JS Mikuma (FFM-4) named after the Mikuma River (Mikuma-gawa) located in Oita Prefecture was launched by local shipbuilder Mitsubishi Heavy Industries (MHI) in Nagasaki on 10 December 2021.

The FFM (also known as 30FFM and previously known as 30DX) is the next generation multi-mission frigate designed for the JMSDF. A total number of 22 Frigates are expected to be procured for the JMSDF.

The two shipyards in charge of building the first two frigates of the class are Mitsubishi Heavy Industries (MHI) in Nagasaki and Mitsui E&S in Okayama.

 

Mogami-class FFM

According to MHI, the FFM multi-mission frigate will have a full load displacement of about 5,500 tons, with a length of 132.5 meters/435 feet and a beam of 16.3 meters/53.5 feet. It will have a maximum speed in excess of 30 knots/34.5 mph/55.5 km/h. The crew complement will be quite low, at about 90 sailors, indicating a high level of automation on board.

The FFM will be equipped with a wide variety of weapons and systems as listed below:

  • BAE Systems Mk.45 mod.4 5-inch/127-mm naval gun system ×1;
  • Japan Steel Works 12.7-mm Remote Weapon System ×2;
  • 41 VLS;
  • Raytheon SeaRAM ×1;
  • MHI Type 17 anti-ship missiles ×8;
  • Mitsubishi Electric OPY-2 multifunction Radar;
  • Mitsubishi Electric OAX-3 Electro-Optical/Infra-Red (EO/IR) sensors;
  • Hitachi OQQ-11 anti-mine sonar;
  • NEC OQQ-25 anti-submarine sonar (Variable Depth Sonar/Towed Array Sonar Systems – VDS/TASS);
  • UUV (OZZ-5 by MHI) and Unmanned Surface Vehicle (USV) for mine counter measures;
  • Sea mines for offensive mine warfare.

 

Funding for the installation of Mk.41 VLS

Initially, the Mogami-class was only «Fitted For But Not With» (FFBNW) Mk.41 Vertical Launch System (VLS). This changed at the end of 2021: in late November, the Japanese Ministry of Defense announced the supplementary budget for FY2021, which included a budget for two VLSs sets for FFM ships. Two FFM frigates will get 16 cells each (allowing for a total of 32 quad-parcked ESSM each). The total supplementary budget is about $6.8 billion, of which about $74 million is for the purchase of the VLS shipsets. Originally, the FFM 9 and 10 specified in the defense budget request for FY2022 included a budget for VLS. Therefore the VLS specified in this supplemental budget is for installation on any of the FFM ships 1 through 8.

3rd Taigei-Class Submarine

According to Naval News, Japan’s newest submarine JS Jingei (SS-515) was launched on October 12, 2022 at the Mitsubishi Heavy Industries (MHI) shipyard in Kobe. It is the third boat of the new Taigei-class, the latest class of advanced diesel electric submarines (SSK) for the Japan Maritime Self-Defense Force (JMSDF).

Jingei means «fast swimming whale» in Japanese and was once used as the name of a submarine tender of the Imperial Japanese Navy. Taigei-class submarines are named after whales or large fishes.

The first submarine of the class, Taigei (meaning «Great Whale») was launched by MHI in October 2020 and commissioned with the JMSDF in March 2022. Kawasaki Heavy Industries (KHI) launched the second one, Hakugei (meaning «White Whale»), in October 2021. Jingei is set to be delivered to the JMSDF in 2023.

The external appearance of the Taigei is not much different from the Sōryū-class, but inside of it is a completely different submarine. First, the Taigei uses lithium-ion batteries instead of the 4V-275R Mk. III Air-Independent Propulsion (AIP) system, which was installed aboard the first 10 Sōryū-class submarines.

Secondly, the capabilities of the sonar and combat command system have been improved, as well as the use of new acoustic absorbent materials and a floating floor structure to make it quieter. It is also equipped with Torpedo Counter Measures (TCM), which eject decoys to evade enemy torpedoes for improved survivability.

The first-in-class Taigei will be used as a test submarine, according to the «National Defense Program Guidelines for FY 2019 and beyond» published in December 2018. In other words, Taigei will be the dedicated ship to conduct all future tests of technology related to JMSDF submarines.

Great Whale

According to Naval News, Japan’s newest submarine JS Taigei (SS-513) (previously known as 29SS) was launched on October 14, 2020 at the Mitsubishi Heavy Industries (MHI) shipyard in Kobe, Hyogo Prefecture.

