Visby Class Corvettes, Sweden

This water-based Imperial Star Destroyer is really the spectacular Swedish Visby-Class corvette, the first operational stealth ship in the world, powered with silent waterjets and made with non-magnetic composite materials.

According to the experts, the corvettes are "electronically undetectable at more than 8 miles in rough seas and at more than 13.5 miles in calm seas". Their creation was an answer to the incursion of foreign submarines in Swedish waters in the mid-eighties.

The corvettes are designed to travel at more than 35 knots in between the many beautiful islands that populate Sweden's shallow coast, thanks to waterjets-made by Rolls-Royce subsidiary Kamewa-that reduce their draft. Their mission will be to quickly patrol their territorial waters while hunting for enemy submarines and other ships.
