Does the Aegis Need to Be Clost to the Lunch Place of a Misslie to Shoot It Again

The signature of a warhead approaching from space lights up the radar screen. A 2d appears, then a third. Soldiers of the 11th Air Defense Arms Brigade are watching, poised at radar, communications, and launch consoles in this dark room. Someday, how these soldiers perform may make the difference between peace and nuclear state of war. But not today. This is simply practice.
The radar blips, the plots of missile trajectories, and the tracks of anti-ballistic missiles screaming toward an intercept on the border of space are computer simulations, made uncannily realistic by the millions of dollars of launch and radar equipment surrounding these control vans in the New United mexican states desert. Razor wire, drawn weapons, and chemical suits add a "This is not a drill" temper to what is, in fact, a drill. They were all function of a mission rehearsal I witnessed in early on 2014 at the McGregor Range, a 600,000-acre preparation expanse thirty minutes from El Paso, Texas, managed past the Ground forces and the U.South. Bureau of Land Management. On either side of the gate to the range stand Nike, Hawk, and Falcon missiles, interceptors made obsolete past the ones the artillery unit was practicing to burn down.
The soldiers of the Alpha-2 anti-missile battery did not know at the time that they were before long to be deployed to Guam, an isle of about 200 square miles in the Pacific Body of water and within reach of North Korea's intermediate-range missiles. In the bound of 2013, Democratic people's republic of korea had threatened to strike U.S. bases in Japan as well as Guam's Andersen Air Strength Base, home of the B-52 bombers that had merely participated in military exercises with Republic of korea. Since that fourth dimension, the Army has deployed anti-missile batteries to Guam in one-twelvemonth rotations, and next year will station a battery there permanently.
The weapon that Alpha-two is trained to use is chosen Terminal High Altitude Expanse Defense force, an anti-ballistic missile arrangement designed to intercept and destroy missiles already headed toward a U.Due south. target or an ally. Nether an Ground forces contract, Lockheed Martin started developing THAAD in the early 1990s, but the first THAAD bombardment wasn't fielded at Fort Bliss, Texas, where the 11th Air Defense Artillery Brigade is based, until 2008. The system's solid-propellant missiles, fired from a mobile launcher, race to the edge of the atmosphere to smash an antagonist's missiles plunging at hypersonic speeds in the final phase of their trajectories toward globe. The commencement two THAAD batteries at Fort Bliss were equipped with a full of vi launchers. Each launcher has viii interceptors.
Not one has yet been fired in combat. But co-ordinate to the U.S. Missile Defence force Bureau, flight tests since 2006 take scored 13 intercepts out of 13 tries. From those tests have come up data for fine-tuning the fake battles, like the one Alpha-2 fought in the New Mexico desert. Over the nine-day exercise, Alpha-2 fought upwardly to three mock battles per day.
"They can first like hell on wheels, with a lot of trajectories coming your way," said First Lieutenant Abraham Acosta, tactical control officer and launcher platoon leader. Or they can be drawn out, as if the enemy fires a couple missiles, then waits…then fires a couple more than. "Like they are reloading," Acosta said.
Alpha-2's fire control teams, each composed of three soldiers, fought in shifts from vans mounted on the backs of heavy trucks and hardened confronting chemical and armed assault.
The trucks supporting the command vans were parked side by side a quarter-mile or then from truck-borne launchers. Communications cables connected 1 to the other, too as to satellite and ground antennas that link to off-site command centers.
In ane control van, Acosta and Sergeant Brent Chapman, the tactical control assistant, sitting side by side to each other, scoured feeds from ground-, bounding main-, and space-based sensors. Alone in a 2d van, Specialist Christopher Steil, the launch command organisation operator, checked the status of launch command and communications equipment and listened for orders from Acosta. Headsets on, microphones curled to their lips, these three members of the burn down command squad read LCD display screens that showed the location of incoming warheads and the status of interceptors and communications links.
