The Soviet relic that became China's primary nuclear and conventional bomber

In short: Born from a 1950s Soviet license, the Xi'an H-6 has evolved from a simple twin-engine jet into a sophisticated platform. Today, it remains the only Chinese military aircraft assigned nuclear weapons, serving as a critical tool for power projection across the South China Sea and Taiwan Strait.

Originally produced under licence from the Soviet Tupolev Tu-16, the twin-engine heavy bomber known as the Xi'an H-6... Following a 1957 agreement, China received production kits and raw materials from Plant No. 22 in Kazan to jumpstart domestic manufacturing. While early production was complicated by the chaos of the Cultural Revolution, the aircraft has undergone extensive, decades-long modernization to remain relevant in modern warfare.

Modern variants have transformed the airframe's capabilities. The H-6K, which first flew in January 2007, features a reinforced structure, composite materials, and a glass cockpit. It can carry a variety of munitions, including YJ-12 supersonic cruise missiles and YJ-21 hypersonic ballistic anti-ship missiles. More recently, the H-6M variant has been used as a mother ship to launch the WZ-8 hypersonic unmanned reconnaissance vehicle.

Perhaps most significantly, the H-6N variant—nicknamed 'Thunder God'—serves as China's current nuclear delivery platform. As of 2025, the 106th Air Brigade at Neixiang County operates 20 of these bombers, carrying up to 20 JL-1 air-launched ballistic missiles. While the H-6N holds this vital strategic role, the Xi'an H-20 is expected to eventually assume these nuclear duties.

The aircraft's presence is a frequent flashpoint in regional geopolitics. Since 2019, H-6K and H-6N bombers have conducted joint patrols with Russian Tu-95MS strategic bombers, leading to interceptions by US, Japanese, and South Korean fighter aircraft. These movements are central to China's power projection regarding the political status of Taiwan and disputes in the South China Sea.
