Defense News: WASHINGTON — The F-35 program office plans to close out the joint strike fighter’s development phase this year and begin moving into modernization, but it could face an uphill battle, the Pentagon’s head of weapons testing warned in a report released Wednesday.
The F-35 Joint Program Office has known since 2016 that it likely wouldn’t be able to make its October 2017 goal post for wrapping up developmental test flights, instead estimating it would take until February or even May of this year to finish those tests and end the system development and demonstration, or SDD, phase.
That means initial operational test and evaluation, or IOT&E — the last milestone before full-rate production starts — won’t be able to begin until late 2018, Robert Behler, the Defense Department’s new director of operational test and evaluation, said in his office’s annual report.
