|CE2F/X60 SDV of the Hellenic Navy|
CosMoS CE2F were a series of Swimmer Delivery Vehicle (SDV) built by M/s Cos.Mo.S Spa. which was in Livorno of Italy. Cosmos is probably the most famous military wet-sub (chariot) / midget sub manufacturer in the world. The firm originated in the 1950s when Ing. Sergio Pucciarini, an ex member of the Decima Flottiglia Mezzi d'Assalto (MAS), also known as La Decima or Xª MAS, an Italian commando frogman unit of the Italian Royal Navy, started to build wet subs for civilian and military use. The Hellenic Navy (Πολεμικό Ναυτικό) purchased some SDVs of the CE2F/X60 model (perhaps four) in the late '70s. In service, they were known as ΥΠ.ΟΧ. (Υποβρύχια Οχήματα). The CE2Fs are designed from the outset as a mean for attacking enemy warships in harbor mainly as well as for other special operations.

The craft weights 2,100 kilograms out of water and is 7 or 8 meters long according to type. It is constructed of tough steel and it resembles a torpedo but has two cockpits for the crew. Some models have a roof with sliding doors for the cockpits but the majority of the models are open to water and the passengers must wear full scuba gear. In some models the rear cockpit is long and can seat two divers for a total crew of three. Its battery-electric motors gives it a submerged range of 50 nautical miles (95 km) at four knots, the maximum speed being five and a half knots. For long distance it generally reaches the operating area either attached to or towed by another vessel. A belly-pan beneath its hull can carry special equipment or 230 kg of heavy explosive charges or 150 kg of limpet mines carried in a locker over the aft fuselage. Models of CE2F were also marketed with small 'micro-torpedoes' carried in a belly-pan beneath the cockpit, stated to be for use against divers or small underwater vehicles.

The Greek chariots were operating from the two US-built GUPPY (Greater Underwater Propulsion Power Program) submarines, the Papanikolis (S-114), a Balao class/Guppy IIA submarine (ex-USS Hardhead SS-365) and Katsonis (S-115), a Tench class/Guppy III submarine (ex-USS Remora SS-487). Both boats had the appropriate infrastructure to carry the SDVs as well as they had the escape hatch for OYK divers of the Underwater Demolition Command, the Hellenic Navy's elite special warfare unit. The two GUPPY submarines were decommissioned in the early 1990s and thus gradually after some years the CE2F/X60s were also retired. Unfortunately, nowadays, the Underwater Demolition Command does not have SDVs in her inventory and due to Greece's debt crisis, there is no plan to purchase new ones in the near future.
