KF94 masks are premium face masks made in South Korea and Sonali Advani, MBBS, assistant professor of medicine at Duke University, told NPR that the KF in KF94 stands for Korean filter.

Chinese nuclear-powered Type 094A Jin-class ballistic missile submarine in the South China Sea, April 12, 2018.

It has already been tested three times but so far China is saying nothing. The JL-3, the country s most advanced submarine-launched long-range missile, is projected to be fully integrated with the PLA s next generation of submarines in 2025, but China has not officially confirmed that it is even under development.
