WASHINGTON — The U.S. Navy has taken delivery of the first AN/SPY-6 radar array for the Flight III Arleigh Burke-class destroyer Jack Lucas, which was designed and built specifically to accommodate the upgraded air and missile defense radar.
The Raytheon-built system is about 30 times more sensitive than the SPY-1 arrays on the Navy's cruisers and destroyers, but it requires much more power. That led to a significant redesign of the Flight IIA DDG.
Jack Lucas, being built at Ingalls Shipbuilding in Pascagoula, Mississippi, is the first of the new builds. The ship is scheduled to be delivered in 2024, according to Navy budget documents.
The delivery of the first SPY-6 marks a significant step for the radar, which looks poised to rapidly become the fleet standard. The Navy plans to install a scaled-down version of the radar on the older Arleigh Burke-class destroyers to keep them relevant, as well as on the future frigate, FFG(X), being built by Fincantieri.
Wes Kremer, president of the Raytheon Missiles & Defense business, said in a July 15 interview with Defense News that the radar is designed to simultaneously handle multiple missions without losing fidelity on any individual mission.
“SPY-6 is an evolutionary step forward in radar capability, but it was, most importantly, designed with incredibly long range and sensitivity to support all the missions that Navy destroyers do: ballistic missile defense, surface warfare and anti-air missions simultaneously,” Kremer said. “And what's sometimes lost in the noise is that it can do [its job] in the presence of electronic attack or jamming. That's really the magic of that radar.”
Kremer is confident the radar has been put through its paces in the acquisition process and that the next major hurdle for the program will be Jack Lucas' sea trials.
“These radars are being delivered under the low-rate initial production run,” he said. “For about three years now we've had a test radar in Hawaii and proving out the radar. We've also delivered an array to Navy's [Combat Systems Engineering Development Site] in Moorsetown, New Jersey. This isn't just a radar — it's part of Flight III, which is not just the radar, it's Lockheed Martin's Aegis Baseline 10, and we are fully integrated. So we've already gone through all that, so really the next step is sea trials.”
The Navy wants to start backfitting the scaled-down version of SPY-6 in 2021, Capt. Jason Hall, who is the above-water sensors program manager at Program Executive Office Integrated Warfare Systems, said in January. But beyond that, Kremer said Raytheon is looking to Japan and South Korea as potential customers for SPY-6.
The Navy's investment in SPY-6 is not without some controversy. Bryan Clark, a senior fellow at the Hudson Institute, said while the Navy needs a radar like SPY-6 for ballistic missile defense, the service still must figure out how to perform passive detection to avoid giving away its location to adversaries that will be able to electronically sniff out a big, powerful radar.
Kremer said he wasn't comfortable discussing concepts of operations surrounding the issue of keeping electronically quiet with SPY-6. But he reiterated that during active electronic attack, the radar would perform.
“You have to be able [to] operate around electronic attack, and on the active side we have a lot of capability to do that,” he said. “But when you get into that other stuff, you're really starting to talk about concepts of operations, and I don't think it's appropriate for a contractor to talk about CONOPS.”
The Navy is also planning to scale back construction of the Flight III destroyer. In its most recent budget submission, the Navy cut four of the planned 12 Flight IIIs over the next five years as the service tries to juggle the enormous bill for the Columbia-class ballistic missile submarine.

Israel's northern border with Lebanon and Syria represents a potential flashpoint in the conflict that erupted over the weekend — one that experts say bears watching over the next several days because it could be a harbinger of a wider regional war in the Middle East.

