The Chien Lung class of submarine, also known as the Hai Lung (Sea Dragon) class, was manufactured in the Netherlands for the Republic of China (Taiwan) and is currently in service with its navy. They are a modified version of the Dutch Navy's Zwaardvis class which itself is based on the US Barbel class.

Planned upgrade[edit]

In 2005, it was reported that the Chien Lung-class submarines would be upgraded to be capable of launching the UGM-84 Harpoon anti-ship missile.[1]

In 2008, the Pentagon notified the United States Congress of the sale to Taiwan of 32 UGM-84 Harpoon Block II missiles, along with two weapon control systems, other associated equipment and services.[2]
