Longtime People’s Liberation Army (PLA) researcher Ken Allen has produced an extraordinary compilation of PRC sources detailing the PLA Navy (PLAN) and its activities in 2025. The information was compiled for a project sponsored by Exovera and the simplified data were published for January through July.[1]

Taken together, the corpus constitutes an unusually substantial, chronologically organized collection of official and quasi-official PRC open-source reporting on the PLA Navy during calendar year 2025. The set has three layers: a 209-page overview/index; a 277-page collection preserving the English-language articles themselves; and a 1,295-page collection preserving the Chinese-language articles, generally together with machine translations. The overview identifies the principal source streams as the English-language Ministry of National Defense (MND) and China Military Online sites and several Chinese-language PLA/MND channels. More importantly, it provides a chronological research map: 279 English-language items, followed by 377 Chinese-language items, for 656 indexed items in all. The English sequence ends with item 279 on 30 December, while the Chinese sequence begins with item 280 and ends with item 656. This makes the overview much more than a table of contents: its short descriptions, dates, source citations, hull numbers, exercise details, and notes on photographs and videos make it a searchable analytical index to the two much larger source collections.

What the corpus contains is strikingly broad. At the most visible operational level, it documents fleet training, carrier aviation, submarines, amphibious operations, replenishment and logistics, naval aviation, search and rescue, escort operations, overseas deployments, military diplomacy, hospital-ship missions, port visits, and multinational exercises. Even routine English-language reporting often supplies specific hull numbers, platform types, dates, locations, and activity descriptions—for example, the compilation records J-15 sorties lasting from 0800 to 2100 and identifies the Type 903A replenishment ship Kekexilihu by hull number, assignment, and previous Gulf of Aden and foreign-exercise experience. Other entries capture activities that are easy to overlook in more strategic reporting: emergency rescue, towing and salvage, medical evacuation, combat-support training, air-defense and antisubmarine drills, ammunition and damage-control activities, and Maritime Safety Administration exclusion notices. The English collection is particularly rich in visual evidence—photographs and links to short videos whose captions identify ships, aircraft, subordinate organizations, training evolutions, and occasionally otherwise obscure equipment. The overview systematically flags these materials rather than merely noting that an article existed; an example is its description of aviation, replenishment, and student-navigation material, including a 16-day, 3,000-nautical-mile training voyage with 24-hour watch rotations.

The Chinese-language collection is considerably more revealing at the organizational, institutional, and human level. Its articles routinely go beneath the platform-and-exercise layer to describe how units train, diagnose deficiencies, maintain equipment, educate personnel, restructure organizations, develop specialists, conduct political work, support families, and adapt training methods. One January example describes a destroyer formation integrating ships, shipborne helicopters, and shore-based antisubmarine patrol aircraft into a common antisubmarine training system and explicitly emphasizes “system support” and coordinated victory. Another describes the deliberately economical “one ship at sea, multiple ships strengthening capabilities” model, under which personnel from several ships train aboard one vessel and then link up with submarines and aircraft for air-defense, penetration, and joint-ASW training. Elsewhere, the collection describes integrated maintenance command centers using aircraft-status monitoring, resource management, data sharing, algorithms, and IoT devices to replace a maintenance model dependent on individual technicians’ experience. Still other articles expose persistent difficulties—skills bottlenecks, equipment failures that cannot initially be repaired at sea, gaps caused by personnel turnover, excessive reliance on scripted training, and problems integrating specialists—while explaining the unit-level solutions being attempted.

That contrast between the two language streams is one of the collection’s greatest analytical values. The English material is disproportionately useful for reconstructing what the PLAN wants foreign audiences to see: named platforms, deployments, bilateral and multilateral engagements, overseas presence, humanitarian activities, new equipment milestones, visually compelling training, and official statements about Chinese intentions. A representative English report identifies the warships Baotou and Gaoyouhu by name and hull number and specifies replenishment, anti-piracy, search-and-rescue, and air-defense subjects for AMAN-2025. By contrast, the Chinese material frequently tells researchers much more about how the force is attempting to generate combat effectiveness—through training pedagogy, command relationships, Party organization, personnel development, equipment support, troubleshooting, cross-specialty learning, implementing lessons learned, and recognizing shortcomings. For example, a submarine-training account describes the conscious breakdown of occupational barriers and cross-disciplinary training so that a radar operator could perform emergency damage-control work while the sonar operator remained on the tactical problem. This asymmetry itself is analytically significant: comparing Chinese- and English-language coverage can help distinguish external strategic messaging from internal professional discourse.

