기타 해상자위대, 히비키급 SURTASS선 4번함 빙고함 진수

[위종민]

2월 17일 MHI가 히비키급 SURTASS선 4번함인 빙고함을 진수시켰습니다. 취역 예정일은 2026년 3월이고, 건조비는 196억 엔 (1억 2920만 달러)였다고 합니다. 센서 포함한 총 건조비일까요?

히비키급 SURTASS선은 1991년, 1992년 두 척이 진수된 후 2021년 3번함인 아키함이 취역했으며, 그간 3척 / 4개 승조팀(crew system) 체제를 운영중이었는데 빙고함의 취역으로 4척 / 5개 승조팀 체계를 구성해 가동률을 높일 수 있다고 하네요. 히비키급이 소속된 Ocean Surveillance Division 1 (정식 부대명칭이 뭔질 모르겠네요.)은 2017년 처음으로 crew system 체계를 도입했고, 아직도 해자대에서 유일하게 해당 제도를 운영중이라고 합니다.

On February 17, 2025, Japanese shipbuilder Mitsubishi Heavy Industries Maritime Systems Co., Ltd. launched the fourth Hibiki-class auxiliary ocean surveillance ship on order for the Japan Maritime Self-Defense Force (JMSDF).

The new auxiliary ocean surveillance ship, which has been named “Bingo”「びんご」(with pennant number AOS 5204), entered the water in a ceremony held at the company’s shipyard in Tamano City, southern Okayama Prefecture on the day.

The vessel is named after the Bingo Sea (備後灘, Bingo-nada) which is an area of ​​water in the central part of the Seto Inland Sea. All ships of the Hibiki-class are named after famous “nada” (sea) along the coasts of each region.

The shipyard will now proceed to the fitting out stage of the ship, ahead of its delivery and commissioning set for March 2026, according to the JMSDF. The Bingo was laid down in March 2024.

The small waterplane area twin hull (SWATH) vessel is expected to be inducted into the service’s Ocean Surveillance Division 1 at the Kure naval base in Hiroshima Prefecture, a JMSDF spokesperson told Naval News. This division is the JMSDF’s only surveillance division.

The spokesperson told Naval News that the Bingo is being built for about 19.6 billion yen ($129.2 million) under a contract awarded in March 2023.

The U.S. Navy Surveillance Towed Array Sensor System (SURTASS) is a low-frequency array of hydrophones that is deployed from surface ships and receives acoustic data. U.S. Navy image / SURTASS LFA sonar program.

The 67 m-long vessel features a more advanced Surveillance Towed Array Sensor System (SURTASS) than that fitted onto the first two ships of the class – JS Hibiki (AOS 5201) and JS Harima (AOS 5202) – which entered service in 1991 and 1992, respectively. It has a standard displacement of 2,900 tonnes, the same as JS Aki (AOS 5203), and 50 tons larger than JS Hibiki and JS Harima.

The Hibiki-class has a top speed of 11 kt, according to the JMSDF. The vessels, each of which has a crew of 40, also feature a flight deck for helicopter operations.

The spokesperson said the JMSDF aims to further enhance the service’s capability to gather acoustic information in the seas by increasing the number of its auxiliary ocean surveillance ships from three to four, as Japan’s security environment is becoming even severer. As the number of auxiliary ocean surveillance vessels increases, the JMSDF will have more eyers, or sensors, in the seas.

The Ocean Surveillance Division 1 was the first in the JMSDF to introduce a crew system in 2017, and is still the service’s only division that operates with the crew system. With the commissioning of the third vessel, Aki, the division has been so far operating three vessels with four crew teams alternating between them, without a fixed crew on the ships.

According to the JMSDF, once JS Bingo is commissioned, the division will have a five-crew system with four vessels, which will increase the operational rate.

The Ocean Surveillance Division 1 is under the control of Oceanography ASW (Anti-submarine Warfare) Support Command at the Yokosuka naval base in Kanagawa Prefecture, south of Tokyo.

All ships of the class are mobile sonar listening stations designed to track submarines in the seas around Japan. The JMSDF developed the Hibiki-class in response to the Soviet Navy’s increasingly quiet submarines of the 1980s.

With China increasingly developing its nuclear-powered submarine capabilities and Russia launching new types of submarines, Japan is currently looking to enhance its anti-submarine warfare capabilities.

The Hibiki-class has a top speed of 11 kt, according to the JMSDF. The vessels, each of which has a crew of 40, also feature a flight deck for helicopter operations.
