Currently, Taiwan's naval assets comprise two submarines from the 1980s, designed in the Netherlands. Over the years, various challenges, both internal and external, have impeded the nation's ambition to develop its submarine fleet. However, a renewed emphasis emerged in 2016, propelling efforts towards domestic submarine production.

The new diesel-electric submarine, outfitted with MK-48 torpedoes, is the first in a series of planned additions. Testing is set to commence on Sept. 28, followed by harbor acceptance trials starting Oct. 1.

These preliminary evaluations are expected to wrap up by April 1, 2024. The subsequent sea acceptance tests are on the horizon, though their specific timeline remains undetermined. The goal is for the submarine to join the naval fleet by the following year.

Taiwan has plans to roll out another seven submarines of a similar design, which will increase its fleet size to ten. This expansion is anticipated to enhance Taiwan's maritime strategy and positioning.

Technical data

Taiwan's Indigenous Defense Submarine has a submerged displacement of over 2,500 metric tons, equivalent to 2,460 long tons or 2,760 short tons. The submarine can reach dive depths between 350 to 420 meters.

The vessel measures 70 meters in length, corresponding to 230 feet as per the 3.05 version, and has a width of 8 meters, which is 26 feet based on the 3.05 version.
