

Talwar crew is 180 (18 officers)
NGC crew is 158 (21 officers)

Talwar range and speed

• max speed 32 knots
  
• 4,850 mi (4,210 nmi) at 14 kn (26 km/h; 16 mph)
• 1,600 mi (1,400 nmi) at 30 kn (56 km/h; 35 mph)

NGC range and speed:

• max speed 27+ kn
  
• 4,000+ nmi at 'sustained economical speed' (12-14 kn?)
  
• 1,200 nmi at 25 kn (= max sustained speed)

Talwar endurance: 30 days
NGC endurance: 14+ days

In short, Talwar is a bigger ship, with greater speed, range and endurance.
(Sorry, can't be bothered with weapons and sensor comparison)

That's what I was saying.
It has all of capabilities of Talwar except RBU.
Though small torpedo, smaller hanger, somewhat less speed.
But I think endurance & range difference doesn't make much sense as such ship don't require much range & endurance.
Even if we turn Kamorta in ASuW configuration than also NGC seems much better.
For me, it seems more powerful than F22P in every aspect, at least on paper.

IAI Naval Rotary UAV (NRUAV)

https://en.wikipedia.org/wiki/IAI-HAL_NRUAV

This would be an interesting option because it allows IN to recycle Aérospatiale SA 316 Alouette III / HAL Chetak

Why is it breaking news?

It will take another decade to get all of them in.
