December13, 2006: Less than a year after deciding to build several large, 3,000 ton, diesel-electric subs, South Korea has thought better of it, and canceled the project. Instead, six more 1,600 ton Type 214 subs will be built over the next 14 years, in addition to the three already planned. South Korea already has nine 1,100 Type 209 subs, designed and built in Germany. The Type 214s are also a German design, but will be built in South Korea. The Type 214 boats use fuel cells, enabling them to stay underwater for a week or so at a time. The South Koreans like their 209s, but are now getting nervous because the first 214 recently received by Greece, had a long list of problems.
