Brazil recently ordered more ($43 million worth) Norwegian Penguin anti-ship missiles for use by their navy helicopters. Four years ago Brazil bought a dozen Penguins and were sufficiently satisfied with the missile that they bought 40 more. The Penguin weighs 370 kg (814 pounds) and has a range of 55 kilometers. The Penguin has been in service since 1973, and has been constantly upgraded. The current version costs about a million dollars each. The missile has been exported to many countries, including the United States, and is carried by F-16s, various types of helicopters, and small warships.
