While China's supersonic missile tests have caused deep concern in Washington and its allies, a US general has said Beijing is more advanced in the technology.
Gen. David Thompson, deputy chief of staff for space operations in the U.S. military, acknowledged Sunday morning that US supersonic missile capabilities are not as advanced as those of China or Russia.
In an interview on the sidelines of the Halifax International Security Conference in Canada, Thompson said this shows that the United States has lagged behind in developing the latest and most advanced weapons.
According to the Politico website, quoting the interview, he acknowledged that Washington's backwardness from the other two countries (Russia and China) was potentially dangerous to US national security.
