It still allowed us to learn a lot and factor the knowledge gained into the production of future ships. Even if they aren't quite as stealthy.

[@termitreter6545]

Yeh, almost all modern war ships have features to limit radar reflection, and a lot of that knowledge comes from that experience. Even with aircraft, "stealth" isnt really about being invisible, but just about making it a bit harder to detect you, track you and engage you. Even the F-35 doesnt need to be invisible, but just 20% increased survivability can be a big deal in war. Similarly "non stealthy" planes like Eurofighter or F-15 EX have a bunch of features to limit radar reflection. Then add modern electronic warfare (jamming, decoys, etc) to make it even harder to combat your plane, and everything adds up. The Zumwalt is a great example for when you try to force stealth so much that the trade-off makes a worse or just not affordable weapon system.

The problem with the Zumwalt Class Destroyer (most expensive Destroyer in the world) is that the West needs Destroyers as the minimal class to launch Tomahawk Cruise Missiles. Russia on the other hand, can fire their equally devastating Kh-101 Kalibr Cruise Missile from Corvettes, which the Russian's claim to have "Stealth Features". I don't know about those claims, but I know a Corvette is harder to spot than a Destroyer. I think the main issue is Cost for the Zumwalt class, same as why we're not going to be building any more Gerald Ford class aircraft carrier's (also most expensive in the world plus maintenance). Despite our US Military budget being higher than the world combined, a big chunk of that actually goes missing, and into projects that get costlier and delayed (such as the US Hypersonic Dark Eagle Project which again just got delayed).

The WW2 Germans used an anti sonar coating on their submarines called “Albrecht”. Tested on 1942 it suffered from poor adhesion but this was fixed in 1944. A u-boat called the “black panther” caused the allies problems but it hit a mine. The Germans also used an anti radar coating called schornsteinfehger on their mast heads. Late 1944 tech so too late to make a difference.

[@Sherwoody]

The German submarine U-480 had the stealth coating. I think it was destroyed by a mine.

[@deepbludreams]

Big doubt, Sonar and Radar are two different things and no evidence exists to prove any of the German WW2 Stealth paint or coatings ever worked, when the HO229 was taken apart and studied (often called a stealth bomber by idiots), no evidence of the so called "stealth coating" existed. Sonar works by bouncing sound off the sea floor or whatever is in the water (subs, ships, fish, whatever) unless this WW2 German wonder project made a U-boat somehow have zero mass to allow sound waves to go though it, it did not work, *real* sonar protected stealth ships are stealthy to sonar by having very little of their hull in the water, sonar returns incorrect data. Radar works by bouncing fast as light energy waves off objects and measuring return samples, "stealth" aircraft avoid this by deflection or energy absorption and not allowing a return sample to the radar, this does not work on sonar.

[@williamzk9083]

​@@deepbludreams The German Anti Radar Coatings and Anti Sonar Coatings were extensively investigated after WW2. I will link to the reports but if you google . " The Schornsteinfeger Project C.I.O.S Report XXVI-24 May 1945. " We have many reports and were found to work very. Don't call anyone an idiot because often the bit of an idiot may turn out to be you. The anti Radar Coating was a German Navy Project arising from Doesnitz's 1943 anti radar conference and had nothing to do with the Luftwaffe. Never trust Natgeo, Discovery or the History Channel even if Northrop Grumann is involved. -Schornsteinfeger was a Jaumann absorber used on snorkels with hundreds of subs subs were equipped. It absorbed 96% of radar and reduced detection range to only 15% for 9cm radar in calm seas. Worked also with 3cm radar and was more effective in rough seas due to the reduced signal to noise ratio It had 9 layers of cardboard impregnated with graphite to make it semiconducting. This was impregnated with plastic to make it water proof. The density of the graphite increased exponentially to absorb the radar. For a metal surface Think of a wave hitting a vertical harbor wall and a wave reflecting perfectly. The Jaumann absorber is like a gently slopped beach, the wave does not reflect immediately but is absorbed in pebbles and rocks as it surges up the slope. What little reflects cancels with the incoming wave. -The other absorber was the Wesh Absorber also used on u-boats. -This worked using ferrite (iron oxide) materials with crystal structures tailored to different wavelengths. Wheras the Jaumann absorber absorbed 96% at its optimal wavelength the 80% at 1/3d wavelength 3 wavelengths the Wesh worked at 90% but spread over about 10 times the range. -Wesh was only 2mm to 4mm thick and made of corrugated rubber. It was used on the curved pats of the snorkel and periscope where the jaumann absorber was harder to fit. -The two methods Jaumann absorber and Ferrite could be combined to achieve 99% absorption across a wide band. This was not used in service due to the end of the war. -Proof the Germans had effective radar absorbers.

