Daniel DePetris: Why does the US defense budget continue to grow? America’s approach needs rethinking.
The U.S. defense budget won’t change if Washington insists on maintaining global primacy.

Lockheed Martin’s SPY-7 Radar Is Going to Sea
Posted on February 5, 2021 by Richard R. Burgess, Senior Editor
ARLINGTON, Va. — Lockheed Martin's new SPY-7 radar will be sailing to sea on the ships of three navies as the company highlights the radar's capabilities for application to other navies, including the U.S. Navy.
The SPY-7, which uses gallium nitride modules, initially was developed for the Navy's Air and Missile Defense Radar competition. It was adapted into the Long-Range Discrimination Radar (LRDR) procured by the U.S. Missile Defense Agency (MDA) as a sensor of the Ground-Based Midcourse Defense system. Being installed at Clear Air Force Station in Alaska, the LRDR is designed to discriminate between incoming warheads and decoys.
The core building blocks [of the LRDR] are the same core building blocks in SPY-7,” said Jon P. Rambeau, vice president and general manager, Integrated Systems & Sensors, Lockheed Rotary and Mission Systems, during a Feb. 2 interview with Seapower. “[SPY-7] is a modular radar that allows us to build different configurations for both land-based and sea-based applications.”
The SPY-7 has been selected by the Spanish navy to integrate it with the Aegis Combat System on its F110 frigates. The Canadian navy is procuring the radar to install it on its new Halifax-class surface combatant.
Japan had selected the SPY-7 for its two planned Aegis Ashore ballistic-missile defense sites, but when the plans were cancelled in part out of concern for missile debris falling on populated areas, Japan shifted to a plan to deploy the SPY-7 on some future, unspecified sea-based BMD platform. Japan already has BMD capabilities in its Kongo-class guided-missile destroyers with Aegis systems using the SPY-1 radar.
Japan, which already has placed an order for the SPY-7, “is going through a process now to determine exactly what that platform is going to look like,” Rambeau said. “We are pleased with the progress that the technology has made, and we're starting to see some uptake both here in the U.S. as well as abroad.”
“SPY-7 is part of the Aegis common source library (CSL) and the interfaces are understood,” said Patrick W. McNally, director of communications for Integrated Warfare Systems & Sensors, in a statement to Seapower. “For Japan, we have completed the first of three releases which were recently demonstrated to MDA. Starting from the CSL, with over one million lines of code, Japan will be receiving the best of both Baseline 9 and 10 [Aegis software].”
The U.S. Navy is considering backfitting some Flight IIA Arleigh Burke-class guided-missile destroyers with a radar more modern than the SPY-1, and Lockheed is keeping a watch on developments in the event the SPY-7 could complete in the program if it comes to pass.
Rambeau said his company also “has some more affordable options available to upgrade some of the SPY-1 arrays to provide improved sensitivity and improved resistance to electronic attack and we think we can do that at a fraction of the cost of a wholesale replacement, so we've put forth a couple of options for upgrades to SPY-1 to both MDA and the Navy.”

DoD unveils electromagnetic spectrum superiority strategy
Mark Pomerleau WASHINGTON — The U.S. Department of Defense released its highly anticipated electromagnetic spectrum superiority strategy Thursday, aimed at guiding how the department will develop capabilities as well as partner on and pursue readiness within the spectrum to gain an edge on sophisticated adversaries. In recent years, U.S. adversaries have sought high-tech methods to deny the electromagnetic spectrum, on which American forces often rely. These methods include jamming or spoofing communications, radars and munitions. “The Nation has entered an age of warfighting wherein U.S. dominance in air, land, sea, space, cyberspace, and the electromagnetic spectrum (EMS) is challenged by peer and near peer adversaries,” the strategy stated. “These challenges have exposed the cross-cutting reliance of U.S. Forces on the EMS, and are driving a change in how the DoD approaches activities in the EMS to maintain an all-domain advantage." "This jeopardizes the U.S. military's ability to sense, command, control, communicate, test, train, protect, and project force effectively. Without the capabilities to assert EMS superiority, the nation's economic and national security will be exposed to undue and significant risk.” The strategy lists five strategic goals, each delving deeper into subordinate objectives. They include: Develop superior EMS capabilities. Evolve to an agile and fully integrated EMS infrastructure. Pursue total force readiness in the EMS. Secure enduring partnerships for EMS advantage. Establish effective EMS governance. “The new strategy will have wide-ranging impacts across the DoD. It will shape the future of the department, influencing how the DoD makes decisions on how best to design, resource and implement EMS concepts as a new foundation for multidomain war fighting,” a defense official said Oct. 29 during a briefing to reporters on the strategy on background because the DoD would not let them speak on-the-record. The strategy pulls from previous concepts and initiatives such as the 2013 Electromagnetic Spectrum Strategy and the 2017 electronic warfare strategy. However, since those documents were devised, the operational environment has become more complex. “The primary focus is a holistic approach to electromagnetic spectrum management and electromagnetic warfare,” the official said regarding departures from previous strategies. In the past, the official said, some of those activities were siloed while the new strategy articulates freedom of action within the spectrum through a more holistic approach. The strategy also noted that the DoD is transitioning from its definition that electronic warfare is separate from spectrum management to a more unified approach of electromagnetic spectrum operations, or EMSO. The Joint Staff updated its doctrine document in May governing electronic warfare, shifting to EMSO. The official said some of the particular technologies the department is looking for include dynamic spectrum-sharing technologies that need to incorporate sensing, accessing, sharing and maneuvers, frequency agility, frequency diversity, tools that minimize an EMS footprint, tools to reduce vulnerability detection, and resiliency against radio frequency-enabled cyberattacks. “We're also emphasizing modular, open-systems approaches, software designed systems, [a] more platform-agnostic approach instead of defined platforms as well as being multifunction,” the official said. The strategy paints broad strokes for what's desired and required beneath each strategic goal. However, the Pentagon is still working on a formal implementation plan to ingrain them within the department and armed services. Within 180 days of being officially signed, the senior designated official, who is currently the vice chairman of the Joint Chiefs of Staff, will create a road map and implementation plan alongside the Electromagnetic Spectrum Operations Cross-Functional Team. A defense official said the way forward should be finalized by March 2021. That plan will have a series of tasks aligned to the five goals. What's more, the implementation team will identify risks to the department and outline trade-offs that must be made against other priorities within the Pentagon, the official said. “As part of the implementation plan, we are trying to set the conditions to make the appropriate trades that are going to be necessary with all the different priorities and the modernization efforts that are going to be required as part of this strategy execution,” the official said. https://www.c4isrnet.com/electronic-warfare/2020/10/29/dod-unveils-electromagnetic-spectrum-superiority-strategy/
