Certainly the joint strike fighter office provided 36 years' worth of sustainment cost information. The life-cycle costing policy requires identification of the costs over the full life cycle.
You'll notice that National Defence's policy, as I read it, even refers to the cost of disposal. By definition, if you have to include the cost of disposal, the expectation would be that you have to go out to the full life of the particular asset.
That was something we identified. We felt that life-cycle cost information should have been for that full life cycle of the aircraft, rather than just for 20 years.
