F35 is in production at Ft Worth and stands up with the USMC in 2012. The first UK pilots start training next year.
I don't know where you pulled that from
Bismark but the F-35 is a looong way yet from real production of proven and tested design aircraft. Development testing still has some five years to run. Churning out unproven airframes is not "production" in my book.
According to the US GAO -
Manufacturing JSF test aircraft continues to take more time, money, and effort than budgeted. By December 2009, only 4 of 13 test aircraft had been delivered and total labor hours to build the aircraft had increased more than 50 percent above earlier estimates. Late deliveries hamper the development flight test program and affect work on production aircraft, even as plans proceed to significantly ramp-up annual procurement rates. Some improvement is noted, but continuing manufacturing inefficiencies, parts problems, and engineering technical changes indicate that design and production processes may lack the maturity needed to efficiently produce aircraft at planned rates. Although DOD's restructuring actions should help, there is still substantial overlap of development, test, and production activities while DOD continues to push ahead and invest in large quantities of production aircraft before variant designs are proven and system performance verified. Given the extended development time and reduced near term procurement, DOD still intends to procure up to 307 aircraft at an estimated cost of $58.2 billion before completing development flight testing by the beginning of fiscal year 2015.
