There are two 'NULLO' QF-4 flights planned out of Tyndall AFB next week, the jets won't return, which suggests live warhead testing rather than just ballistic shots. That will leave just 3 QF-4's at Tyndall, these will then transfer to Holloman AFB (to join the 22 already there) for ultimate demise sometime during 2016, that will then be the end of the QF-4 drone programme.
