On the FB-site of the F17-Wing, is mentioned the arrival of the first upgraded Sk60. It´s 60086 and it´s called Sk60AU.
I thought, that a couple of Sk60 (at least 5 or more) have been already upgraded under a contract with SAAB and are flying since last year. I believe, I remember a article in Combat Aircraft. The ultimate goal is to have 35(37?) Sk60 (MLU).
Is the Sk60AU a different upgrade-project?
