USN Naval Sensor Designations

[Tzoli]

I've tried to collect and will collect the various Sensor designation the USN used and currently using but design/introduction dates are difficult to find!
I've found many date and mission on this site for the Radars though some seems to be not accurate (Stating the SPG-49 Talos and SPG-51 Tartar Radars was from the 1970's!)

[merriman]

A great resource. Easier that sleuthing things out of the Friedman books (which are the most authoritative documents I know of in the public domain).

 

[isayyo2]

I thought SPY-3/4 ran on unique software, not the regular Aegis Baseline.

 

[Tzoli]

There are soo many variations exists even just for naval vessels (Surface, Submersive, Combined) that this is going to be a long list.
Added a few more and slightly re-arranged the missing ones.

 

[Tzoli]

I thought SPY-3/4 ran on unique software, not the regular Aegis Baseline.

I don't know, sources says it's a Multi Function Navigation/Targeting Radar using the AESA Technology to support ship self-defense

The DDG-1000s do not have the Aegis Weapon System. They have the Zumwalt Combat System and Total Ship Computing Environment, which serve basically the same function as AWS.

Ford has a version of SSDS, also not AEGIS.

 

[Tzoli]

So AEGIS includes only the SPY-1 and 2?

 

[isayyo2]

So AEGIS includes only the SPY-1 and 2?

Plus SPY-6!

 

[TomS]

And SPY-7 https://www.lockheedmartin.com/en-ca/features/why-spy-7-is-the-world-s-most-versatile-radar.html

SPY-2 is the High Power Discriminator radar and it is a missile defense supplement to SPY-1,not a stand-alone multifunction radar.

AEGIS is a really complicated thing. There is the Aegis Weapon System (AWS), which is the core system of the AEGIS Combat System and includes the AEGIS Display System, the radar, the Command & Decision system, the weapon control system, the fire control system, and even the Standard missiles. But ACS also includes other ship systems that are not part of AWS, like the Tomahawk Weapon Control System, the ASW Combat System, etc.

And then we get to systems like the COMBATSS-21 combat system on the New FFGs, which is derived from ACS and uses ACS components and software but is not actually AEGIS.

 

[Tzoli]

Found this document describing and even containing some dimension data of the sensors of the late 1940's early 1950's!

Catalogue of Electronic Equipment-NavShips 900,116

For example it contains the dish dimensions of thr SPQ-2 Regulus I Guidance radar which I only know two photos of!

 

[Tzoli]

USN was the first to develop and install AEGIS type radars and combat system. Did the other navies developed similar system(s) or intended to develop? I've heard the Chinese might had developed something similar in the past few years, but what about the Soviets/Russians or the European Union? I doubt the RN alone had enough money but maybe in a joint venture? Japan and Korea seems to be content with the USN versions (Did they locally produce it or the USN exports the system to their navies?)

 

[Arjen]

There is Thales APAR / SMART-L MM. In use with UK, French, Danish, German, Italian, Dutch and South Korean navies.

Pretty much all first-tier navies have something similar. They don't all look the same, though. For example, the UK and Franco-Italian systems (in the Type 45 and Horizon ships, respectively) have the PAAMS air defense system, but they use rotating phased arrays with back-to-back panels instead of twice as many fixed panels, The UK also went with active phased arrays (SAMPSON) rather than passive arrays (EMPAR). The Franco-Italian effort has since adopted active arrays for newer ships (FREMM).

 

[Tzoli]

What about Russia? The Kirov as designed as US Carrier Fleet destruction but have very strong Anti Air could had benefited an AEGIS type system no?

 

[TomS]

What about Russia? The Kirov as designed as US Carrier Fleet destruction but have very strong Anti Air could had benefited an AEGIS type system no?

The Soviet were not close to fielding that sort of tech when the Kirovs were built. The last Kiev (Baku, later Gorshkov) and later carriers had a radar called Mars-Passat (NATO: Sky Watch) that was supposedly comparable to SCANFAR or maybe a simpler version of SPY-1, but it seems to have been very troubled and probably never worked as intended.

The Soviets saw the carriers rather then the cruisers as the logical platform for big air space battle management radars because it would help control their fighters in the absence of US-style AEW.

 

[Tzoli]

I know these are not Radars though quite big, but related to Northampton as well as to Wright, does anybody know the size/dimensions or designation of the huge Tropospheric Scatter antennas used by USS Northampton (Solid dish type) and USS Wright (Cage/Mesh like dish type)
Northampton:

Wright:

 

[T. A. Gardner]

The large antenna is associated with the AUTODIN communications system

The antenna is designated T/RIO-3

 

[Tzoli]

Thanks, still it will be very difficult to find info being google shows some KIA RIO Car and of course the city and cartoon results.
I have that drawing of the Wright but that antennae is just a sketch, it is much bigger then that.

 

[Tzoli]

Here is my drawing of it, based on photos, not sure how accurate size wise.

 

[T. A. Gardner]

I suspect the difference in the appearance of the antenna is due to this system evolving over roughly two decades before going out of use.

 

[Tzoli]

I wonder... Why did not the RIM-7 Sea Sparrow directors the Mark 95 "Bug Eye" and the manned Mark 115 receive an SPG-xy designation?

 

[Tzoli]

Does anybody know how the SR-2 radar antennae looked like?
I have a drawing which might be it but I'm not sure.
Here it is:


For example the SR or SR-1 looks like this:

While the SR-3 looks like this: (On USS Los Angeles CA-135)

Can somebody provide me info on what a Guthrie Antenna System could be regarding the SPS-24 Hemispheric Search Radar?

From Norman Friedman - Naval Radar:

SPS-24
An abortive 6cm hemispheric search radar, using the Guthrie antenna system: three stacked beams, not overlapping but 20° apart, nodding slowly at 15 nods per minute while the entire antenna rotated rapidly at 90rpm. The three 3,5°x6° beams were not uniformly illuminated (500kW in the lowest, 300kW in the middle, and 200kW in the upper beam), to achieve greatest range at low angles, corresponding to realistic aircraft altitudes. In this way a very light reflector, sized 6ft x 3,5ft and weighing 600lb, could duplicate the performance of the heavy SPS-3; in fact, SPS-24 was expected to provide accuracies of 0,5°in bearing and 1°in elevation, out to a range of 22nm and a maximum elevation of 60°.
This system was first proposed in 1951, but it was beaten out by the FRESCANs. The light antenna weight included stabilization; below-decks weight would have been another 5.000lb. SPS-24 might have gone aboard destroyer-escorts, but it failed to meet range requirements. Note that the high scan rate required very powerful pulses, since any target would meet relative4ly few of hem. SPS-24 was also designated P-4X, in a series of developmental electronic equipment.

Note the SPS-3 should look like this:

 

[Tzoli]

Another unknown antenna and radar for me is the Kelleher scanner used in the SPS-25:

SPS-25
An Abortive S-band lightweight hemispheric search radar, using Kelleher scanner producing 25 nods per minute while rotating at 15rpm. Early (1954) estimates called for a 500lb antenna providing elevation coverage from 0°to 86°, with a 50nm range on a 1m^2 target, gven 2,5MW pulses. Below-decks components were to be derived from the airborne AN/APS-20B (AEW) radar, and would have weighed only about 1.500lb, compared to about 8.000lb for CXRX. About a year later a table of air defense radars included a stabilized version, with an 1.100lb antenna and 600lb of below deck components, with elevation to 70° and a range of 40nm. Beamwidth would have been 4,4°x 12,5°, depending upon elevation. SPS-25 was also designated P-10X.
