All Fregat radars have the same shape antennae (the ones in the picture are definately identical) and serve the same purpose there would be no reason to have two different Fregat variants on one ship.
Having two redundant systems isn’t always a bad idea. Perhaps Fregat has a high component failure rate? You could always use one while the other is offline.
No s**t, Sherlock?
True, before it went belly up in 2004, the Nederlandsche Verenigde Scheepsbouw Bureaus – bankrupted 2004 a.k.a. N.V. VEREBUS- were an RDM (Rotterdamse Droogdok Maatschappij) daughter/workcompany. However, the origins of Nevesbu date back to 1935 when B.V. Nederlandse Verenigde Scheepsbouw Bureaus was founded to create a knowledge centre on naval design and engineering. NEVESBU was founded to ensure input of Dutch dockyards and machine industries like Stork B.V. in naval design for the Dutch navy and exports. Nevesbu is a company of Naval Architects and Marine Engineers. By contrast De Schelde is a yard, not a design bureau. Different animal.
And I didn’t say that the Nevesbu design was the same. What’s with that chip? The pic showns the design I was referring to but, IIRC, there was also a smaller stealthy corvette design to accompany this one, which may (or may not) be the basis for the above project…
The “chip” came from Nevesbu’s site – before the bankruptcy. The vessel depicted is the 122m, 4000 ton “stealthy update” on the M-class frigates. Nevesbu also promoted a “stealthy update” on the Indonesian Fatillah class corvettes at the same time.
More recently, Nevesbu marketed a different “Falcon class” corvette against Schelde’s Sigma class, and lost both in Indonesia and the Netherlands. The design was also marketed to India for its Coast Guard.
Here is an image of Nevesbu’s updated Fatillah class from a few years ago – which has apparently has nothing to do with the new Schelde design.
The Nevesbu “Falcon design corvette” also shares no obvious visual similarities with the Schelde design that this thread is about.
Yes please do. I remember former Nevesbu had a design study for a more stealthy version of the M frigate some years ago, maybe this is a further or similar development. But at this point I don’t think it is more than a design study. But I would love to learn more about it!
Nevesbu is a design bureau, and is often in competition with Schelde. The 4,000 ton Nevesbu frigate design was far more conventional than this “Combatant 12717.”
Its says Artists impression naval ship by courtesy of “De Schelde Shipyard”, whic Royal Schelde doesn’t have anuthing on it on their site. Royal Schelde is part of Daemen group, and their website doesn’t list anything similar either. So, certainly not being build, not ordered, probably not even proposed.
Royal Schelde’s website isn’t updated very frequently. I know fully well that there aren’t any domestic orders for a ship fitting this description, but many naval designs are marketed to potential export customers.
I am looking for information on the nuclear powered PA2 proposal before it was dropped in favour of a conventionally powered vessel. As I understand it the vessel was basically an enlarged and improved CdG, possibly with ba doubled up powerplant in comparison to that vessel with a displacement somewhere around 60,000 tonnes. If anybody has any info or even better pictures I would be very grateful.
Thanks in advance sealord.
There isn’t that much information about the definitive “Juliet” configuration that came before the CV-F partnership.
In fact, the only drawing/deckplan that I’ve seen is a badly photoshopped drawing of the CdeG that was passed off as the PA2.
That does look like a cool design. It even looks stealthier than the Visby class. Hopefully they are building it. The front looks a little strange, is that an opening? Maybe a VLS system? I don’t see a turret, although I see the smaller CIWS turret in the back, looks like the Millenium gun.
—–JT—–
There is a gun turret forward, but it is “concealed.”
I don’t know whether this is meant to be the 155mm AGS, or a much smaller system?
Perhaps this profile will give a better view of the gun installation.
And here something I found while looking around, but didn’t really find the right topic to put it in.
The article accompanying it was in native language so that wouldn’t be of any use to you. Sorry about the bent nose, it was on the wrong side of the book 😉
Do you have any other details about this Schelde concept? Did the image come from an article or an advertisement?
The design itself isn’t entirely new, as it has been displayed by Thales to promote their integrated mast design.
Perhaps I should start a thread dedicated to this stealthy ship?
Grumman’s Super 7 would have looked like what the FTC-2000 is today except it would be a single seater.
I have always thought that the J-7MG was originally conceived as a testbed for the Super 7’s wing and the FTC-2000 is directly descended from the Super 7 program.
Of course, the FTC-2000 has a slightly different wing planform than the J-7MG…..
Quite a lot might have been possible: http://www.quarry.nildram.co.uk/Alternative%20RN.htm

I might agree with many of your conclusions, but I do have to wonder about some of the real technical factors at play.
For instance, was Sea Wolf VLS development protrated by technical issues or funding issues? In hindsight, the VLS concept is intuitively superior.
