JS Yūdachi (DD-103) is a Murasame-class destroyer of the Japan Maritime Self-Defense Force, commissioned on 4 March 1999. As the third vessel of its class, Yūdachi features a significantly renovated hull design compared to first-generation destroyers, aiming to enhance stealth and reduce underwater radiation noise. Its hull and superstructure are inclined to lower radar cross-section, although it lacks the angled tripod mainmast seen on some American vessels like the Arleigh Burke class, due to the heavy winter weather conditions in the Sea of Japan. The aft section is designed with a "mini-Oranda-zaka" style, similar to the Kongō class, to prevent interference between helicopters and mooring equipment. Yūdachi's propulsion system is a COGAG (Combined Gas and Gas) arrangement, similar to the Asagiri class, but with updates: one pair of engines is equipped with Spey SM1C turbines, while the other pair uses LM2500 turbines, akin to the Kongō class. The ship was laid down on 18 March 1996 at Sumitomo Heavy Industries in Yokosuka and launched on 19 August 1997. Throughout its service, Yūdachi has participated in various operations, including anti-piracy missions off Somalia and the Gulf of Aden, notably departing on 6 March 2016 and returning on 8 September. It also conducted goodwill missions, such as a training exercise with the Philippine Navy’s BRP Rajah Humabon in September 2016. In 2021, Yūdachi joined joint training exercises in the South China Sea with USS Jackson and participated in multinational drills, including MILAN 2022 in India. The vessel has also engaged in several US-Japanese joint exercises, including operations with USS Robert Smalls, USS Ronald Reagan, USS Carl Vinson, and other allied ships, demonstrating its ongoing role in regional security and international cooperation.
