The Army programme is going well, with the first CH-47F delivered in 2005. But one significant change has been made. Due to the costs involved in refurbishing the existing aircraft's airframes, it was found to be more cost effective to build new, more durable, composite airframes. This is not really surprising since these helicopters have been rebuilt more than once (from A models to D models) and in some cases are 40 years old or more. The Army anticipates flying these rebuilt (again) aircraft until 2030, giving many of them a total service life of 70 plus years.
