On this topic, ... and looking at the latest models and images of the River Class, it is very difficult to dicern the details of the various antenna on the images (artists depictions) and models. How is that related to my Raven comment you may ask? Well, the Raven antenna (based on Ramses)...

From an old 'DEFENSECOOP' article ( link : https://defensescoop.com/2023/04/18/in-wake-of-fatal-collisions-navy-accelerates-software-defined-radar-deployments-on-surface-ships/ ) Note the words “as well as providing fire control quality track data to support surface gunfire,” The article goes...

Checking up on myself ... Having typed the above, I do note a couple of references ( here and here ) which equaate the AN/SPS-73(V) 18 as being the USA's Next Generation Surface Search Radar program , which matches the 'NGSSR' wording of the Congressional document. How much 'faith' can one...

As opposed to AN/SPS-73(V)18 for the Next Generation Surface Search Radar (NGSSR) that was referenced (but the model/make # not specified) in that Congressional document, I wonder if the exact radar could be a radar other than the AN/SPS-73(V)18? I note a Breaking Defense artice from Sep-2025...

After some time - Some speculation by me follows. Following the recent widely public news of the Royal Canadian Navy (RCN) purportedly adopting the BAE Mk 45 127mm gun and the MSI-DS Mk 38 Mod 4 30mm gun (in lieu of the Leonardo 127mm Volcano and Leonardo 30mm Lionfish guns), I note that the...

I note as of today, the Canadian Government page (FAQ) for the River Class destroyer now lists "LEED" instead of "Nulka". https://www.canada.ca/en/navy/corporate/fleet-units/surface/river-class-destroyer/fact-sheet.html I am a bit surprised that SIGINT (Strongbow - AN/SRD-506 - communications...

One speculative idea I had (speculation is the 'operative word' ) is the WFOV (wide angle field of view) EOSS could be the AN/SAY-3 I-Stalker, or a derivative of that (if such a derivative is available). And I speculate that the Mk20 could be the NFOV. As noted, I am speculating. I also...

I note Australia, with their Type-26 frigates (Hunter class) are planning to procure both Nulka and MASS Omnitrap (which has many different types of ECM munitions possible). As I note in the above quote, I would like to see the RCN also procure a chaff dispensing system such as MASS, where...

I note that the The L3Harris spec sheet ( https://www.l3harris.com/sites/default/files/2025-07/L3Harris-SPEIR-SPATIAL-sell-sheet-hr.pdf ) notes the SPEIR has these key elements: - Wide Field Sensor Subsystem ((WFSS) - implementation of WFOV (Wide Field of View) EOSS) , - Narrow Field Sensor...

Digging into SPEIR a bit, I note: SPEIR (Shipboard Panoramic Electo Optical Infrared) is the U.S. Navy’s program for a shipboard 360-degree passive EO/IR sensing capability. L3Harris Technologies’ SPATIAL system is a technical solution developed to meet this requirement. The system uses a...

Further to the above, I note again this Congressional record; https://www.govinfo.gov/content/pkg/CREC-2026-01-06/html/CREC-2026-01-06-pt1-PgS39-2.htm where it states (in the context of that Congressional record noting FMS to Canada for the Canadian Surface Combatant): What leads me to...

I found it interesting to read SPEIR is to be procured ( according to what is being sent to US congress). Here is a L3Harris marking brochure on SPEIR: https://www.l3harris.com/sites/default/files/2025-07/L3Harris-SPEIR-SPATIAL-sell-sheet-hr.pdf From that: The Shipboard Panoramic...

I think I found my "proof" (or rather - an independent source of information). I note the following US document that appears to confirm the change of the 127mm gun (date 23-Dec-2025 in a Report Delivered to USA Congress) ...

I think it fair to say we are all curious as to the ultimate fit of the 1st (and subsequent) batches of the River Class Destroyer. Most of us only have unclassified sources to rely on and not some 'contact' in DND nor in Industry. At least no contacts any more (after many decades having...

The new model is definitely interesing, and as noted suggests there are indeed changes. I note a model is just that - a model. Its degree of accuracy in depiction needs to be taken with some grains of salt. I believe more confirmation is appropriate to be certain, else we are still in the...
