Overview of the live-fire acceptance trial
The Hellenic Navy conducted live-fire acceptance trials north of Crete on 21 October 2026, firing Israeli-made SPIKE NLOS and SPIKE ER missiles from a Machitis-class patrol vessel and a MARK V special operations boat. Senior naval commanders from Greece and Israel observed the exercise. The trial validated weapon performance, integration with shipboard launch procedures, and command-and-control links between launch platforms and remote operators.
Which platforms launched the missiles and why those platforms matter
Machitis-class patrol craft are highly automated vessels optimized for littoral operations and fast reaction tasks; Their modular fit allows missile canisters and targeting systems to be integrated without major hull changes. MARK V special operations boats provide low-signature, high-speed launch capability in shallow waters and tight coastal environments. Using both platforms demonstrated the SPIKE family’s flexibility across a range of naval mission profiles: sea-control, coastal denial, and special-operations support.
Target selection and sequence of events during the trial
The exercise used the decommissioned frigate Bouboulina (F-463) as the target to reproduce realistic strike geometry and terminal effects on a full-sized surface warship. Sequence of events:
1. Pre-launch preparation: command teams performed data-link checks, target designation verification, and launch-envelope safety clearances.
2. Launch: SPIKE NLOS and SPIKE ER rounds were fired from the Machitis-class craft and the MARK V boat against prepared aim points on the target ship.
3. Mid-course control and terminal guidance: the SPIKE NLOS operator used the two-way data link and electro-optical feed to observe the missile in flight, update aim points, or abort if required.
4. Post-impact assessment: observers verified hit accuracy and damage effects. The final sinking was completed by a torpedo fired from a submarine, ensuring complete neutralization of the target hull and providing data on cumulative lethality.
SPIKE NLOS and ER capabilities demonstrated
SPIKE NLOS (Non-Line Of Sight) and SPIKE ER (Extended Range) are electro-optically guided missiles with distinct operational envelopes. Key capabilities shown during the exercise:
SPIKE NLOS: up to ~32 km effective range from sea or land launch; two-way data link allows in-flight target confirmation, re-designation, and mission abort; EO/IR seeker provides image-based terminal homing with day/night capability.
SPIKE ER / ER2: ER baseline ~8–10 km from surface platforms; ER2 increases range to ~10 km (surface) and up to ~16 km when fired from helicopters. The ER family emphasizes a lower-cost, shorter-range option for quick anti-ship engagements in coastal areas.
Operational implications for Greek and regional naval forces
The trial produced several practical takeaways for operational planners:
1. Distributed lethality: equipping patrol craft and special-ops boats with precision-guided missiles distributes firepower across many hulls rather than concentrating it on a few major surface combatants
2. Escalation control: two-way data links and in-flight abort provide finer control of escalation by enabling human-in-the-loop termination of strikes if rules of engagement or situational awareness change.
3. Interoperability: demonstrated end-to-end mission execution with Israeli naval units highlights procedural and communications interoperability—useful for alliance or bilateral task groups operating in the Eastern Mediterranean.
Damage effects and lessons learned from the live-fire impacts
Observers reported precise aim-point strikes and predictable terminal damage consistent with warhead design and approach vector. Using a decommissioned frigate produced data on hull penetration, subsequent progressive flooding, and structural collapse sequences. Lessons learned included fine-tuning of launch parameters for small-boat motion compensation, optimizing sensor handover procedures between launch teams and remote operators, and validating the robustness of the two-way data link under maritime environmental conditions.
Command-level diplomacy and operational cooperation
Senior officers present—Greece’s Chief of Defense, the Hellenic Navy Commander, and the Israeli Navy Commander—used the event to discuss joint tactics, training exchanges, and technology-sharing avenues. Leaders emphasized cooperative solutions for regional security challenges such as freedom of navigation, maritime domain awareness, and countering asymmetric coastal threats.
How this trial compares with other maritime missile trials
Compared with similar naval evaluations, this trial combined three notable elements: dual-platform launches (small patrol craft and fast boats), real-time two-way operator control during flight, and a full-ship target assessment culminating with a submarine torpedo finalization That combination yields richer data than single-platform trials or land-launched missile tests, helping navies assess both system performance and operational integration.
Questions commanders will likely face when operationalizing SPIKE at sea
Practical questions fleet commanders will address next include:
– Logistics and sustainment: how to stock warheads and spare launch canisters aboard small ships and ensure safe handling.
– Training: creating syllabus and simulator profiles so operators can exercise image-based targeting, manual aim updates, and abort procedures under stress.
– Rules of engagement and legal review: defining authorization workflows for remote in-flight target confirmation in congested littoral environments.
Conclusions and forward steps
The acceptance firing north of Crete validated SPIKE family performance from naval platforms, reinforced bilateral maritime cooperation, and supplied actionable data on small-boat launch integration and battle damage effects. Next steps typically include formal acceptance paperwork, expanded training cycles for crews and operators, logistical integration into ship stores, and further interoperability trials with allied navies to refine tactics and procedures.
