The F-102 Delta Dagger was used by only two foreign air forces, those of Greece and Turkey.
Beginning in 1968, approximately fifty F-102As and TF-102As were transferred to Turkey from USAF stocks. Before transfer to Turkey, they were overhauled by CASA in Seville. They were initially assigned to the 191st Filo (Squadron) based at Murted, replacing the F-84F Thunderstreaks previously assigned to this unit. This unit was redesignated 142nd Filo in early 1973. In 1971, F-102s were also assigned to the 182nd Filo based at Diyarbakir, replacing the F-84Fs previously being flown by this unit. F-102s remained in service with these two squadrons until mid-1979, when they were replaced by the F-104G in the 142nd Filo and by the F-100C in the 182nd Filo. A couple of Turkish F-102As are reported to have been shot down by Greek F-5As in mid-1974 when Greece and Turkey clashed over Cyprus. One kill was by a AIM-9B Sidewinder, the other was by cannon fire.
In light of the supply of Delta Daggers to Turkey, it probably comes as no surprise that F-102As and TF-102As were also transferred to Greece. In 1969, Greece acquired 24 of these aircraft for use by the 114 Pterix (Wing) at Tanagra. 19 of them were single-seat F-102As, five were two-seat F-102Bs. They served with the Greek air force until 1978, when the F-102s were replaced by Mirage F1CG fighters.
