What changed · 6 Oct 2026

Tension held at the elevated level seen through early October, with no new escalation in the past 24 hours. Athens reaffirmed it will not seek Turkish authorisation for the stalled Great Sea Interconnector survey, while the Hellenic military reported an above-routine but not unusual day of Aegean airspace activity, including one interception of armed Turkish F-16s.

Military posture: 5/10 · Hellenic National Defence General Staff reported 7 Turkish aircraft (2 armed F-16s, 1 ATR-72, 4 UAVs) active in the Athens FIR on 5 Oct, with 9 national-airspace violations and one interception by Greek fighters; no new naval incident reported.
Diplomatic / political: 5/10 · Greek FM Gerapetritis called it "inconceivable" that Turkey could block Cyprus-Crete cable surveys, rejecting Ankara's coordination demand as implicit recognition of Turkish continental-shelf claims (reported 5 Oct).
Economic / informational: 5/10 · Great Sea Interconnector dispute remains at impasse: Athens says roughly 60% of seabed surveys are complete and work will resume once a NAVTEX request is filed, while Turkey's Defence Ministry (statement of 1 Oct, still operative) maintains no unauthorised activity will be permitted on its claimed shelf.
EW / SIGINT: 3/10 · No GNSS jamming, spoofing or other interference incidents plausibly linked to Greece, Cyprus or Türkiye were reported in the past 24 hours.
