China says new supersonic sub would reach San Francisco in 100 minutes

World News - Breaking International News Headlines and Leaks

China is developing a’supersonic’ submarine that could travel from Shanghai to San Francisco in less than two hours.

Researchers say their new craft uses a radical new technique to create a ‘bubble’ to surround itself, cutting down drag dramatically.

In theory, the researchers say, a supercavitating vessel could reach the speed of sound underwater, or about 5,800km/h. 

The new sub envelops a submerged vessel inside an air bubble to avoid problems caused by water drag

The technology was developed by a team of scientists at Harbin Institute of Technology’s Complex Flow and Heat Transfer Lab. 

Li Fengchen, professor of fluid machinery and engineering, told the South China Morning Post he was ‘very excited by its potential’.

The new sub is based on Soviet technology developed during the cold war.

Called supercavitation, it envelopes a submerged vessel inside an air bubble to avoid problems caused by water drag.

Traditional submarines suffer from drag underwater, which limits their speed. 

A Soviet supercavitation torpedo called Shakval was able to reach a speed of 370km/h or more – much faster than any…

She worked as a legal assistant while she pursued her master’s in forensic science. After obtaining her MS. degree she continued to work in the legal field for years till she got involved in the pre-planning business. She is working on her PhD in forensic psychology at GCU: Her current PhD focus of analysis is assisting in the process of perfecting our current LIFE EXPECTANCY CALCULATOR to include ELEVATION / LONGITUDE / LATITUDE / POPULATION DENSITY and NUTRITION variables and their relationship to life span and quality of life to produce a dissertation topic that focuses on solutions to the problem. Improving educational skills training can elevate quality of life while raising life expectancy. (Klocko, et al., 2015). A qualitative approach, utilizing both quantitative statistics over time and qualitative population sampling, would best represent all angles of this topic (Stimpson & Walker, 2020).
