F-35 Jet Fails in 65 Areas
F-35 Jet Fails to Meet Basic Operating Standards in 65 Areas – Pentagon Report

WASHINGTON (Sputnik) – The Lockheed Martin F-35 Joint Strike Fighter still suffers at least 65 basic deficiencies where it continues to fail to meet basic testing specifications, the Office of the Director, Operational Test and Evaluation (DOT&E) said in a report.
The JPO [F-35 Joint Project Office] completed the readiness review for JSE [joint simulation environment] trials in September 2023, and certified it as ready for testing, despite 65 deficiencies against the baseline JSE requirements, the report said on Friday.
The F-35 program development cycle continues to experience delays due to immature and deficient Block 4 mission systems software and avionics stability problems with the new Technology Refresh 3 (TR-3) hardware going into Lot 15 production aircraft, the report said.
“As a result, deliveries of production Lot 15 aircraft in the TR-3 configuration are on hold until more testing can be completed and the avionics issues resolved. …[T]hese delays prevented the F-35 JPO from adequately planning and programming for hardware modifications … of the upgraded hardware configuration,” the report said.
Also, the necessary flight test instrumentation, including both aircraft and open-air battle shaping instrumentation, for both, the remaining TR-2 configuration and upgraded TR-3 aircraft, are not all on contract and will not be available in time, the report added.
In June 2019, Defense News published an investigation into the F-35 that detailed all 13 category 1 deficiencies on the books at the time — the first and only time a full list of F-35 critical deficiencies has been publicly released.
Details of [deficiencies] — even unclassified [deficiencies] — are not publicly releasable; but here is a list of known problems:
- A technical problem involving the F-35′s cockpit pressure regulation system led to several incidents of extreme sinus pain, or barotrauma. In April 2020, the program office believed it would be able to resolve the problem in 2021 after flight testing the fix.
- On nights with little ambient light, the night vision camera embedded in the F-35 helmet could display horizontal green lines that could make it more difficult for pilots to land on ships. The JPO had intended to test a software update for the Generation III helmet to assess whether that could correct the issue with the hopes of declaring the deficiency solved in 2021.
- The F-35′s Northrop Grumman-made AN/APG-81 active electronically scanned array radar meets requirements, but the Navy wants to upgrade the system so that it can scan a wider area while in sea-search mode. In 2020, the program office stated that this issue would remain on the books until 2024, when a software update is made to the aircraft’s avionics equipment.