By: Aaron Mehta WASHINGTON — The U.S. Army on Friday issued a draft request for proposals for the preliminary design phase of its delayed optionally manned fighting vehicle, or OMFV, the first major step in a relaunched competition to replace the Bradley Infantry Fighting Vehicle. The preliminary phase will be open for 40 days, with the goal of gathering industry feedback ahead of the final RFP, which will come later this year. That final RFP will award of up to five design contracts in June 2021, setting the next stage in the competition. “As we continue to progress through the first phase of our five-phased approach for the OMFV program, communication, inclusive feedback and innovative thinking from industry remains key,” Maj. Gen. Brian Cummings, the Army's program executive officer for ground combat systems, said in a statement. “We are looking forward to receiving feedback and learning from industry what's in the realm of the possible as we continue to develop this truly transformational vehicle for our Soldiers.” Added Brig. Gen. Ross Coffman, director of the Next Generation Combat Vehicles Cross-Functional Team: “Accurately defining the desired set of capabilities without over-constraining the design is critically important. “The Army is committed to open communication with industry to ensure the characteristics and eventual requirements of the OMFV are informed by technological advances.” The focus on gathering industry feedback should not be a surprise, given the recent history of the program. When the OMFV program was conceived, the Army planned to hold a prototyping competition, selecting two winning teams to build prototypes with a downselect to one at the end of an evaluation period. But in October, the Army ended up with only one bidder in the OMFV competition — General Dynamics Land Systems — after other competitors dropped out, citing requirements and schedule concerns. As a result, the Army in January announced it would be relaunching the program to ensure more competition going forward — a decision that led to service leaders taking heat from Congress during testimony in March. OMFV is the first large acquisition effort to come out of Army Futures Command. The draft RFP, posted on a government contracting website Friday, drives home the point by stating: “To permit industry design freedom and promote innovation, the Army has avoided quantifying or prescribing critical levels of performance wherever possible.” “We do not want to box industry into a solution,” Cummings said. “We want to incentivize industry as they lean forward and think creatively to bring the Army innovative technologies and solutions necessary to achieve our vision — both in terms of the ability to integrate newer technology we are seeing today and leaving space for future growth on the OMFV platform.” https://www.defensenews.com/land/2020/07/17/army-drops-draft-rfp-for-bradley-replacement/

By: Daniel Cebul WASHINGTON — Even as Army leadership points to the great progress made toward interoperability of missile systems, the future could take that vision one step further. During a Monday panel hosted by Defense News at the Association of the United States Army annual meeting, Col. John Rafferty, director of the Long-Range Precision Fires Cross-Functional Team, said the Army aspires to have “an integrated network, rather than interoperability, which is the work around" in the meantime. "When we get into operational strategic fires we want to extend the systems approach across the fires warfighting function, offensive and defense,” Rafferty added. Tom Karako, director of the Center for Strategic and International Studies' Missile Defense Project, stressed that a more aggressive approach to integrating offensive and defense fires is required to defeat current and future near-peer threats. One area Karako has his eye on “is the degree of integration between Maneuver SHORAD, and frankly the whole rest of ARMY AMD, as well as offensive fires. Making sure that interoperability or integration is common as opposed to being another stovepipe of excellence.” The Integrated Air and Missile Battle Command System (IBCS) is one Army program that will be key to achieving integrated fires. The brains behind the Army's future air and missile defense command-and-control system, IBCS will improve the operational capabilities of current AMD systems like THAAD and Patriot by connecting the former disparate systems. When integrated, the Army can leverage THAAD's AN/TYP-2 radar to extend Patriot's effective range and provide a clearer picture of incoming threats. Discussing the importance of integrated air and missile defenses, Karako said, “just as there is that full spectrum of air and missile threats, we're going to need to have a full spectrum and integration of air and missile defense.” Rafferty and his team have not overlooked the significant investment being made in long-range precision fires. “I definitely feel like we are the number one modernization priority for the Army,” Rafferty said. “I also realize that with the investment comes a sense of cost consciousness because we know that hard choices were made ... across the Army to resource this number one priority.” And while Rafferty's cross functional team is receiving significant funding, the Army knows it has to work as a team to achieve its goals. As explained by Brig. Gen. Alfred Abramson, the program executive officer with PEO Ammunition, the Army has to put their heads together to figure out “where's the juice worth the squeeze in terms of investment." "Can we build a better mouse trap so to speak with some limited dollars, because you can't spread it across everything,” said Abramson, adding that his organization has seen a significant spike of about $2.5 billion for fiscal years 2017 to 2022 funding for ammunition and armament systems products. "At the same time we have a conversation with Col Rafferty's organization about what direction should we be heading. So it really is a discussion across these organizations to make sure everybody is focused on the same thing.” https://www.defensenews.com/digital-show-dailies/ausa/2018/10/08/army-looks-to-a-future-of-integrated-fire
