    TEWKSBURY, Mass. — Raytheon Co.’s AN/SPY-6(V) radar continues to demonstrate its integrated air and missile defense capability through exceptional performance against multiple targets, the company said in an Oct. 10 release.

    The radar detected, acquired and tracked multiple targets from the U.S. Navy’s Pacific Missile Range Facility, Kauai, Hawaii. Capitalizing on two unrelated exercises conducted nearby in mid-September, SPY-6(V) not only tracked multiple threats simultaneously, but also a ballistic missile through intercept, for the first time.

    Raytheon’s SPY-6 continues successful testing at the U.S. Navy’s Pacific Missile Range Facility.

    “AN/SPY-6(V) continues to impress through consistent performance against complex, surrogate threats,” said U.S. Navy Captain Seiko Okano, major program manager for Above Water Sensors, Program Executive Office, Integrated Warfare Systems. “With production now underway, we’re progressing — with confidence — toward delivery of this exceptional, game-changing radar, which will transform our naval capabilities for decades to come.”

    The SPY-6(V) program has met all milestones, ahead of or on schedule, since its inception in January 2014. The radar has amassed a track record of performance, demonstrating its multimission capabilities against an array of single and multiple simultaneous targets throughout the Navy’s extensive testing program and against various targets of opportunity. Now in production at Raytheon’s advanced Radar Development Facility, AN/SPY-6(V) remains on schedule for delivery to the first DDG 51 Flight III, the future USS Jack H. Lucas, in 2019.

    AN/SPY-6(V) provides greater range, increased accuracy, greater resistance to environmental and man-made electronic clutter, higher reliability and sustainability than currently deployed radars. The radar’s demonstrated sensitivity provides greater coverage for early and accurate detection which optimizes the effectiveness of the Navy’s most advanced weapons, including all variants of Standard Missile-3 and Standard Missile-6.

    Nah, it's pretty much the same as the MFSTAR or SAMPSON.

    Only new thing i see is modularity . but that brings complicacy and human effectiveness into the equation. I hope they come up with a true anti missile system onboard naval assets against super manuverable russian and chinese cruise missiles and gliders.

    Both radars do exactly the same thing. Both radars are multifunctional and scalable. If you haven't seen the Kolkata class yet, I would recommend looking it up now, you will notice that it doesn't have dedicated fire control radars, like the one you will find on Shivalik class. The MFSTAR does everything.

    Watch this:

    In case of radar systems, black-and-white judgments should not be made on the grounds of being AESA, Scalable and/or Digital Beam Forming. There are many variables involved which influence sensitivity and range of a radar system.

    MF-STAR is a peer of AN/SPY-1D in performance as per Deagel; both operate in S-band. However, USN is uplifting AN/SPY-1D to AN/SPY-1D(V) standard on Flight I and Flight II destroyers; this standard enable superior clutter rejection and advanced BMDS capability (to defeat Chinese DF-21D type threats).

    MF-STAR is Digital Beam Forming and Scalable but similarities with AMDR end here.

    "The MF-STAR uses four 3 x 3-metre fixed-array faces (each weighing 1,500kg) based on a modular tile-array architecture (with each tile containing 16 Gallium Arsenide transmit/receive modules) to allow for scaleability in the size of the antenna aperture."

    Source: http://trishul-trident.blogspot.com/2011/04/mf-star-deliveries-for-project-15a-ddgs_07.html

    Scalability logic of AMDR is different (the first of its kind).

    AMDR = combination of Radar Modular Assembly (RMA) components; each RMA is a self-contained radar in the box.

    [​IMG]

    AMDR incorporate a combination of S-band and X-band radar systems and RSC, and its transmit-receive modules are constructed with Gallium Nitride (GaN) semiconductor technology.

    "The AMDR consists of an S-band AESA radar for air and missile defense, an X-band radar for horizon search, and a command and control integration center. The AMDR is the first radar built with Radar Modular Assemblies (RMA) building blocks, which allows for the radar to be scaled smaller or larger. The system’s Radar Modular Assemble (RMA) are 2’ x 2’ x 2’ radars that are scalable and will be able to fit different ships according to their mission. RMA blocks will use gallium nitride (GaN) which need less space, power, and cooling. The AMDR will be 30 times more sensitive than currently fielded radars on the Arleigh Burke Destroyers and can handle over 30 times the targets of the SPY-1.

    The AMDR may also have offensive capabilities, including the ability to perform electronic attacks with its active electronically scanned array (AESA) antenna. The ASEA array could attack airborne or surface targets by using “tightly directed beams of high-powered radio waves” that could blind adversaries’ assets."

    AMDR is the most powerful and sophisticated radar system out there, for use in Naval platforms. A breakthrough in design, and redefines scalability.

    The MFSTAR is scalable. So that means if you want 6x6m, you can easily get that. The MFSTAR on Kolkata is bigger than 3x3m.

