Full article up now. No surprise that LM would prefer to sell the F-16; its a considerably more lucrative proposition for them than the F-35, with the margins for the latter being quite narrow.

From Business Standard. Full article's not up on Broadsword yet. Capability jump: IAF looks to buy fifth-generation F-35 fighter It is learnt the IAF wants to procure 126 of the variant called F-35A - the air force version of the fighter that incorporates "conventional take-off and landing"...

There seems to be a confusion with regard to legal terminology here, so lets clarify a few things here. An FIR i.e. a First Information Report is exactly what it sounds like - an information report. Basically a statement taken by the police. The police is legally required to file an FIR and, as per ...

Has the F 35 ever been in consideration for the IAF ? ..all the news i see is the contrary . LM is interested only in getting some quick buck for an obsolete line quite unlike Boeing which is going to great lengths to pick up partners and work with the indian industry even before a possible success...

Dipanker, Fernand Braudel in his three volume study on civilization and capitalism writes in his third volume that India is like a pendulum that swings westward or east ward.

The point is we operate 7 IL-78s being upgraded like all 16+ 76s with new fuel-efficient engines, glass cockpits, extra range and payload, etc.apart from the AWACS platforms.For commonality and cost effectiveness it makes sense to buy more of a type in service.If it was a brand new type/acquisition...

The data available on the RFI says that 2 engines only, but did it say that only 2 man crew without operator? I will have to bow out of this bizarre semantic jugglery where one has to interpret that what has not been said can be cited as a requirement on the basis of the argument that a boom operat...

By this logic air refuelling is unnecessary. But given the difference in (unrefuelled) radius of action of Tejas - say 350-500 km and Su-30 (1500 km) the Tejas would require more refuelling than the Su-30 in a mixed aircraft sortie. Yes - but other than P-8s which belong to the navy ALL other aircr...

Once the costs are found out, enormous operating costs too, with the bird conservatively priced at at least $135M, still not fully fit to fight, it will "crash "over here.My take is pressure upon both Dassault and the Russians to bring down their offers for more birds and the FGFA to some...

Most small aircraft are unable to take the high rate of flow offered by the boom system - one more useless redundant feature waiting for those 20 odd aircraft for their 1 in 100 flight need to refuel midair. And if the boom is used with a basket to attach to a probe - the imagined advantage of fast...

Viv S

Fact. Those 22 aircraft will not need air refuelling for 99% of their airframe lives in their service in India. While our existing fighters - 280 odd Su-30s, 40 odd Mirages right now can do with refuelling and projected, already ordered numbers of Tejas will need that more than ever. I a A fighter ...

I haven't seen any evidence that C-17 or P-8I have come ready for Boom refuelling. Without Boom tankers (present or on order) I doubt India would have paid for these. Moreover our pilots would not have been qualified for such and they wouldn't have been able to test the system while accepting the a...

Viv S

You are implying: "IAI's Target market==must have for IAF" I'm saying 22 of the largest aircraft in the IAF & IN fleets are designed for boom-receptacle refuelling, with an additional 12 that are capable of it. Numbers that will continue to grow over the next 40 years. And I'm saying ...

Viv S

Having it and not needing it would be a ludicrous waste like a man buying tampons for himself.That probe on the C-130J would be as much a waste as a 100% useless boom waiting for a call from the Indian navy for refuelling a P8I The C-17 on international (long range) deployments would be able to emp...

Viv S

You mean a hose/basket will get attached to the end of a boom for the C-130. I'll believe that if and when I see a flying boom tanker in the IAF so I think it is simply speculation. Hose-drogue under the wings & fuselage. Boom under the tail. Hardly a complicated setup. IAF C-130s have a probe ...

Viv S

So C-130Js can be refuelled using either? Yeah. Probe and drogue and flying boom are different systems. Boom is rigid and gives high flow rates - but only 1 a/c can be refuelled at at a time. Probe and drogue is a hose, lower flow rate, can feed multiple aircraft and can be adapted for buddy-buddy ...

Viv S

Kartik, as you sure that C-17 and P-8I require boom refuelling and are not compatible with Midas tankers? Do you have a link? He's right. Both the C-17 & P-8I are equipped with boom-and-receptacle refueling systems (you can see the symbology above the cockpit). There's no record of either being...

While the F-16 is a dead-end (the Rafale is a better option in the same 10 ton range), the IAF may finally be cottoning onto what will be the global standard for the next 30-40 years. I wouldn't be surprised at all if this is to be the IAF's next SEF - IAF mulls F-35 order Early stage deliberations ...

The singapore deal for 6 Airbus mrtt itself was north of $3bn. You want MoF to sanction double that amount for $12bn? Fast chance. That we've selected the Airbus and cancelled twice is typical. Same as the hawk and other deals. The Airbus isn't in serious reckoning for the contract. This is between...

The IAF issued an RFI for 600 7.62 mm rifles in May last year, presumably for the Garuds.

Anyone know whether this was for an assault rifle (7.62 x 39) or battle rifle (7.62 x 51)?

The IN seems to have a strategy in place. If and when a need is identified to supplement P-8's with anything manned, I'm sure local industry can built something around a proven, reliable and operational platform. The C295 sounds like a really good option considering it will be locally built. With a...

There seems to be an odd sort of dichotomy in many of the arguments here - unanimity over the idea that India's ME policy ought to be shaped by national self-interest being used to justify a course of action that would support Israel's interests while, at best, being only neutral to India's interest...

Yes, the Mig-21 could do it. But it could also reach Mach 2 without them. LCA/Gripen don't have that level of margin. Reaching Mach 2 was more a function of the design rather than the thrust-to-weight ratio. Ultimately, what matters is adequate excess thrust to cover the drag added by the tanks (pl...

Actually most aircraft are integrated with a set of supersonic as well as subsonic tanks. Eg. - The Mirage on the right cannot go supersonic without losing the two subsonic tanks. Are these supersonic tanks? I don't think so. That's kind of the point. I posted pics of two aircraft types. One exampl...

But if the purpose is urgency anything hanging off the aircraft is a liability. Most pictures I have seen of CAP by western fighters feature drop tanks. But none are doing CAP at supersonic speeds. They probably empty those tanks first and if at all a supersonic dash is needed they would jettison t...

Viv S

I accept this as a valid possibility but as I said in my first post a high speed dash would require a rapid climb to altitude where supersonic would help get closer to target. But those tanks would reduce both climb rate and acceleration. There may be a "sweet spot" where a single drop ta...

I request people not to tell me that it will allow Tejas to fly supersonic with drop tanks.

There is no protocol outside of link-16 when it comes to the standard and nature of the data that would be shared on the F-35.

That is what I have been saying they wont allow F-35 to integrate with ODL they dont intent to share F-35 data. If UAE and Turkey wants they can have their own data link but that wont change the intent of US to share the data with 3rd party system. The F-35 data is no different from the F-16 data a...

There is no gurantee that US would allow integration of F-35 into any other assest , considering it is not allowing NATO allay Turkey to integrate with S-400 or close allay like UAE to allow it to integrate with Su-35 ......certainly US officials have mentioned that officially now so all bets are o...
