Israeli and Greek navies practise sinking a hostile vessel in joint drill

The navies of Israel and Greece have carried out a joint exercise in the Mediterranean Sea, with the commanders of both forces leading the drill, according to a statement posted by the Israel Defense Forces (IDF) on X. The IDF said the participating crews rehearsed spotting and dealing with threats at sea, operated together as a single combined task force, and used missile fire to sink a vessel designated as hostile.

The Jerusalem Post also reported the drill, describing it as an exercise focused on operational scenarios that included sinking hostile ships. The IDF framed the training as a way of deepening practical cooperation between the two countries and of building shared capacity to respond to emerging threats while keeping sea lanes secure and open.

Who took part

On the Israeli side, the participating force was the Israeli Navy, the maritime branch of the IDF. The Israel Defense Forces is the country's unified military, so the navy sits within the same command structure as the ground and air forces rather than as a separate service. Its spokesperson's unit regularly publishes accounts of training and operations on social media, which is where this exercise was first announced.

The Greek partner was the Hellenic Navy, the official name of Greece's naval force. "Hellenic" is the term Greece uses for itself in official contexts, and readers will often see it in the names of Greek state institutions. According to the IDF, the exercise was led jointly by the heads of the two navies, which indicates it was conducted at the level of the services themselves rather than by a single unit.

What the crews practised

The IDF statement lists three main elements of the training. The first was identifying and neutralising maritime threats, a broad category that in naval terms can cover anything from hostile surface vessels to other dangers approaching ships or coastlines. The statement does not specify which kinds of threats were simulated.

The second element was sailing as a joint task force. A task force is a temporary grouping of ships assembled for a particular mission; operating as a combined one requires navies to share communications, procedures and command arrangements so that vessels from different countries can manoeuvre and respond together.

The third, and the one highlighted in the Jerusalem Post headline, was the live use of missiles to sink a target treated as an enemy ship. The IDF did not say what the target was or what weapons were fired.

The stated purpose

In its post, the IDF presented the exercise as strengthening operational cooperation between Israel and Greece. It tied the drill to two goals: improving joint capabilities to deal with emerging threats, and maintaining security and freedom of navigation. Freedom of navigation is the principle that commercial and other ships should be able to move through international waters without obstruction, and it is a recurring theme in how navies describe their missions in busy seas such as the Mediterranean.

The statement did not name any specific country, group or incident as the threat the exercise was designed to address, and this report does not attribute one.

Where the reports differ

The two reports are broadly consistent, but there is one difference in detail. The IDF statement refers to sinking a single hostile vessel. The Jerusalem Post headline refers to sinking hostile ships, in the plural. The available material does not resolve whether one target or more than one was sunk during the exercise.

The timing of the reports is also worth noting. The IDF post appeared first, and the Jerusalem Post report followed the next morning. The Jerusalem Post item, as available, consists mainly of a headline and a file photograph of an Israeli Navy patrol boat off Haifa, so it adds little independent detail beyond the IDF account.

What the reports do not say

• The date or dates on which the exercise took place, as distinct from when it was announced.
• Where in the Mediterranean the drill was held, and whether it was closer to Israeli or Greek waters.
• How many ships, aircraft or personnel from each navy took part, and which vessels were involved.
• What kind of target was sunk, what missiles were used, and whether the sinking involved one vessel or several.
• Whether this was a one-off event or part of a regular series of exercises between the two navies.
• Any comment from the Hellenic Navy or the Greek government; the account available comes from the Israeli side.
