Attack-21 Test Flight in Coordination with 076 Sichuan Ship Sea Trials: PLA's Unmanned Carrier Aviation Enters Systematic Verification Stage

On August 29, two videos that continuously surfaced on social media brought a very specific detail to light: the Attack-21 stealth drone was flying over Huludao, Liaoning, while almost simultaneously, the first ship of the 076 amphibious assault ship, the Sichuan, was entering the final stages of its sea trials. Looking at either one alone would only indicate an equipment progress update; however, viewing both together changes the meaning. The PLA is no longer verifying "whether this type of drone exists," but rather "whether the drone, catapult deck, amphibious platform, and command chain can work together."

First, the platform is not an ordinary amphibious ship

• The China Military Network disclosed at the launch and naming of the Sichuan that the ship has a full-load displacement of over 40,000 tons, features a dual-island design and a fully longitudinal flight deck, and the official confirmation of the application of electromagnetic catapult and arrestor technology.
• SCMP mentioned in its follow-up report in July that the flight deck of the Sichuan is approximately 250 meters long and 62 meters wide, with deck markings already completed, indicating that the focus of testing is shifting from power reliability to aviation operations.
• This means that the 076 is not a simple enlarged version of the 075, but rather a new platform that lies between traditional amphibious assault ships and light unmanned aircraft carriers.

What the Attack-21 Truly Changes is Not Stealth, but the Method of Deployment

Public information indicates that the Attack-21 can be seen as a carrier-based version of the Attack-11. The flying wing layout and stealth shape are certainly important, but I believe the more critical aspect is its integration into the electromagnetic catapult system. Traditional amphibious ships mainly rely on helicopters, which have limitations in range, speed, and penetration capability; if the 076 can stably launch fixed-wing stealth drones, its alert radius, reconnaissance distance for coastal firepower, and initial suppression capability will be significantly extended. In simple terms, the same amphibious ship, when equipped with helicopters, can only deliver landing forces to the doorstep, while with reusable stealth drones, it qualifies to first blind the opponent's eyes and fire points at the doorstep.

Why the Test Flight Location is Worth Noting

SCMP cited geographical positioning indicating that the relevant videos appeared around Huludao, Liaoning, at least twice on August 19 and this Thursday. This suggests that the project is likely still in the high-frequency flight envelope verification stage, rather than a symbolic appearance. The publicly available footage did not show catapult launches or landings, so there remains a threshold to "achieve combat capability," especially regarding onboard recovery, deck scheduling, data link anti-jamming, and continuous operational rates under sea conditions; these are the truly challenging parts. The outside world is currently prone to overestimating the significance of the first flight news while underestimating the lengthy series of less photogenic video projects that follow.

What the Combination Means for the Taiwan Strait and Far Sea Groupings

If the combination of the Sichuan and Attack-21 proves successful, the PLA Navy will gain a very practical intermediate capability: it will not have to push the most expensive aircraft carrier formations to the front lines, while still allowing amphibious groupings to carry a certain level of reconnaissance, electronic suppression, and first-strike capabilities. This is particularly sensitive for the Taiwan Strait direction, as the greatest fear in landing operations is not a lack of ships, but rather a breakdown in the intelligence chain and a short firepower window before engaging the enemy. If the 076 can push drones forward by dozens or even hundreds of nautical miles, it effectively adds a buffer zone of "seeing first, suppressing first, then approaching" to the landing group. Looking further afield, this also aligns with the increasingly evident thinking of the Chinese Navy in recent years: not every mission requires an aircraft carrier, but every group should strive to carry some degree of carrier-like aviation capability.

The Questions That Remain Unanswered

This line of inquiry is certainly important, but I am more interested in what comes next. Whether the Attack-21 can complete maritime electromagnetic catapult launches and recoveries will determine whether the 076 is merely a conceptually advanced demonstration ship or a practical platform that will rewrite the operational use of amphibious groupings. The stealth shape has already been revealed to the outside world; what has not yet been made public is how many sorties it can fly in a day, whether it can return stably at sea, and whether the PLA is willing to release these most critical images.
