Military Posture

Greece's Special Standing Committee on Armament Programmes approved a defence procurement package worth nearly €5 billion on 16 March. The centrepiece is Achilles Shield, a multi-layered national air defence system valued at approximately €3 billion. The architecture is built primarily around Israeli technology, including the Spyder short-range system, Barak MX medium-range interceptor, David's Sling SkyCeptor for upper-tier defence and the ELM-2084 radar. An Israeli-developed AI command and control layer designed to classify threats and assign interceptors automatically is in final technical negotiations. The system will replace ageing Russian-made S-300 and TOR-M1 units and incorporate sensors distributed across Aegean islands. First deployments are targeted for late 2026, with full operational capability expected before end of 2028.

The package also includes the upgrade of 38 F-16 Block 50 jets to the Viper configuration at roughly €1.1 billion, bringing the total Greek Viper fleet to 121 aircraft. Infrastructure works at Andravida Air Base will prepare for the future arrival of F-35 fighters. The programmes still require sign-off from KYSEA, Greece's top foreign and defence council, and final parliamentary ratification. Defence Minister Nikos Dendias announced the decision from London, where he is on an official visit.

The Pentagon confirmed on 13 March that the USS Tripoli amphibious assault ship and the 31st Marine Expeditionary Unit, approximately 2,500 Marines, are transiting toward the Middle East. Open source tracking confirmed the Tripoli passing through the South China Sea on 15 March. The group carries F-35B fighters and is expected to reach the operational area within ten days. It will join the Gerald R. Ford and Abraham Lincoln carrier strike groups already on station.

The UK faced parliamentary criticism on 16 March over the delayed deployment of the Type 45 destroyer HMS Dragon. The warship left Portsmouth on 10 March, more than a week after the 1 March drone strike on RAF Akrotiri. Conservative MP David Reed challenged Defence Secretary John Healey in the House of Commons, asking which minister chose not to act on the Royal Navy's earlier recommendation. Healey said the decision was taken on the same day the Chief of Defence Staff presented it as an option.

France has approximately half its major surface fleet deployed to the Eastern Mediterranean and surrounding waters. The Associated Press reported on 15 March that French assets in the region now include eight warships, two helicopter carriers and the nuclear carrier Charles de Gaulle with embarked Rafale fighters. Paris frames the deployment as defensive and tied to eventual post-war diplomacy.

The multinational buildup around Cyprus remained stable on 16 March. No new deployments were announced. Greek F-16s and frigates hold their positions near Cyprus. Türkiye's six F-16s at Ercan remain in place. British, German, Spanish, Italian and Dutch naval assets continue operating in Cypriot waters.

Maritime Security

No NATO ally has publicly committed to sending warships to the Strait of Hormuz. U.S. President Donald Trump told the Financial Times on 16 March that he had asked seven countries to help escort vessels and that some had agreed, without naming them. He warned that NATO faced a "very bad" future if members failed to assist.

The refusals were direct. Greece said on 16 March it has no plans to join any military operation in the strait. Government spokesman Pavlos Marinakis said Greece's role is limited to the EU's Operation Aspides in the Red Sea. "Under no circumstances do we intend to get involved in war," he said. Germany's Defence Minister Boris Pistorius said: "It is not our war. We did not start it." A German government spokesperson added: "This war has nothing to do with NATO." Spain's Defence Minister Margarita Robles said the objective must be for the war to end. Italy's Foreign Minister Antonio Tajani said he did not support expanding Red Sea missions to the strait. Ireland confirmed it would not be involved. The UK said it was working toward a "viable collective plan" to restore navigation but would not be drawn into the wider war. Trump responded with personal criticism of Prime Minister Keir Starmer.

Japan's Prime Minister Sanae Takaichi told parliament on 16 March that no decision had been made on dispatching escort ships. Australia's Transport Minister Catherine King said her government had not been asked and would not contribute. China called for a halt to hostilities without addressing Trump's request directly.

EU foreign ministers met in Brussels on 16 March. EU foreign policy chief Kaja Kallas said she would propose changing the Aspides mandate and held talks with UN Secretary-General António Guterres on unblocking the strait. She acknowledged, however, that the strait is outside NATO's area of action. A European diplomat told Euronews that a large European coalition to escort ships was not expected.

MSC Mediterranean Shipping Company's emergency fuel surcharges took effect on 16 March, covering all cargo departing the Mediterranean and Black Sea, including the Eastern Mediterranean, Greece and Türkiye, to the Red Sea, East Africa and the Indian subcontinent. The surcharges were first announced on 7 March and extended on 12 March until further notice.

