New Large Chinese Submarine With Very Unique Feature Just Caught On Satellite Imagery
A large submarine apparently designed without a traditional sail has emerged at Jiangnan Shipyard in Shanghai, captured in June 1 satellite imagery from Vantor and reported by Naval News and The War Zone. Sail-less designs trade away the raised structure that carries periscopes, sensor masts, antennas, and snorkels in exchange for streamlining, reduced drag, lower acoustic signature, and higher submerged speeds. The hull also features an X-form rudder configuration and what may be a shrouded pumpjet propulsor, both consistent with quieter, faster operation.
Naval News analyst H.I. Sutton estimates the boat at roughly 120 m (394 ft) long and 10 to 11 m (33 to 36 ft) wide, larger than China's Type 093 nuclear attack submarines and longer than the US Navy's Virginia class. Its designation and intended role are not known, though the lineage is traceable: JN Shipyard launched a smaller (~45 m) sailless demonstrator in 2018, and parent firm CSSC displayed a giant uncrewed underwater vehicle of similar hullform at Zhuhai in 2024. The US Navy has worked in adjacent territory, with a Large Scale Vehicle Range subscale demonstrator in Idaho and a 2021 contracting notice for inflatable sail concepts, but those efforts have remained experimental.

Boeing Validates MQ-28’s Radar Cross Section \\ The Aviationist
Boeing has announced the completion of radar cross-section testing on its MQ-28 Ghost Bat collaborative combat aircraft, with the airframe placed in an anechoic chamber to measure the radar return produced by design features including side intakes, cranked-kite wings, and canted V-tails. The company has not disclosed actual RCS values. The test arrives in an active program cadence: the MQ-28 completed its first three flights over the Point Mugu Sea Range in May for its US debut, the AIM-120 AMRAAM was live-fired from the platform in December 2025, and an E-7 Wedgetail has controlled two MQ-28s in tests against simulated airborne targets. The program now spans 55 Australian companies with reported funding above $600 million.
Germany’s new unmanned helicopter just flew for the first time \\ Defence Blog
German firm AVILUS flew the first prototype of its Wespe 9Y-01 unmanned helicopter. The platform is built around an operational gap the company says is becoming difficult to fill with crewed aircraft: casualty evacuation across contested airspace, where air defense and drone threats make low-altitude medevac approaches increasingly costly. The Wespe carries a stated 200 to 350 kg (440 to 770 lb) payload across 300 km (186 mi) at a 120 km/h (75 mph) cruise, with modular mission bays for a medical cabin, cargo drops, or targeting systems. AVILUS says the airframe packs into a 20-foot ISO container and can navigate without GPS via onboard autonomy.
