To try and get around software-associated delays, the F35 test program is being revised: some test points are being eliminated, reducing the total number of test points remaining for Block 2B from 529 down to 243; and some fixes are being deferred to the Block 3 program. A major operational test series planned for the Lockheed Martin F-35 Joint Strike Fighter has been abandoned in an attempt to protect the schedule for delivering a fully operational aircraft. Previously reported improvement in reliability was due to changes in how failures were reported. The Pentagon’s Director of Operational Test and Evaluation also notes that an apparent improvement in a major reliability metric - "mean flight hours between failure - design controllable" - up to late summer 2014 may be due to changes in reporting.
In 2009, Boeing had an idea. Instead of developing an entirely new fighter for a market already dominated by the F-35 Joint Strike Fighter, it would update an already existing fighter with the latest in technology. Even better, it would be low observable—a step below stealthy planes such the F-35…
Full stealth jets like the F-22A Raptor create drastic reductions in radar detection range. The Su-35S will have IRST (infra-red search and track) system to enable detection of stealth fighters like the F-22A. The F-22A will be able to spot the more detectable Su-35s at larger distances. The SU-30…
