patreon.com/jhst3103/posts/hโ€ฆ Hypersonic glide vehicle (HGV) is boosted to altitude before reentering the atmosphere and gliding below 100 km using compression lift. In South Korea, the Agency for Defense Development (ADD) conducted the country's first HGV test launch on October 8, successfully completing maneuvering glide flight with changes in both the vertical and horizontal flight paths. The test area shown on the navigational warning display on launch day extended approximately 500 km. Based on that distance, the test vehicle may have performed 1 vertical maneuver and 1 horizontal maneuver after launch.

patreon.com/jhst3103/posts/dโ€ฆ Although the KSS-III Batch I/II submarines adopted a horizontal launch system using an air turbine pump (ATP) developed by the British company Babcock, research is underway to localize this technology. The Agency for Defense Development (ADD) and Hanwha Ocean completed the development of a water-ram horizontal launch system for application to future submarines through the project titled "Development of a Forced-Ejection Horizontal Launch System for Submarines (21.11โ€“'26.10)" and have completed the development of a water-ram horizontal launch system for application in next-generation submarines. Meanwhile, it is reported that MA-Tech developed core technologies for the ATP-based horizontal launch system and verified the performance of its components and assemblies through the project "Design Technology for Turbo Pumps Using High-Pressure Compressed Air ('23.02โ€“'26.02)".

patreon.com/jhst3103/posts/kโ€ฆ ATACMS missiles held by the ROK Army comprise Block I missiles introduced in 1996 and Block IA missiles introduced in 2002. With 20-30 years having passed since their introduction, aging launch platforms and missiles exceeding their storage lives are restricting operations, while life extension through depot-level overhaul remains limited. This is because the U.S. does not support storage-life extension for ATACMS missiles equipped with cluster warheads due to the Convention on CCW/CCM. These issues have prompted a requirement for a new tactical ballistic missile to replace aging ATACMS stocks, and work on the acquisition program is underway.

patreon.com/jhst3103/posts/2โ€ฆ At the 2026 Sacheon Airshow, Hanwha Aerospace unveiled a small canister-launched, electrically powered counter-drone UAV for the first time. It features a main wing that rotates into position above the center of the fuselage and folding X-shaped tail surfaces. Although canister-launched aircraft commonly use folding wings, this rotating deployment mechanism minimizes the loss of internal space and reduces airframe weight while preserving fuselage integrity and structural stiffness.

patreon.com/jhst3103/posts/aโ€ฆ As FPV drones have emerged as a major threat to tanks and armored vehicles, APS on armored platforms increasingly need countermeasures capable of sustained engagement. Conventional hard-kill APS carry a limited number of interceptor munitions, making it difficult to provide sustained protection against drones repeatedly approaching from multiple directions. Increasing the ammunition load adds weight to the launcher, placing a greater load on its drive mechanisms and potentially limiting high-elevation engagement capability. Adding a reload capability also requires additional installation space. In response, Hanwha Systems is developing Directional Counter-Measures for APS (DCMA) for tanks and armored vehicles with support from the "Intelligent Active Protection Technology Against Multiple Threats for Next-Generation Infantry Fighting Vehicles ('23.03~'26.10)" program.
