The world’s latest generation solid-state radar technology, formerly known as Lockheed Martin’s Solid State Radar (LM SSR), has been designated as AN/SPY-7(V)1 by the United States government. The designation of AN/SPY-7(V)1 is a direct reflection of the maturity and capability of Lockheed Martin’s solid-state radar technology.
The Japanese Ministry of Defense selected AN/SPY-7(V)1 for two planned Aegis Ashore installations in 2018. Additionally, variants of AN/SPY-7(V)1 will be used by the Royal Canadian Navy for the Canadian Surface Combatant program and the Spanish Navy for the upcoming F-110 frigate program.
«Lockheed Martin’s solid state solution meets the mission now and is flexible to adapt to the evolving threats of the future», said Paul Lemmo, vice president and general manager at Lockheed Martin. «This new designation solidifies our ability to provide the most technically advanced capabilities our warfighters require».
AN/SPY-7(V)1 is a modular and scalable solid state radar, allowing for continuous surveillance and protection. It will be fully integrated with the Aegis Combat System, providing advanced technology for future ship classes.
With 50 years of constant evolution and innovation, Lockheed Martin has a trusted history of producing, integrating and delivering radars and combat systems. Lockheed Martin and the Aegis Combat System continue to keep pace with evolving integrated air and missile threats, introducing new capabilities to create the latest generation of advanced solid state technologies, integrated with the Aegis system, to provide world-class defense and ensure future safety and security.
Raytheon Company has been selected to provide the U.S. Army with their next generation, 360-degree capable radar – the Lower Tier Air and Missile Defense Sensor (LTAMDS). Raytheon will receive more than $384 million to deliver six production representative units of the advanced LTAMDS radar under an Other Transactional Authority U.S. Army agreement. LTAMDS is a new radar that will ultimately replace the current U.S. Army’s Patriot radars. It will operate on the Army’s Integrated Air and Missile Defense (IAMD) network.
«Our clean-sheet approach to LTAMDS reinforces Raytheon’s position as the world’s premier air and missile defense radar capability provider», said Ralph Acaba, President of Raytheon Integrated Defense Systems. «Patriot is the world’s leading, combat-proven air and missile defense system, and 17 nations have procured 240 radars from Raytheon. With the U.S. Army’s approval, these Patriot partners will have the opportunity to add Active Electronic Scanned Array, 360-degree capability to their inventory, extending the life of their systems for many decades».
Raytheon’s winning LTAMDS solution is a 360-degree, Active Electronically Scanned Array (AESA) radar powered by Raytheon-manufactured Gallium Nitride (GaN), a substance that strengthens the radar signal and enhances its sensitivity. Over the past two decades, Raytheon has invested significantly in AESA GaN technology and advanced manufacturing capability, positioning the company as the global leader in advanced GaN technology and product development.
«For decades, we have invested in radar technology to address our customer’s most pressing needs. As a result, we’ve developed the ability and capacity to provide the Army an advanced capability on an accelerated timeline», said Tom Laliberty, vice president of Integrated Air and Missile Defense for Raytheon Integrated Defense Systems. «Our in-house advanced manufacturing capability and strong supplier network will enable us to meet the Army’s urgent material release requirement».
Raytheon assembled a team of suppliers who played a strategic role in developing Raytheon’s LTAMDS solution. They are:
Lockheed Martin has been awarded a $281 million contract by the United States Army to develop the Sentinel A4 radar system.
Sentinel A4 is a high-performance modification of the Sentinel A3 (AN/MPQ-64A3) air and missile defense radar that will provide updates to improve the existing Sentinel capability against cruise missiles, unmanned aerial systems, rotary wing and fixed wing threats.
The new Sentinel A4 radar will provide improved surveillance, detection, and classification capabilities against current and emerging aerial threats in order to protect Army maneuver formations and high value static assets to include: command and control nodes, tactical assembly areas and geo-political centers. This needed capability will help protect our warfighters for the next 40 years.
«By leveraging our open scalable radar architecture and production efforts, we believe we provide the lowest risk and best value solution for the U.S. Army that will help protect our warfighters for years to come», said Doctor Rob Smith, vice president and general manager for Lockheed Martin’s Radar and Sensor Systems. «We have fielded numerous tactical Gallium Nitride (GaN) based radars beginning with the delivery of the TPS-77 Multi Role Radar to Latvia in 2018 and we are under contract with the Army to insert GaN into the Q-53 system».
Lockheed Martin, Ball Aerospace, and Kratos Defense & Security Solutions, Inc. were awarded a $7.2 million prototype agreement by the Defense Innovation Unit to develop a new Multi-Band, Multi-Mission (MBMM) prototype phased array as part of a broader initiative to modernize the existing Air Force Satellite Control Network and bring new technology faster to warfighters. MBMM enables multiple satellites to simultaneously connect with a single array antenna over multiple frequencies, a significant performance improvement compared to traditional single contact parabolic dishes.