Maritime war risk insurance premiums for the Eastern Mediterranean and approaches to the Suez Canal have risen sharply since the conflict began. Modern Diplomacy and S&P Global reported increases ranging from 200 to 1,200 percent depending on route and vessel type, reflecting direct spillover from the Hormuz closure and regional missile and drone activity.

Diplomacy

Israel has pulled back from planned direct talks with Lebanon. Haaretz reported on 16 March that a round of negotiations expected in Paris or Cyprus has been postponed after Israel withdrew from the process. On 15 March, Israeli Foreign Minister Gideon Sa'ar had denied that talks were being planned. France had offered to host ceasefire negotiations, with a draft proposal reportedly calling for Lebanese recognition of Israel in exchange for a limited IDF withdrawal. Lebanon accepted the French proposal as a basis for talks. The United States and Israel are still reviewing it. Jared Kushner, Trump's son-in-law, was expected to lead U.S. involvement in any talks, with Israeli Strategic Affairs Minister Ron Dermer heading the Israeli delegation.

EU foreign ministers used the 16 March Brussels session to address broader regional coordination. Kaja Kallas framed the Aspides mandate discussion as part of a wider EU effort to protect energy supply lines. Neither the United States nor Israel consulted European allies before launching the attack on Iran on 28 February. That gap continues to shape European reluctance to commit military assets to the Hormuz mission.

Cyprus announced that EU informal council meetings scheduled for April to June will resume in person, reversing disruptions that followed the 1 March drone strike on Akrotiri. The decision is a political signal from Nicosia that the island is projecting restored stability, even as it remains the forward hub for multinational military operations.

Energy and Infrastructure

The Strait of Hormuz closure has made the Southern Gas Corridor the only major overland route carrying non-Russian, non-Gulf gas into EU territory. Every cubic metre of Azerbaijani gas bound for Europe crosses Turkish soil through the TANAP pipeline before continuing via TAP through Greece and Albania to Italy.

Türkiye's exposure runs in both directions. The transit position carries strategic weight but also cost. Türkiye imports approximately 6 billion cubic metres of gas from Iran annually, roughly 13 percent of its supply. If that flow is suspended, a monthly shortfall of 500 to 600 million cubic metres would open up, according to a March 2026 analysis by TEPAV, an independent Ankara-based think tank. Underground storage and LNG purchases make a physical supply crisis manageable in the short term, but budget pressure is immediate. Türkiye's 2026 budget was built on a $65 oil price assumption. Brent crude stood above $105 on 16 March. TEPAV estimates every $10 rise in oil prices adds $4.5 to $5 billion to Türkiye's current account deficit.

TAP added 1.2 bcm of annual capacity in January 2026 and is targeting 20 bcm throughput by 2027. TANAP's phased expansion targets 31 bcm by 2026 and 60 bcm at full build-out. Germany's SEFE signed a 10-year supply contract for up to 1.5 bcm per year. However, upstream output has not kept pace. Most of Azerbaijan's export gas comes from a single field, Shah Deniz, operated by BP. The operator has not confirmed expanded production volumes. Neither SOCAR nor BOTAŞ has disclosed whether TANAP throughput has changed since the Hormuz closure. Q1 2026 flow data remains unreleased.

The Baku-Tbilisi-Ceyhan oil pipeline, which moved approximately 1.2 million barrels per day in 2024, terminates on the Mediterranean coast. With Hormuz shut, Ceyhan is one of the few Eastern Mediterranean oil export points not exposed to Gulf shipping risk.

Israel, Lebanon Front

Israel struck more than 200 targets in western and central Iran over the past 24 hours. Israeli military officials said operations are planned for at least three more weeks, with thousands of targets remaining. Iran said it had fired approximately 700 missiles and 3,600 drones at U.S. and Israeli targets since 28 February. Cluster warhead ballistic missiles struck central Israel on 15 March, causing at least three injuries in Tel Aviv.

In Lebanon, the WHO confirmed on 15 March that 12 health workers were killed in an Israeli strike on a primary healthcare centre in Burj Qalawiyah, Bint Jbeil district, on 14 March. Since 2 March, at least 31 Lebanese health professionals have been killed and 51 wounded. Hezbollah continued rocket and drone attacks on northern Israel on 15 March, targeting the Haifa area and Safed. Israeli ground forces expanded operations in southern Lebanon.

Israeli airstrikes on 15 March killed at least 12 Palestinians in Gaza, including two children, a pregnant woman and eight police officers. In the West Bank, Israeli soldiers killed four Palestinians, two young children and their parents, on the same day. The Israeli military said forces had "sensed danger" after a vehicle accelerated toward them.

***Casualty figures from Lebanon and Gaza are drawn from local health authorities and international agencies. Israeli military claims are attributed as stated. Iranian missile and drone statistics are based on Iranian state media. Independent verification of all figures remains incomplete.