[@williamzk9083]

@@deepbludreams - I have posted above on German anti radar coatings used on their submarine snorkels and periscopes. I have given declassified Government sources. -Now I will post on the Albrecht anti sonar coating applied to u-boat hulls. -Albrecht consisted of metal mesh punched out with two or more sizes of holes. The holes were filled with rubber and the mesh covered in thin rubber. -The hole diameter determine a resonant frequency. Absorption of sonar and sound waves was at its p0eak at these resonant frequencies but also worked to either side creating a broad band absorber. -Albrecht seemed to reduce detection range against passive hydrophone sonar by about 15% which implies about 70% absorption of sound (power of 4 law) . It's effects against active sonar were to similar degree. In general a 50% absorption achieved only a 15% reduction in range (power of 4 law) but its usually 2-3 times more due to S/N ratio reduction.

[@rex8255]

It's worth (IMHO) mentioning that part of the reason for no curved surfaces is that they just didn't have the computing power at the time to calculate a stealthy hull or fuselage with curves. Hence the reason modern stealthy aircraft DO have curves is that this isn't a problem now.

When problems with the guided munitions arose, it simply made all the other problems the ships were experiencing unbearable. With each round costing almost 1 million, well...

Subs don't have "stealth" an undetectable sub does not exist, nor a "stealthy" one, good reason why subs spent the entire cold war tracking each other. Subs only have "Stealth" with in X distance of destroyers, it's why modern sonar systems are such a heavily protected state secret. They are just hard to surface detect because modern ones can just stay underwater for their whole patrol, surface ships can and do detect subs with hydroacoustic systems of various flavors, and after a torpedo or missile launch they pretty much instantly die from return fire in the form of surface ship launched torpedoes or helicopter anti-sub torpedoes/depth charges Also on the surface or at launch depth they are pretty easily detected, the destroyer is still the natural hunter of subs, subs have not displaced surface ships, hell even an entire class of aircraft exist to kill subs, not to mention aircraft dropped submarine detection systems. So no, Subs are not protected against air strikes, if anything they are the least protected, they cannot really defend themselves and any hit will in most cases sink a sub.

The one in the movie is shown to be much bigger though. I wonder if they were able to use the real ship or used a miniature. The timing looks right as well since it was just declassified when Tomorrow Never Dies came out and the ship wasn't destroyed yet.

[@jonm2438]

the Villain in the James bond film “Die another Day” used that ship as his flagship. It was neat

[@charlesolinger9735]

Easy answer is. The sun comes up every day. Stealth goes away. Kinda lame.

[@sandsandwich9217]

​​@@mirthenarysimple, stealth aircraft have the speed advantage and could outrun and outmanuever missiles and other aircraft, while a stealth ship has the disadvantage of not being able to hide in the clouds like a jet fighter does, also Stealth Submarines have the advantage of outmanuevering and counter enemy fire by diving or deploying dummy submersible's to confuse enemy torpedoes. Generally Stealth Ships have the disadvantage of not being able to hide their radar cross section efficiently and not being able to outrun their enemies without depleting their weapons and other assets, once that ship is spotted enemy aircraft will be sent for support and destroy it, all in all stealth technology is only highly feasable on submersibles and aircraft.

[@konstantinavalentina3850]

I think the model is wrong. There was a boat called "Ghost" built by Inventor Gregory Sancoff who wanted to make a cool boat for the Navy had propellers in the front of the torpedo-looking pods. The propeller in the front design created a supercavitation effect allowing the boat to go much faster. The Sea shadow takes many design elements from Gregory Sancoff's design. Whether or not Sancoff got anything out of the Navy "borrowing" from his concept is probably locked away behind security clearances and NDAs.

[@timeshark8727]

Frankly, stealth ships are redundant. Being able to find, and more importantly hit, a ship in the open ocean with long range guns or missiles is already incredibly difficult. When attacking fleets with planes you are often within visual range, which there is no stealth for. Then there are submarines, which are an entire class of stealth ships.

[@Demonslayer20111]

You can see a ship of any decent size at hundreds of miles with radar, basically to the horizon, which can be extended with aircraft. If you can't see it on radar you would need to visually acquire it, which fair weather is about 30 miles or so. Not to mention the fact that stealthly ships DO exist. There are many full stealth, and reduced radar cross section ships, the new Gerald R Ford carriers being one, as well as the San Antonio class amphibious dock ships.

[@mirandela777]

"When attacking fleets with planes you are often within visual range" 🤣Yeah, sure, is not like we have radars, and airborne radar, who can "see" ships at hundreds of KMs, or sonars, who can "hear" ships at THOUSANDS of KMs ! Or satellites / drones, who can see a ship trails from space !

[@Wannes_]

Just about all newly constructed warships have some degree of stealth measures, like angling the sides, hiding anchors ,lifeboats, fittings, behind screens or inside the superstructure, cutting off corners, weird shaped stanchions, less black paint, ...

