In September 2018, Taiwan confirms contract for first amphibious assault ship built in Taiwan. It will be built by CSBC Corporation, a local shipyard. Four are planned with the first to be entering service around 2021. It is roughly similar to US Navy's San Antonio class, but with a slightly smaller displacement. Support features include a full hospital, well deck, full aviation facilities, storage for wheeled vehicles, and dedicated accommodations for a full battalion of Marines. The vessel design will be armed with a 76 mm naval gun in the primary position, a close-in weapon system (CIWS) turret, two 12.7 mm machine gun positions in the forward section, and launchers that can deploy the Hsiung Feng II and III family of anti-ship and land-attack cruise missiles. The primary sensor is expected to be a naval version of the indigenous CS/MPQ-90 Bee Eye AESA radar.
Yushan-class ships has a length of 153 m (502 ft), a beam of 23 m (75 ft), and their standard displacement is 10,000 t (9,800 long tons). The class has a draught of 6.1 m (20 ft), maximum speed of 21 knots (39 km/h) and range of 7,000 mi (11,000 km).
The ships are able to carry several AAV7 amphibious APCs along with 673 troops. The ships also has a single flight deck with two hangars able to accommodate Sikorsky UH-60 Black Hawk or the naval Sikorsky SH-60 Seahawk helicopters.
The class is unusually well armed for a landing platform dock with a 76 mm gun, two Phalanx CIWS, and two modular missile launchers of either 8 Hsiung Feng II surface-to-surface missiles or 16 Hai Chien surface-to-air missiles. They also have radar signature reducing features and electromagnetic pulse protection.
The lead ship of the class cost $4.635 billion NTD ($163 million USD).
