2/23/2026, 10:54:17 PM

Testing of the 155mm Naval Gun

Recent developments indicate that Beijing is advancing its military capabilities with the testing of a new 155mm (6.1-inch) naval gun, aimed at enhancing the People’s Liberation Army Navy’s (PLAN) land-attack firepower. This weapon, which is expected to be the largest in the PLAN's arsenal, has been observed mounted on a test vessel at the Liaonan shipyard in Dalian, located in northeastern Liaoning province. The gun's barrel length and turret shape align with previous images of the 155mm naval gun under development by the China North Industries Group Corporation (Norinco), which was seen being transported by road last year.

Implications for Amphibious Operations

The introduction of the 155mm naval gun is particularly significant for potential amphibious operations, especially concerning Taiwan. The weapon's capability to fire guided munitions and its substantial weight of approximately 21.8 tonnes suggest a considerable enhancement in the PLAN's offensive capabilities. Once operational, this gun will represent a notable upgrade in the main gun caliber among modern navies, potentially altering the balance of power in regional maritime operations.

Official Statements & Responses

While the Chinese government has not issued specific statements regarding the operational timeline for the 155mm naval gun, military analysts suggest that its deployment could be indicative of a broader strategy to bolster China's amphibious assault capabilities. This aligns with China's ongoing military modernization efforts aimed at asserting its influence in the Asia-Pacific region.

Criticism & Opposition

Critics of China's military expansion express concerns that the development of such advanced weaponry could escalate tensions in the region, particularly with Taiwan and neighboring countries. Analysts warn that the enhanced firepower may provoke an arms race, as other nations may feel compelled to respond to China's growing military capabilities.

Conflicting Reports & Gaps

There is limited information regarding the specific timeline for the 155mm naval gun's operational readiness and its integration into the PLAN's existing fleet. Additionally, while some sources highlight the potential for guided munitions, details on the types of munitions and their effectiveness remain unclear.
