**Deck**: The decommissioned Greek frigate HS Bouboulina was deliberately sunk in the Sea of Crete during a joint Israeli–Greek naval exercise that used a Greek submarine torpedo, an Israeli SPIKE missile, and a kamikaze-style munition.

The old Hellenic Navy frigate HS Bouboulina has been sent to the bottom of the Sea of Crete in a joint Israeli–Greek live-fire exercise. According to released footage, a Greek submarine fired the torpedo that ultimately sank the ship. The frigate was also hit by an Israeli SPIKE missile and a kamikaze munition.

Using a decommissioned frigate as a live target lets both navies test how specific weapons behave against a real hull, something that simulators and target buoys can’t fully replicate. In this drill, the sequence combined a torpedo launched from a submerged platform with guided munitions delivered from above the surface.

The torpedo strike from the Greek submarine demonstrates Athens’ focus on practicing anti-ship warfare from underwater, one of the most challenging threats for any surface vessel to counter. The Israeli SPIKE missile and kamikaze-style munition add a separate profile: precision weapons able to engage the same ship from distance and from the air.

For militaries watching the exercise, the important details are the mix of platforms and domains involved, and the fact that the target was a full-size frigate rather than a smaller hulk. It offers both countries data on how their systems interact and how quickly a large surface combatant can be disabled or sunk when attacked in this way.

Signals that would show how this drill fits into a broader pattern include announcements of future joint naval exercises in the region, any follow-on training focused on submarine or missile forces, and whether additional retired hulls are earmarked for similar live-fire tests.
