China has developed a stealth missile speedboat and deployed it in the East China Sea. The news comes after China’s next-generation stealth fighter jet J-20 saw its first test flight last week. Dubbed the “sword without shadow,” the speedboat developed with homegrown technology has successfully passed a dozen tests since 2008. The Stealth Missile Speedboat is apparently deployed in the East China Sea or the South China Sea, where Beijing has sovereignty disputes with neighboring countries.
