Stealth ships steam ahead

I'm curious were you got this info, because to me it looks more like an American design rather than a French one. It looks like a quality job unlike what the French are making right now, right now the French want to build their ships to the commercial standard rather than the military standard. Which is a lot cheaper but not as advanced as the US is used to building their ships.

There not the only one, all recent british vessels are built to lloyds naval standards, providing more flexable but just as good designs as the old MOD standards. It also allows the classification societyies to be involved in their maintainance.

Below is a list of all the stealth ship designs i know of. I doubt it is complete (anyone know of any others?)

China has a couple not sure what they are tho (any help?)
www.abovetopsecret.com...


Sweeden
Visby class, corvette/patrol boat
Stealth features: angular design, RAM, camouflage paintwork, all other signatures reduced
www.karlskronavarvet.se...

HMS Smyge, Technology demostrator
Stealth features: mostly early versions of the visby class systems
www.canit.se...

Greece
Vosper thornycroft built some stealth patrol vessels for the Greek navy, cant find the info on them yet.


Vosper Thornycroft is getting quite a reputation in the industry for stealth ship designs, including triton, sea wraith, Cerberus, vsv's, a number of patrol boat designs and they helping on the type 45. I have even heard rumors that they have a ship version of the skunk works hidden away in the yard???

Dude think you can give me more websites to visit?

Germany France Spain and Sweden all have stealthish ships in service, under construction and on the drawing board......It is like everything an evolution.

Malaysia has just taken delivery of several German built MEKO A200 Stealth Corvettes. They have three in service, three ordered and may build 21 more for service in amongst the island chains of the region.

Kokkums site, promoting all thier products including the Visbies explains it like this.

Thier Visby has one third the radar cross section (RCS) of any current warship, has state of the art sensors and weapons outfit, and her shape and her paint job render her difficult to see.

Theoretically, up against a non stealthy ship she can close nearer before firing ASMs and is three times more likely to survive an engagement than an opponent.

The RN was trialling a Trimaran hull called the MV Triton. She is about one third to quarter the size of any proposed ship based on her hull form. If her trials were successful (and the USN was involved in these) then she may form the basis of the Type ?? class Frigate (less likely with the UK defence cuts.

An artists concept shows a long warship, with key machinery and systems (such as powerplant and CIC) in the hullspace between the outriggers. She would incorporate stealth and automation, and vent exhausts under the deck between the outriggers thus cutting the IR signature. The wide deck space allow the operation of up two Merlin class ASW helos or a number of rotary UAVs. There is also space for a variety of weapons systems including ASW, Ash, CIWS, Guns.

If built to the artist concepts they would be drop dead georgeous ships with a top speed of 40-50knots and comparable range to todays frigates.

But I dont know if thats still the plan.

Opps sorry.

This is the link to the Kokkums shipyard site. Enjoy

should be able to soon.

I really don't get it at all.

One day, every single nation will have somewhat stealth capabilities for boats, jets, and whatever to a point where there might be a demand to make a device to detect stealth vehicles.

Sounds puzzling to me.

The Burke class has no real right angles for radar to bounce off of, and by angling the mast like that it adds to the stealth. If you look at the railings they are all turned so that the "point" of the square faces outward, so the radar won't have a big flat surface to bounce off of. I've heard stories of Burkes going right through a CBG and nobody knew they were there, until they saw them. Ok, they DO have right angles, but they MINIMIZED them, to as few as possible. Everything that might have a right angle was turned when possible, or redesigned so that it would be a minimal angle.

the arleigh burke class follows similar stealth design philosphies as the Duke class (type 23). IN that they have angled surfaces to reduce radar signatures. They were designed in the 80's, the latest generation takes this even further as can be seen in the design of their replacements

There have been reports of small stealth vessels cruising around Portland, OR. According to the KATU report it has been built for a "private customer", which you could take to mean a civilian. But I don't know why a civilian would need one of those unless he was a pirate. hmmm. What's interesting is that the ship has been developed over the course of a few years. That's quite a long time for something destined for a private buyer. I've read all the articles and posts on this already, so don't bother posting them. I just want an eye witness to tell me if they've seen it in person.

Don't forget about the Swedish Skjold. They certainly seem to be working on this technology.

Greetings.

I would just like to point out that the Skjold class fast attack craft is a Norwegian design and is being built in Mandal , Norway.

We don’t produce much indigenous military hardware, so I would like to blow our own trumpet when we do.

The Norwegian navy has ordered six boats of the Skjold class, these are to be delivered in the time period 2006-2009.

Here is a link to an article (in Norwegian) about the project.
www.mil.no...

The site states that; the Skjold class vessel is the fastest warship in the world with a top speed of around 60 knots.
The ships are custom designed for the Norwegian navy’s operational requirements, they will mostly operate in or in close proximity to the archipelago that dominates our coast-line.

I believe the USN has leased a Skjold from the Norwegians as well, to collect data for use in the LCS program. There is also an Australian fast amphibious stealth catamaran being tested by the USN I believe. I will try to post more detailed information tomorrow, I have pictures of the beast somewhere.

If you mean the HSV-X1, then it is not stealthy at all (at least it is not designed to be). The US Army and Navy jointly leased an unused catamaran car ferry to trial the ship design form for a high speed logistics ship. By all accounts they very much liked the idea.

Yes, that was what I was talking about. Guess you are right taking another look signature reduction does not seem to be a priority. Snarky-looking though:

A patrolboat takes 5-12 minutes to hide with the onboard nets. And that was with the old only visual-only nets that tended to get stuck EVERYWHERE. I swear I saw it snag on a smooth surface..

You hated those nets to? Wow were they amazing...they could hook on SAND. Never understood why we didn't use canvas, plywood, sheetmetal...ANYTHING other than a fishing net with little metal rings in it.

the cats were just an evealuation of the concept of high speed in theatre logistics. As such they needed a small, fast powerful vessel with a major cargo carrying capacity and associated deck space. It was an inspired choice to use the high speed ferry to evaluate it the concepts and see if it was a useful tool (apparently it was). It would not be hard if the Navy decided to commission some vessels to redesign them to incorperate stealth

I apologize. Obviously you are correct. I must have been looking at a site for a Swedish ship at the same time. Thank you for the correction. I wouldn't want to take credit for such a cool ship away from Norway!

The HSV-X1 has been living out here for months now. They've been helping set up a ferry system using it, because they're going to have a smiliar design, and I think they've been doing some testing and exercises with it at the same time. Very cool ship.
