China’s navy has added two more Type 055 class destroyers to its Eastern Theater fleet, commissioning hulls 109 Dongguan and 110 Anqing and immediately sending them into the East China Sea for intensive, realistic training. The vessels carried out single-ship drills — including confined-water navigation and damage control — before joining a task group to practice anti-surface strikes, underway replenishment and multi‑domain coordination.
The Type 055 is Beijing’s largest surface combatant class to date: a roughly 10,000‑tonne “big destroyer” built around an advanced radar suite, a universal vertical launch system and integrated radio-frequency sensors. Chinese state media and naval statements portray the class as a carrier strike group escort and a core asset for distant-sea operations; the easternfleet postings of the new hulls underscore a focus on the East China Sea and areas adjacent to Taiwan.
The recent exercises placed emphasis on anti‑submarine warfare. The task group launched ASW helicopters that worked with surface ships to build an air‑sea anti‑submarine network, using a shared command information system to link platforms and exchange data in real time. Officers said the drills were conducted against a realistic distant‑sea combat backdrop to test ship‑helicopter coordination and to address typical limits of single‑platform ASW operations.
The raft of drills — anti‑surface strike, replenishment at sea, information networking and integrated ASW — indicate Beijing is not only expanding its fleet but accelerating the operationalisation of high‑end platforms. For a navy that has focused heavily on shipbuilding in the past decade, turning new hulls into fully capable units able to fight as part of a joint, distributed task force is the next, decisive step.
Stationing these new 055s in the Eastern Theater has immediate regional implications. The East China Sea is a strategic theatre where Chinese, Japanese and U.S. naval interests frequently converge, and enhanced PLA capabilities there amplify Beijing’s capacity to shape local naval balances. Improved ASW reach and networked command will complicate allied submariner and antisurface operations and is likely to draw renewed emphasis from U.S. and partner navies on anti‑access countermeasures and layered sensor architectures.
Despite the progress signalled by these drills, significant practical challenges remain for the PLAN. Effective long‑range power projection depends on logistics, replenishment, sustained maintenance cycles and the maturation of joint command-and-control procedures — areas that historically lag behind megaship construction. The recent exercises show the PLAN is prioritising those gaps, but operational experience, particularly under contested conditions and against capable adversaries, will be the ultimate test.
For the broader military balance in the Indo‑Pacific, the commissioning and rapid training of the 109 and 110 hulls mark incremental but meaningful advances in China’s blue‑water naval capabilities. The trend will likely prompt closer allied coordination on ASW, heightened surveillance of eastern Chinese waters, and more frequent freedom‑of‑navigation and presence operations to monitor the PLAN’s growing reach.
