Actually it can fire the Python V at near BVR ranges, which is ~20-25 km.

15 km would be the bubble of NEZ where any target is extremely vulnerable.

The Bison flown by Wing Cmdr Abhinandan got within visual range of the F-16 at which he fired the R-73E. So, never assume that WVR combat won't happen. If that were the case, Air Forces wouldn't expend so much money and effort into getting top of the line WVRAAMs integrated.

Tejas Mk1A is going to get the MAWS. Which will be ported over to the 40 Tejas Mk1s once development for the Mk1A is complete.

Importantly, even WITHOUT a MAWS, a pilot can be made aware of a missile launched at him..AEW&C and AWACS both have the capability to detect a missile launch and warn their fighters.

The JF-17 Block 1 and 2 don't have HMDS or PL-10. You guys don't even know WHICH HMDS will be used. And there is no roadmap for when these will be integrated, tested and then retrofitted on over 100 JF-17 Block 1 and 2s.

So in a visual range fight, the Tejas Mk1 is far more dangerous than the JF-17 Blk 1 and 2 since it can use the DASH HMDS and R-73E or Python V. JF-17 will use the older PL-5EII WVRAAM which is NOT a HOBS missile. It's off-bore capability is rather poor compared to the R-73E and not comparable to the ASRAAM or Python V.

Hi, no. Just no.

BVR range exceeds 37km. Not 20km to 25km. That's not near bvr. That's still wvr.

'The Bison flown by Wing Cmdr Abhinandan got within visual range of the F-16 at which he fired the R-73E. So, never assume that WVR combat won't happen. If that were the case, Air Forces wouldn't expend so much money and effort into getting top of the line WVRAAMs integrated. '

WVR combat didn't happen on the 27th of Feb. It was all bvr.

The r73e was unable to be fired as he was constantly being jammed so much so he had no idea where he was when he was shot down.

It's impossible for him to have fired his r73e in the first place when all missiles have been recovered. Plus he was engaged at more than 30km away which is the MAX range of the r73e.

Also aewac and awac are the same thing.

But the awacs can only be able to detect the launch if it's actually there. Looking at the small size of Indias awac fleet, I think it's safe to say it won't be able to cover most of the air ops launched by ur air force.

Just because we, as civillains, don't know which hmds will be used doesn't mean those actually making and flying the jet don't know either. They most certainly do.

Jf17blk1 doesn't really exist anymore. They are all blk2 standard. Plus pl10 would most likely be integrated since we are gonna be integrating aesa radars into our blk2 aircraft.

Also also just because you don't know about the roadmap doesn't mean it doesn't exist.

Looks like a Photoshopped image. What's the source?

Big news, though it's not from an official source, so take this news with some caution..however, it is true that the Tejas Mk1 has now undergone trials confirming it's potency in "very challenging" scenarios with Derby BVRAAM and Python V CCMs. This might convince the IAF to move No.45 'Flying Daggers' squadron to a base on the Western sector.

The news about the second No.18 'Flying Bullets' squadron being meant to replace No.51 'Sword Arms' squadron based at Srinagar AFS is interesting. Had read this earlier as well, that the IAF meant to replace the Bisons at Srinagar AFS with Tejas Mk1s.

Twitter link

The IAF will start deploying indigenously developed Tejas on the western front by mid this year frm their home base in Sulur. Tejas temporarily had deployed in the western front close to the Pak border last yr bt that not permanent. 2nd squadron at the home base in Sulur,
with more aircraft in the pipeline to be delivered in the next 2 months, the first squadron will move to the western front base to make space for the second squadron. FOC variant of the Second squadron is likely to be posted at Srinagar AF Base to replace the Mig-21 squadron.

Onboard Oxygen Generating System (OBOGS) being trialed on a Tejas Mk1 Prototype Vehicle..which means it most likely is intended for the Tejas Mk1A..




