Prastitye pazhalusta, ya iz Indii; ya ni gavaryoo paruskii! :)

For strategic purposes, Mil-26T2 is better, because it is faster , has a longer range, and can carry almost twice the number of troops (90) than the Chinook (assuming there are no spare problems).
It depends which variants of Chinook we are talking about .
The UK's Chinook has maximum speed of 295 km/h (183 mph) .

IAF's heavy-lift helicopter tender opened

IAF's heavy-lift helicopter tender opened
The defence ministry has opened the bids of the two contestants in Indian Air Force (IAF) competition for heavy-lift helicopters and a decision would soon be taken on the winner based on the life-cycle costs.

Highly placed sources told India Strategic defence magazine (..:: India Strategic ::.. Home Page: The authoritative monthly on Defence and Strategic Affairs.) that both the Russian Mi-26 and the Boeing Chinook Ch47F had qualified in the technical trials and that their financial bids, covering the initial acquisition cost as well as the lifecycle costs, were opened September-end.

The bids were opened in the presence of their representatives, and the winner would be declared based on what is known as the L-1, or the lowest bidder principle. The IAF is looking for 15 heavy-lift helicopters.

Sources said that a decision should take about a couple of months or so, unless one of the vendors has given incomplete replies for which clarifications would be required and that would add to the time needed. "Absence of replies or incomplete replies do happen, leading later to interpretation issues and disputes; so it is best to sort them out right in the beginning," the sources said.

They also said that discussions with the French manufacturer Dassault for finalising the contract for 126 Rafale medium multi-role combat aircraft (MMRCA) were being held on almost a daily basis and the contract should be finalised and signed by the end of fiscal 2012-13, that is by March 2013.

Representatives of Dassault, which makes and integrates the aircraft, and Thales and Safran (Snecma), the two companies which make the electronic warfare systems and engines respectively, have also been visiting New Delhi and Bangalore regularly for negotiations with IAF, defence ministry and Hindustan Aeronautics Limited, the lead Indian integrator. The option clause for 63 more MMRCAs would be worked out in due course of time as the negotiations progress.

Interestingly, all the aircraft deals with Russia so far have been on single-vendor, government-to-government basis, and to get a favourable decision in the case of heavy lift competition, the Russians will also have to fulfil the obligatory 30 percent offsets requirement, besides being lower in the costing. If they win, this will be the first aircraft offsets case for them.

The IAF has been using the Mi-26 helicopters for about a quarter century now, but they are outdated in technology, consume too much fuel, are expensive to maintain and their spares also are not easily available. Russia will have to produce newer units with refined technologies anyway for their own or global sales.

Lockheed Martin and Boeing of the US have won orders for 12 C-130J Super Hercules and 10 C-17 Globemaster III aircraft and in both these deals, there is a 30 perrcent offsets clause.

The suppliers are given three years to deliver the first units after a contract is signed.

If i am not wrong then Weight of one of lightest artillery i.e. M777 howitzer is more than 4 ton and maximum weight carrying capacity of Chinook is less than 4 ton. Then what's the use of it if it can't carry such a important asset in battlefield?

Found something interesting on the Mi series and Mi-26 doesn't look good :rolleyes:





Under utilisation is also evident from the maintenance schedule as the four Heavy Lift helicopters had completed only 66 per cent of their prescribed TBO of 900 flying hours when the airframes had to be sent abroad for overhaul at a cost of USD 15.64 million (Rs 70 crore) since they had completed a calendar life of eight years from the last overhaul.

Re: IAF's heavy-lift helicopter tender opened

You believe it is a far better choice than Mi-26?
The only reason is that the Chinook is more up to date and advanced as compared to Mi-26. Helicopters are very important assets, no need to compromise on technology just to satisfy somebody's ego.

If Mi-26 is as advanced and up to date as the Chinook, then it can be anybody's win. But I doubt it is so because Russia has not spent a lot on their helicopters.

Apart from electronics the Chinook has a higher flight ceiling and a more powerful engine for it's weight class. It's design allows it to perform better over mountains.

Mil-26T2 is up to date and at par, at least on paper, but with a single rotor, it could never match the stability of the CH47F.

Between these two, the way I see it, CH47F will make a better tactical helicopter, and Mil-26T2, a better strategic helicopter, over the other.

This is assuming there is no shortage of spares from Russia and no embargos from USA.

I don't know by how much. For eg: The difference between Mi-28 and AH-64 was only 20 points, but IAF chose AH-64 nevertheless even with an assumed cost advantage in favour of the Russians.

Both helicopters have their advantages, but the electronics advantage may push it to Chinook in favour.

May the best helicopter win.

Very low chances for the former. Very high chances for the latter.

Chinook is more like a tactical heavy lift helicopter

While Mi-26 is a stratigic heavy lift helicopter, both serves specific purpose and so they have been designed, while selecting the winner it will depend upon the needs of the end user as for what purpose the helicopter is needed and will be used but if it is raw lift capabilities ....
