Lockheed Martin has received the first fixed-price contract for F-35 production aircraft. It took several months of negotiating to convert production orders from cost-plus to a fixed-price format two years early. Was it worth the wait? See the chart below (updated with corrected percentages in "change" column):
The pre-LRIP-4 data comes from the "selected acquisition report", dated 31 December 2009, on the F-35 program, which FlightGlobal obtained several months ago. No data on LRIP-1 is available. The chart also does not include costs for government furnished equipment, which includes engines.
Under the cost-plus contract format from the system development and demonstration (SDD) phase through the third lot of low rate initial production (LRIP-3), Lockheed's actual costs exceeded the initial target by 15-34%. Those costs were simply passed on to the government, rather than absorbed by the contractor.
The fixed-price format is supposed to mean that the contractor bears more of the risks for cost overruns. Details of the final agreement on LRIP-4, however, are still not available. We do know the new contract is not a "firm fixed-price" deal. That means a certain percentage of any cost overruns in LRIP-4 could be passed on to the customer.