    This radar in a box thing is how the MFSTAR is also designed. And unlike AMDR, it is actually operational. The base tech of the MFSTAR is the EL/M 2084. It comes mounted on jeeps, trucks and corvettes, frigates, destroyers, carriers etc. The Iron Dome has the smallest version and the Vikrant has the largest version. So the MFSTAR is basically 4 large EL/M 2084s radars.

    Here's the same radar for the Iron Dome, called mini-MMR.
    [​IMG]

    If you get yourself a bigger ship than the Kolkata class, then you can get a 6x6m array as well.

    The AMDR with S band or X band is a compromise. It's basically just 2 different radars, and is a ship design compromise.
    [​IMG]

    The MFSTAR doesn't need such a design. The single S band array handles everything by itself. Primarily because it's mounted on top of the mast, unlike the AMDR. If the MFSTAR on Kolkata was also below the bridge, we would have needed an X band radar on top of the mast.

    Btw, the MFSTAR is simply assumed to be the equivalent of the SPY-1, but it's not. It exceeds the capabilities of the SPY-1 by a huge margin. Primarily because it's AESA. The MFSTAR can pick up ballistic targets from much further away than the SPY-1 can. The SPY-1 has to split resources to perform transmission and reception, whereas the MFSTAR being digital can perform both at the same time with all its T/R modules. So it's way, way better than the SPY-1.

    Anyway, the AMDR's bigger size is necessary for BMD. You can't expect the smaller Kolkata class to carry a 6m array. The AMDR is meant for ship classes that weigh 12T or more. So it's not the radar that is better, it's the ship that is better. Stick a 6m MFSTAR on the new American destroyers and get the same capability if necessary. The range of the 3m version itself is well beyond 400Km.

    Did I argue otherwise?

    Provide evidence.

    AESA radar are scalable in general (T/R modules can be increased or decreased).

    [​IMG]

    [​IMG]

    NOTE: RMA blocks architecture is not a prerequisite for scalability.

    ---

    RMA blocks in AMDR for reference:-

    [​IMG]

    "It is the first scalable radar, built with Radar Modular Assemblies - radar building blocks. Each RMA, roughly 2' x 2' x 2' in size, is a standalone radar that can be grouped to build any size radar aperture, from a single RMA to configurations larger than currently fielded radars." - Raytheon

    [​IMG]

    "The scalable antenna is composed of 2 ft - 2 ft - 2 ft radar module assembly (RMA) building blocks, with four linereplaceable units (LRU) per RMA. Each LRU can be replaced in less than 6 minutes." - Eli Brookner

    AMDR will be operational soon, with Flight III destroyers.

    Thank you. Doesn't prove that these radar systems incorporate RMA blocks like in AMDR.

    Do you understand the concept of dual-band frequency radar systems?

    What you see on the surface is AMDR-C (for volume search) and AMDR-X (for horizon search) but everything is integrated on the backend (unified management and processing).

    "Most current warships use two different types of radars to scan large areas and for focused targeting. The data from these separate pieces of equipment is integrated in a ship’s combat system. Dual-band radars combine both sensor systems with the same electronics and software. This combination provides a ship’s combat system with a single data stream. The radar itself can mix its antennas to meet specific situational requirements."

    You are jumping to conclusions without adequate knowledge. Do not speculate.

    There is solid evidence of AN/SPY-1D(v) equipped platforms enabling interceptors to defeat sea-skimming cruise missiles, ballistic missiles and even hypersonic projectiles in exo- atmospheric conditions with extreme precision - some of the most difficult targets to track and engage. And there is hardly any destroyer out there which have showcased similar capabilities live (mostly theory).

    You also need to study the course of evolution of SPY-1 system (from Baseline C1 to Baseline C9); you will notice tremendous leap in capabilities over the course of time.

    [​IMG]

    [​IMG]

    Both AN-SPY-1B and AN-SPY-1D are multifunction, and do not have to split resources to perform transmission and reception.

    "An alternative approach to a full active array is to break the array into moderately sized subarrays which have their own electronics, and are then further combined afterwards to yield the full array. This is adopted for example in the AN/ SPY-1 AEGIS arrays, where sub-arrays of 16 elements each have copies of transmit-receive electronics."

    AMDR is revolutionary and better. This should not be an argument.

    2023-24. That's their date for IOC.

    MFSTAR does the same with just one band. As I said, it's about the placement of the radar.

    "No matter if it is a white cat or a black cat, a cat that can catch rats is a good cat."

    Just look at the Kolkata and tell me where's the dedicated fire control radar then.

    It's not speculation. How else do you think Kolkata gets fire control? MFSTAR performs all tasks, even fire control.

    Here's the Sa'ar 6.
    [​IMG]

    You can see that it only has MFSTAR on the main mast.

    Most destroyers do not need BMD capability. Even the US has only a few destroyers that can perform exo-atmospheric interception. The MFSTAR can also perform the same tasks, just that the Kolkata does not carry something like the SM-3. In fact, you can introduce SM-3 on any large MFSTAR ship, won't make a difference.

