Microsoft cofounder Paul Allen announced Wednesday that he and a crew aboard his "Octopus" yacht had located a WWII-era battleship at the bottom of the ocean in the Philippines.

Octopus is a 414-foot yacht equipped with 40 guest suites, a glass-bottom pool, two helicopter pads, and a submarine.

It is one of the largest yachts on the high seas.

Allen has sailed to Antarctica, the Mediterranean, and many other exotic destinations. "During the day we explore, and at night we jam,"he told"60 Minutes" in 2011.

Octopus has been the scene for numerous swanky parties, including the annual soiree Allen hosts during the Cannes International Film Festival. 

At last year's party, he and "Entourage" star Adrian Grenier entertained guests with a live performance.

Allen started 2015 with another big party onboard Octopus, this time in Sydney.

According to his official web site, Allen has spent eight years looking for the Japanese battleship he found this week, which is called "Musashi." Allen has a passion for military technology, and he owns a large collection of war planes from the same period.
