Swedish archaeologists find 17th-century warship

Maritime experts believe wreck is sister ship of Vasa, which sank off Stockholm in 1629

Swedish maritime archaeologists have discovered the long-lost sister ship of the 17th-century warship Vasa, which sank on its maiden voyage, the Swedish Museum of Wrecks has said.

Launched in 1629, Applet (Apple) was built by the same shipbuilder as the famed 69-metre Vasa, which was carrying 64 cannon when it went down in a strait off the island of Vaxholm, just outside the capital, Stockholm.
