Tejas Mk2 (Medium Weight Fighter) - News and discussions

No. The MKI's range is 3000Km on internal fuel.

On internal fuel, the Mk2 will comfortably outrange Mig-29, F-16, LCA Mk1, Mig-21 etc, which have ranges between 1400 and 2100Km. It will match Rafale, Gripen E and SH in the 2300 to 2500Km class.

With 3 drop tanks, at about 4000Km, the Mk2 will comfortably outrange MKI by at least 1000Km.

Of course, we are hoping MKI gets some significant upgrades in fuel carried, like the Su-35, including drop tanks, which will increase MKI's range to 4500Km.

Mk2 will more than meet the IAF's requirement for a single engine 4th gen fighter.
What's the range of the Mk1a? And are you quoting combat radius figures above or ferry range?
 
A 2.9 meter ASRAAM is a better option. Two additional WVRAAMs won't hurt.

MICA would be a better option then. But then we have to consider whether that pylon will need an ejector rack or a rail launched system.

We need to wait for official confirmation.
 
What's the range of the Mk1a?

Mk1 is 1700Km. Mk1A is bound to be better if the weight has been reduced drastically even after the addition of new equipment. Anything above 1800Km is excellent for the design.

And are you quoting combat radius figures above or ferry range?

Basic range or ferry range. You fly from one point to another using up all your fuel. Combat radius would be 40% of all those figures I mentioned.

But if I'm not mistaken, one of the reason why the Mk1 is pilloried is coz of its lack of range. it's around 400 kms of combat radius. You're quoting something else.

They aim to complete the preliminary design by year end, then start on detailed design. Then first flight in 2023. Total 4 prototypes, every 8 months, thats around 2026-27 for Operational clearance if i am optimistic.

If successful, it will be a good option to replace Mig29, M2000 and remaining Jaguar fleet.
 
ADA has always been successful in developing a jet on paper. Simply very impressive details. But as usual don't expect them to deliver on the timeline they have promised. This is completely new platform don't expect 1st TD flight before 2023, even if MK2 shares majority of tech with MK1.

Combat radius changes a lot based on what factors have been considered. Payload, range, transit time, on-station time etc, everything changes the combat radius, so there's no point comparing different combat radii without knowing the flight and payload parameters.

For example, both LCA Mk1 and F-35 can have 200Km combat radius, but they will conveniently forget to tell you that the on-station time of the LCA was 1 hour while the F-35's was 2.5 hours. What this means is both jets fly 200Km away from base and they just circle around a place for a 1 hour and 2.5 hours resply. So combat radius here can become misleading.

The best comparative figure is basic range or ferry range because it's flown with full fuel in the most optimum flying conditions and only has point to point transit, just like a jetliner flying to its maximum range. Then you can extrapolate from there to get a proper apples to apples comparison for combat radius.

Ferry range is specific to the aircraft while combat radius is specific to the mission.

Since the technology is already ready, they only have to validate and test the airframe. For LCA Mk1, it took 3 to 5 years. So Mk2 will take much shorter time.
 
Biggest new thing with regard to hardpoints in my opinion, is the inclusion of wingtip points.

And with a Multi-Ejector Rail on the inner underwing missile hardpoint, you can get 10 missiles and 3 tanks in an A2A mission load (if both points under inlets carry missiles as an A2A load won't require any pods).

Both pointless, more WVR missiles were not needed, only adds more weight.
The tandem launcher is rather bad than good, because it means that the payload increase doesn't effect the external wingstation, which still seems to be limited to WVR missiles only. => so when ever the mid wing station is blocked by A2G weapons, there is still no station for BVR missiles.

Most interesting improvement for weapons seems to be the centerline station, which hopefully can use larger sized weapons, that would make a much bigger difference.

You missed the cropped delta design. :D
Yes you are right ...I saw it later when I was reading one of your comment on hard points...love this design .but only concern is funding and timelines.Govt should fund this project properly and avoid vested interest to slowdown the development.

The program has already been funded. DRDO is asking for 800Cr more I believe, so that's the only thing left.

IAF is fully backing the Mk2, so it's not an issue with vested interests. Rather 'vested interests' now favour Mk2.

The canards need to have a dihedral of at least 5* to be of any major benefit.

Is it too much of change to make it DSI with wing body blending and mid body wing instead of high ?

Seems like too much happening around the wing root.
Pardon my ignorance.

They are planning first flight in Dec 2023. Which means the aircraft will enter the engineering phase only next year.

So you can expect a full squadron only in 2030.

Falcon was right on the bet.
His assessment~ first flight not before the end of 2023

Yeah. Every time there is a delay by one year, the schedule gets pushed by a year.

They are talking about building prototypes from next year instead of this year, hence a year long delay. And this can repeat if necessary.
