Ben Rich, the director of Lockheed's "Skunk Works", wrote that they had a prototype stealth ship that worked too well. It's radar defeat was so good that it would return a smaller signal than the waves around it. So to the observer, it looked like a void of perfectly smooth water moving through the ocean. He said that it broke rule zero of stealth; 'As quiet as ambient noise, not quieter!'

I've actually had a chance to see for myself how bad of a reflector a wooden sailing ship can be. Last year we were sailing to Finland to participate in the Tall Ship Races. It was a foggy day, and so we had our radar turned on, since barely anything could be seen through the fog. Suddenly, a ship apeared on our port side. It was a wooden schooner, 30 to 40 meters long, passing no further than 100 meters away. Barely any radar signature was visible. Luckily, it passed through us without crossing our course

@CR BZ Submarines have a lot of drawbacks, and you don't always need that much stealth. Sure, a sub can pass very close to almost any vessel undetected, but there's a lot of ocean. If you can spot the enemy and maneuver around them before they spot you, that's all the stealth you need.

@whispofwords2590

5 жыл бұрын

@CR BZ buddy, not to antagonize but theres alot wrong with that statement. For one, they arent meant to be stealthy as in difficult to detect in the first place. Instead they are designed to make it hard for the detection equipment of enemy surface combatants to first find them, percieve them as a threat, and then direct ordnance at them. Two, everything cant be a submarine. Everyone in the online military community seems to have this impression that if one thing does one job well everyone should devote everything towards it. But a submarine is not imposing; its not a deterring threat and its not good for gunboat diplomacy. Submarines also cannot offer consistent artillery support for ground forces, which if I remember correctly is one of the things the Zumwalt is going to excel at once they find a suitable gun. What I'm basically trying to say is that Zumwalts stealth is meant to give it an edge over other surface combatants, particularly other destroyers and in some cases land based missiles by making it harder to detect and hit. Its not meant to make it "sneaky" like a submarine. Besides, weve already got a substantial submarine fleet.

would have been nice if you included any footage of the stealth ships.

if you wanna go more in depth learning about radar, you should check out Radar Absorbent Materials (RAM). Some of RAMs use rought micro surfaces to scatter or attenuate radar in a fairly controlled way.

In regards to texture, the specific paint used may also be partly radar absorbent, resulting n a smaller echo being created at all. And interestingly enough, choice of material actually resulted in a couple early stealth aircraft being created during WW2. Both the Mosquito fighter-bomber and (although it never got past prototype and noone learned for decades) the HO-229 had very low radar cross sections compared to their actual size because of their wooden construction.

You add ballast tanks, nuclear power plant, dive planes, an oxygen generator, double hull in the shape of a tube, and arm it with torpedo tubes and Tomahawk missile tubes, and a periscope.

stealth has several different objectives depends on where you are, and what you want to do in case you do get noticed, and the weapons the enemy possess. for example, some shapes make the ship looks BIGGER, because, the enemy has radar seeking missiles, so, in order to confuse them, you want to look bigger, so when they target you, they'll miss and hit the water.

Nice video, keep up the good work!!

Thanks for the video, you kept it quite short for a similar topic, yet covered all the main aspects in a good way. Only a note: density goes against wave propagation in a medium; it is elastic reaction that increases it. Water is almost unncompressible, while air can be easily compressedby pressure waves; that's why water propagates sounds at much higher speed than air. Iron has a higher elastic module, thus the propagation reaches 5000 m/s through it.

Just found your channel by complete chance today, instant sub. Loving it, very educational and answers a lot of questions I didn't even know I had.

I enjoyed this longer vid and found it well worth watching. Thank you.

You can see a lot of tradeoffs in action. The F-117 follows most of the criteria, yet something like the B-2 ignores several of them, or doesn't go all out with them. Supposedly the F-117 was built on the idea that a diamond shape was the stealthiest, but for obvious reasons, that won't fly, so they modified it from that ideal the least amount possible to get the thing to be able to fly.

@peterc9243

5 жыл бұрын

The F-117 was designed that way because computers at that time were not capable of calculating Radar Cross Sections (RCS) of more complex designs, so they went for flat surfaces. This video is fairly accurate for a "how it works" sorta thing, but in the engineering and physics level it gets lots of things wrong. The way radar interacts really is far more complex than this. If you want I can explain you more in depth how radar actually works and how to achieve Low Observability (LO).

How to make a stealth ship: Tell the U.S. Navy that you’ve a secret design for a stealth ship. Secure money from them to build the ship, and when they ask to see it, show them your ship in the harbour. They will ask, “where is the ship” to which you reply with a subtle nose tap. This will eventually get into the press and enemies of America will literally shit themselves over a boat that they can’t see, resulting in surrender from all hostile nations. You effectively made world peace, and a hefty profit too.