Fifty yards away, in a domed tent that served equally army camp headquarters, Helm Pete Lawall and his staff read the same information and heard the same communications the fire control team got. If these were alive-fire situations, Lawall and his team would be talking to commanders throughout the Command and Command, Boxing Management, and Communications construction that integrates the several layers of the U.Due south. Ballistic Missile Defense Network. The gild to fire a THAAD missile comes from Acosta, the tactical control officer, in the next van over. But the society has to be authorized through the control network: officers who would be on the line with Lawall. The burn down control officer, a liaison who works with Navy, Air Force, and Army commanders, is responsible for determining that no friendly aircraft is in the line of sight betwixt the interceptors and their targets. If in that location'due south a advice failure, however, the determination to burn down rests with tactical control.

Boxing Erupts
In the two vans, three blips on radar screens grabbed the attending of the fire command team. If they had been existent, the blips could have been transmitted by orbiting satellites watching for the first signs of an enemy missile launch. Or they might accept come up from body of water-based radar platforms stationed in international waters, platforms as large as offshore oil rigs, with radar domes hundreds of feet in diameter. Or they might have come up from forward-based radar units on Navy ships.
In the New United mexican states desert, however, they came from a estimator program that mimics the signals from those transmitters. Acosta and Chapman began to "rack and stack" the signals, assigning priority to the one representing the missile nearest to impact.
In a live situation, Aegis, the Navy'south sea-based missile defence force system, would probable take the first shot. It'south designed to intercept and destroy a missile mid-course—from well-nigh where information technology leaves the atmosphere to well-nigh where it reenters. THAAD steps up when the missile approaches or reenters the atmosphere. Custodianship and THAAD areas of responsibleness overlap. THAAD ground-based radar would pick upward the target hundreds of miles away. The 3rd leg of the missile defense triad, the PATRIOT Avant-garde Capability-iii system, fires on threats closer to the ground; the system has a much shorter range, about 22 miles. Those threats are usually cruise missiles, but the PATRIOT organization tin can exist called on to take out a "leaker"—a missile that has escaped the commencement two layers of missile defense.
Atop the THAAD 14-pes booster is a impale vehicle, a five-foot bullet with a movable nozzle that makes mid-grade corrections directed by the system's ground-based radar. In the seconds before impact, a shroud over the nose cone splits, revealing an infrared sensor that guides the vehicle to the target. The 2,300-pound interceptors do not use explosives. Proximity explosives don't work considering an explosion disperses energy. To knock downwardly incoming missiles, the energy of the interceptors must be tightly focused.
Traveling at hypersonic speed, THAAD interceptors must strike hypersonic targets high above the globe. The altitude at which the THAAD interceptors would strike a warhead is classified, just it is safety to say that the time it would take the enemy's incoming missile to travel from this intercept point to the ground would be measured in seconds.
Chapman's eyes focused on the flat screen display, skipping from window to window, checking the color-coded updates on the status of systems. He clicked on the most imminent threat, and Acosta commanded Steil, "Engage the target." Steil pushed a button on his console to burn down an interceptor. Computers choose the launcher and tube to fire, then guide the interceptor on its faux flight.
Acosta, Chapman, and Steil repeated the process, ticking through the blips that, ane by ane, disappeared in tiny puffs of white. The engagement done, the three men reset, non knowing when, or if, the adjacent missiles would come.
The simulations are to alive missile attacks what video racing games are to NASCAR. The activity is all on-screen, but it can still cause an adrenaline blitz. Acosta remembered 1 test in particular: "Inside a second, the whole screen populated with multiple missiles—probably ten." He had only seconds to identify the ones that posed the greatest threat. "You accept to process the ones that requite you the least time so you won't have a leaker," he says.
