“->It took 25 months for the first 054B from block erection to commission.
->It took 24 months for the first Mogami for the same process.

Also note that the 054B has significant firepower with 32 VLS while the first Mogami has no VLS fitted when it was constructed.

So the 054B should have been built faster than JS Mogami if we add VLS to Mogami as well.”
 
Construction of new 4x Type-054B FFG to begin
- Type-054A FFG modernizations continue
- Construction of new 6 supply ships to be built
 
The latest improved version of the Type 054A frigate has begun sea trials. (Possibly codenamed "Type 054AG")
The most significant difference is the longer helicopter deck at the stern. The bow main gun was changed from a 76MM naval gun (Type H/PJ-26) to a 100MM naval gun (Type H/PJ-87).

good looking ship.
Strange they didn'install a 4 arrays radar instead of this one.
i mean, with beam steering up to 60 degrees off angle the blind spot will be minor

The PLA Navy's requirements for the Type 054A frigate are:
1. Low cost. Large-scale construction is possible. Economic factors are its core considerations.
2. Multiple routine missions. These include anti-submarine warfare, medium-range air defense, patrol surveillance, and escort. It does not undertake the core air defense command mission, which is handled by other ships in the fleet (Type 052D/055).

The cost of a Type 054A frigate is approximately 1.4 to 2 billion RMB (depending on the batch and version). However, the cost of a large phased array radar for the Type 054A frigate is approximately 500 million RMB. This clearly does not align with the Type 054A's requirements.

The latest Type 054B frigate is equipped with an S+X dual-band large double-sided array radar. However, the Type 054A frigate is still under construction. This shows that the two warships have different tactical positioning.

I cannot tell the difference.
 
Hint 1:
Their main guns at the bow are different.

For other details, please observe carefully yourself.
From what is visible, they appear to be small changes. Nothing major. Of course, what is hidden is hidden.

The People’s Liberation Army Navy (PLAN) has announced the commissioning of a new Type 054A guided-missile frigate. Named Linfen and bearing hull number “543,” the vessel represents an improved version of the class, confirming the continued maturation of the platform and the introduction of upgrades to one of the most numerous surface combatant and escort classes within the Chinese Navy. The entry into service of this new ship demonstrates that, despite the development and introduction of the more advanced Type 054B class, Chinese naval leadership continues to invest in the evolution of the Type 054A design to meet the increasingly broad requirements of the Asian giant in the naval domain, amid a growing number of deployments across the Indo-Pacific and beyond.

According to information released by official Chinese sources, Linfen corresponds to a new variant of the Type 054A frigates, developed and built independently by China’s naval industry. At first glance, one of the most significant modifications compared to the original units is the extension of the flight deck and hangar, along with an increase in the ship’s length. This allows the operation of larger and more complex embarked helicopters, such as the anti-submarine version of the Z-20, replacing the lighter Z-9 currently in use.

Improvements in anti-submarine warfare capabilities and embarked aviation​

The enlargement of the flight deck and hangar would address one of the main limitations identified in the early versions of the Type 054A: its helicopter-based anti-submarine warfare capability. The introduction of the Z-20F—along with the new utility version Z-20J, featuring greater range, endurance, and more advanced sensors—would enable the detection and engagement of submarines at longer distances than those achievable with helicopters previously operated from the frigate.

Main armament​

Another visible improvement is the adoption of a main gun of larger caliber, presumably 100 mm, similar in appearance to that fitted on the new Type 054B frigates. According to China Central Television (CCTV), this weapon provides greater firepower, longer effective range, and higher accuracy, enhancing anti-surface combat capabilities and naval gunfire support, as well as enabling limited strike missions against land targets.

These modifications are complemented by the integration of a more unified weapons system, along with upgrades to sensors, radars, and fire-control systems. This would allow for extended detection ranges, improved target localization accuracy, and more effective operation in complex electromagnetic environments—an increasingly relevant factor in modern warfare scenarios.

Other aspects​

Likewise, according to official reports, the new variant would also feature improvements in radar signature reduction and stealth characteristics, contributing to lower detectability by adversary sensors. All of this would enhance the ship’s survivability in high-intensity scenarios, particularly during escort operations and the protection of maritime routes.

