Beijing's uncrewed trimaran submarine features a central hull with two rear outrigger hulls and an estimated submerged displacement of roughly 900 tonnes. The platform is designed to transit submerged, surface, and raise horizontally stored missile tubes vertically before initiating a launch. Analysts believe the craft can hold 16 to 18 missiles, likely accommodating YJ-20 hypersonic anti-ship weapons. Because it lacks onboard broad-spectrum sensors to independently track moving targets, the vessel must rely on external targeting data transmitted by reconnaissance aircraft, satellites, and other naval assets.

China is developing an unconventional underwater missile platform that could add a new dimension to its military threat against US naval forces. A mysterious uncrewed trimaran submarine, currently undergoing trials, is estimated to carry up to 18 missiles, potentially including the YJ-20 hypersonic anti-ship weapon.
Its unusual design combines the ability to travel underwater with the firepower of a missile arsenal ship, raising questions about how Beijing could use such platforms to challenge US aircraft carrier strike groups in the Indo-Pacific.
According to Naval News, the vessel was identified through satellite imagery and is believed to be undergoing trials at Huludao in China.
The submarine features an unconventional three-hull configuration, comprising a central hull and two smaller outrigger hulls positioned towards the rear. The design appears intended to provide stability when the vessel surfaces, particularly when its heavy missile launch tubes are raised into firing position.
Naval News reported that the central hull contains two large weapons compartments, with missile tubes arranged in circular clusters and stored horizontally. The vessel is estimated to have at least eight launch tubes, with…
Tech giants seeking relief from terrestrial expansion bottlenecks face severe financial barriers if they attempt to move infrastructure into orbit. While domestic electricity reserves can currently handle digital capacity demands, administrative red tape continues to delay conventional facility rollouts. Consequently, infrastructure planners must navigate regulatory delays on the ground rather than relying on off-planet alternatives.
Venture capitalists are seeing dealmaking in autonomous transportation eclipse the previous highs of 2016 and 2017. Emerging artificial intelligence architectures are drastically cutting capital requirements, allowing nascent companies to launch regional robotaxi operations with under $1 million. This shift is fueling broader market momentum alongside several multi-billion-dollar financing and consolidation deals across mobility.
Municipal leaders in Menomonie spent nearly 18 months quietly negotiating with Balloonist LLC, a Delaware shell firm representing an undisclosed major tech corporation. While the project promised hundreds of construction and maintenance jobs, concerns escalated over its projected daily consumption of 75,000 gallons of water and strain on regional infrastructure. The covert process utilized strict nondisclosure agreements and an ordinance revision that reclassified digital data processing as simple warehousing.
