| Yeah it's certainly unimaginable that the civilization that invented gunpowder, cannons, guns, rockets a thousand years ago can make it for cheap now :) 'Hypersonic' missile makes it sound like it's alien technology, no it's solid boosters that do not follow the usual ballistic trajectory with a computer from 1970. The raw materials cost less than half of a standard car. |

| I've only read a few short blurbs about this. What makes you think the booster doesn't follow a normal ballistic trajectory? |
| |
| ▲ | sgc 21 hours ago | parent [-] | | That's pretty much the entire point of what people are calling hypersonic missiles. All ballistic missiles fly at hypersonic speeds. The advance is being able to do so at low altitude with maneuverability. | | |
| ▲ | larkost 20 hours ago | parent | next [-] | | You are correct, but I should point out that Russia has described its Kinzhal missiles as hypersonic, when they are really more of a traditional ballistic missile fired horizontally. So very fast (Mach 10), but not as maneuverable as what the U.S. has been calling hypersonic. Since the original story here does not provide many details, we can't know which side of that fence this falls on (assuming it is real). | | |
| ▲ | justin66 4 hours ago | parent | next [-] | | Was there any evidence that the Kinzhals fired, for example, toward Kyiv during the current conflict were fired on a depressed trajectory? I remember reading one account that looked like a plain old interception of a ballistic missile. (which is impressive enough to someone who remembers when "Patriot missile" was not exactly synonymous with excellence) | |
| ▲ | fooker 20 hours ago | parent | prev [-] | | Kinzhals being intercepted all the time could also be propaganda or missile defense having progressed more than publicly known. It's not a great idea in war to assume your enemy is incompetent (even when they are). |

Most missiles endowed with the "hypersonic" moniker are simply theater ballistic missiles used for standard ballistic missile things, which is part of why I asked the question. > The advance is being able to do so at low altitude with maneuverability. Hate to burst your bubble but arms dealers and governments are as capable as anyone else of marketing spin. |

| "no it's solid boosters that do not follow the usual ballistic trajectory" Hypersonics do not. They are extremely fast and extremely low flying. |
| |
| ▲ | fooker 20 hours ago | parent [-] | | No, hypersonic is a marketing term here that indicates 'difficult to intercept'. It does not imply anything about speed, just automatic or controlled maneuvering later in the stage than normal missiles do. | | |
| ▲ | esseph 19 hours ago | parent [-] | | The very definition of hypersonic requires at least Mach 5 in terms of speed. sigh | | |
| ▲ | fooker 18 hours ago | parent [-] | | We have had mach 5 missiles for about 60-80 years now, that's not what the novelty is. | | |
| ▲ | esseph 16 hours ago | parent [-] | | Mach 5, high maneuverability, inside the atmosphere. Normally a non-ballistic trajectory. That's been the goal for a very long time. https://www.armyupress.army.mil/Journals/NCO-Journal/Archive... https://en.wikipedia.org/wiki/Hypersonic_weapon Do you have something to add to this discussion? We just redoing definitions, or what? | | |
| ▲ | fooker 14 hours ago | parent [-] | | > Mach 5, high maneuverability, inside the atmosphere. Out of these, Mach 5 and inside the atmosphere have been doable for several decades. Pretty much all countries that make missiles can make missiles with these two characteristics. My point, which you seem to either misunderstand or deliberately misrepresent, is the other one - "maneuverability" - being the distinguishing factor for what we call hypersonic missiles. That makes these difficult to defend against. Think of it like calling humans hyper-limbed animals, but limbs being not what really distinguishes humans from, say, chimpanzees. | | |
| ▲ | esseph 4 hours ago | parent [-] | | Maneuverability isn't new either, aim-9x's can pull 60Gs. MUTANT missiles will take that a step further as the tech works through the Program Office trials. I'm not sure what point it is you're trying to make here, this whole thread seems like a silly waste of time. There are people on this site that work directly in the offices of these programs. | | |

Yeah, step one before replying to something should be trying to understand the point. > There are people on this site that work directly in the offices of these programs. Maybe even in this thread! | | |
