Developed by the Imperial Japanese Navy (IJN) as a short-range, land-based interceptor, the J7W was a response to Boeing B-29 ...
Japan and the United States on Wednesday signed an arrangement to jointly develop a new type of missile defense system as the allies seek to defend against the growing threat of hypersonic weapons ...
The Silbervogel was the first design for a hypersonic weapon and was developed by German scientists in the 1930s, but was never constructed. [6]The ASALM (Advanced Strategic Air-Launched Missile) was a medium-range strategic missile program developed in the late 1970s for the United States Air Force; the missile's development reached the stage of propulsion-system testing, test-flown to Mach 5 ...
The aircraft's port engine caught fire, causing it to crash into a residential area near present-day Eda Station (Kanagawa).

Japanese investigators have determined that a collision during a nighttime drill caused the deadly crash last month of two Japanese navy SH-60K Seahawk helicopters, the country's defense minister ...
Hypersonics, like the Avangard HGV, generally use scramjet engines to achieve hypersonic speeds. Scramjet engines function only when the glide vehicle reaches mach 4.5. These engines are disengaged as the HGV enters the terminal phase of its flight. Failure to deactivate the engines would cause a catastrophic build up of heat in the vehicle as ...
Lack of instructions to the crew and their failure to keep a lookout and communicate led two Japanese navy helicopters to collide during training, killing all eight people on board, a Japanese ...
