Derby er has 100+ range
If it is 120 then derby range 60
A recent report says derby has range of 60 km
So asked you

The range depends on altitude too. For I - Derby maxout range is 70-80km

For Derby ER it is 160 km similar to AIM 120D

Rafael brochure says Derby ER as 100+

But it is chosen above russian missile with range 130km that means it is better in terms of range and electronics .

From hereon we can only speculate if someone thinks it is 100 only so be it if someone thinks it is 140 or 120 all gud as long as IAF get the best.


What about Aesa radar ? Will FOC have it ?
Nope right now AESA is meant for mk1a onwards.

But once Tejas mk1 comes for upgrade by 2030-35 they'll be upgraded to mk1a standard or better .

Rafael doesn't list it as 100km+... it is just 100km.

When something is classified to be exceedingly more capable they will use the plus. If they just list it then what you see is what you get. I am not one to make things up, I always look to official sources first unless it is fake Chinese propaganda.

If he is truly privy to privileged information he wouldn't be spreading it around social media like a honeypot traitor.
Careful whom you call a traitor mister ! HVT is a respected test pilot.

So why is he blabbing about his work all over social media? When I was in the service I was not even allowed to post to social media accounts.

Where is a media account of an upcoming Mach 1.6 test?
evaluation of the Tejas' combat capability must consider its flying performance, its avionics and the weapon load it carries. At IOC, it already flies at Mach 1.6 (2,000 kmph); operates up to 15,000 metres (50,000 feet); and carries 3,500 kg of mission payload, including weapons and sensors. Its combat radius is 300-350 km, which would be extended next year through in-flight refuelling. By FOC next year, this performance would be enhanced

(tho it's a article by ajay shukla i think HVT is also related to Tejas PR team)

Btw has anyone seen the 725L centerline droptank on Tejas? Is this the one they are saying or any other new supersonic version is there in 725L ?


What would be the capacity of the under-wing supersonic droptank on Mig-21 shown below.
Supersonic center line drop tank will be 710 litre.
Mig21 drop tank was much smaller probably around 400 litre.

Also lca f404 is much more fuel efficient than mig21 engine. According to ex IAF chief dhanoa lca flies as efficiently at lower altitude as mig would only fly at high altitude.

Mig-21 centrral droptank is 490lt. Its can carry either 3×490lt or 2×800lt

Older subsonic tank on LSP4 (possibly 725lt one).

New supersonic at AeroIndia19 (710lt, may or maynot have increased after that)

Net payload was always 5300kg. That includes internal fuel.
I don't think so. That number is including 2400kg of fuel.
Nope internal fuel + previous declared payload will be 2400+ 3900 ton == 6300ton.

So 5300 ton is only max external payload. It was not publishes earlier because it's not practical for any mission. Lca can carry it but will become a slow turkey.

But idiots like saab publishe gripen c/d payload at 5ton+ and now lca is competing for export hence matching the broucher figure. Truth is that both lca and gripen c/d won't carry more than 4 ton in any practical mission. But saab still uses marketing tactics so here is the reply.
