Sea Monster is a unique reactive submarine, an aircraft for high-speed movement on waster surface and underwater. The vehicle is designed in the image and likeness of the most powerful and fast marine animal – a tiger shark. Vehicle control is similar to the modern aircraft – it is controlled from the airtight cabin comfortably accommodating a pilot and a passenger. Power plant – a tuned turbocharged engine with capacity of more than 300 hp, with a variable thrust vector, like fighter jets have. It is the fastest underwater vessel in the world, available for free sailing. For the first time, Sea Monster was designed and manufactured exclusively by order of one of the richest Arab sheikhs – Vice President of the United Arab Emirates. Before 2015, it was in Dubai and used for luxury entertainment of the royal family members, personal guests of the Prime Minister and influential politicians. It is one of a kind in Europe and the Russian Federation.
