Russian billionaire Roman Abramovich is the owner of the world’s biggest and most hi-tech yacht. The yacht measures nearly 560 feet long and is aptly named Eclipse for when it towers over and covers another smaller yacht on the open seas. The yacht sports an on-board missile defense system (WHAAATTTT), an anti-paparazzi laser shield (this one is interesting), and a personal submarine.

If you want one for yourself you’ll have to fork over $450 million. Easy, right? [via]
