    Four Nations To Be Protected With Lockheed Martins Next Generation Radar

    Moorestown, N.J., January 14, 2020 – Through partnerships with the U.S. Government, Spain, Japan, and Canada, Lockheed Martin's (NYSE: LMT) solid state radar (SSR) technology will provide front-line defense to nations around the world with cutting-edge air and missile defense capabilities. These nations are part of a growing SSR family of 24 platforms, ushering in the next generation of maritime and ground-based advanced radar technology. The basis of SSR is the Long Range Discrimination Radar (LRDR), which the Missile Defense Agency (MDA) selected Lockheed Martin to develop in 2015 with an on-track delivery set for 2020. In 2019 Lockheed Martin's SSR for Aegis Ashore Japan was designated by the United States Government as AN/SPY-7(V)1. What is SSR Technology? SPY-7's core technology is derived from the LRDR program, which has been declared Technical Readiness Level 7 by the U.S. Government. The technology consists of a scalable and modular gallium nitride (GaN) based “subarray” radar building block, providing advanced performance and increased efficiency and reliability to pace ever-evolving threats. As part of its investment into the advancement of SSR, Lockheed Martin built a Solid State Radar Integration Site to conduct detailed testing to prove the maturity of the system and reduce fielding risk. Scaled versions of the LRDR site will be utilized for future radar programs including Aegis Ashore Japan, Canadian Surface Combatant and MDA's Homeland Defense Radar in Hawaii. Solid state offers powerful capabilities to detect, track and engage sophisticated air and missile threats, including the very complicated task of discriminating – or picking out – and countering lethal objects present in enemy ballistic missiles. The Lockheed Martin SSR uses state-of-the art hardware and an innovative software-defined radar architecture to meet current requirements while providing extensibility features to pace evolving threats for decades to come. Its unique maintain-while-operate capability provides very high operational availability and enables continuous 24-hour/7-day week operation. Solid state radar is a multi-mission system providing a wide range of capabilities, from passive situational awareness to integrated air and missile defense solutions. The combined capability and mission flexibility of Lockheed Martin's SSR has gained the attention of new and current users of the Aegis Weapon System, the world's premier air and missile defense combat suite. Meeting the World's Most Demanding Missions While LRDR is the first program to utilize Lockheed Martin's new SSR building blocks, over the past three years Lockheed Martin has consistently been selected in open competitions to equip an additional 24 platforms in four nations. SPY-7 provides several times the performance of traditional SPY-1 radars and the ability to engage multiple targets simultaneously with the latest proven interceptors. Spain's Ministry of Defense stated its preference for Lockheed Martin's technology for its five F-110 class frigates in 2017 and awarded the ship construction order to Navantia in 2019. These ships will host the first-ever S-band variants of the SPY-7 radar for the Spanish Navy. Production will be a collaboration between Lockheed Martin and Spanish company, Indra. When the frigates deploy in 2026 our SPY-7 variant will be integrated as part of the Aegis Weapon System. The frigates will also incorporate the International Aegis Fire Control Loop (IAFCL) integrated with SCOMBA, the national combat system developed by Navantia. Canada's Department of National Defence also selected Lockheed Martin as the naval radar provider for its 15 Canadian Surface Combatant (CSC) ships. Lockheed Martin's IAFCL is integrated with Canada's combat management system, CMS 330, developed by Lockheed Martin Canada for the Royal Canadian Navy's HALIFAX Class ships. The program will make Canada the owner of the world's second largest Aegis fleet, and our SPY-7 radar variant will enable CSC to conduct highly advanced maritime missions for decades to come. Mature, Cost-Effective Systems Ready Now Including LRDR, the 24 Lockheed Martin SSR platforms selected to date represent a total of 91 antennas of varying sizes, collectively composed of over 15,000 subarrays. On LRDR alone, Lockheed Martin has produced an equivalent of eight Aegis shipsets to-date. The U.S. Government's LRDR has a planned service life for decades to come and will be supported and maintained throughout that period. This ensures the U.S. and its allies will have a large and stable base of cost-effective logistics and support for many years in the future.