Taigei means «Great Whale» in Japanese and was once used as the name of a submarine tender of the Imperial Japanese Navy. The Japan Maritime Self-Defense Force (JMSDF) uses the names of submarines to refer to (1) things related to oceanographic phenomena, (2) legendary creatures and (3) underwater animals. This leaves three main classes of submarines to be operated by the JMSDF in the future: the Oyashio-class is named after underwater currents and tides, the Sōryū-class submarines are named after dragons, and it appears that the new Taigei-class will be named after whales or large fishes.

The external appearance of the JS Taigei (SS-513) is not much different from the Sōryū-class, but inside of it is a completely different submarine. First, the JS Taigei (SS-513) uses lithium-ion batteries instead of the 4V-275R Mk. III Air-Independent Propulsion (AIP) system, which was installed aboard the first 10 Sōryū-class submarines.

Secondly, the capabilities of the sonar and combat command system have been improved, as well as the use of new accoustic absorbent materials and a floating floor structure to make it quieter. It is also equipped with Torpedo Counter Measures (TCM), which ejects decoys to evade enemy torpedoes for improved survivability.

The contract is part of a larger $4.5 billion modernization program, announced by the U.S. Government in October 2019. The upgrades will introduce state-of-the-art electronic warfare and weapons. An all-new advanced cockpit system, running on the world’s most advanced mission computer, will deliver pilots enhanced situational awareness.

Under the agreement, Boeing will provide MHI with retrofit drawings, ground support equipment and technical publications for the upgrade of the first two F-15J aircraft to the Japan Super Interceptor configuration.

Boeing has partnered with MHI in the defense arena since the 1950s. MHI produced under license the current Japan F-15J fleet of over 200 aircraft between 1980 and 2000, and will serve as prime contractor for the upgrade. Sojitz Corporation, a trading company that works with Boeing’s team in Japan, will support this effort.

«Through this agreement, Boeing is honored to further our long-standing tradition of support for Japan’s Ministry of Defense, the Japan Air Self-Defense Force, and MHI», said Will Shaffer, Boeing Japan President. «These upgrades will deliver critical capability for national and collective self-defense, in which the F-15J plays a key role. At the same time, they will provide MHI and our partners in Japan’s aerospace defense industry with an opportunity to enhance their own extensive engineering capabilities».

This DCS contract lays the foundation of the modernization program. MHI will develop the detailed modification plan for the jets and prepare the facilities and workforce for the induction and upgrade of up to 98 aircraft beginning in 2022.

Multirole Frigate

According to the post Kosuke Takahashi, correspondent of the magazine IHS Jane’s Defence Weekly, Mitsubishi Heavy Industries (MHI) announced on 1 November that it has been awarded a contract by the Japanese Ministry of Defense (MoD) to build the first two of four ships of a new class of multirole frigate for the Japan Maritime Self-Defense Force (JMSDF).

Although MHI did not disclose the value of the contract, the MoD had earmarked JPY92.2 billion (USD816 million) in its budget for fiscal year 2018 for the construction of the two 426-foot/130-meter-long, 42.6-foot/13-meter-wide frigates, which are expected to be handed over to the JMSDF in March 2022.

In August the MoD requested JPY99.5 billion from Tokyo for the construction of the two remaining vessels, with delivery expected to take place in March 2023. However, the contract for these two ships has yet to be awarded.

MHI’s frigate design and proposal were selected over those submitted by Mitsui Engineering and Shipbuilding (MES) and Japan Marine United. MES, however, was chosen to be the subcontractor.

Construction of the first 3,900 tonne ship will take place at MHI’s Nagasaki Shipyard & Machinery Works in Nagasaki Prefecture, while the second one will be built at MES’s Tamano Shipyard in Okayama Prefecture. The arrangement marks the first time that MHI will build a ship as the lead contractor.

According to the MoD, this new frigate class, which is intended to carry out surveillance missions in waters surrounding the Japanese archipelago, will be equipped with enhanced multirole capabilities, including the ability to conduct anti-mine warfare operations, which until now have been performed by the JMSDF’s ocean-going minesweepers.

Armament on the frigates, each of which will be capable of embarking one helicopter as well as unmanned surface and underwater vehicles, is expected to include the navalised version of the Type-03 (also known as the «Chū-SAM Kai») medium-range surface-to-air missile, a 5-inch (127-mm)/62-calibre gun, a Vertical Launch System (VLS), canister-launched anti-ship missiles, and a SeaRAM (Rolling Airframe Missile) close-in weapon system.
