Despite 276 combat performance problems the Pentagon is trying to rush the F-35 to initial operational testing
by noreply@blogger.com (brian wang) from NextBigFuture.com on (#28SWV)
The US Office of Operational Testing and Evaluation released a 62 page report on the F-35 stealth fighter and still finds 276 deficiencies in combat performance.
Despite the problems a military program whose cost has soared from $233 billion to an estimated $379 billion has pilots and generals who will vouch for it. Recent estimates suggest the F-35 program could exceed $1 trillion over 50 years. The F35 is getting over $10 billion per year. Does money buy friends and support ?
The Joint Strike Fighter (JSF) Program Office (JPO) acknowledged in 2016 that schedule pressure exists for completing System Development and Demonstration (SDD) and starting Initial Operational Test and Evaluation (IOT and E) by August 2017, the planned date in JPO's Integrated Master Schedule. In an effort to stay on schedule, JPO plans to reduce or truncate planned developmental testing (DT) in an effort to minimize delays and close out SDD as soon as possible. However, even with this risky, schedule-driven approach, multiple problems and delays make it clear that the program will not be able to start IOT and E with full combat capability until late CY18 or early CY19, at the soonest.
* weapons problems
* software problems
* heat and overheating problems
* Vertical oscillations during F-35C catapult launches were reported by pilots as excessive, violent, and therefore a safety concern during this critical phase of flight. The program is still investigating alternatives to address this deficiency, which makes a solution in time for IOT and E and Navy fielding unlikely
* Excessive and premature wear on the hook point of the arresting gear on the F-35A, occuring as soon as after only one use, has caused the program to consider developing a more robust redesign.
* The Services have designated 276 deficiencies in combat performance as "critical to correct" in Block 3F, but less than half of the critical deficiencies were addressed with attempted corrections in 3FR6. [aka they are only even attempting to try to fix half of the critical problems in this current round of fixes]
* Significant, well-documented deficiencies; for hundreds of these, the program has no plan to adequately fix and verify with flight test within SDD; although it is common for programs to have unresolved deficiencies after development, the program must assess and mitigate the cumulative effects of these remaining deficiencies on F-35 effectiveness and suitability prior to finalizing and fielding Block 3F
* Overall ineffective operational performance with multiple key Block 3F capabilities delivered to date
Available only about half the time
* Continued low aircraft availability and no indications of significant improvement
2.5 times more maintenance needed than the permitted amount
On the positive side, they believe they have fixed the ejections seat so that they are now pretty confident it will not kill or seriously injure lighter pilots who eject. Pretty confident but not enough to change the rule that prevents lighter pilots from flying the F35. Modifications to the pilot escape system (lighter helmet, delayed parachute deployment for lighter pilots) were needed after testing in CY15 showed that the risk of serious injury or death is greater for lighter-weight pilots. Because of the risk, the Services decided to restrict pilots weighing less than 136 pounds from flying the F-35. The Air Force may be able to reopen F-35 pilot training to lighter-weight pilots (i.e., below 136 pounds) in early 2018. DOT and E is not aware of the plans for the Marine Corps and the U.S. Navy to open F-35 pilot training to the lighter-weight pilots
