Greece to Upgrade C-27J Spartan Fleet

Greece has launched a major modernization program for its fleet of Leonardo C-27J Spartan tactical transport aircraft, a move that will extend the operational life of the aircraft and significantly enhance the capabilities of the Hellenic Air Force. The upgrade, announced in recent days, covers all eight C-27Js operated by the 354th Tactical Transport Squadron based at Elefsis Air Base near Athens and is valued at more than €240 million.

The decision is part of Greece’s broader “Agenda 2030” defense modernization plan, which aims to strengthen military readiness and improve interoperability with NATO allies at a time of growing regional security concerns.

Bringing the Spartan to a New Standard

According to details released by French defense publication Air&Cosmos, the Greek Spartans will receive a package of upgrades derived from the latest-generation C-27J configuration.

The modernization includes a new avionics suite featuring a five-screen digital cockpit, upgraded satellite communications systems, enhanced tactical mission equipment and a modern Identification Friend or Foe (IFF) system operating in Mode 5 standard.

The aircraft will also receive an updated TCAS 7.1 collision avoidance system and improvements to their self-protection capabilities. New-generation sensors capable of detecting infrared, laser and radar threats are expected to be integrated, improving survivability in contested environments.

These upgrades will not only enhance operational effectiveness but also ensure compliance with current international aviation standards, allowing the aircraft to remain relevant well into the next decade.

Strategic Significance for Leonardo

The Greek decision represents another important success for Leonardo’s C-27J program in Europe.

While attention often focuses on fighter aircraft acquisitions, tactical airlift fleets play a critical role in military operations, supporting troop deployments, logistics missions, humanitarian operations and rapid crisis response. By investing in the Spartan rather than replacing it, Greece is signaling confidence in the platform’s long-term value.

The program also highlights the growing trend among European operators to extend the life of existing fleets through comprehensive modernization packages rather than pursuing entirely new acquisitions, particularly as defense budgets face pressure from multiple modernization priorities.

For Leonardo, the contract reinforces the attractiveness of the C-27J ecosystem and could serve as a reference for other operators considering similar upgrades in the coming years.

As European nations continue to increase defense spending and revisit force structure requirements, sustainment and modernization programs like the Greek Spartan upgrade may become just as strategically important as new aircraft purchases.
