In an exclusive interview with ABC News' Martha Raddatz, Adm. Timothy Keating, head of the U.S. Pacific Commands, said that the military is prepared to shoot down any North Korean ballistic missile -- if President Obama should give the order.
"If a missile leaves the launch pad we'll be prepared to respond upon direction of the president," Keating told ABC News. "I'm not a betting man but I'd go like 60/40, 70/30 that it will, they will attempt to launch a satellite. There's equipment moving up there that would indicate the preliminary stages of preparation for a launch. So I'd say it's more than less likely."
"Should it look like it's not a satellite launch -- that it's something other than a satellite launch -- we'll be ready to respond."
Intelligence reports suggest that North Korea is preparing a long-range missile test. Earlier this week, North Korea announced its plans to send a satellite into orbit as part of its space program.
However, many in the international community assert that North Korea's satellite test is simply a means of concealing a long-range missile test -- a move that would flare existing tension in the region.
Keating said that the military is ready to respond with at least five different systems: destroyer, Aegis cruiser, radar, space-based system and ground-based interceptor. All of these work in conjunction with one another to protect against any missile threat.
Destroyers are fast, multi-purpose warships that can be used in almost any type of naval operation. They would likely play a defensive role, helping to repel an air attack and offering a platform for gunfire and missiles to hit airborne objects.
The Aegis cruiser is part of the Navy's computer-based command and control system that integrates radar and missiles to fight against land, air and sea attacks. For Keating, the Aegis combat system can tracks threats and counter any short- or medium-range missiles.
Radars vary in type and design, but the military would likely employ a range of sea-based and early warning radars to detect the presence of a North Korean missile, track warheads' movement and more easily home in on the position of a missile to knock it down.
Space-based infrared system is a defense system that provides warning of any missile launches, detecting the threat and employing other tools to obliterate it.
Ground-based interceptor is a weapon that seeks and destroys incoming ballistic missiles outside of the earth's atmosphere. Its sensors give the military the ability to locate and obliterate a North Korean missile.
"We will be fully prepared to respond as the president directs," Keating said. "Everything that we need to be ready is ready. So that's ready twice in one sentence, but we're not kidding, it doesn't take much for us to be fully postured to respond."
In the U.S. arsenal is a "very sophisticated and complex, but effective ballistic missile-defense system," Keating says, which would provide a line of attack against any kind of ballistic missile or warhead that springs from a North Korean launch pad.
Ground-based interceptors, he says, will be able to take down an object other than a satellite. And while they have not moved ships into place yet, Keating says he is prepared to do so at a moment's notice.
Experts say that North Korea's announcement of its satellite launch is an attempt to put Pyongyang on President Obama's radar.
