The Navy of the Chinese People’s Liberation Army (PLAN) once again demonstrated that it continues to advance in the incorporation of new technological capabilities for its Type 054B stealth frigates, which would integrate artificial intelligence (AI) to improve their air defense capabilities. These units incorporate a new-generation architecture that makes it possible to optimize detection and response against aerial threats.
One of the most notable aspects of the Chinese Navy’s Type 054B frigate — such as the Luohe (545) — is the use of advanced algorithms supported by artificial intelligence, which would make it possible to significantly reduce or even eliminate blind spots in air defense, improving the effectiveness of combat systems in complex scenarios.
This new architecture is complemented by its optimized command system, with a more “flat” structure that facilitates interaction between operators and weapon systems, allowing faster and more efficient decision-making during operations. At the same time, the frigate features improvements in its stealth design, with integrated sensors and antennas that reduce its radar signature, as well as greater efficiency in propulsion and operational endurance.
In terms of capabilities, the Type 054B frigates are conceived as multipurpose platforms, capable of carrying out air defense, anti-submarine warfare, and escort missions for larger units, such as aircraft carriers or amphibious ships. In recent exercises, these frigates have operated alongside Type 055 and Type 052D destroyers, highlighting their role as a protective complement within naval task groups.
Likewise, during Chinese Navy training activities, their role in high-intensity scenarios has been emphasized, including simulated torpedo attack situations, in which the crew carried out maneuvers to place themselves between the threat and higher-value units, reaffirming their function as the “last line of defense” within the formation.
Lastly, it should be mentioned that the Type 054B frigates represent a direct evolution of the Type 054A, incorporating greater displacement — around 5,000 tons — and improvements in sensors, combat systems, and technological integration. These characteristics allow them to operate in deep-water environments and take part in power projection missions beyond the littoral, supporting the expansion of the Chinese Navy toward “blue-water” capabilities.
