BEIJING, — June 20, 2026 : Newly released high-resolution satellite imagery captured on June 19 shows the Chinese People’s Liberation Army Navy (PLAN) aircraft carrier Shandong (CV-17) continuing an extended maintenance period at Yulin Naval Base on Hainan Island. The carrier has remained in dry dock since January 20, 2026, marking approximately five months of continuous maintenance work.
The images confirm that the Type 002 aircraft carrier, China’s first domestically built carrier, remains positioned inside Yulin’s large carrier-capable dry dock. The prolonged maintenance period highlights the PLAN’s growing ability to conduct major carrier overhauls and sustainment activities at facilities located in the South China Sea rather than relying exclusively on northern shipyards.
Dry Dock Activity and Supporting Vessels
Satellite imagery of the naval complex in Sanya provides a detailed view of the maintenance operation. Shandong remains stationed inside the primary dry dock, which was specifically designed to accommodate large naval vessels, including aircraft carriers.
A secondary dry dock located adjacent to the carrier facility has been completely drained of water and was empty at the time the imagery was taken.
Several important naval assets were also observed at nearby berths supporting the maintenance effort. Among them was Integrated Support Ship Forward 2 (Hull 89), a Daguan-class (Type 032) auxiliary vessel commonly used to provide accommodation, logistics, and technical support for carrier crews and maintenance personnel during extended repair periods.
Also berthed nearby was a Type 055 guided-missile destroyer, one of the PLAN’s most advanced surface combatants. Displacing approximately 13,000 tons and equipped with 112 vertical launch cells, the Type 055 serves as a key escort vessel within Chinese carrier strike groups and represents a significant concentration of naval capability at the southern base.
First Carrier Maintenance at Yulin’s Purpose-Built Facility
The ongoing work represents the first known use of Yulin’s purpose-built carrier dry dock for a Chinese aircraft carrier. Construction of the facility began in 2017 and was completed around 2022 as part of broader efforts to expand naval infrastructure on Hainan Island.
Measuring roughly 370–375 meters in length, the dock is capable of accommodating vessels significantly larger than the 304.5-meter-long Shandong. Until now, major carrier maintenance and overhaul work for China’s aircraft carriers had largely been conducted at the Dalian Shipyard in northern China, where both Liaoning and Shandong were originally built.
The availability of a southern maintenance facility allows the PLAN to service aircraft carriers much closer to their primary operating areas in the South China Sea. This reduces transit requirements and improves the navy’s ability to maintain operational readiness in strategically important waters.
Scope of Maintenance
The exact nature of the work being performed on Shandong has not been officially disclosed. However, comprehensive carrier maintenance periods of this duration typically involve extensive inspections and refurbishment activities.
Such work may include hull cleaning and repairs, propulsion system inspections, maintenance of arresting gear and aircraft handling equipment, flight deck resurfacing, sensor servicing, and upgrades to onboard systems. Earlier satellite imagery from February 2026 showed visible activity on the flight deck, including the removal of deck markings, suggesting ongoing refurbishment efforts.
Analysts have also noted recent reports in Chinese state media regarding efforts to integrate the new J-35 fifth-generation stealth fighter into the air wings of existing carriers, including Liaoning and Shandong. Extended dry-dock periods can provide opportunities for deck modifications and system adjustments needed to support new aircraft types.
Expanding Carrier Sustainment Capabilities
Commissioned in December 2019, Shandong serves as the PLAN’s second aircraft carrier and its first domestically built carrier. The vessel has participated in numerous training exercises and deployments across the South China Sea and the western Pacific since entering service.
The use of Yulin Naval Base for long-term carrier maintenance is viewed as a significant step in expanding China’s carrier sustainment infrastructure. By conducting major maintenance closer to operational theaters, the PLAN can reduce dependence on northern shipyards and improve fleet availability.
China currently operates three aircraft carriers—Liaoning, Shandong, and Fujian—while reports indicate that a fourth, nuclear-powered carrier is under development. As the carrier fleet expands, facilities such as the Yulin dry dock are expected to play an increasingly important role in supporting maintenance, repairs, and long-term operational readiness.
While the timeline for Shandong’s return to sea remains unclear, satellite imagery indicates that maintenance work continues at the Hainan facility. Observers are expected to monitor future imagery for indications that the carrier is preparing to undock and begin post-maintenance sea trials.
