The U.S. military is considering the possibility of building a “foam cannon” to fire foam from a cannon in the air as part of an effort to counter the threat posed by North Korea.
But the idea has never been tested and there are concerns that the military might not be ready to deploy a foam cannon in time for the 2020 Olympics, a senior U.N. official told CNN.
“We have no idea what they are going to build,” the official said.
“It is an exercise, but we do not have any firm information on whether it is ready or not.”
The official said the U.s. would seek advice from experts in the field of foam weaponry.
“If they have the capability, we would like to see what the consequences are going into deploying a foam weapon in 2020,” the senior official said, speaking on condition of anonymity because he was not authorized to speak to the media.
A number of U.K.-based military experts said they believe North Korea would be able to use a “bouncing bomb” or rocket to launch a projectile over a large area of land or sea, with an area as large as 20,000 square kilometers.
“A lot of the work that they’ve been doing with rockets in the past has been in the area of a large enough target to get that ball of foam out and bounce it at the target,” one of the experts told CNN, using a term for a ballistic missile.
“I think the ballistic missile, if it did go in, would probably have a range of 100 kilometers or more.”
Another expert said the idea of firing a projectile from a rocket might seem like a great idea.
“The first thing to say is that it is an old idea, which I find odd, given that the North Koreans are not capable of building any kind of rockets,” said the expert, who spoke on condition that his name not be used.
“There are some missiles that can be fired from an airplane.
They don’t have the capabilities to do that.”
The United States has a number of missile defense sites in the Pacific that would intercept incoming ballistic missiles if they landed on U.D.O. bases in Japan or South Korea.
In recent months, there has been a spike in the number of missiles flying toward the U
