F-35 Problems: Late IOTE, F-35A Gun Inaccurate, F-35B Tires, Threat Data, Cyber… « Breaking Defense - Defense industry news, analysis and commentary: "WASHINGTON: Perhaps the most damning thing a director of Operational Test and Evaluation can say about a weapon is that it is not “operationally suitable.”
Here’s what the new DOTE, Robert Behler, says about the F-35 Joint Strike fighter in his office’s latest annual report:
The operational suitability of the F-35 fleet remains below requirements and is dependent on work-arounds that would not meet Service expectations in combat situations (emphasis added). Over the previous year, most suitability metrics have remained nearly the same, or have moved only within narrow bands which are insufficient to characterize a change in performance.
Overall fleet-wide monthly availability rates remain around 50 percent, a condition that has existed with no significant improvement since October 2014, despite the increasing number of new aircraft. One notable trend is an increase in the percentage of the fleet that cannot fly while awaiting replacement parts – indicated by the Not Mission Capable due to Supply rate.
Reliability growth has stagnated. It is unlikely that the program will achieve the JSF ORD (Operational Requirements Document) threshold requirements at maturity for the majority of reliability metrics. Most notably, the program is not likely to achieve the Mean Flight Hours Between Critical Failures threshold without redesigning aircraft components (emphasis added)."
