Hyūga-class destroyer

Hyūga-class destroyer. The Hyūga-class is a pair of helicopter destroyers operated by the Japan Maritime Self-Defense Force. As the first Japanese warships to feature a full-length flight deck since World War II, they represented a significant evolution in Japanese naval shipbuilding and maritime power projection capabilities. Named after former Japanese provinces, the class consists of JS ''Hyūga'' and JS ''Ise'', serving as flagships for escort flotillas and enhancing Anti-submarine warfare and disaster relief operations.

Development and design

The development of the Hyūga-class was driven by the need to replace the aging Shirane-class destroyer and to bolster the Japan Maritime Self-Defense Force's Anti-submarine warfare capabilities against regional submarine threats. The program was approved under the Mid-Term Defense Program in the early 2000s, with design work influenced by the earlier Ōsumi-class tank landing ship and concepts from foreign amphibious assault ship designs like the Spanish Navy's ''Juan Carlos I''. Mitsubishi Heavy Industries was the prime contractor, with construction at its Nagasaki Shipyard in Nagasaki. The design emphasized a large hangar and extensive aviation facilities to operate a substantial rotary-wing air group, marking a departure from previous Japanese destroyer designs focused primarily on missile defense.

Description

The Hyūga-class features a continuous flight deck with a starboard-side island superstructure, resembling a small aircraft carrier. Its primary armament is centered on its air wing, capable of embarking up to 18 helicopters, typically a mix of SH-60K anti-submarine helicopters, MCH-101 mine-countermeasure and transport helicopters, and UH-60J utility helicopters. Defensive systems include a 16-cell Mk 41 VLS launcher for the RIM-162 ESSM surface-to-air missile, two Phalanx CIWS for close-in defense, and two HOS-303 triple torpedo tubes. The ship is equipped with the advanced FCS-3 active electronically scanned array radar system for fire control and the OPS-28 radar for air search. Propulsion is provided by a COGAG system powering two shafts, enabling speeds over 30 knots.

Service history

JS ''Hyūga'' was commissioned on March 18, 2009, followed by JS ''Ise'' on March 16, 2011. Both ships have been assigned as flagships, with Hyūga serving with the Escort Flotilla 2 based at Yokosuka Naval Base and Ise with the Escort Flotilla 4 based at Kure Naval Base. Their operational history includes frequent participation in major annual exercises such as Keen Sword and Malabar, often alongside the United States Navy and other partners like the Indian Navy. They have been deployed for disaster relief missions, including after the 2011 Tōhoku earthquake and tsunami, and for maritime security operations in regions like the South China Sea. In 2021, Ise conducted a historic joint exercise with the navies of Germany, France, and Australia.
