Excerpt:

Sixteen of 168 planned flights were completed in fiscal 2009, the second year of flight testing, according to Michael Gilmore, the Pentagon’s director of weapons testing. The program calls for 5,000 sorties to prove the aircraft’s flying capabilities, electronics and software.

The development phase must now be extended by at least one year, to October 2015, according to Gilmore, the former head of the Congressional Budget Office’s defense unit.