OBOGS plus air to air refueling will give a massive increase in the range and endurance of Tejas Mk1A fighters since they won't run short of liquid oxygen carried in cylinders in the fighter.

Tejas Mk1


I had seen this article earlier but forgot about it. Reading it once again somewhat convinced me that the latest Derby trials from the Tejas Mk1 off Goa coast were with the new I-Derby ER extended range BVRAAM. That's what the "enhanced capabilities" referred to in all the official press reports.

So "official sources" confirmed to Janes back in May 2019, that the IAF would be acquiring I-Derby-ER BVRAAMs from Israel to equip the Tejas Mk1s.

We may see this new missile equipping Su-30MKIs in the future, replacing the R-77 stocks that may be nearing their operational end of life.

IAF plans to arm it's Su-30MKI fleet with I-Derby ER BVRAAMs

The Indian Air Force (IAF) is planning to arm its fleet of Sukhoi Su-30MKI multirole fighters with the Rafael Advanced Defense Systems I-Derby ER (extended range) beyond-visual-range air-to-air missile (BVRAAM) once the service phases out its ageing Russian-made Vympel R-77 (AA-12 ‘Adder’) AAMs by 2021–22.

Official sources told Jane’s that the IAF is in talks with Rafael to acquire the active radar-guided I-Derby ER, which has a range of 100 km, adding that the procurement process for the missiles could be finalised “imminently”.

The latest developments come after the fire-and-forget I-Derby ER missile, which features a software-defined radar seeker and a dual-pulse solid rocket motor, was selected to be the primary AAM to arm the IAF’s indigenously designed Tejas Light Combat Aircraft (LCA) following successful test-firings in July 2018.


An earlier version of the Derby, which can be configured as a surface-to-air missile, is also part of the IAF’s 18 Spyder-SR air-defence systems acquired from Rafael in 2008–09 for an estimated USD1 billion.

Delivery of the Spyder-SR systems, which included 750 Derby missiles, began in 2012 and was completed three years later.

The Indian Navy was the first to integrate an older Derby variant onto its since-retired Sea Harrier FRS Mk 51 carrier-borne fighters from 2005–06.

Unlikely as the Astra is in serial production for the MiG series and Su(along with other fleets but others already have superb missiles)
The costs of integration(CFD studies, fee for Rafael/NIIP/Su Irkutsk, flight trials across envelopes, certification etc) may be prohibitive
Even for BraMos integration, costs were borne by HAL and still cost us >$10 Million (Russian demand at $200M:o:)


IIRC, for the Su+Ukranian R-77 vs Mirage+MICA, A2A tactics was to overwhelm to try and negate advantages of the Mirages(Pilots/quality of ICMS Mk-3,RDY-2,MICA etc) and exploit the Su advantages(Better awareness/endurance/loads)
Astra already handsomely out ranges any known solid fuel Active A2A missile with the IAF so not too bad in that domain.

Will still be great if a Meteor integration can happen though.(Dream-1, Reality-0 :-))

You never know about Meteor integration..I read somewhere that the UK is offering a JV with India for Meteor Mk2, on lines similar to their JV with Japan which puts an AESA seeker on a Meteor for the JASDF.


SP-26 on it's first flight! This is the 7th Tejas Mk1 FOC fighter..6 should have been handed over to the No.18 'Flying Bullets' squadron.

Seems IAF is holding off delivery of new jets as of now in view of current financial crunch. HAL is utilising this time to update all the software patch and new weapons integration right now which could have been done even after delivery.

DRDO Uttam AESA Fire Control Radar installed for testing on Hawker 800 commercial ac converted into a flying testbed with a modified nose. Half of recently ordered LCA MK1A will be fitted with Uttam AESA radar. Additionally 2 LCA ac are already flying with Uttam radar for tests

Image is probably scanned from a DRDO publication, would really like to see a HD image though.
Remembered the image thanks to Amit Kashyap's video