The Lockheed Martin team is building prototype transmit and receive Electronically Steerable Arrays (ESA). Each array uses Ball’s advanced phased array technologies and supports L- and S-band frequencies initially. Signal processing is accomplished with Kratos’ digital Intermediate Frequency (IF) technology and cloud-enabled quantumRadio.
«MBMM is a smarter way to quickly and affordably scale satellite transmission while lowering long-term maintenance costs for the Air Force», said Maria Demaree, vice president and general manager of Lockheed Martin Mission Solutions. «Today, when a parabolic antenna goes down, it can take days to repair; with MBMM, it will take hours and won’t take the entire site offline – that’s a tremendous advantage».
Extensive industry research comparing the costs of parabolic antennas to phased arrays over time show that while parabolic antennas have a lower upfront cost, they become much more expensive to maintain. Phased arrays avoid the mechanical maintenance and keyhole effects of parabolic antennas while providing graceful degradation and electronic agility in matching aperture performance to constellation demands.
«One electronically steered antenna can replace multiple dishes, enabling better performance, connectivity and affordability», said Rob Freedman, vice president and general manager, Tactical Solutions, Ball Aerospace.
«Software modems deployed in virtual machines gives MBMM an advantage because it is easy to scale signal processing on a much faster timeline than previously», said Frank Backes, senior vice president of Kratos Federal Space.
Future operational MBMM systems will offer new cyber resilience while reducing long-term sustainment costs for the Air Force. MBMM may eventually support multiple orbits from Low Earth Orbit (LEO) to Geosynchronous Equatorial Orbit (GEO) and can perform multiple missions at the same time, including Command & Control (C2), launch pad and ascent operations, radar and mission data transmission. The Lockheed Martin/Ball team is one of several teams building prototypes for the government.
Lockheed Martin completed a rigorous Critical Design Review (CDR) on September 28 with the Missile Defense Agency (MDA) for the Long Range Discrimination Radar (LRDR), demonstrating compliance to all technical performance measures and requirements. The radar system will support a layered ballistic missile defense strategy to protect the U.S. homeland from ballistic missile attacks.
The MDA awarded the $784 million contract to Lockheed Martin in 2015 to develop, build and test LRDR, and the company is on track on an aggressive schedule to deliver the radar to Clear, Alaska in 2020. Teams from Lockheed Martin, MDA Sensors Directorate and the Command and Control, Battle Management, and Communications or C2BMC have worked interfaces closely to ensure seamless integration.
Successfully executing CDR validates that the LRDR system is ready to proceed into fabrication, demonstration, and test and that the hardware and software component have achieved Technology Readiness Level (TRL) 7 and Manufacturing Readiness Level 7.
With the completion of CDR, the program now begins the start of low rate manufacturing which began in October. In preparation for full rate manufacturing starting in mid-2018, Lockheed Martin will be utilizing production hardware in combination with prototype systems, tactical back-end processing equipment as well as tactical software to demonstrate system performance in an operational environment to achieve system TRL 7. Lockheed Martin will be performing a series of tests in the Solid State Radar Integration Site (SSRIS) including a closed loop satellite track test.
«We remain committed to support the MDA’s Ballistic Missile Defense and Homeland Defense Missions», said Chandra Marshall, LRDR program director, Lockheed Martin. «I am extremely proud of the team for their dedication and commitment to the successful execution of the LRDR program. This team has achieved every milestone, including this CDR, on schedule since contract award in 2015».
Marshall continued, «I am extremely pleased with the progress the entire LRDR team has made in the two years since contract award. With the success of CDR, LRDR is on track for Initial Operating Capability or IOC in 2020».
In addition to CDR, Lockheed Martin conducted a Facilities Design Review in October for the LRDR equipment shelter design. Lockheed Martin will run a full and open competition for the construction of the equipment shelter in Clear, Alaska and will begin construction of the shelter in the first half of 2019. The MDA team is preparing the site for Radar System Installation and checkout mobilization, constructing the Mission Control Facility and starting the foundation for the LRDR equipment shelter.
Similar to Lockheed Martin’s Space Fence radar system, LRDR is a high-powered S-Band radar incorporating solid-state Gallium Nitride (GaN) components. LRDR adds the capability of discriminating threats at extreme distances using the inherent wideband capability of the hardware coupled with advanced software algorithms.
LRDR is a strategic national asset of the MDA’s Ballistic Missile Defense System and will provide 24/7/365 acquisition, tracking and discrimination data to enable defense systems to lock on and engage ballistic missile threats, a capability that stems from Lockheed Martin’s decades of experience in creating ballistic missile defense systems for the U.S. and allied governments.
Lockheed Martin is well positioned to provide low risk, scalable radar solutions that address critical homeland defense needs; providing a persistent capability to keep pace with evolving threats, delivering unmatched discrimination capability in the Pacific architecture, and increasing the defensive capability of Ground Based Interceptors.
Work on LRDR is primarily performed in New Jersey, Alaska, Alabama, Florida and New York.
