WASHINGTON, Feb 3 : 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. (UNI)
