Summary and Key Points: China has launched its first nuclear-powered guided missile submarine, the Type 093B, marking a significant enhancement in the country’s naval capabilities. The Pentagon confirmed the development in an October 2023 report, noting that the Type 093B could enable China to conduct long-range precision strikes against land and sea targets.
-The submarine, which displaces over 6,000 pounds and can reach speeds of 30 knots, is equipped with advanced sonar systems and can launch various torpedoes and cruise missiles.
Most Important Point: This development is part of China's ongoing naval expansion, which has raised concerns within the U.S. military about the potential threat to U.S. aircraft carriers and broader regional stability.
China’s navy recently launched its first nuclear-powered guided missile submarine. The Pentagon reported the development in a 2023 assessment of China’s military meant to provide U.S. forces with land and sea attack options in the event of a future conflict.
The Pentagon report, published last October, confirmed that a Type 093B submarine was launched. The vessel relies on a nuclear reactor for power. According to the Pentagon, the Chinese navy will soon “have the ability to conduct long-range precision strikes against land targets from its submarine and surface combatants using land-attack cruise missiles, notably enhancing (China’s) power projection capability,” Reuters reported.
The Type 093B is an SSGN, a conventionally armed missile submarine. The Soviet Union first developed this type during the Cold War to target U.S. aircraft carriers. The U.S. Navy responded with its own version when it converted ballistic missile submarines to carry large payloads of land-attack Tomahawk cruise missiles. These missiles are precision weapons with a long range. They typically operate at low altitudes, sometimes skimming the surface of the sea – in contrast with ballistic weapons, which fly at high altitudes.
The Type 093B measures 351 feet long, with a 36-foot beam and a 24-foot draft. The vessel displaces over 6,000 pounds when submerged and can reach speeds of 30 knots. With a pressurized water reactor, the Type 093B can operate indefinitely and with unlimited range, significantly enhancing China’s scope of naval influence.
The Type 093B sails with 100 crew members. They operate a variety of sophisticated equipment, including Type 359 radar, hull-mounted sonar, flank array sonar, passive intercept array sonar, and towed array sonar. For armament, the Type 093B is equipped with six 533-meter torpedo tubes capable of launching a variety of ordnance, including the Yu-3, Yu-4, and Yu-6 torpedoes, or the YJ-82 anti-ship cruise missile.
“Some analysts say the PLA navy will be eager to deploy the vessels as an extra weapon against aircraft carriers as well as a land-attack platform, allowing strikes from a far greater range than its fleets of smaller attack submarines,” Reuters reported.
The Pentagon report indicated that as many as three of the new Type 093Bs could be at sea within the next year – suggesting that China’s historic naval expansion continues. China’s submarine fleet has swelled to 65 vessels, and it looks set to continue growing.
Understandably, the U.S. is concerned with Chinese submarine expansion, fearing that submarines could be used to target U.S. carriers.
“The effort to track China’s submarines at sea is one of the core drivers of increased deployments and contingency planning by the U.S. Navy and other militaries across the Indo-Pacific region,” Reuters reported.