I do have to disagree with you when it comes to the topic of marine gas turbines and the number of shaft a warship should have.
As far as I know, the Marine Spey is hardly a straightforward derivation of the early 1960s Spey turbofan. It occurs to me that the development of the Marine Spey depended on the core of the later Tay turbofan, which itself was Spey derived.
It should be remembered that development of amarine gas turbine is dependant on development of the aero-engines it is based on, and not the other way around. The development of the Concorde’s Olympus 593 resulting in a Marine Olympus with nearly twice the original output.
I would also disagree with your suggestion that Invincible class carriers should have had 3 or 4 shafts. Multiple shafts invite vibration issues and sometimes it is better to resort to gearing than to trail unpowered shafts. Thankfully, we now live in the age of massive waterjets and Mermaid podded propulsors.
To put this in perspective, it appears that at this point total J-10 production is greater than total Eurofighter production?
That is a sad commentary on European defense planning and funding.
* Salut has already publicly disclosed at least as many as 154 engines has been delivered from 2002, the last 100 engines ending this month. The last 100 engines include TVC and uprated thrust (AL-31FNM-1, 13,200kg thrust with the nozzle designed by Klimov). This does not count an undisclosed number of engines delivered prior starting 2002 which were meant for prototypes and preproduction planes. The Russians have described the second version of the J-10 as “Super 10”. At this point, its clearly documentable from Salut that the J-10 development has indeed entered a second stage intended to achieve supermaneuverability. I don’t think I need to post these articles again and again in front of people who selectively preen evidence only to fit how they want to “feel” good.
As long as the Chinese depend on the Russian for engines, we will have a way of tracking J-10 production totals.
What happens when production shifts to the domestic WS-10 turbofan?
We might lose our ability to track J-10 production totals?
Assuming that the WS-10 is only equivilent to the AL-31FNM-1, it will still represent a breakthrough for the Chinese aviation industry. Production of the J-10, and possibly even the license produced “J-11,” would be limited only by production capacity for the domestic turbofan.
I’m not entirely sure that I believe there are three separate and complete production lines for the J-10, but I wouldn’t be surprised…..
Is possible for “boreis” SSBNs to carry Yakhonts in their 650mm TT? Somewhere I read that the Vanguards SSBNs carries sub-harpoons.
Firing a missile out of a torpedo tube requires a far more rugged airframe than firing a missile out of a verticle launch tube.
This is why the Tomahawk Block IV costs half as much as the Block III. Of course, all late production U.S. submarines have verticle launch capability.
Klub is apparently meant to be fired from a torpedo tube, much like earlier Tomahawks. I have no idea about Yakhont or Brahmos.
What was there to stop the RN using the rotating drum as a VLS similar to the Soviet SA-N-9 with the rotating drum firing out of a single apeture rather than feeding them to the trainable launcher or even making the whole drum a VLS equivalent to the Mk41 or Sylver but in service far sooner than any of these.
Britain pioneered the VLS concept with Sea Wolf, although the concept wasn’t fielded in a timely manner.
The Russian rotary fed VLS also remains unique. It is hard to judge Soviet era concepts, especially when an attempt is made to compare them with their western equivilents.
Let me remind you that talked about modern destroyer designs and I mentioned aircraft carrier size ships (the only usefull nuclear powered warships today) and that ment nuclear steam as well. But now that you brought the nuclear powered ships, I must point out that the ammount of thrust gained form the reactors is rather low compared to the size and complex of the whole system. The thrust-to fate ratio is so low that there is no reasonable means to fit in ships smaller than US super carriers. Even the French De Gaulle is considered to be too small for the nuclear propulsion and thus (among few other shortcomings of the design) have led French to go for conventional design with their PA2.
It is worth noting that the last entirely French proposals for PA2 were conventional and steam powered. Only the politically motivated decision to join the CV-F program shifted the PA2 to gas turbine propulsion. Of course, there was never any doubt that the CV-F was going to gas turbine powered….and the current promotional efforts of Rolls Royce have determined many aspects of the final CV-F.:)
There were many things wrong with the CdeG, and French reactor technology doesn’t match that the United States. In truth, the CdeG should have been stretched 20 meters and should have had reactors with 50% greater output.
yes i agree… but oh my my operational fifth generation? please dont exxagerate.
by saying operational fifth generation your saying J10 >> eurofighter , rafale su 30 MKI etc etc etc and == F22 geez… its a 4th generation its not even 4.5 th gen .
I would probably lump the J-10 together with the Eurofighter, Rafale and Gripen. I would be inclined to say that all of the “Eurocanards,” the J-10, the LCA and even demonstrators like the ECA, the X-31 and Lavi together in the same generation.
The F-22 and F-35 don’t fit neatly into any attempt at categorization.
It is clear that any Su-27 derivative belongs to the older F-14/15/16/18 generation.
