No it isn't "under development" at all lolol.
MEANWHILE to illustrate GKL's point..

“The [F-35] program is using test point data from older versions of software to sign off capability specifications and justify baseline test point deletions, even though the old data may no longer be representative of the latest version of Block 3F software.”
Britain’s 14 F-35Bs are all thought to be running Block 3F software of various sub-versions. Yet the all-singing, all-dancing jet still can’t talk to its guided air-to-ground bombs properly, even with the latest patches installed.
“For Block 3F, the pilot is now able to see what coordinates are sent to the bomb, but is still not able to see what coordinates are actually loaded in the bomb,” noted DOTE. “The [US] Services are assessing if this correction meets the requirements directed by the rules of engagement in specific areas of operation.”
Even more worryingly, trials identified that the AIM-120 AMRAAM missile, which the Royal Air Force and Royal Navy intend to use as the F-35B’s main air-to-air weapon, cannot currently be used to its full potential by the supersonic stealth jet. After six test firings in simulated combat scenarios, test pilots identified “key technical deficiencies in the ability of the F-35 to employ the AIM-120 weapons”.
And there's plenty more, read it and inwardly digest.
Having worked in civil aircraft production, you have specific production markers to meet then the customer pays some more etc etc.
If you were to lie or otherwise deceive the customer, that would be fraudulent ....