The software saves millions of dollars that would accept to be spent on hardware for live-burn down tests. Simulations are useful for grooming, merely live-fire tests are notwithstanding the most convincing proof that systems work. The latest live test was conducted final Nov in the vicinity of Wake Island in the western Pacific Sea. The Aegis-equipped destroyerJohn Paul Jones joined forces with THAAD battery Alpha-4, deployed to Wake, to exam how well the units piece of work together to defeat multiple, simultaneous threats—in this example, missiles launched by two U.Southward. Air Force C-17s. The starting time C-17 launched a short-range target, a dummy missile with a 300-kilometer (186-mile) range, similar to that of the Scud B or North Korean Hwasong-5. On Wake, subsequently the THAAD X-ring radar detected the target, the unit launched an interceptor, which rammed the short-range missile. At the aforementioned fourth dimension, a second C-17 launched a medium-range target, detected and tracked past the THAAD radar as well as by the shipboard radar. Within seconds, personnel on theJohn Paul Jones launched a BQM-74E air-breathing drone—a prowl missile lookalike. With both targets in the air, the THAAD bombardment and the Aegis team launched confronting them. An Custodianship missile got the drone, but another Custodianship-launched weapon failed to intercept the C-17–launched medium-range missile. The THAAD team hit and destroyed it.
"That could definitely happen in existent life," says 11th Air Defense Artillery Brigade commander Colonel Alan Wiernicki. "Nosotros don't take any pleasure in the Navy missing it, but we take a lot of pride in the fact that [THAAD] engaged it. That's why we exam things."

The Humans Backside the Hardware
When I visited Fort Bliss in 2014 to observe the simulated missile set on, Colonel Cloudless S. Coward was the commander of the Ground forces's 11th ADA Brigade. In his role, the walls were decorated with photos of anti-ballistic missile batteries and their crews. One photo showed the PATRIOT bombardment to which Coward was assigned during the get-go Republic of iraq conflict. With more than 2,900 soldiers, the 11th is the largest air defense brigade in the U.S. Army. Its leader commands thirty batteries stationed around the world, including 5 THAAD batteries.
The Army spends a lot to railroad train the men and women serving in anti-ballistic missiles. "I would equate their training to [that of] a pilot," Coward said. They are as well amidst the Army'south youngest recruits. "Yous want to get utility out of them, so we wait at who has extended amounts of time on their enlistment," said Coward.
Sergeant Brent Chapman, the assistant tactical officer, is one of the "young 'ins,' " as one officer called them, the xx-somethings hand-picked by the Army, many of whom got their beginning in PATRIOT units. Laid off during the Great Recession, 24-twelvemonth-onetime Chapman stepped into a recruiter's station wanting to specialize in what he knew best: tool-and-dice machining. All the Army slots for those positions were filled. "The recruiter told me PATRIOT is almost like tool-and-die machining," he recalled, laughing. "In that location was a $40,000 signing bonus. So I said, 'I can practise that.' "Chapman spent two years on a PATRIOT crew; switched to THAAD, serving with Alpha-4 when it was stationed in Guam; and then returned to Fort Bliss every bit part of Blastoff-ii.
Launch Command Operator Steil reflected the hubris that comes from youth and from exercises that go according to plan. "Nosotros are just practicing to make certain that nosotros are the best of the best—which we are," he said during the nine-solar day rehearsal.
Captain Lawall was a fiddling more philosophical. Lawall, a West Pointer, served on PATRIOT and in the Air Defense Artillery control; at the time of the simulation, he was the officeholder overseeing Alpha-ii's day-to-mean solar day operations. He pointed out that the battery stationed on Guam occupies Footing Zero for a North Korean nuclear strike. "If we are unsuccessful in our job, and then we are going to suffer for it," he said. "That understanding drives people toward investing in proficiency—that if nosotros fail, the consequences are going to be dire."
When they aren't part of the elaborate grooming missions of simulated boxing and live-fire tests, soldiers of the 11th ADA Brigade train at their desktops nigh every day. Air defence force coiffure members are briefed on a threat and the task they're expected to perform. They and so fight a simulated air battle for nigh an hour with evaluators watching. "The nigh critical part is an after-action review," says Colonel Wiernicki. "The evaluators ship them back to right deficiencies."

Practise Makes…
"Just about every type of worst-instance scenario you can imagine," said Steil when I asked what about the simulations the THAAD batteries are subjected to. The scenarios range from mass casualties to communications failures during air battles; brigade-level officers decide which will be simulated and evaluated.
A long, steady siren blasted five seconds, fell silent, then blasted over again—a wheel that repeated for two minutes. A pulsed siren would take meant "Missile on its way." This one signaled an impending chemic, biological, radiological or nuclear (CBRN) attack. Everyone beyond the camp reached for masks.
