China Builds Potentially the World’s Largest Naval Replenishment Ship

Core Development at the COMEC/GSI Yard
A massive auxiliary vessel is under construction at the China State Shipbuilding Corporation (CSSC) offshore subsidiary, the CSSC Offshore and Marine Engineering Company (COMEC), on Longxue Island southeast of Guangzhou. Satellite imagery from Planet Labs shows the hull in place since at least February 2024, with a July 2 2026 image revealing a forward superstructure with a wide bridge, a rear superstructure housing exhaust stacks, and a large flight-deck-and-hangar complex at the stern. Pillar-like vertical structures amidships suggest the ship will conduct underway refueling and replenishment.
Background & Context
China’s People’s Liberation Army Navy (PLAN) has expanded its carrier force with the conventionally-powered carriers *Liaoning* and *Shandong*. Sustained blue-water operations for these platforms require a robust at-sea logistics chain. Existing Type 901 replenishment ships already support carrier strike groups, but the new hull appears to be a substantially up-scaled version, reflecting the PLAN’s ambition to operate farther from Chinese ports and to support a growing fleet of amphibious assault ships such as the Type 076 *Sichuan*.
Design Features & Scale
The vessel’s hull is “broad and slab-sided, with a full midsection optimised for volume rather than speed alone,” a description from a Jane’s report. Its dimensions exceed the 787-foot (240 m) length and 102-foot (31 m) beam of the Type 901, surpassing the U.S. Navy’s 746-foot (227 m) John Lewis-class oilers. Dual hangar doors and large side apertures could accommodate helicopter vertical replenishment and small-boat operations. Armament details remain undisclosed; the Type 901 carries four 30 mm H/PJ-13 Gatling guns for close-in defense.
Strategic Implications
The ship’s enlarged fuel, munitions, spare-parts, and provisions capacity would enable PLAN carrier groups to remain on station for extended periods, reducing reliance on foreign ports that may be unavailable during conflict. Analysts note that the United States faces its own logistical challenges, as highlighted by recent U.S. Navy experiences in the Middle East where port access was disrupted by Iranian actions.
Official Statements & Responses
- Jane’s analysis emphasizes the vessel’s volume-focused hull form as characteristic of large fleet auxiliaries.
- Robert Hein, Director of Maritime Operations for the U.S. Navy’s Military Sealift Command, observed that “for 25 years, we’ve been at war in the Middle East and that war was effectively fought in the parking lot of a giant gas station,” underscoring the strategic value of at-sea replenishment.
- Chinese state media describe the ship as “very much like a Type 901, but substantially scaled up,” reinforcing its intended role as a flagship logistics platform.
Criticism & Opposition
Open-source assessments note the absence of confirmed defensive weaponry, raising questions about the ship’s survivability in contested environments. The lack of an official displacement figure also fuels speculation about its true capabilities.
On-the-Ground Satellite Evidence
Planet Labs images from February 2024 onward show progressive construction, while the July 2 2026 view captures the dual superstructures, large rear hangar, and mid-ship pillar arrays typical of underway replenishment vessels.
Conflicting Reports & Gaps
- No definitive tonnage has been released; estimates range from the Type 901’s 45,000 tons to a larger, unspecified figure.
- Armament specifications remain unknown, leaving the ship’s self-defence posture uncertain.
Verbatim Quotes
- “The hull form is broad and slab-sided, with a full midsection optimised for volume rather than speed alone. This is a characteristic associated with large fleet auxiliaries designed to carry fuel, dry stores, and ammunition for carrier strike groups,” — Jane’s report, April 2024
- “So traditionally, for 25 years, we’ve been at war in the Middle East and that war was effectively fought in the parking lot of a giant gas station,” — Robert Hein, Director of Maritime Operations, U.S. Navy Military Sealift Command
The vessel’s completion, anticipated later in 2026, will likely reshape the logistical balance of naval power in the Indo-Pacific, offering the PLAN a decisive sustainment advantage for its expanding carrier and amphibious forces.
