Wow, so they have finally integrated LGBs with LCA.

Is there a possibility that LCA-1 can be used as an AJT? Will it be able to get to the price point of Hawk if we strip it off enough?
Perhaps re-engine it with Kaveri in the future?

What is that little object on the left right intake. A white device thats attached to a round red base. It is there on almost all pictures.


Added later : Yes shiv ji it is on the right one. Thanks. Also in the following picture it does look like a camera. In which case I hope ADA releases some of that footage too.

You mean under the right (starboard) intake? That is where the cannon twin muzzle is supposed to be. I wonder if they have installed some camera or something there.

The potential of LCA with the GE F-404 to be used as a light supersonic trainer has always existed and discussed. It will be a competitor to the South Korean T-50, both in price and capability. But IAF has never shown any interest in a supersonic LIFT. In fact, ADA did not even fly the trainer for over 3 years between Jan'2011 and March of this year. However, since then there has been renewed interest and the prototype (PV-5) has flown 28 more sorties.

I don't know what will happen of the trainer version. Probably it will only be used as a type conversion trainer. :( But a yeh dil mange more.

LCA trainer with a Kaveri engine is a dream. I will distribute sweets on the street if it happens. But I don't think that they will be working on that engine for much longer (other than for AURA). They will migrate to the 115 kN engine soon.

The first set of pics with 500lb LGB as it seems, but not with the sometimes reported twin launchers so far. Does anybody have further infos on them or when further weapon trials might happen?

Any idea of the origins of the 500lb LGB being carried? The fins etc look rather huge, which might make it difficult to dual stack them.

Those are 500KG (or 1000 lb) bombs kitted out with laser guidance. The receivers at the business end of these will have serious "takleef" like the Pakis at Kargil.

My guess, the existing kit (Paveway II/III) from IAF inventory.

As per the FB Page it is PB-500 Bombs

^^ Looks like the Israeli Griffin guidance kit.

The Israeli bombs were specifically developed for Su-30MKI, MiG27 & MiG21 and probably MiG29K/UPG

Check the bomb here http://www.imi-israel.com/home/doc.aspx?mCatID=66597 with the bomb here http://www.bharat-rakshak.com/IAF/Histo ... Dacca.html

Curiously, no Litening pod and the bombs are not marked, so looks like carriage trials flight. In Iron Fist 2013, Tejas did drop LGBs.

Each Tejas inner wing pylon can carry two unguided HSLD bombs like the Jaguar shown here http://lh3.ggpht.com/-qKtynYtR_6k/UbhdP ... t-2013.jpg

Though not two guided bombs.

Lot of Jaguar learnings were put to use for Tejas in those early days.

Off topic here, but found these not so usual pictures of Jaguar IM carrying HSLD bombs. Jaguar IM don't have laser rangefinders, so interesting whether they use conventional bombsights http://data1.ibtimes.co.in/en/full/3088 ... -image.jpg

Even more interesting is Jaguar IM carrying BL755 Cluster Bombs http://media.defenceindustrydaily.com/i ... IAF_lg.jpg

and dropping them. The aircraft on the right is IM

As said by others, it seems to be the Israeli Griffin LGB kit that we have seen on 1000lb bombs on LCA earlier too. And yes, the kit seems to bee too big to allow a twin carriage, that's also why I asked too about infos on integration of a twin launcher, since the limited space at the midwing station might be a problem for the aims of using a twin launcher. But then the question is, if they wanted to use the twin launchers at the wings in the first place, or if a configuration like the Mirage 2000 use it at the centerline is the aim.

Definitely smaller than the 1000lb in this pic (left Paveway, right Griffin) :

I think BR has a painting of a cover image of an IAF 50 years book that shows Jags dropping BL 755 on a column of tanks. I recall having scanned that image (I have the booklet) and uploded to BR.

That aside there is also a video of Jags (Tilpat 1979) dropping them
http://www.youtube.com/watch?v=J0oegPHT ... aABJoSc-wg

The final explosion appears to be fake, and created for Rajiv Gandhi

Yes, of course. It was more meant to show that the early model matches what tsarkar is talking about how multiple 250kg/450kg bombs on a same rack will be carried on the LCA.

^^^ That configuration is no longer possible, because the mid wing pylons are not plumbed.

But they did wind tunnel tests on carrying two bombs in tandem on the mid wing pylon.

^^ Even if they were plumbed, the middle pylon has the capacity to carry only 800 kg, i.e. it is not capable of carrying a 1200 ltr drop tank. A smaller drop tank might be used, but that would require further development and testing.

Sir but don't you think that if there was no plan to use LCA with Kaveri even as a trainer, ADA would have discontinued the LCA with alternate engine program? Since ADA is still on the alternate engine program, it is reasonable to assume that Kaveri may be integrated with it in the future at least in the trainer version.

AFAIK the alternate engine program is for Mk2, i.e. using GE-414 instead of the GE-404. The Kaveri program has been been delinked from the Tejas program. They still wanted to test it on a prototype, but even that has started dying down. The latest that one hears is that a Mig-29 may be modified as a test-bed (great if it happens). The 115 kN engine program that GTRE has embarked, if successful, will make it into LCA Mk2 and AMCA. For the Mk2, they would be whenever the SPs start coming in for middle life engine upgrades. And for the AMCA, we might see them in the series produced models from the get go. The prototypes and SPs will have imported engines.

It would be great to see "max" bomb load configurations being carried by the LCAs!

  • 10 x 250kg bombs (2,500kg) -> 2 each on mid and inner wing pylons plus 2 on centreline
  • 6 x 450kg/1000lb bombs (2,700kg) -> 1 each on mid wing pylons; 2 each on inner wing pylons
  • 24 x 100kg bombs (2,400kg) -> 3 each on mid wing pylons; 6 each on inner wing pylons and centreline

Thanks Shiv, for taking the effort to archive that book. Also, good work by cybersurg who archived the video. Those documents give good insight into operations in that decade.

For guided bombs which is the standard today,the number of weapons that can be carried is far lower. LCA has realistically only 3 weapon stations for LGBs/PGMs, but LCA test pilot Suneet Krishna once stated to the Tarmark007 blog, that a tandem pylon would be integrated and that it was part of the FOC tasks. So the qestion now remains how they look like and for which hardpoints they are meant. I still think that it might be similar to Mirage 2000 and it's tandem pylons, maybe IAF will use even the same for the LCA and the upgraded Mirage. The only problem will remain, that the use of the midwingstations for bombs, makes LCA limited to IR missiles only, so very basic self protection, similar to the Jags.

Thomson CSF Agave could range too..wide array of modes.

Ranging is critical to all fighter radars, after all, what use is detection (bearing only), if it cant range.