Taken longitudinally, the compilations reveal a PLAN that in 2025 was concerned not simply with acquiring more sophisticated hardware but also with making a larger, technologically more complicated fleet operationally coherent. Repeated themes include system-of-systems integration, jointness, realistic and adversarial training, transition from individual proficiency to crew and formation proficiency, cross-specialty competence, night and all-weather operations, logistics under combat conditions, autonomous maintenance and repair, and the identification of weaknesses through exercises. A late-year submarine-training account explicitly contrasts isolated skill proficiency with coordination across the entire boat and describes connecting formerly separate simulators so different specialties can train together against realistic offensive and defensive scenarios. Another Chinese article characterizes the underlying objective as moving professional training from mere “physical combination” toward “chemical integration,” with “jointness” and research as central concepts. Such material is particularly valuable because official propaganda normally emphasizes success, yet these articles often disclose the problem(s) that preceded the success story. Read critically, those acknowledged problems can be more informative than the asserted solution.

The collection also provides an unusually detailed contemporaneous record of major capability transitions during a consequential year for PLAN modernization. The aircraft carrier Fujian appears repeatedly across both language streams as it moved through testing, electromagnetic catapult operations, commissioning, and initial formation training. The English collection records the September announcement that the J-15T, J-35, and KJ-600 had completed their first electromagnetic catapult-assisted launches and arrested recoveries aboard Fujian. The Chinese collection subsequently documents Fujian’s 5 November commissioning and spells out the claimed operational significance of catapult launch for aircraft payload, fixed-wing airborne early warning, command and control, and a more diverse air wing. The overview then captures its first post-commissioning live-force training, including formation navigation, ship-air search and rescue, and launches and recoveries by J-35, J-15T, J-15DT, and KJ-600 aircraft. The virtue of the compilation is therefore not simply that it contains individual Fujian-related stories; it allows researchers to reconstruct the sequence and maturation of a capability across an entire year.

For researchers, the strongest way to exploit the set would be to treat the Overview as the discovery layer and the two article compilations as the evidentiary layer. Start by searching the overview for a platform, unit, fleet, exercise, mission type, geographic area, or operational concept—Fujian, Type 055, submarine, antisubmarine, replenishment, “system,” Gulf of Aden, South China Sea, amphibious, maintenance, political rectification, and so forth. Build a chronology from its numbered entries, then move to the corresponding full articles. For consequential propositions, researchers should return to the original Chinese text, using the included Google translation for discovery and triage rather than as an authoritative translation; the Chinese compilation explicitly places machine-translated English beneath the source text, as visible from its opening article. Technical vocabulary—especially terms such as zhidui, system-of-systems concepts, combat-readiness terminology, Party organizational terminology, and expressions concerning training and operational art—should be translated directly from the Chinese before publication.

A second, more powerful use would be to turn the corpus into a structured longitudinal dataset. Each of the 656 overview records could be coded for date, source, language, theater command, named unit, ship or aircraft type, hull number, geographic location, mission category, training subject, joint/foreign participant, readiness issue, personnel issue, logistics or maintenance issue, and whether the item includes imagery or video. Researchers could then identify patterns that disappear when articles are read individually: which fleets discuss particular training problems most frequently; whether certain readiness concepts rise or fall during the year; which ships can be associated with particular flotillas; how often overseas deployments are coupled with training; or how the publicity surrounding a new platform changes as it progresses from trials to operational employment. The corpus is especially well suited to entity resolution and order-of-battle research because apparently mundane captions repeatedly provide combinations of hull number, ship name, subordinate formation, theater command, date, and location. It could likewise support careful studies of training evolution, maintenance systems, personnel policy, political work, and combat-support architecture—subjects for which PRC reporting is often far richer than conventional Western reporting.

Finally, the collection should be used with an explicit source-critical methodology. It is not a neutral operational log and not a comprehensive record of everything the PLAN did in 2025. It is rather a compilation of what selected PRC official media chose to publish. Absence therefore cannot safely be treated as evidence that an activity did not occur, and claims of extraordinary performance require independent corroboration. At the same time, propaganda content should not be dismissed as analytically worthless. Recurring emphases, admitted shortcomings, changes in terminology, details embedded in captions, named organizations, equipment associations, training scenarios, and discrepancies between Chinese- and English-language presentation can all yield high-confidence findings when triangulated. The corpus’s distinctive value is precisely this combination of breadth, chronology, preservation of original Chinese text, parallel English publicity, detailed indexing, visual material, and thousands of granular observations about the PLAN at work. Used comparatively and longitudinally rather than as a stack of isolated articles, it is a genuinely unusual research resource for reconstructing both what China’s Navy was doing in 2025 and how the institution itself described the problems, processes, and priorities involved in becoming a more capable fighting force.

It is important to know not only what the articles say about the PLAN but also what they do not say. Specifically, there is not a single reference to any of the PLA’s 15 grades. The only reference to officer ranks is to various Naval spokespersons, and the focus is on units at the Theater Command Navy level, not at PLAN Headquarters level. There is also no information about the two-cycle conscription process, which clearly impacts the annual training cycle.
