The New Missile Gap Is Here (As in the U.S. Military Needs More Missile Defenses)

Pentagon weapons developers and military war commanders are expressing concern that deployed forces simply do not have enough Air and Missile defense assets to meet a fast-changing threat environment involving high volumes of dangerous new enemy weapons.

Pentagon weapons developers and military war commanders are expressing concern that deployed forces simply do not have enough Air and Missile defense assets to meet a fast-changing threat environment involving high volumes of dangerous new enemy weapons.

“The requirements exceed the capacity we have today. When it comes to combatant commander needs for missile defense, we find out we simply do not have enough,” Brig. Gen. Clement Coward, Commander, 32nd Army Air and Missile Defense Command, told an audience at a recent Center for Strategic and International Studies event.

These threats, posed increasingly by major power competitors, include newly emerging weapons such as guided enemy cruise missiles, attack drones, ballistic missiles with maneuvering re-entry vehicles and even “boost-glide” hypersonic weapons.

“We don’t like to say we don’t have air superiority anymore, but there may be forces in locations where we do not have air superiority. We are working on an all inclusive culture change,” Coward said.

The air and missile defense push supports rapid development of more counter-drone weapons and Short-Range-Air-Defense (SHORAD) technologies - some of which are already being engineered into Army Stryker vehicles. A key goal is to design systems, at their inception, with technologies equipped to meet drone and short-range air defense threats.

“We have to bake in requirements for counter UAS (Drones) as part of this. We cannot allow that to be a segmented problem. We are trying to get Short Range Air Defense back in the units,” said Brig. Gen. Sean Gainey, Joint Integrated Air and Missile Defense Organization Director and Deputy Director, Force Protection.

A National Defense University study, called “Joint Integrated Air and Missile Defense, Simplifying an Increasingly Complex Problem,” details further specifics regarding new threat concerns, including the aforementioned weapons such as hypersonic threats and missiles with multiple “re-entry vehicles.”

“These threats demand a multi-layered defense to eliminate exploitable gaps between traditional IAMD (Integrated Air and Missile Defense) categories,” the paper writes.

Other concerns cited in the essay include “lethal, one-way UAS (drones as attack weapons) and long-range, large-caliber rockets equipped with terminal guidance.”

In response, both Coward and Gainey mentioned ongoing collaborative work to revamp weapons networking and integrated fire control technology.

“We are prioritizing upgrades to planned integrative fire control. We are doing a revision of joint integrated fire control across the joint force,” Gainey said.

As a way to further advance this goal, Coward and Gainey cited the example of better networking fire control systems for the PATRIOT Advanced Capability-3 and Terminal High-Altitude Area Defense interceptor missiles. While both of these systems are air and missile defense weapons, THAAD is a longer range system. Connecting radar, targeting and sensor information between these systems brings the US military services closer to the stated objective of having a multi-layered approach.

Integrated Battle Command System

This scenario, involving a specific effort to connect sensors, fire control and targeting information between “nodes” on a dispersed combat area, is what the Army’s Integrated Battle Command System is engineered to do.

IBCS uses a netted-group of integrated sensors and networking technologies to connect radar systems -- such as the Sentinel -- with fire-control for large interceptors such as PATRIOT and THAAD.

Synergy between nodes, using radio, LINK 16 data networks and GPS can greatly expedite multi-service coordination by passing along fast-developing threat information. IBCS, an Army program of record, uses computer-generated digital mapping to present an integrated combat picture showing threat trajectories, sensors, weapons and intercepts, senior Northrop developers told Warrior in previous interviews.

Coward cited IBCS as an example of how emerging technology is moving the military services closer to its intended objectives.

“Gives us flexibility instead of waiting on a shelter attached to a vehicle. It allows us to bring three Combatant Command needs statements together, as opposed to being stovepiped,” Coward said.

In an interview with Warrior Maven, IBCS weapons developers with Northrop Grumman says that now, a Patriot missile does not have to be fired with a PATRIOT radar.

“By integrating sensors together, we can have an environment where any weapon can be used with a common sensor picture. It used to be that you could only fire a PATRIOT with a PATRIOT radar...now you do not have to have that,” Rob Jassey, Air and Missile Defense Program Manager, Northrop Grumman, told Warrior Maven.

Jassey added that, in a prior exercise, Northrop was able to use Sentinel radar maneuver sensors to provide guidance source data for a PATRIOT missile, enabling it to destroy a cruise missile target on the other side of a mountain.

“Because the low altitude trajectory of the target obscured it from the PATRIOT radar field of view, the IBCS used Sentinel composite tracking data to calculate and present the necessary engagement solution,” a Northrop statement said.

F-35 and Ballistic Missile Defense

Northrop Grumman and the Pentagon’s Missile Defense Agency recently analyzed information from a previous demonstration wherein an airborne F-35 helped perform Ballistic Missile Defense missions.

The demonstration used a ground-based F-35 sensor called the Distributed Aperture System, a 360-degree camera-sensor offering F-35 pilots a real-time view surrounding the aircraft. Using a DAS-configured gateway aerial node to locate a ballistic missile launch and flight path, the technical system was able to send target-tracking information using advanced data links from the air to ground-based command and control location.

Described as multi-function array technology, the DAS system uses automated computer algorithms to organize and integrate target-relevant data from missile warning systems, radar, night vision and other long-range sensors; the array is able to track a BMD target from the air at distances up to 800 nautical miles. Such a technology, quite naturally, enables a wider sensor field with which to identify and track attacking missiles.

An airborne DAS, networked with ground-based Patriot and THAAD weapons, could offer a distinct tactical advantage when it comes to quickly locating incoming missile threats. Air sensors in particular, could be of great value given that, in some envisioned threat scenarios, it is unclear whether there would be enough interceptors to counter a massive enemy ballistic missile barrage into US or allied territories.

Regarding Coward and Gainey’s cited concerns, air based detection and target tracking, it seems, could go a long way toward better fortifying defenses - as they might increase the time envelope during which command and control could cue interceptors to locate and destroy attacking enemy missiles.

Counter Rocket Artillery and Mortar

Northrop developers are also assessing new optical sensors, passive sensors and lasers to widen the target envelope for the Army’s Counter Rocket, Artillery Mortar system such that it can destroy enemy drones, helicopters, fixed-wing aircraft and cruise missiles.

C-RAM uses sensors, radar and fire-control technology alongside a vehicle or ground-mounted 20mm Phalanx Close-in-Weapons-System able to fire 4,500 rounds per minute. The idea is to blanket an area with large numbers of small projectiles to intercept and destroy incoming artillery, rocket or mortar fire. As an area weapon, the Phalanx then fires thousands of projectiles in rapid succession to knock the threat out of the sky. Engineers are also looking at new interceptor missiles to compliment the Phalanx, Northrop developers said.

Adding new sensors and weapons to CRAM could bring nearer term improvements by upgrading an existing system currently deployed, therefore circumventing multi-year developmental efforts necessary for many acquisition programs.
