[Shenjiang No. 1 participated in the construction of the deepest submarine tunnel] On August 23, China's self-developed subsea tunnel shield machine rolled off the assembly line in Changsha, Hunan. The equipment shield machine has an excavation diameter of 13.42 meters, a total length of 130 meters, and a total weight of 3,800 tons. It will participate in the construction of China's deepest submarine tunnel-the Zhujiangkou Tunnel of the Shenzhen-Jiangmen Railway. The Pearl River Mouth Tunnel is a key control project of the Deep River Railway. "Shenjiang No. 1" crosses the section with a total length of 3590 meters. The entire line is tunneled downhill for a long distance and passes through the Pearl River estuary. The engineering geological conditions are extremely complicated. Editor/Xu Shengpeng

• On April 14, 2026, the Zhongke Aerospace Lijian-1 Y12 rocket successfully launched "One Rocket, Eight Stars" from the Dongfeng Commercial Aerospace Innovation Experimental Zone. This mission adopts the "special vehicle" launch mode, compressing the contract to launch cycle to 6 months, marking the official entry of China's commercial aerospace into the era of "flight based" mass production. Relying on a pulsating production line, the rocket assembly cycle has been reduced to 30 days, and the future annual production will reach 30 missiles. Editor/Cheng Liting
