Cheonanham SpecificationsUpdated: 2010-03-27 12:00:00 (KST)
The South Korean Navy ship "Cheonanham" which sank on Friday night Korea time is a 1,200-ton corvette dispatched to the second Navy Security Command in Pyeongtaek.
Built in 1984, Cheonanham or PCC-722 is one of South Korea's 24 combat vessel series that guard against possible military attacks in coastal areas.
Smaller than the scale of a convoy, it is a lightly armed warship equipped with missiles, antisubmarine bombs and torpedoes.
With a length of 88 meters and a width of 10 meters the ship can sail up to 7,200 kilometers after initial departure at a maximum speed of 57 kilometers per hour.
Cheonanham is known to have been involved in the Yeonpyeong maritime clash between the Navies of South and North Korea in 1999.
Corvettes are divided into either a "Donghae" or "Pohang" class and the demised Cheonan ship falls under the Pohang class which is an attacker-type warship that exclusively serves military purposes, with the capacity of carrying approximately 100 crew members.