    The MFSTAR is way better than the latest SPY-1 variant. There is no comparison. Every face of the MFSTAR has more T/R modules than the SPY-1 does. And the MFSTAR's modules are active and digital. The base technologies of the SPY-1 itself is significantly inferior.

    They must split resources. These radars are not AESA, they are PESA. All PESAs have to split resources for transmit and receive.

    Nothing revolutionary about it when you look at other Europeans navies sporting the same kind of radar. And the MFSTAR is already an equivalent.

    Not an issue.

    USN is already superior to its peers.

    FYI:-

    "Kolkata-class is equipped with Thales LW-08 long range volume search radar, EL/M-2248 MF-STAR multi-mission radar and EL/M-2238 L-band STAR surveillance radar from Israel Aerospace Industries."

    Source: https://www.naval-technology.com/projects/kolkata-class-guided-missile-destroyers/

    MF-STAR is S-band only. It cannot offer X-band level target acquisition performance for airborne targets. And why a separate Thales LW-08 D-band radar to perform volume search in there?

    AMDR is dual-band; what you see on the surface is AMDR-C (for volume search) and AMDR-X (for horizon search) but everything is integrated on the backend (unified management and processing).

    AMDR effectively eliminates the need for installing another radar system on a vessel, for any end.

    You dodged my point.

    AMDR is the only radar system in existence with architecture of RMA blocks wherein each RMA block is an individual radar system. Time to come to terms with this reality.

    ???

    Do you understand the architecture of AEGIS?

    AEGIS = AN/SPY-1D(v) + MK 99 Fire Control System = Integrated Single Ship System

    Aegis is an integrated missile guidance system used on U.S. Navy and allied ships to protect the battle group. Using an S-band phased-array radar, the Aegis SPY-1 radar acquires and tracks multiple targets, such as planes and missiles, and defends against them. It operates as an integrated single ship system, as well as in a ship-to-ship network. - Raytheon

    AMDR is next-generation AEGIS.

    Once again, black-and-white comparisons are not advisable.

    Chinese DF-21D and DF-26 say hello.

    MF-STAR can develop a fire solution for Barak 8 but this interceptor does not have proven BMDS capability.

    I suppose you have had access to both? This is sweeping generalization on your part.

    FYI: https://www.quora.com/What-is-the-d...directions-simultaneously/answer/William-Keim

    How do you know? Are you privy to design of AN/SPY-1D(v)?

    Blah blah

    There is actual reality and then there is randomradio's fantasy.

    AMDR is a leap from MF-STAR in design (Dual-band and RMA blocks), sensitivity (37 RMA blocks = SPY-1D(v) +15 dB), target acquisition capabilities (of a much wider base of targets), and target engagement capabilities (can develop a fire solution for multiple interceptor types).

    The MFSTAR can easily provide many times better fire control than a fighter jet's X band radar.

    The L band's just a design option for us. All countries have their own designs for specific ships. Look up the Horizon class frigate and the Type 45 destroyer. They are no different from Kolkata.

    And then look at the Shivalik class. The aft radar is an Israeli S band, while the main mast has a Russian S band radar.

    I already told ya. You wouldn't be saying this if you actually know the utility of each radar. Where are the FCRs for the Kolkata class? Just look it up and tell me. Compare it with the older Arleigh Burkes, you will have your answer.

    Here's a nice big picture for you to check.
    [​IMG]

    If you want clues, then look at the Shivalik class.
    [​IMG]

    You don't get it. This doesn't matter. It is quite literally a useless capability, it's only purpose is advertisement. You can simply design any AESA radar system to do this. The only thing that matters is the plank design. You can easily build up from there. The Israelis use the same radar from Iron Dome to SPYDER-MR to Barak to Kolkata class to Vikrant class.

    The ship or the missile doesn't care whether the radar comes in multiple boxes or multiple planks without the boxes. It literally serves no other purpose after it is installed. LRU management happens at the plank level.

    Dude, MFSTAR does exactly that. It "literally" does exactly that. And with just one radar.

    As I said, just look at the Kolkata class and look for all the fire control radars, you will have your answer.

    Kolkata class isn't a BMD ship, although Barak 8 can be used against SRBMs. But the Barak 8ER will be able to stop MRBMs of the DF-21 class. Since it's in development, we won't know how effective it is for sometime.

    We don't consider the Chinese ASBMs a threat to our small ships yet. Even the Chinese have designed it for use against carriers, not against destroyers.

    Dedicated BMD ships are coming. We are in no hurry.

    Of course. It's all open source. Look it up.

    If you actually knew something about radars, you wouldn't be sitting here trying to convince me a PESA of the same size is better than a digital AESA which actually has more T/R modules.

    Lol, bro. You have no idea about radars. Both MFSTAR and AMDR are significant leaps from the old SPY-1. Right now, the MFSTAR used is simply smaller than the AMDR, but that has more to do with ship design than a problem with the radar. In terms of functionality itself, there is little difference between these two. It's all software controlled after all.

    Due to the death of the Zumwalt, the Americans are simply late to the game, nothing else.
