Turkey only had F-5A, RF-5A & F-5B in service, no E!
1st batch of 19 F-5A & 2 F-5B was delivered in mid january 1966
20 RF-5A were delivered in 1969 & 1970
After retirement in the KLU, Turkey gets 44 NF-5A & 16 NF-5B from the Netherlands (from 1989 on).
48 F-5 (20 Northrop F-5A, 8 Northrop F-5B, 14 Canadair NF-5A, 6 Canadair NF-5B) were upgraded between 2001 & 2006 to F-5A 2000
The fighters were forseen to retired from Service in July 2017.
But not sure. I guess @sukhoy34 will know it exactly, he´s from Turkey. ;-)
