I had contractor support for six of those MCDVs. While it's news to me that it's gone to hell, when I was there the support was superb. The company that we hired would fly its technicians all over the world to repair them.
I will acknowledge Ken's point. Certainly based on the Athabaskan, a 47-year-old destroyer, once you start hitting age 30, your maintenance costs go through the roof, as you can all imagine what it's like maintaining a 30-year-old car.
