"The Pentagon has notified Capitol Hill of an updated “concurrency” cost estimate for F-35 low rate initial production (LRIP) lots 1-12 that has declined by 2% compared with the previous year’s evaluation, to $1.41 billion, because of fewer “forecasted issues.”

With the completion of development testing, issues forecast to emerge from flight testing declined from $150 million in the 2017 cost estimate to $30 million in the 2018 prediction, Pentagon acquisition executive Ellen Lord writes in a July 5 Joint Strike Fighter concurrency cost report. The report complies with the 2012 Military Construction and Veterans Affairs and Related Agencies Appropriations Act. Aerospace DAILY viewed a copy of the report.

The Defense Department defines concurrency as an overlap in the development and production phases of an acquisition program. This requires modifications to early production lots because of deficiencies discovered during qualification, ground and flight tests, or because of new engineering analysis.

“Incorporation of concurrency design changes adds cost because of recurring engineering activities, production cut-in, and retrofit of existing aircraft,” the report says. “These costs do not include the nonrecurring engineering costs incurred to develop engineering solutions associated with these changes.”

Planned and scheduled block upgrades to each aircraft are handled separately and are not considered concurrency costs by the Pentagon. For any LRIP lot there are potentially three types of concurrency changes: items discovered before beginning production of the lot; changes during the period of performance of any given lot; and things discovered following delivery of the last aircraft in a given lot.

“Retrofit activities to incorporate changes into operational aircraft compose the major portion of concurrency costs,” the report reads. “Examples of retrofits that have been performed include the F-35B Auxiliary Air Inlet Door Assembly, the F-35B Fuselage Station 496 Bulkhead modification, and Forward Root Rib modification for the F-35A and F-35B.”

Wonder how much the Coronavirus pandemic will effect costs (and not just with the F-35 Lightning II)
