THE SYSTEM EXPLAINED
FDI HN: the combat system, not just the hull
The published Greek baseline links surveillance, command and several weapon families.
SEA FIRE → SETIS
Radar and combat management turn observations into a managed tactical picture.
AIR DEFENSE
32 Aster positions in the published baseline; RAM provides a separate inner defensive layer.
SURFACE WARFARE
Eight Exocet MM40 B3C missiles and a 76mm gun in the manufacturer’s baseline.
UNDERWATER WARFARE
Hull and variable-depth sonar, MU90 torpedoes, helicopter and CANTO countermeasures form different parts of the chain.
Published FDI HN baseline, Naval Group, 24 March 2022. Fit and acceptance must be checked by ship. No national fleet-wide readiness claim.
Naval SPIKE: guidance, control and the Greek milestone
Rafael’s 2024 Naval SPIKE NLOS brochure gives a 32km maritime range and describes electro-optical guidance, mid-flight updates and an abort capability. Its sixth-generation feature set includes control handover and image-based target acquisition. These are product-generation claims; Greece’s exact accepted configuration must be established separately rather than borrowing specifications from a later helicopter variant.
The Hellenic Navy records acceptance firings on 21 October 2026, published 23 October, involving SPIKE NLOS and ER from a Machitis-class gunboat and a Mark V craft. That is a concrete progression beyond the 2023 contract signature; it does not establish every installation’s readiness or the size of the available missile inventory.

DEFENSE INDUSTRY GR / THE ANALYSIS
Naval Renewal: FDI, FREMM, MEKO & Submarines
SYSTEMS / CAPABILITY / EXTENSIBILITY
Programme reference: what is inside
| Element | Function and Greek relevance |
|---|---|
| FDI HN: manufacturer baseline | Approximately 4,500 tonnes, 122m long, 27-knot maximum speed; aviation facilities for a 10-tonne-class helicopter and VTOL UAV. |
| FDI weapons | Naval Group lists 32 Aster missiles, eight Exocet MM40 B3C, RAM, a 76mm gun, four torpedo tubes, MU90 and CANTO countermeasures. |
| FDI sensing and management | Sea Fire radar; Janes identifies Kingklip Mk2 hull sonar, CAPTAS-4 Compact variable-depth sonar and SETIS combat management. |
| FREMM / MEKO / Type 214 | Different fleets and upgrade lines: planned Italian ship transfers, MEKO package awards and submarine mid-life industrial arrangements must be tracked separately. |
What the capability changes
FDI combines surveillance and area air defense with anti-submarine and surface missions. The sonar, helicopter, torpedo and command-system chain matters as much as the hull. Fleet improvement is net usable capability after retirements, maintenance periods and crew generation, not the gross count of incoming ships.
Extensibility and the next configuration
Future weapons or UAVs require physical interfaces, electrical and cooling margins, combat-system software and acceptance. An available space on a ship is not an approved integration. Additional FDI, FREMM transfer adaptations and MEKO upgrades can increase common capability, but may also widen the support catalogue. Configuration must be recorded by ship and date.
Integration and through-life support
Sustainment needs trained crews, shore engineering, spares, maintenance access, sonar and radar calibration, software support and munition recertification. Greek participation can include fabrication, platform equipment, inspection and support, only where an actual award identifies the role.
What remains unconfirmed
The 2022 published FDI baseline is not a claim that every ship has completed acceptance with every listed weapon. Italian transfer configuration, any additional strike weapon, and individual MEKO upgrade completion remain separate evidence questions.

PROGRAMME DOSSIER / UPDATED 28 OCTOBER 2026
Fleet renewal is a scheduling and sustainment problem as well as a ship purchase.
The strategic task is to convert several overlapping programmes into available ships. Hull numbers alone hide the transition burden: crews must train, new systems must be accepted, existing vessels must enter maintenance and support chains must function together.
Programme status
| Evidence | What it establishes |
|---|---|
| FDI / Kimon class | The Élysée records Kimon’s delivery in January 2026. GDDIA records the fourth-FDI contract amendment signed on 14 November 2025. |
| Italian FREMM | An implementing arrangement was signed on 8 September 2026. Greece’s MOD gives planned transfers of Carlo Bergamini in the first half of 2028 and Virginio Fasan in the first half of 2029. |
| MEKO | GDDIA’s 6 October 2026 notice concerns technical-offer evaluation for the communications workstream. It is not evidence that the entire modernisation is complete. |
| Type 214 | TKMS and Skaramangas announced an industrial MLU partnership on 29 April 2026. Partnership and government programme execution are distinct milestones. |
The strategic and industrial argument
FDI introduces new capability while FREMM offers a different acquisition route through transfer and adaptation. MEKO work seeks to preserve the utility of an existing class. Submarine modernisation concerns another technical and industrial chain. Their schedules interact through personnel, dock capacity and the money available for support.
The fleet-level trade-off is between capability growth and complexity. More suppliers diversify access but also multiply training, spares, software and configuration-management demands. Standardisation helps only when interfaces and support responsibilities are defined.
Greek industrial participation can occur in fabrication, systems manufacture, inspections, integration, maintenance and upgrades. Naval Group’s links with Greek firms and the TKMS–Skaramangas partnership show different routes into this work. Neither makes every Greek yard a qualified supplier for every platform.
Our assessment: the programme that most improves readiness may be the one that removes a support bottleneck, not the one with the largest launch ceremony. Watch accepted delivery, trained crews, weapons availability and maintenance turnaround alongside construction milestones.
How the value chain works
Contract, transfer terms, equipment condition and configuration.
Training, combat systems, communications and acceptance.
Spares, repair capacity and planned availability through the transition.
What determines the outcome
- Monitor ship-by-ship milestones without treating planned dates as achieved.
- Track the scope and award stage of each MEKO package.
- Test local workshare against contracts and accepted outputs.
