## Summary

[China](/es/entity/china) ran what trade outlets call its first autonomous maritime [drone
swarm](/es/entity/drone-swarms) drill on 25 March 2026 off Zhuhai, using L30 [unmanned surface
vessels](/es/entity/naval-drones) that navigated, detected and "contained" a simulated intruder with limited
operator input after launch — redistributing positions to form a containment pattern. It
fits a broader Chinese push to fuse surface, aerial and underwater unmanned systems into
one network explicitly aimed at countering future [US Navy](/es/entity/us-navy) operations. Beijing
simultaneously unveiled new shipboard laser and missile defences against drone swarms,
hedging both sides of the technology. An earlier PLA reveal showed a 200-drone aerial swarm
run by one soldier, cooperating autonomously even after losing the operator link. The drill
is the maritime mirror of the US [Swarm Forge](/es/n/pentagon-swarm-forge-crucible) effort — and
a [Taiwan](/es/entity/taiwan)-contingency signal.

## By the numbers

- 25 March 2026 — Zhuhai L30 USV swarm drill.
- 200 — drones in the earlier PLA aerial swarm run by a single operator.
- 3 — domains China is fusing (surface, air, underwater) into one unmanned network.
- 2 — sides hedged: fielding swarms and unveiling laser/missile counter-swarm defences.

## Why it matters

The drill signals [China](/es/entity/china) can field coordinated, autonomy-led naval swarms in its near
seas — directly relevant to a [Taiwan](/es/entity/taiwan) blockade or anti-access fight against the
[US Navy](/es/entity/us-navy). Pairing offensive swarms with counter-swarm ship defences shows Beijing
preparing for a two-way drone war at sea, intensifying the US-China autonomy race.

## What to watch

- Scale and armament of follow-on L30 swarm exercises near Taiwan or the South China Sea.
- Maturity of China's surface-air-underwater unmanned network integration.
- How US MUSV/Replicator timelines stack against China's fielding pace.

### Defence-trade naval reporting
- **Army Recognition** (France / Global, en) — Reports China's 25 March drill off Zhuhai with a swarm of L30 unmanned surface vessels that navigated, detected and contained a simulated intruder with limited operator input, framing it as part of an integrated unmanned network — surface, air and underwater — aimed at countering future US naval operations.

### China-focused / regional-security framing
- **South China Morning Post** (Hong Kong / China, zh) — Reports China's parallel unveiling of new naval defence systems — lasers and missiles to counter drone swarms — as Beijing both fields swarms and hardens its own ships against them, reading the dual move as recognition that USVs are reshaping war at sea around its near waters.

### Technology / capability scrutiny
- **Tom's Hardware** (United States, en) — Documents an earlier PLA reveal of a 200-strong aerial swarm controlled by one soldier, using an intelligent algorithm to let units cooperate autonomously even after losing operator communication — the doctrinal sibling to the maritime L30 drill and a marker of China's swarm-autonomy progress.
