milstar: 3 oct 2018 Raytheon won. Lockheed Martin – lost Northrop Grumman – lost Raytheon builds the AN/TPY-2 X-band radar used by the land-based THAAD missile system, the 280 foot high X-band array on the floating SBX missile defense radar, and the large land-based ballistic missile Upgraded Early Warning Systems like the AN/FPS-108 Cobra Dane and AN/FPS-115 PAVE PAWS. On the S-band side, the firm builds the S-band transmitters for Lockheed’s SPY-1 radar on board existing American destroyers and cruisers. Unsurprisingly, Raytheon personnel who talked to us said that: “…leveraging concepts, hardware, algorithms and software from our family of radars provides a level of effectiveness, reliability and affordability to our proposed AMDR solution… The challenge for all the competitors will be to deliver a modular design. The requirements demand that the design be scalable without significant redesign… A high power active radar system requires significant space not only for the arrays themselves but also for the power and cooling equipment needed to support its operation. Finding space for additional generators and HVAC plants can be quite challenging for a backfit application. That is why power efficiency is a premium for these systems.” ------------------ Lockheed Martin – lost Lockheed Martin stepped into the competition with several strengths to draw on. Their AN/SPY-1 S-band radar is the main radar used by the US Navy’s current high-end ships: DDG-51 Arleigh Burke class destroyers, and CG-47 Ticonderoga class cruisers. Lockheed Martin also makes the AEGIS combat systems that equips these ships, and supplies the advanced VSR S-band radar used in the new Dual Band Radar installations on board Ford class carriers Nor were they devoid of X-band or ballistic missile defense experience. Their L-Band AN/TPS-59 long range radar has been used in missile intercept tests, and is the only long range 3D Radar in the Marine Air-Ground Task Force. It’s related to the AN/TPS-117, which is in widespread service with over 16 countries. Then, too, the firm’s MEADS air defense technology demonstrator’s MFCR radar will integrate an active array dual-band set of X-band and UHF modules, via a common processor for data and signal processing. It was a strong array of advantages. In the end, however, it wasn’t enough. ================================================ The destroyer ‘Jack Lucas’ will join the Navy’s fleet in 2024. The vessel is modelled after the 73 Arleigh-Burke class destroyers already in service, but it will be a very different, more capable killer than its predecessors. ‘Jack Lucas’ gets its extra punch by adding Raytheon’s newly developed AN/SPY-6 air and missile defense radar. The Flight III is a major overhaul of the guided-missile destroyer. It required a 45 percent redesign of the hull, most of which was done to accommodate the AN/SPY-6 and its formidable power needs he AMDR-S provides wide-area volume search, tracking, Ballistic Missile Defense discrimination, missile communications and defense against very low observable and very low flyer threats in heavy land, sea, and rain clutter. In addition, the AMDR-X provides horizon search, precision tracing, missile communications, and final illumination guidance to targets. The AN/SPY-6 is 30 times more sensitive than its predecessor, its additional sensitivity supercharges the vessel’s capabilities in anti-air warfare and ballistic missile defense. April 17/14: SAR. The Pentagon releases its Dec 31/13 Selected Acquisitions Report external link. AMDR enters the SAR with a baseline total program cost estimate of $5.8327 billion, based on 22 radars. https://www.defenseindustrydaily.com/amdr-raytheon-wins-dual-band-05682/ For the Flight III Burke-class destroyer's SPY-6(V) AMDR will feature 37 RMAs. The new radar will be able to see targets half the size at twice the distance of today’s SPY-1 radar. The AMDR will have four array faces to provide full-time, 360-degree situational awareness. Each 14-by-14-foot face is about the same size as today’s SPY-1D(V) radar. =================== https://www.militaryaerospace.com/articles/2018/04/shipboard-radar-amdr-destroyers.html The AN/SPY-6(V) radar also is reprogrammable to adapt to new missions or emerging threats. It uses high-powered gallium nitride (GaN) semiconductors, ============================== distributed receiver exciters, adaptive digital beamforming, and Intel processors for digital signal processing. The new radar will feature S-band radar coupled with X-band horizon-search radar, and a radar suite controller (RSC) to manage radar resources and integrate with the ship’s combat management system.
