Navy to Expand Integration of a New Ship-Defense Technology Able to Destroy Attacking Cruise Missiles

Special Technology Feature: The U.S. Navy is upgrading its fleet of Arleigh Burke-class destroyers with an ability to destroy enemy missiles from beyond-the-horizon.

The Navy plans to expand its emerging "over-the-horizon" ship-launched cruise missile defense technology to a wider range of airborne sensor platforms beyond an E2-D Hawkeye and Marine Corps F-35B - to possibly include the Navy's own carrier-launched stealthy F-35C and F/A-18 Super Hornets, service officials said. 

Citing comments from the Navy's Program Executive Office Integrated Warfare Systems manager for future combat systems, a report from The U.S. Naval Institute news  detailed some Navy plans to further modernize a fire-control system known as Naval Integrated Fire Control - Counter Air, or NIFC-CA. (USNI Report here)

The Navy is already building, deploying and testing a fleet of upgraded DDG 51 Arleigh Burke-class destroyers with NIFC-CA - as a way to bring an ability to detect and destroy incoming enemy anti-ship cruise missiles at farther ranges from beyond the horizon.

The technology enables ship-based radar to connect with an airborne sensor platform to detect approaching enemy anti-ship cruise missiles from beyond the horizon and, if needed, launch an SM-6 missile to intercept and destroy the incoming threat, Navy officials said.

 NIFC-CA has previously operated using an E2-D Hawkeye surveillance plane as an aerial sensor node; it has also been successfully tested from a land-based "desert ship" at White Sands Missile Range, N.M. from an F-35 Joint Strike Fighter. Should the Navy's future plans materialize, the system would expand further to include the F/A-18 and F-35C.

NIFC-CA gives Navy ships the ability to extend the range of an interceptor missile and extend the reach sensors by netting different sensors of different platforms -- both sea-based and air-based together into one fire control system, Navy officials told Scout Warrior in a previous interview.

NIFC-CA was previously deployed on a Navy cruiser serving as part of the Theodore Roosevelt Carrier Strike Group in the Arabian Gulf.

Operating NIFC-CA from an F-35B improves the sensor technology, reach, processing speed and air maneuverability of the system; the test also assessed the ability of the system to identify and destroy air-to-air and air-to-surface targets. A report from earlier this year from the U.S. Naval Institute news quoted Lockheed officials saying an "at-sea" assessment of this NIFCA-CA/F-35 pairing is planned for 2018. 

NIFC-CA has previously operated using an E2-D Hawkeye surveillance plane as an aerial sensor node; the use of an F-35B improves the sensor technology, reach, processing speed and air maneuverability of the system; the test also assessed the ability of the system to identify and destroy air-to-air and air-to-surface targets. A multi-target ability requires some adjustments to fire-control technology, sensors and dual-missile firings; the SM-6 is somewhat unique in its ability to fire multiple weapons in rapid succession. An SM-6 is engineered with an "active seeker," meaning it can send an electromagnetic targeting "ping" forward from the missile itself - decreasing reliance on a ship-based illuminator and improving the ability to fire multiple interceptor missiles simultaneously. 

Unlike an SM-3 which can be used for "terminal phase" ballistic missile defense at much farther ranges, the SM-6 can launch nearer-in offensive and defensive attacks against closer threats such as approaching enemy anti-ship cruise missiles. With an aerial sensor networked into the radar and fire control technology such as an E2-D Hawkeye surveillance plane, the system can track approaching enemy cruise missile attacks much farther away. This provide a unique, surface-warfare closer-in defensive and offensive weapons technology to complement longer range ship-based ballistic missile defense technologies. 

Once operational, this expanded intercept ability will better defend surface ships operating in the proximity or range of enemy missiles by giving integrating an ability to destroy multiple-approaching attacks at one time. 

NIFC-CA is part of an overall integrated air and missile defense high-tech upgrade now being installed and tested on existing and new DDG 51 ships called Aegis Baseline 9.

The system hinges upon an upgraded ship-based radar and computer system referred to as Aegis Radar –- designed to provide defense against long-range incoming ballistic missiles from space as well as nearer-in threats such as anti-ship cruise missiles, he explained.

Developers said integrated air and missile defense provides an ability to defend against ballistic missiles in space while at the same time countering air threats to naval and joint forces close to the sea. 

The NIFC-CA technology can, in concept, be used for both defensive and offensive operations, Navy officials have said. Having this capability could impact discussion about a Pentagon term referred to as Anti-Acces/Area-Denial, wherein potential adversaries could use long-range weapons to threaten the U.S. military and prevent its ships from operating in certain areas -- such as closer to the coastline.

Having NIFC-CA could enable surface ships, for example, to operate more successfully closer to the shore of potential enemy coastines without being deterred by the threat of long-range missiles.

Defensive applications of NIFC-CA would involve detecting and knocking down an approaching enemy anti-ship missile, whereas offensive uses might include efforts to detect and strike high-value targets from farther distances than previous technologies could.  The possibility for offensive use parallels with the Navy’s emerging “distributed lethality” strategy, wherein surface ships are increasingly being outfitted with new or upgraded weapons.  

The new strategy hinges upon the realization that the U.S. Navy no longer enjoys the unchallenged maritime dominance it had during the post-Cold War years.

During the years following the collapse of the former Soviet Union, the U.S. Navy shifted its focus from possibly waging blue-water combat against a near-peer rival to focusing on things such as counter-terrorism, anti-piracy and Visit, Board Search and Seizure, or VBSS, techniques.

More recently, the Navy is again shifting its focus toward near-peer adversaries and seeking to arm its fleet of destroyers, cruisers and Littoral Combat Ships with upgraded or new weapons designed to increase its offensive fire power.

The current upgrades to the Arleigh Burke-class of destroyers can be seen as a part of this broader strategic equation.

The first new DDG 51 to receive Baseline 9 technology was the USS John Finn or DDG 113. The ship previously went through what’s called “light off” combat testing in preparation for operational use and deployment.

The very first Arleigh Burke-class destroyer, the USS Arleigh Burke or DDG 51, is now being retrofitted with these technological upgrades as well.

NIFC-CA technology is also being back-fitted onto earlier ships that were built with the core Aegis capability. This involves an extensive upgrade to combat systems with new equipment being delivered. This involves the integration of new cabling, computers, consoles and data distribution systems. 

As of several years ago, there are seven Flight IIA DDG 51 Arleigh Burke-class destroyers currently under construction. DDG 113, DDG 114, DDG 117 and DDG 119 are underway at a Huntington Ingalls Industries shipbuilding facility in Pascagoula, Mississippi; DDG 115, DDG 116 and DDG 118 are being built at a Bath Iron Works shipyard in Bath, Maine.

Existing destroyers and all follow-on destroyers will receive the Aegis Baseline 9 upgrade, which includes NIFC-CA and other enabling technologies.  For example, Baseline 9 contains an upgraded computer system with common software components and processors, service officials said.

In addition, some future Arleigh Burke-class destroyers such as DDG 116 and follow-on ships will receive new electronic warfare technologies and a data multiplexing system which, among other things, controls a ship’s engines and air compressors, developers said. 

The Navy’s current plan is to build 11 Flight IIA destroyers and then shift toward building new, Flight III Arleigh Burke-class destroyers with a new, massively more powerful radar system. 

The new radar, called the SPY-6, is said by Navy officials to be 35-times more powerful than existing ship-based radar.

Flight III Arleigh Burke destroyers are slated to be operational by 2023.
