The Defense Ministry and the Navy considering christening a new Navy frigate "Cheonan" on the 10th anniversary of the sinking of a corvette of the same name by North Korea.

The frigate will be the first of a fleet of new 3,500-ton frigates to be delivered to the Navy around 2024.

The Cheonan was sunk by a North Korean torpedo in waters off Baeknyeong Island in March 2010.
