Kraka, or UC2 Kraka was an amateur-built midget submarine completed in 2005, the first diesel–electric amateur sub in Denmark.[1] It was built by Peter Madsen, Claus Nørregaard[5] and several other people. The overall length was 12.6 meters (41 ft), and it displaced 6 tonnes. The propulsion was diesel–electric with a 16 hp diesel engine and an 8 hp electric motor. Kraka can be seen at Denmark's Technical Museum in Elsinore (aka Helsingør).[6][7][2] Kraka is named after a woman in Norse mythology known for her intelligence.[3]
