The only advantage in a2a I see for the NG is the Meteor missile. In a2g instead I see the Gripen in front, it will get IRST (LCA?), will have a payload of 6t (should be less on LCA), but that is not surprising though the NG is meant for the medium class, whereas the MK2 could remain in the light class.
IRST pods are available, If it is not incorporated directly into the LCA it self.
the Metor missiles is pointlessly expensive.
Compared to the American Aim-120. its not the best either to justify its cost.
Selecting for a missile will just leave us relying on a foreign supplier, even more.
I doubt India will buy any of the weapons from Europe to use on the Planes. Instead they are likely to simply modify them to use Indian Missiles. such as the AStra
In fact the only advantage the Griphen can have over the LCA is maneuverability. Due to its canards i think. AS design wise they are almost the same.
The LCA design was finalised in 1990 as a small delta-winged machine with "relaxed static stability" (RSS) to enhance maneuverability performance.
In designing the aircraft, several layouts were studied. Saab ultimately selected a canard design with relaxed stability. The canard configuration gives a high onset of pitch rate and low drag, enabling the aircraft to be faster, have longer range and carry a larger payload.
But if the LCA uses a TV engine then the LCA becomes more agile.
Aerodynamic advantages Delta wing
The primary advantage of the delta wing design is that the wing's leading edge remains behind the shock wave generated by the nose of the aircraft when flying at supersonic speeds, which is an improvement on traditional wing designs. While this is also true of highly swept wings, the delta's planform carries across the entire aircraft, allowing it to be built much more strongly than a swept wing, where the spar meets the fuselage far in front of the center of gravity. Generally a delta will be stronger than a similar swept wing, as well as having much more internal volume for fuel and other storage.
Another advantage is that as the angle of attack increases the leading edge of the wing generates a vortex which remains attached to the upper surface of the wing, giving the delta a very high stall angle. A normal wing built for high speed use is typically dangerous at low speeds, but in this regime the delta changes over to a mode of lift based on the vortex it generates. The disadvantages, especially marked in the older tailless delta designs, are a loss of total available lift caused by turning up the wing trailing edge or the control surfaces (as required to achieve a sufficient stability) and the high induced drag of this low-aspect ratio type of wing.
This causes delta-winged aircraft to 'bleed off' energy very rapidly in turns, a disadvantage in aerial maneuver combat and dogfighting. This can be solved with relaxed stability, strakes and canards.
Additional advantages of the delta wing are simplicity of manufacture, strength, and substantial interior volume for fuel or other equipment. Because the delta wing is simple, it can be made very robust (even if it is quite thin), and it is easy and relatively inexpensive to build - a substantial factor in the success of the MiG-21 and Mirage aircraft.
well both are highly agile.
But i don't know of any Delta wing aircraft with TVC
And the Griphen has both Canards and RSS
but the LCA has only RSS
So on that note, The Griphen might have some what of minor advantage
Byt not enough to justify it 20 million plus price increase