  • For the Navy’s hospital ships, networking is yet another challenge

    For the Navy’s hospital ships, networking is yet another challenge

    Andrew Eversden When the Navy hospital ship Comfort deployed to Haiti in 2010 following devastating earthquakes, media organizations broadcasting in the area ate up so much satellite bandwidth that the ship had to revert to paper processes and adjust its satellite communications for some ship-to-shore messaging. While the outages weren't a widespread issue, said Sean Kelley, who served as the ship's top IT officer at the time, the problem highlighted a challenge these ships face: broadband. Now, the hospital ships Mercy and Comfort are deployed to Los Angeles and New York, respectively, and are in the national spotlight as symbols of the coronavirus pandemic relief effort. But security and IT experts say the ships' mission presents the Navy with distinct networking problems, from cybersecurity to network connection for patients. Onboard devices When disaster strikes, the Navy's hospital ships deploy in a matter of days, mobilizing with a crew of about 100-1,200 personnel. But the influx of staff also leads to an incursion of devices, all of which must be secure and require bandwidth. “You have a lot of different people going to a lot of different places that now have to be acclimated to this environment,” said Kelley, now executive vice president at Unissant, an IT and cybersecurity company. “So that's really one of the biggest challenges, is getting all those things turned on, all those things activated, making sure that they are all compliant with the latest patches and fixes, and making sure they're good.” This process can be a “nightmare,” said retired Rear Adm. Danelle Barrett, former deputy chief information officer of the Navy and cybersecurity division director. “The challenging part is always in the first couple days whenever this happens,” said Barrett, who oversaw communications and cyberspace for Operation Unified Response, the U.S. military's mission in Haiti following the 2010 earthquake. “The team is coalescing about how they want to operate, and they're getting their feet wet, getting new accounts on networks ... [getting] their logins.” Cybersecurity aboard the ships is also complex. Both ships have 1,000 beds, 12 operating rooms, blood banks, labs, medical devices and a multitude of other “internet of things” devices connected to hospital beds. According to a 2018 survey by health care IoT security company Zingbox, each bed can have as many as 10-15 IoT devices. “They have to be cyber-ready, or the mission of the Mercy is considered [degraded],” said Dean Hullings, global defense solutions strategist at Forescout, which handles Comply to Connect — a Defense Department framework created to ensure the cybersecurity of new devices — for the USNS Mercy. Ensuring connectivity For the devices to function, they need connectivity. When the ships arrived in ports in late March, technology firm CenturyLink “donated” connectivity to the Mercy, while Verizon provided connectivity to the Comfort. Former and current Navy officials told C4ISRNET that adequate broadband is the most challenging IT consideration faced by these ships. “Obviously you're going to be transferring imagery of X-rays or things like that that are more dense and require a ... higher data rate, so that bandwidth in port is important,” Barrett said. And with the introduction of patients, bandwidth needs become more complex. “The greatest communications challenge we are going to face during this deployment is the increased need for patients to communicate off the ship during their stay,” Tom Van Leunen, a spokesman for Military Sealift Command, told C4ISRNET. “Our hospital ships are designed to support official communication for the ship's crew and embarked medical community to complete their job. Adding a capability for patients to reach loved ones increases the risk of saturating the bandwidth off the ship.” Aboard both ships, the Navy doubled the bandwidth, he said, adding that Navy personnel also set up separate networks for patients' communications. While this solves one networking problem, it can also create an increased cybersecurity risk. Securing the ships Cybersecurity on the hospital ships follows the same standard practices as the rest of the Navy fleet. Since those aboard are largely Navy medical staff and personnel, they know what activities are acceptable on the network, Barrett said. “You can't just go and plug anything into that network because of potential vulnerabilities that that system may bring that could affect not just the ship, but remember, the ship is then connected to the rest of the [Department of Defense Information Network],” Barrett said. “So risk by one is shared by all.” ForeScout's Hullings said a hospital environment “epitomizes” why the Comply to Connect program is necessary. The ship has desktops, servers, routers, printers and other networks equipment, as well as mobile devices, such as tablets, that health care providers use to track patient care. “The truly unique stuff is the mission systems of the hospital, like X-ray machines, MRI machines, the beds themselves in the post-operative recovery rooms, that are all sensors. And they are all passing data. They have to be protected,” Hullings said. A spokesperson for the Navy told C4ISRNET that the ships are prepared for the cybersecurity challenges associated with their missions, but declined to address what additional cybersecurity challenges are introduced with the addition of private citizens. “These ships have routinely deployed in humanitarian assistance missions such as Pacific Partnership (USNS Mercy) and Continuing Promise (USNS Comfort) that required them to operate in partner nation ports, with foreign national patients being brought to and from the ship,” said Cmdr. Dave Benham, a spokesman for the Navy's 10th Fleet. “In all operating locations, we take appropriate precautions to keep our networks secure, and we do not discuss specific measures in order to protect operational security.” Cybersecurity on the hospital ships follow the same protocols as any other Military Sealift Command ship, said Benham. “Protecting our networks is a continuous challenge, and the overarching concern is to ensure that the right information gets to the right place at the right time with the right level of protection,” he explained. Cybersecurity aboard the hospital ships follow similar efforts to those recommendations made by the Centers for Disease Control and Prevention: Wash your hands. “It's ‘wash your hands' with your computer, too,” Barrett said. “Do good hygiene with your computer.” https://www.c4isrnet.com/it-networks/2020/04/21/for-the-navys-hospital-ships-networking-is-yet-another-challenge/

