The Indonesian Navy has received
the two of four SIGMA class corvettes from the Dutch builders in the last few
months. These ships displace 1,700 tons, are 281 feet long and have a crew of
80. Armament consists of a 76mm gun, two 20mm guns, eight Mistral anti-aircraft
missiles, six torpedoes and four anti-ship missiles (either French Exocet or
Chinese C802). There are radars for navigation, surveillance air defense, as
well as sonar. These ships can stay at sea for about 28 days at a time, and
cost about $490 million each.
