Greece Clears €5 Billion Defence Package Including Achilles Shield Air Defence System
By Bosphorus News Defence Desk
Five Programmes, Nearly €5 Billion
Greece's Special Standing Committee on Armament Programmes and Contracts approved a defence procurement package worth nearly €5 billion on March 16, 2026. Defence Minister Nikos Dendias announced the decision from London, where he is on an official visit.
The package centres on five programmes spanning all three branches of the Hellenic Armed Forces. The largest is the Achilles Shield, a multi-layered national air defence system valued at approximately €3 billion. The second is the upgrade of 38 F-16 Block 50 fighter jets to the Viper configuration, at roughly €1.1 billion. The package also includes infrastructure works at Andravida Air Base to prepare for the future arrival of F-35 fighters, a five-year €240 million support contract for the C-27J Spartan transport fleet, and the modernisation of four MEKO-class frigates.
Committee approval clears the way for a decision by KYSEA, the Government Council for Foreign Affairs and Defence. The programmes would then return to parliament for final ratification before contracts are signed.
Achilles Shield: Architecture and Systems
Achilles Shield was formally announced by Prime Minister Kyriakos Mitsotakis in parliament in April 2025 and is the centrepiece of a broader 12-year, €25 billion defence modernisation plan running through 2036-37.
The system is designed as a five-layer integrated architecture covering anti-missile, anti-aircraft, anti-drone, anti-ship and anti-submarine roles across Greek territory, land and sea. It incorporates existing Patriot PAC-2 batteries and is built to replace ageing Russian-made systems including the S-300 PMU-1 and TOR-M1 units.
The procurement is built primarily around Israeli technology. The Spyder system, developed by Rafael Advanced Defense Systems and Israel Aerospace Industries, is intended to replace short-range Russian OSA-AK and TOR-M1 units. The Barak MX is expected to take over from legacy U.S.-supplied MIM-23 Hawk medium-range batteries. At the upper tier, the David's Sling SkyCeptor interceptor is slated to replace the S-300 batteries. The ELM-2084 radar will serve as the primary detection and tracking platform. Israel has agreed to at least 25 percent domestic Greek industry participation across the programme.
Greece is also integrating an Israeli-developed AI command and control layer into the architecture. The platform is designed to automatically detect, classify and select the appropriate interceptor against incoming threats without requiring prior human evaluation, with the objective of preserving costly missiles for high-value targets rather than deploying them against cheap drones. Negotiations on the AI component between Athens and Jerusalem are in a technical phase and described as close to completion.
The first wave of systems is targeted for deployment in 2026, with full operational capability expected before the end of 2028. The Achilles Shield will also incorporate sensors deployed across Aegean islands, consistent with Greece's stated doctrine of distributing coverage across the archipelago rather than concentrating it at fixed nodes.

38 Block 50s to Viper: A Unified Fleet of 121
The 38 F-16 Block 50 aircraft currently serve with the 341 "Velos" and 347 "Perseus" Squadrons at the 111th Combat Wing in Nea Anchialos. Their upgrade to the Viper standard brings the total Greek F-16 Viper fleet to 121 aircraft, joining the 83 Block 52+ jets already in the upgrade process. The modernisation includes the APG-83 AESA radar, a new mission computer, advanced avionics, electronic warfare systems and Link-16 data link integration, enabling real-time data exchange with Rafales, F-35s and FDI-class frigates. Greece's total modernised fighter inventory is being shaped around 121 Vipers, 24 Rafale F3R and more than 20 F-35As.
Patriot to Bulgaria, Frigates to Cyprus, Package to Parliament
The package comes as Greece's military posture has shifted markedly since the outbreak of the US-Israel-Iran war on 28 February. On March 6, following a formal Bulgarian request, KYSEA authorised the deployment of a Patriot battery to northern Greece for ballistic missile coverage of Bulgarian territory and the positioning of two F-16s for Bulgarian airspace surveillance. Greece has also deployed the FDI frigate Kimon and the MEKO frigate Psara to Cyprus under the Greece-Cyprus common defence doctrine.
Dendias described Achilles Shield in his ministerial briefing as the heart of Greece's modernised military and a system that will free naval vessels and fighter jets from permanent homeland defence duties for broader operational roles.
Multiple defence analyses, including reporting by Army Recognition and Greek City Times, have framed the programme as a direct response to Türkiye's development of indigenous ballistic missiles including the Tayfun and Bora, which have extended strike range into the Aegean. Greek officials have not used that framing publicly, describing the programme in terms of evolving regional threats and the lessons of recent Middle Eastern conflicts.