[@mirandela777]

@@Wannes_ - true, but only an idiot ( or mafia and corrupted DoD, like the US ) will invest zillions ( zillions like in Zumwalt, the murican failed withe elephant ! ) only an idiot will invest millions in a full stealth ship - is just impossible to "hide" a big surface ship. Is NOT just the Radar - is the visual acquisition from Space, the IR signature, and, crucial, the NOISE. You simply CANNOT move FAST ( over 20 knots) and remain silent. Especially on the surface. Modern satellites can spot the trails of medium/big ships from thousands of KM, then extrapolate instantly the position of the ship. Any decent navy who want stealth ships will build subs. Corrupted idiots will build Zumwalt.

The original Sea Shadow was likely retired either scrapped or is being held in storage somewhere. However, see that the idea of a stealth surface ship is bonkers in my mind is being too shortsighted. Now a lot of people seem to get terms, mixed up or mixed together. For instance, I’ve seen people basically use the phrase stealth to equate to essentially invisibility. Now stealth doesn’t necessarily mean being visually unidentifiable or detectable. Current stealth technology is all about being invisible to sensors. After all, even on a flat featureless ocean , without advanced optics and stuff even trained naval personnel likely will not actually see a ship coming until it is at the point of which we would call on the horizon. And by the way, the average human can only see about I think it’s 10 miles before their brain essentially can’t discern what something is in the distance without enhanced optics. The sea shadow itself I like to think it was more of a proof of concept. Rather than an outright idea for a ship. Now the kind of technology that it used to float, and all that stuff is a well understood technology. In fact, there are private companies that are developing Both pleasurecraft, and even potential rescue vehicles that have a similar design in terms of how they go through their locomotion. One of which is very interesting, where the screws actually aren’t on the rear of the vessel they’re actually at the front. And they act like the propellers on an airplane, pulling the vessel through the water instead of pushing. But again, I’m more than willing to bet that the technology that was used for the development of the sea. Shadow is probably still highly classified and newer versions are likely on the drawing board, if not in small scale, prototyping tests. Vessels like this would be ideal for the deployment of special forces units, or even to be used as scouting vessels. Hell, another idea would be use the overall design, but shrink it and turn it into an un spy device or something. Honestly, the overall idea of a vessel like the sea shadow at least I personally feel is scientifically and tactically sound. Think about it this way. The Comanche. The space age looking stealth helicopter that would’ve probably supported and then maybe it some point replaced the attack helicopters such as the Apache and cobra. Allegedly that program was also shelved, but we also need to take any consideration. The fact of the alleged stealth Blackhawk helicopters that were used during operation Neptune spear. Something tells me that the stealth attack chopper idea didn’t pan out at least as much as we know they likely use the data for the development of these stealth versions of the Blackhawks. They say that the project has been canceled likely does not mean that the project truly has been canceled. It may simply be stated that way to pull it out of the public eye. Perhaps something was discovered that required more in-depth and secretive testing.

[@1slotmech]

Sea Shadow was scrapped. Its hangar, after sitting in the Suisun Bay mothball fleet for a number of years, was sold to a ship repair company for use as a floating dry dock; Bay Ship & Yacht Co, Alameda CA USA.

@@YellowLab-bg3os true that satellites have time windows, but those time windows are very short. But even if you managed to stealth the entire support fleet, the enemy are bound to notice something. Also the sub carrier worked, but it probably couldnt carry enough fighters, ammo, or jet fuel to be effective

[@petermgruhn]

If that were true, then there'd be no other warships. There are other warships. They aren't very stealth. Wouldn't it be nice if they were? Let's build a testbed to see what we can learn. To apply to the non-submarine navy that we already have and expect to continue to have.

[@bluestingray8955]

@@petermgruhn the modern surface fleet is not designed with stealth as the main priority, their roles are completely different. The reason people don’t make stealth ships is that there is no obvious advantages to them over submarines which are inherently better at being inconspicuous. I can’t name one thing a stealth surface ship can do that a submarine can’t do. Wanna sneak up on an enemy ship and sink it with torpedoes? Use a submarine. Wanna conduct reconnaissance on enemy naval activities? Use a submarine. Want to deliver special forces soldiers inconspicuously to an enemy shoreline? Use a submarine. In conclusion stealth ships aren’t a thing because which have submarines which are objectively better

I had a toy Sea Shadow as a kid and the top part near the stowage bay could open and reveal four missiles.

[@Sagart999]

Sea Shadow was being designed while I was assigned as a junior officer to the NAVSEA Preliminary Design Branch. Sea Shadow was one of those programs with a huge "need to know" sticker on it, and the powers that be decided I didn't have that particular need. So, independent of that team's work, I actually designed my own stealth corvette. I had done my post-graduate work on SWATH hullforms (like Sea Shadow), but I based my stealth design on using a single large lower hull on the centerline and a pair of sloped "outrigger" waterplane areas like you see in this video. There are certain minimum dimensions associated with propulsion machinery components, so by packaging them in a single slightly larger diameter centerbody, I was able to make the overall vessel smaller than it would have been otherwise. What comes around goes around and fifteen years later I became part of the DDG 1000 design team.
