The U.S. Navy officially transferred four Mark V Special Operations Craft (MK V SOC) to the Hellenic Navy last week.

The four boats, which have been assigned to the Hellenic Navy’s Underwater Demolition Teams/Navy SEALs (ΜΥΚ), will have to undergo maintenance and refitting before they can requalify as operational.

The MK V SOC packs two MTU 12V396 diesel engines and two Kamewa 50-511 waterjets. The combined power of the diesel engines and waterjets allows the MK V SOC to reach speeds close to 60 miles/hour (around 50 knots); the craft has an operational range of close to 600 miles.

As far as weaponry goes, the MK V SOC packs a heavy load indeed. It can carry an assortment of weapons, including the M2 .50 caliber machine gun, M240 machine gun, M134 minigun, and MK19 40mm grenade launcher. In addition, it can launch remotely piloted aircraft (RPA).

The MK V SOC first entered service with the Naval Special Warfare Command back in the 1990s. Given to the Special Boat Teams and operated by the Special Warfare Combatant-Craft Crewmen (SWCC), the MK V SOC fleet proved its mettle time and again. Indeed, SWCC operators thought very highly of them.

Capable of carrying a crew of five and a platoon of SEALs (about 16 operators) and their equipment, the MK V SOC offers a flexible and reliable transportation and infiltration platform. One of the bigger assets of the vessel is its capability to act as a mothership for Over-the-Beach (OTB), Special Reconnaissance (SR), or Direct Action (DA) operations. In addition to the aforementioned cargo, the MK V SOC can carry up to four inflatable Zodiac rubber boats. Its small size, agile nature, and self-defense capabilities, compared to conventional vessels, make it an ideal platform from where SEALs or other SOF units with maritime capabilities, for example, Marine Raiders, Force Recon platoons, or Special Forces dive teams, can launch operations. And they are also brilliant in transporting larger SOF elements between islands, for instance, the Philippines or the Aegean Sea.

Hellenic Special Operations units fall under two tiers — mind you, these categories are unofficial and have to do more with the unit’s mission and budget allotment.

The below units fall under the first tier. They are almost exclusively manned by full-time personnel:
