      Does the radial emulsification retardant get applied to the coaxial pentameter of the hyperencabulator, or is it referentially side-aligned to the interphase induction rotor?

        The hyperencabulator was experiencing sinusoidal deplanarization, so a series of marzelvanes were attached to the Q-sprocket.

    All but irrelevant. Something like 80% of a stealth aircraft's ability to be stealthy is reliant upon its shape.

      Pretty sure shape is just smokescreen. Those Blackhawks that went for Hitler, had something onboard that made them stealth that had to be destroyed asap as soon as one of them crashed. Remember, destroying that thing was more important than rushing in to get the job done. Probably the same thing that fucked with 22 pilots and caused couple of crashes.

        You're a fucking retard. Radar dissipating structures are something that literally any citizen scientist can verify, because it's not like civilian radar is hard to get ahold of and even a minor reduction in RCS from rotating a sheet of metal demonstrates the concept. Those Blackhawks had geometry not meant to be seen, but what was actually being destroyed with extreme prejudice was comms equipment. The jammers on board as well as radios with keys, and data link adjacent stuff are all on the "burn immediately" list. Now remember that they also had spooks and their commo shit onboard as well as a direct stream to the oval office. The order of operations was probably the way it was because when that helicopter crashed the CIA there and at home was probably pissing, shitting, and cumming until someone agreed to clean up the mess before anything else could go wrong.

    Why are stealth bombers always flying wings but you don't see that with other stealth aircraft? Is it because other aircraft have to retain maneuverability?

      It's partially what you said and mostly because only two true stealth bombers exist and one is an evolution of the other.

              It's still invisible to any country outside of NATO. Even most NATO nations either can't detect it at all, or only with difficulty. The U.S. uses F-117s as training vehicles to teach its own armed forces how to detect and react to stealth aircraft entering & operating in a conflict zone. F-117 pilots still have skillz & bags of tricks to fuck with even U.S. systems.

              Hard Mode:
              Name another aircraft that equals or surpasses the F-117.

              the real reason is that the f117 could drop laser guided bombs where b2/f22 could not

              Inferior, but far from useless. You need to understand that the Serbian battery basically made an educated guess when it shot down the F-117, and he was only even able to make that guess because the F-117 had already flown that exact path multiple times and been observed visually, AND he took a massive risk and beamed his location as a SAM well past doctrine when in any real war that would get you three dozen anti radiation missiles stuffed up your ass and he STILL didn’t get a lock. That SAM commander was damn good at his job. A lesser operator could not have downed that F-117 and that was the absolute best case scenario for engaging a stealth aircraft, pretty sure it even still had the bomb bay open and thus had a dramatically larger RCS than usual. It’s a really scary plane that will defeat the vast majority of detection systems and can drop a very decent amount of extremely powerful guided munitions.

          The days of dogfighting is over. Especially when you need to haul ass and get across the pacific to take over the drones who are carrying hundreds of missiles for you. Getting rid of vertical stabilizers lowers drag and observability. It's a win win.

      Stealth fighters still have to function as fighters so there's a compromise between stealth and aerodynamic performance. Stealth bombers can focus entirely on stealth because they only need to get from point A to point B without being seen.

        i dont know is some random bullshit cooked up in a lab. the polymer isnt important. The important part is the doped carbon structures, i also dont know what those are. But they act like retro-reflectors that aim back at the dielectric layer. The hull has to be isolated and electrically charged while it dries or else the carbon reflector/absorbers wont be facing the right direction and it doesnt work.
