[China’s first wind tunnel for low-altitude aircraft aerodynamic research completed, operational in South China - Global Times](https://www.globaltimes.cn/page/202507/1338569.shtml)

First time I have heard drones which fly low to evade radar being described as “low-altitude aircraft”.

_… This wind tunnel integrates both the traditional aviation wind tunnel and the windshaper for drone testing, making it the first 4.5-meter-class wind tunnel in China dedicated to aerodynamic testing of low-altitude aircraft. It will provide low-altitude aircraft developers with efficient and convenient “on-the-doorstep” testing services, reducing the time from coordination to the completion of experiment to just three to four months. This is expected to significantly cut R&D costs and accelerate the commercialization of technological breakthroughs. …_

Or how about this one?  
[UAE’s Autocraft places 1-bln-USD eVTOL intent order with China’s TCab Tech - Global Times](https://www.globaltimes.cn/page/202507/1338516.shtml)

_Autocraft from the United Arab Emirates (UAE) signed a memorandum of understanding (MoU) with the Chinese electric vertical takeoff and landing (eVTOL) maker Shanghai TCab Technology Co., Ltd. here on Wednesday on purchasing 350 E20 eVTOL aircraft worth 1 billion U.S. dollars. …_

_TCab Tech founder and CEO Yon Wui NG, also former chief engineer of Airbus China, outlined a phased deployment plan for the 350 E20 eVTOL aircraft: The initial use in Abu Dhabi, followed by connections to surrounding cities, and ultimately expansion across the wider region. He emphasized the company’s cost advantage, attributing it to China’s mature aviation and battery-electric propulsion supply chains. …_

Can anyone still seriously argue that the West is NOT lagging far behind in the technology race?

Or this one?

[Submarine delays sinking US edge in a Taiwan war - Asia Times](https://asiatimes.com/2025/07/submarine-delays-sinking-us-edge-in-a-taiwan-war/)

_A widening gap between US submarine ambitions and industrial capacity is reshaping the undersea balance just as China accelerates its challenge beneath the waves. …_

_Ultimately, the US’s edge beneath the waves is eroding not from enemy fire, but from self-inflicted industrial stagnation and delay. Unless urgently addressed, these setbacks could hand China a dangerous opportunity in the Indo-Pacific and a potential Taiwan war win._

I guess we could call this “friendly fire- extinguisher “.

Windshaper, huh?  
Wright’s would be pumped to see one of these in action!
