HS Okeanos

The HS Okeanos is a Greek submarine of the Poseidon class built in Kiel, Germany, in the late 1970s and now visible in Palaio Faliro. The vessel was designed for coastal defense and carries powerful torpedo systems suited for protecting shorelines.

Greece was the first country to adopt the Poseidon class and ordered four of these submarines from Kiel. These vessels belonged to the larger 209/1200 series that was later sold to numerous countries worldwide.

The submarine sits in the water near the cruise ship harbor and is easy to spot from the shore. An old turret from the vessel stands as a monument in a nearby park and can be visited freely.

The turret in the park looks like a freestanding small tower and draws visitors who want to learn about Greek naval history. The installation honors the crews who served on Greek submarines over the years.
