There are countless technical problems encountered during the development of the Joint Strike Fighter, ie the fighter said 5th generation F-35 Lightning II, launched in 2001 and led by Lockheed Martin.
And the reports are very similar. The latest, written by the office of operational test and evaluation (DOT & E) Pentagon has even questioned the ability of this device, which comes in three versions (Classic, naval and STOVL) to be fully operational on schedule. Moreover, these development problems caused by the complexity of this plane, accompanied by skyrocketing costs. And it seems that every problem causes another set in elsewhere.
Such is the case of the active antenna radar AN / APG-81, F-35, supplied by Northrop Grumman: its function is impaired by a "bug" of the operating system of the device software with over 8 million lines of code. The problem came with the 3i version of this program, meant to give the F-35 close to 90% of its operational capacity. Thus, the radar locks and the driver is obliged to turn it off and on again for it to work again.
However, Lockheed-Martin, who said he identified the cause of the bug fixes must deliver in the course of this month, which would allow the US Air Force declared initial capability of its F-35 to 'summer. "Some systems such as radar control are fundamentally worse than the previous version, which is not a good sign," said Keith Joiner, former head of the Evaluation of the F-35 in Australia, reports The Guardian. "The next version of the software will not be available before 2020. So there will be nothing other than fixing bugs in the current software by then," he noted. But Keith Joiner is very critical of the way is conducted in Australia, the development of the F-35.
In January, in a document addressed to the Australian Parliament, he had regretted the agreement given to Canberra for the start of production of devices for the Royal Australian Air Force (RAAF), while the development of this aircraft is not yet complete. "Stop being naive: this is not because something should work it will work," he shouted to parliamentarians.
