Instead of 10 m chapati a 7-8m chapati with triangular aesa antenna array should be possible or 7 m rotodome with single aesa array like in C295 aew 5 m dia elta radar rotodome .

If 100 % serviceability can be maintained than 40 mig 29k are enough for both carriers as both have standard complement of 20 mig 29k each and both will be available for only 3.5 years of the 10 years till TEDBF is available.

The 111 nos NUH started at 56 nos with 28 options before it went upto 111nos . It will be reduced to the original number of 56 nos just as LHD requirement.reduced to 2 from 4 and additional Kamov 31 order reduced to 6 nos from 10 nos. The NUH will be used in limited number on ships as SAR as it has ...

The mig 29 with the IAF had a crash rate of 0.8 per 10000hr. The mig 29 k have airframe life of 4000 hr. If used for 150 hr /year per aircraft one crash every two years can be expected.
The course of action is each crash is investigated and corrective action taken.

I will be surprised if it is only for shore based purpose as CG chief has clearly said the Dhruv helicopter has new rotor blade folding mechanism and is capable and will operate from CG ships. It beat naval Panther in competitive tender on all aspect and the total order of 25=[16 + likely 9] will de...

My estimate is LUH must be 30%cheaper than Ka226. It will and should get all 384 nos order of IA and IAF combined.

sankum

They are getting the best tech economically possible.
Will also develop indigenous tech. Can't stop aero programs for lack of some critical tech.

sankum

F404/414 have long service life and we will be having 20% spare engine. A short period ban will have no effect. No need to worry. The planners would have already factored in the scenario.

Thanks, then latter it can go on Kalvari class. We will have two competing system. Best will win.

The world is moving towards Li ion tech and latest IN RFP is the proof. It is better if we incorporate the latest tech. IN has given two year time period in the RFP to develop the tech.

The advantage of US fighters is that in case of war with China and heavy attrition of IAF fighters take place then in service US fighters can be transferred to India which IAF pilots are trained to operate.
In practice we will be in US camp.

Then why have IN ordered 16 ASW Naval Dhruv and CG 16 mk3 Naval Dhruv?

Great Article. Cancel the tender and both IN and HAL should work together for 111 naval Dhruv .

Looks great! I'm glad they did not go for the MI17-type intakes which was shown in one model. This model largely follows the ALH lineage. . What is wrong with the Mi17 intakes? Mi 17 has closely placed engines while modern helicopters like ALH and IMRH have widely placed engines on side. I think in...

The model shows 4 *19 *70 mm pod = 4*282.5 kg=1130 kg external payload.
