There is also a time when you have to start worrying about things like air frame, engines. This helicopter is 40 years old. Helicopters are just not designed for that kind of service life even with upgrades especially military ones which are work horses. If the air force wants a heavy lift cargo aircraft for carrying out operations like stealing that Egyptian radar in 1969 then prehaps a couple of Chinooks and other aircraft for troop transport. If they want something more multi role then its another issue because as far as I know the CH-53 is not built anymore. Another possible option is look to Europe. I know European hardware cannot be paid for with military aid but the IAF need to decide do they want whats best for the job or whats cheapest. They should remeber though that whatever they buy is going to be in service decades so its a one off purchase and the current CH-53 eventually have to be replaced it can't be put off forever so the IAF need to start thinking about the future... can buy a whole fleet of helicopters for the price of 1 F35 jet which is not the plane the IAF needs anyway as its next generation fighter and its to expensive to ever replace the F16 as the multi role fighter of the future so if we do buy any of those things how about buying less and saving the money for things like helicopters.
