Neptune’s Navy
The Sea Shepherd Fleet
Since 1977, a number of vessels have served in the Sea Shepherd fleet to protect marine wildlife in direct-action campaigns around the world. Today, our international fleet includes ten vessels and several smaller boats used in our ocean conservation campaigns.



Ocean Warrior

Overview
In 2015, at the annual Goed Geld Gala (Good Money Gala) hosted by the Dutch Postcode Lottery in Amsterdam, Sea Shepherd Global was awarded €8.3 million for a “Dream Project” vessel built to "Stop Illegal Fishing in the Southern Ocean".
It was constructed by Dutch shipbuilder Damen in the port of Antalya, Turkey, and christened Ocean Warrior in September 2016. Its maiden voyage was Operation Nemesis, Sea Shepherd’s 11th Antarctic Whale Defense Campaign, in 2016/2017.
The M/Y Ocean Warrior is Sea Shepherd’s first custom-built ship, and the fastest in the fleet, reaching speeds over 25 knots.

Bob Barker

Overview
Thanks to a $5 million contribution from the legendary American game show host Bob Barker, in 2009 Sea Shepherd secretly purchased and refitted a former Norwegian whaler in Africa. The ice-strengthened chaser boat quietly departed from Mauritius on December 18th for its first mission against the Japanese whaling fleet, Operation Waltzing Matilda.
The Bob Barker originally operated as a whaling ship until 1962, and later confronted Sea Shepherd during its life as a Norwegian Coast Guard vessel.

Age of Union

Overview
The Age of Union, previously known as the Sam Simon, was named after our partners at the Age of Union Alliance, following a very significant pledge of support at the very beginning of 2022.
The vessel first joined the Sea Shepherd fleet under the name Sam Simon, after the Hollywood producer and animal rights advocate who served on Sea Shepherd’s Board of Advisors until his passing in 2015. His generous donation made it possible to purchase the former Japanese vessel in 2012, when it joined its first Antarctic Whale Defense Campaign that December, Operation Zero Tolerance.
The Sam Simon, originally named the Seifu Maru, was a Meteorological Observation Ship for the Japanese whaling fleet.

Selkie

Overview
Sea Shepherd's first landing craft was named by Captain Paul Watson after the Selkies (seal folk) from Celtic and Norse mythology.
Commissioned by the Ministry of Defence in 1984 and completed in 1985 at the Souter shipyard at Cowes (Isle of Wight, UK), the Landing Craft Vehicle Personnel (LCVP) Mk.4 was designed to operate from the Royal Navy's amphibious warships HMS Fearless and HMS Intrepid. Decommissioned in 2012 then fully re-built in 2016 with further modifications in recent years, LCVP Selkie opens up more possibilities for Sea Shepherd UK's campaigns than traditional boats and RIBs with the ability to land on almost any beach, embark a load of 5500 kg and then retract back to the sea.
LCVP Selkie will now be tasked on coastal patrol work, diver deployment, ghostnet recovery, and marine debris retrievals from otherwise inaccessible areas of the UK's coastline and islands.

Its first expedition was the 2006/2007 Antarctic Whale Defense Campaign Operation Leviathan.
The ship was renamed Steve Irwin in December 2007 in honor of the late Australian conservationist and Sea Shepherd supporter. Retired in 2018, the Steve Irwin has embarked on more ocean defense campaigns than any other current Sea Shepherd vessel.
