Due to the significant advances in the Taiwanese Navy's second-generation fleet, the old traditional Tug Boats were unable to provide the maneuverability, speed and power which are necessary to quickly and safely pull the new big warships into port or to quickly mobilize in case of war. In accordance with Taiwan's national defense policy, the policy of domestically building Taiwan's Navy, and due to the yard's vast experience which was acquired by structuring tugboats for Kaohsiung's Harbor Bureau, Ching Fu was appointed to design and built eight new type Tug Boats for the Taiwanese Navy.

In conjunction with the Navy, Ching Fu created the building plans and strategy for these Tug Boats which have loads of 1800 HP and are equipped with 360 degrees Steerable Rudder Propeller (Z-drive Propeller). These Naval tugboats not only satisfy the rigorous standards of the U.S. Navy in terms of intact stability and damage stability, but are also able to meet the demands of non-combat for a period of fifteen to twenty years. Furthermore, these Tug Boats are designed to transport light arms around a war zone during wartime.

Complying with strict Naval standards, Ching Fu built these eight Tug Boats to surpass the functionality and quality of all other standard tugboats. These 1800 HP Tug Boats are not only able to superbly perform the customary operations of mobile rotation and the towing of big warships but are also fitted to with a general marine sprinkler hull protection system, a fire fighting system for warships and have oil pollution clean up capacity.
