Type 214HN Papanikolis Class Submarine

The Type 214 (Papanikolis class) is the most capable submarine in the Hellenic Navy — a German-designed AIP diesel-electric submarine built under license in Greece. Four boats were ordered: HS Papanikolis (S120), HS Pipinos (S121), HS Matrozos (S122), and HS Katsonis (S123). The Type 214 uses a Siemens PEM fuel cell AIP system providing over two weeks of submerged endurance without snorkeling. The boats fire the UGM-84 Sub-Harpoon anti-ship missile and Atlas Elektronik DM2A4 wire-guided torpedoes. The program was marred by severe construction delays and acceptance disputes but all four boats are now operational.
