Four nations have selected Lockheed Martin’s Solid State Radar (SSR) technology to provide front-line defense with its cutting-edge air and missile defense capabilities, the company announced.
These four nations – USA, Spain, Japan, and Canada – 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 U.S. 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 was designated by the U.S. Government as AN/SPY-7(V)1.
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 SPY-7 technology consists of a scalable and modular GaN-based “subarray” radar building block, providing advanced performance and increased efficiency and reliability to pace ever-evolving threats.
The Solid State Radar 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.
The 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 (AWS), the world’s premier air and missile defense combat suite.
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 also be utilized for future radar programs including Aegis Ashore Japan, Canadian Surface Combatant and MDA’s Homeland Defense Radar in Hawaii.
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. The 24 platforms 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. Missile Defense Agency (MDA) selected Lockheed Martin to develop the Long Range Discrimination Radar (LRDR) in 2015 with an on-track delivery set for 2020. The LRDR formed the basis of SSR.
LRDR, a Gallium Nitride (GaN)-based, solid-state Active Electronically Scanned Array (AESA) early-warning radar, is currently under construction at Clear Air Force Station, Alaska, and is scheduled for an on-time delivery in 2020.
The LRDR radar system will serve as a critical sensor within MDA’s layered defense strategy to protect the U.S. homeland from ballistic missile attacks. It will be part of the United States’s Ground-Based Midcourse Defense (GMD) anti-ballistic missile system.
In 2018, the MDA awarded Lockheed Martin a contract to design, manufacture and construct the Homeland Defense Radar-Hawaii (HDR-H) in Oahu, Hawaii. The HDR-H radar will provide autonomous acquisition and persistent precision tracking and discrimination to optimize the defensive capability of the U.S. Ballistic Missile Defense System (BMDS) and counter evolving threats.
The Japanese Ministry of Defense selected SPY-7 radar for two planned land-based Aegis Ashore installations in 2018.
SPY-7 and Aegis Ashore will defend against ballistic missile threats and provide continuous protection of Japan. SPY-7 provides several times the performance of traditional SPY-1 radars and the ability to engage multiple targets simultaneously with the latest proven missile 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 the 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 frigates.
The program will make Canada the owner of the world’s second-largest Aegis fleet, and the SPY-7 radar variant will enable CSC to conduct highly advanced maritime missions for decades to come.
