Japan confirms first operational integration of the PLAN’s Type 054B / Jiangkai III-class frigate into a carrier strike group formation.
Japan’s Joint Staff Office (JSO) announced on May 26 that the Japan Maritime Self-Defense Force (JMSDF) had tracked a five-vessel People’s Liberation Army Navy (PLAN) formation in the Western Pacific, led by the aircraft carrier Liaoning (CV-16). The group included the newly commissioned Type 054B frigate Luohe (545) — marking the first publicly confirmed deployment of a Jiangkai III-class frigate as part of a PLAN carrier strike group.
The formation was detected on May 25 approximately 880 kilometers southwest of Okinotorishima, the southernmost island in Japan.
The following day, the JMSDF also confirmed repeated fixed-wing and rotary-wing flight operations from Liaoning’s flight deck. The JMSDF destroyer JS Asahi (DD-119), homeported in Sasebo, Nagasaki Prefecture, conducted surveillance and intelligence-gathering operations throughout the deployment.
Formation Composition
According to the JSO announcement, the formation comprised the following vessels:
CV-16 Liaoning (Kuznetsov-class aircraft carrier)
DDG-104, a Type 055 Renhai-class destroyer
DDG-124, a Type 052D Luyang III-class destroyer
FFG-545 Luohe, a Type 054B Jiangkai III-class frigate — marking the class’s first confirmed carrier group deployment
AOR-901 Hulunhu (Type 901 Fuchi-class fast combat support ship)
The JSO further noted that Luohe (545) and Hulunhu (901) are the same vessels confirmed transiting the Miyako Strait — the strategic waterway between Okinawa and Miyakojima — on May 19, proceeding southeast into the Western Pacific. That transit also marked the first confirmed deployment of a Type 054B beyond the so-called first island chain stretching from Japan through Taiwan to the Philippines.
The Type 054B (NATO: Jiangkai III) is the PLAN’s newest frigate class and the designated successor to the prolific Type 054A (Jiangkai II), of which China operates over 30 hulls. Luohe is the lead vessel of the class, commissioning in January 2025.
Carrier Strike Group Architecture Implications
The composition of the May 25–26 formation offers the clearest picture to date of the PLAN’s emerging carrier strike group template. The pairing of a Type 055 (DDG-104) serving in the high-end air defense and strike role with a Type 054B likely intended for ASW and escort functions appears to mirror the escort architecture commonly seen in U.S. Navy carrier strike groups, where Ticonderoga-class cruisers and Arleigh Burke-class destroyers perform comparable functions across different layers of defense.
The inclusion of a Type 901 fast combat support ship (AOR-901) is operationally significant. At approximately 45,000 tons full load, the Hulunhu-class provides underway replenishment of fuel, aviation ordnance, and stores at a scale that supports extended far-seas deployments, suggesting preparation for prolonged blue-water operations rather than a short-duration sortie.
The PLAN currently operates three carriers: Liaoning (CV-16), Shandong (CV-17), and Fujian (CV-18), which commissioned in November 2025. Fujian is equipped with an Electromagnetic Aircraft Launch System (EMALS), making it China’s first catapult-equipped carrier and enabling the operation of heavier fixed-wing platforms, including the J-35 stealth fighter and KJ-600 airborne early warning aircraft — both of which completed carrier trials in 2025.
Operational and Strategic Context
The Liaoning group’s Western Pacific deployment follows a pattern of increasingly ambitious PLAN carrier operations. In June 2025, Liaoning became the first Chinese carrier confirmed by Japanese authorities to have crossed the second island chain, operating in waters near Minamitorishima, Japan’s easternmost island. That same month, Shandong (CV-17) was simultaneously confirmed operating in the Pacific Ocean — the first time two PLAN carriers had been observed conducting concurrent Western Pacific deployments.
The Liaoning group’s current deployment was pre-announced by Chinese state media on May 19, framed as a routine training exercise. The timing coincides with a period of elevated U.S.-Japan and U.S.-Philippines joint exercise activity in the region, including the annual Balikatan exercises.
In December 2025, during a previous Liaoning Pacific deployment, PLAN J-15 carrier-based fighters conducted repeated fire-control radar illuminations of JASDF F-15s during intercept operations — an episode that drew a formal protest from Tokyo.
For the JMSDF and U.S. Indo-Pacific Command, the operational integration of the Type 054B into carrier strike group missions — less than five months after the lead ship commissioned — indicates a compression of the PLAN’s platform-to-fleet-integration timelines that will have implications for regional force planning.