Meanwhile, the commissioning of this improved frigate takes place in parallel with the progress of the Type 054B program, a class of greater displacement and capabilities, of which the Chinese Navy has already commissioned two units. Nevertheless, observers suggest that this does not imply a replacement of the Type 054A, but rather that both classes will operate in a complementary manner.

China Gets More Warships as US Waits on New Frigate


PUBLISHED
JAN 13, 2026 AT 03:07 AM EST

China continues to expand its fast-growing navy—already the world's largest by hull count—as it fielded a new frigate, state media reported on Monday, a type of vessel the United States, its military rival, is expected to introduce as early as 2028.

China Central Television reported that CNS Linfen, a new variant of the Type 054A frigate with a more powerful naval gun and expanded aviation facilities for helicopters, has been commissioned into service with the People's Liberation Army (PLA) Navy.

Newsweek has contacted the Chinese Foreign Ministry for further comment by email.

Why It Matters​

As part of its vision to build a "world-class" military, China is undergoing rapid naval modernization through advances in shipbuilding and force projection, resulting in over 370 vessels in operation and an expanded military reach across the western Pacific.

Among the Chinese military's fleet of warships are more than 40 ships in the Type 054 frigate family across four variants—the Type 054, Type 054A, Type 054AG and Type 054B—often deployed on long-range missions with aircraft carriers or as part of escort task groups.

Meanwhile, the U.S. Navy plans to field President Donald Trump's battleship-centered fleet, including a new design based on a Coast Guard cutter to replace the canceled Constellation-class frigate program, with the first hull expected to launch in two years.

What To Know​

Unlike the Type 054A frigate variant, the Linfen is designed with a longer flight deck and an expanded hangar to accommodate the newer, larger Z-20 helicopter, which provides improved submarine hunting capabilities, China Central Television reported.

According to Alex Luck, an Australia-based naval analyst, the improved Type 054A frigate variant is officially designated the Type 054AG. Another feature is a larger-caliber main gun, replacing the original 76 mm gun with a 100 mm gun on the bow.

Gong Chao, a crew member of the Linfen, told China Central Television that the gun has an extended range and improved precision for anti-surface warfare strikes, while the ship's radar detects targets at longer distances with "higher positioning accuracy."

China Central Television footage shows the Linfen, hull number 543, moored alongside another frigate with hull number 580. The Global Times reported that the second ship, equipped with the same gun as the Linfen, was likely another new Type 054AG vessel.

A Japan-based Chinese military observer on the social media platform X, type36512, noted that the Linfen is part of the sixth shipbuilding batch of Type 054A/AG frigates and that the total number of Type 054A/AG variants planned is estimated at around 50.

Each 4,000-ton Type 054A frigate and its improved variant is equipped with a 32-cell vertical launching system for anti-air missiles, eight launchers for anti-ship missiles, two triple torpedo launchers and two close-in weapon systems, Naval News reported.

The commissioning of new Type 054AG frigates comes after two Type 054B vessels—displacing 5,000 tons and designed with stealth features—entered service last year, but there are no indications that additional hulls of the type are being built, Luck said.

"This has led some observers to speculate [Type 054B] is not an acceptable design for [People's Liberation Army Navy]," Luck wrote for Naval News earlier this month, noting the continued production of the Type 054A frigate in its improved variant.

What People Are Saying​

Quoting Chinese military expert Zhang Junshe, Global Times reported: "The larger main gun can boost the new Type 054A's multirole capabilities, for example, capabilities in close-range maritime combat and land attack. The upgraded radar systems, on the other hand, contribute to the vessel's air defense capabilities."

Alex Luck, an Australia-based naval analyst, wrote for Naval News: "It is important to point out that [People's Liberation Army Navy] is typically conservative in adaption of new warship designs. Validation and induction of new warships takes time, while the shipyards have a preference for continued production. The Chinese Navy also evidently still pursues a course of further rapid growth and modernization."

What Happens Next​

It remains to be seen whether China will resume construction of additional Type 054B frigates this year or build both them and the Type 054AG variant concurrently as part of efforts to expand its navy following the U.S. unveiling of its "Golden Fleet" plan.
