Trial by fire: Chinese laser weapon reputedly in Russian service

China’s battlefield lasers have arrived in Ukraine and may soon shape a drone-saturated future war over Taiwan.

Last month, The War Zone (TWZ) reported that Russia has reportedly deployed a Chinese laser weapon system to counter Ukrainian drones, according to pro-Russian Telegram sources.

A video posted this May shows a system resembling China’s Shen Nung 3000/5000 anti-drone laser, previously supplied to Iran.

The footage depicts Russian troops operating the system from a vehicle, followed by its deployment and engagement of aerial targets, including drones visibly catching fire midair.

The Nomad special forces unit is reportedly utilizing the system, with Russian analysts deeming it a significant advancement over previous counter-drone technologies.

While the exact specifications remain unclear, experts suggest that the system is a variant of the Low-Altitude Laser Defending System (LASS) manufactured by China’s Academy of Engineering Physics.

The incident underscores deepening military cooperation between Russia, China and Iran, raising concerns over China’s expanding arms exports amid ongoing conflicts. China has denied direct involvement and claims neutrality.

The video’s emergence comes amid broader developments in laser air defense technology, including Israel’s Iron Beam system, deployed against Hezbollah drones.

The effectiveness of laser-based weapons remains debated due to environmental limitations and operational challenges, but their increasing field use signals ongoing adaptation in modern warfare.

Looking at the promise of laser weapons, Ian Boyd mentions in a March 2024 article for The Conversation that laser weapons promise speed-of-light engagement, precision targeting, and an “infinite magazine” as long as power is available.

Boyd highlights their advantages, including low cost per shot, minimal logistical footprint, and adaptability across land, sea, air, and space platforms. However, he also points out their drawbacks, such as high power demands, cooling requirements and environmental limitations, including fog, rain and smoke.

Those advantages could have been decisive in US operations against Houthi rebels in the Red Sea. Lara Seligman and Matt Berg note in a December 2023 Politico article that the US has used multi-million, hard-to-replace interceptor missiles to intercept Houthi suicide drones that cost US$20,000 at most.

In that situation, they point out that the cost-benefit analysis favors the Houthis, with high interceptor missile costs, long missile production times and limited ship magazines all working against the US.

Further, laser weapons might have mitigated some of the damage in Ukraine’s recent audacious drone swarm attack on Russian airfields and bombers.

While Russia deployed countermeasures, such as blast walls, decoys, air defense systems and improvised defenses, including placing tires on bomber wings to confuse image-matching systems, these have yielded mixed results at best.

Building hardened aircraft shelters (HAS) may not have been an option for Russia, given the size of its bomber aircraft, and that doing so could spark a nuclear miscalculation between the US and Russia.

While Russia has suspended its participation in the New Strategic Arms Reduction Treaty (START 3), it still complies with its terms in practice by keeping its bombers out in the open, allowing for US satellite and inspection-based verification.

While US airbases in the Pacific lack hardening, the US hardening its airbases could be interpreted by Russia or China as preparation for nuclear war or a more aggressive nuclear posture, with negative implications for strategic stability.

Lessons learned from the Russia-Ukraine War could inform China’s doctrine in deploying laser weapons during a Taiwan Strait conflict.

Highlighting the possibility of drone swarms being used against China, US Indo-Pacific Command (USINDOPACOM) commander Admiral Samuel Paparo said in a July 2024 Washington Post interview that he intends to turn the Taiwan Strait into an unmanned “hellscape” to deter a Chinese invasion of Taiwan.

“I want to turn the Taiwan Strait into an unmanned hellscape using a number of classified capabilities,” he said. “So that I can make their lives utterly miserable for a month, which buys me the time for the rest of everything.”

According to USNI News in January 2025, the US Department of Defense’s (DOD) Replicator initiative is advancing toward its August 2025 milestone, aiming to deploy lethal swarms of unmanned vehicles linked by integrated software.

The report states that the first tranche of the Replicator initiative, initially launched in 2023, focuses on surface and subsurface drones and loitering munitions to deter a potential Chinese invasion of Taiwan. It says that the second tranche, announced in 2024, prioritizes counter-drone capabilities.

As to how the US could use Replicator drone swarms to defeat a Chinese invasion of Taiwan, Stacie Pettyjohn and other writers mention in a June 2024 Center for a New American Security (CNAS) report that swarms of low-cost, long-range suicide drones can overwhelm Chinese naval forces and disrupt amphibious landings.

Pettyjohn and others say that these autonomous systems when paired with advanced surveillance drones, would rapidly close kill chains by identifying targets and guiding precision strikes. They add that pre-positioned drones in Taiwan could accelerate early response, while layered counter-drone defenses would blunt China’s swarms.

A January 2025 Defense News report stated that while the Replicator initiative has received bipartisan support, concerns persist over funding, scalability, and long-term viability. The report states that industry leaders argue that without increased investment, Replicator will fall short of its goal to field thousands of autonomous systems rapidly.

While Defense News notes that congressional aides expect modifications rather than cancellation, the program’s trajectory hinges on changes in leadership at the US DOD. It mentions that analysts warn that without sustained momentum, Replicator may struggle to deliver the transformative impact envisioned at its launch.

China is taking the threat seriously. Defense One reported in May 2025 that aside from the Shen Nung 3000/5000 anti-drone laser, China Aerospace Science and Industry Corporation (CASIC) has developed the LW-30 and LW-60, which offer vehicle-mounted interception with AI-driven automation.

Additionally, Defense One reports that China has developed a breakthrough cooling system, which enables continuous laser operation by eliminating heat buildup—a longstanding challenge to the effectiveness of laser weapons.

The report states that these advancements underscore China’s commitment to reducing its reliance on costly missile interceptors while enhancing precision and operational efficiency.

By testing its lasers in foreign wars, China is quietly mastering the weapons it may one day unleash in the Taiwan Strait.