  • Build a fleet, not a constituency

    Build a fleet, not a constituency

    By: Bryan Clark and Timothy A. Walton The U.S. Navy's long-awaited award of a contract to design and build a new class of frigates has brought with it calls to dramatically expand the planned class of 20 ships to a fleet of 70 or more hulls. Like recent congressional efforts to build more of today's amphibious ships or destroyers, these recommendations risk putting the Navy on an unsustainable path and could fail to influence Chinese or Russian adversaries the U.S. fleet is intended to help deter. The Navy clearly needs guided-missile frigates. By bringing comparable capability with less capacity, frigates will provide a less expensive alternative to Arleigh Burke destroyers that are the mainstay of today's U.S. surface fleet. Freed of the requirement to conduct almost every surface combatant operation, destroyers would have more time to catch up on maintenance and training or be available to conduct missions demanding their greater missile capacity like Tomahawk missile strikes or ballistic missile defense. However, the frigate's size — less than a destroyer, more than a littoral combat ship or corvette — also limits its ability to support U.S. Navy wartime operations. Frigates like the Franco-Italian FREMM can conduct the full range of European navy operations such as local air defense, maritime security and anti-submarine warfare, or ASW. But the American FREMM variant will not have enough missile capacity for large or sustained attacks like those conducted by the U.S. Navy during the last several years in the Middle East, or like those that would be likely in a conflict with China. And although they could defend a nearby ship from air attack, the planned U.S. frigates could not carry enough longer-range surface-to-air interceptors to protect U.S. carrier and amphibious groups, or bases and population centers ashore. Proponents argue frigates' capacity limitations could be mitigated by buying more of them, better enabling distributed maritime operations and growing naval presence in underserved areas like the Caribbean and Arctic. In a post-COVID-19 employment environment, accelerating frigate construction could also create jobs by starting production at additional shipyards. Although they cost about $1 billion each to buy, the money to buy more frigates — at least initially — could be carried in the wave of post-pandemic economic recovery spending. But after a few years, that spigot will likely run dry, leaving the Navy to decide whether to continue spending about half the cost of a destroyer for a ship that has only a third as many missiles and cannot conduct several surface warfare missions. The more significant fiscal challenge with buying more frigates is owning them. Based on equivalent ships, each frigate is likely to cost about $60 million annually to operate, crew and maintain. That is only about 25 percent less than a destroyer. For the U.S. Navy, which is already suffering manning shortages and deferring maintenance, fielding a fleet of 70 frigates in addition to more than 90 cruisers and destroyers will likely be unsustainable. Instead of simply building more frigates to create jobs and grow the Navy, Department of Defense leaders should determine the overall number and mix of ships it needs and can afford within realistic budget constraints. The secretary of defense recently directed such an effort, which continues despite the impact of the COVID-19 pandemic. This commentary's authors are participating in the study. As recommended in a recent study, instead of buying more frigates to expand the fleet's capacity, the Navy would be better served by adding missile-equipped corvettes like those in European or Asian navies. These ships could carry as many missiles as the Navy's planned frigate but would not incorporate capabilities for area air defense or ASW. The smaller size and reduced capability of corvettes would reduce their sticker price to about one-third that of a frigate, and their sustainment cost to about a quarter that of destroyers. The lower price for corvettes would allow more of them to be built and deployed, where they could team with other surface forces to provide additional missile magazines that could be reloaded by rotating corvettes to rear areas. In peacetime, corvettes would enable the Navy to expand presence and maritime security to underserved regions and provide more appropriate platforms for training and cooperation. Frigates will still be needed, even with a new corvette joining the U.S. fleet. Frigates would replace destroyers in escort operations to protect civilian and noncombatant ships, like supply vessels. They would also conduct maritime security operations in places such as the Persian Gulf or South China Sea, where piracy, trafficking and paramilitary attacks occur. Most importantly, frigates would lead ASW operations, where their towed sonar systems could be more capable than the systems used by current destroyers. Although ASW is an important naval mission, buying more frigates than planned to expand the Navy's ASW capacity is unnecessary and counterproductive. The Navy could gain more ASW capacity at lower cost and with less risk to manned ships by complementing its planned 20 frigates with unmanned systems including fixed sonars like SOSUS, deployable sonar systems that sit on the ocean floor, unmanned surface vessels that tow sonars and trail submarines, and unmanned aircraft that can deploy and monitor sonobuoys or attack submarines to suppress their operations or sink them. The U.S. Navy is at the beginning of a period of dramatic change. New technologies for autonomy, sensing, weapons and networking are enabling new concepts for naval missions at the same time fiscal constraints and pressure from great power competitors are making traditional approaches to naval operations obsolete or unsustainable. The Navy's frigate award is a great start toward the future fleet, but the Navy needs to take advantage of this opportunity and assess the best mix of ships to field the capabilities it needs within the resources it is likely to have.