"Masks brand you 40 percent stupider," said Sergeant Commencement Course Amanda Questel, brigade commanding officer for CBRN and an on-site evaluator of the Alpha-2 simulations. "That's why we train so much on CBRN."
Anybody had the same time to answer: nine seconds for masks, eight minutes for garments (for an impending chemical assault, soldiers don suits). Questel made the rounds, checking on soldiers. "If they're not done in time, they are casualties," she said, her clipboard at the ready.
She scanned the army camp, ducking into tents. Fire Control vans have their ain air filtration systems. "They're protected," she said, moving on. The rest of the military camp, those in tents or exterior, have merely the suits.
Life in the New Mexico desert is full of drills. "Sometimes nosotros feel like robots," Steil said. " 'Drill' is some other give-and-take for 'programming.' "
If the enemy assaults the camp perimeter, soldiers pick upward their M-16s. In Guam, "strength protection" is handled by the Air Strength, which hosts the THAAD battery. But Blastoff-2 practices to protect itself, simply in case.
"We have to remember that we are always soldiers," said Acosta, who has plenty experience at it. He joined the Army correct out of high school, served 6 years, so joined the Texas National Guard equally an MP. After earning a concern caste at a Catholic college, he rejoined the Army every bit a commissioned officer. (Today Acosta is a helm serving with a PATRIOT battery at Fort Elation.)
During the preparation exercise, a few soldiers smoke. More chew. It's easier, and won't cause a fire: The encampment is dotted with fuel tanks, which supply the generators that go along the lights on and the tents warm. Existence cocky-sufficient is part of Alpha-ii'south defensive posture.
One threat added to the syllabus since the 2014 simulation is cyber assail. "Nosotros have signal and communications officers who are well trained on cyber defence," says Wiernicki. "We'll typically throw a few scenarios at them to assess their ability to identify a potential hack."
"Everything we practice relies on network advice," he adds. "The [cyber] force has increased, and our emphasis on this has increased in the last twelvemonth."
I was surprised to witness another simulation played out in the desert—i that is a big enough threat to Army functioning that an occurrence must exist simulated—and evaluated—before Alpha-ii tin deploy overseas. Amy Braley, a coordinator for the Department of Defense, was on site to evaluate the battery's response to a accuse of sexual attack.
In the simulation a accuse is fabricated, an officer notified, the accuser taken to the quietest place that tin exist found—the armory—and questioned about details. Braley, taking notes, approves the exercise. All involved appear relieved to be able to return to blowing things up—and non necessarily incoming missiles.
There was the time a launch specialist woke to the explosion of an MRE (meals ready to eat) heater—it had been blimp in a soda bottle that rolled to the edge of his bunk. MRE bombs are non unsafe, said Steil, only loud. He was the target of one. "It was 2 a.m.," he recalled. "The tent was pitch black. I was furious. Everyone else got a kick out of it."
Humour also relieves job stress. "What makes [the simulations] stressful is the fourth dimension to respond," said Acosta. "You lot might have only a few seconds."
Acosta and his crew won't go the command to fire unless the warhead has evaded other layers in the missile defense force shield. If THAAD fails, all that'south left is PATRIOT, which is all-time at handling ho-hum-moving threats. Being in the warhead's bull's eye doesn't seem to bother Chapman. "I feel good well-nigh what I exercise," he said. "I similar the fact that we accept optics in the heaven."
In the Army, demand for THAAD is growing. "Every single combatant command is enervating a THAAD unit," says Wiernicki, "and we're expecting that every theater volition have a THAAD battery within the next five to x years."
Maybe the best testify of the system's effectiveness is the displeasure the Chinese have expressed about the proposed deployment of THAAD to South Korea. When South Korean president Park Geun-hye visited President Barack Obama last October, the proposal was on the agenda, simply was not mentioned in the statement on the U.S.-Republic of Korea alliance issued after the coming together. Some analysts believe the prospect upsets the Chinese because the deployment will strengthen the U.S. integrated ballistic missile defence force of the Asia-Pacific region. In the meantime, the soldiers of the 11th Air Defense Arms Brigade continue to practice.
