The $29 billion contract between Lockheed and the U.S. Marine Corps is under strain for the delivery of 200 CH-53K King Stallion helicopters. This is due to a shortage of specialized metal components. The key supplier for these parts went bankrupt two years ago and the Navy is still looking for an alternate company who will be able to provide the service. They have been given a budget of $139.5 million per helicopter, including development costs. This price is 20% higher than the original price in 2005, reports Bloomberg.
