for anyone who wants to know, that jet is the SR-71. The first stealth jet....that we're allowed to know about...the fastest jet that got real use...as far as we're allowed to know. I heard about the SR-72 on a youtube video.
the SR-72 is going to be WAY faster, over 1 mile per second and the missile it's going to be able to launch doesn't have any explosives, it hits so fast and so hard that it doesn't need explosives to blow things up
Mach 4.6 is about 1 mile per second and they said on that video that the top speed of the SR-72 is going to bbe around mach 5. which means the missile it launches is going to accelerate from starting at that speed
I hope to God we never have to use it, but with mutually assured destruction and all that we need to have it as a deterrent...which is probably why we're allowed to even know about it right now
It had radar absorbing paint which helped reduce the radar cross section, but it wasn’t stealth.
It flew near the edge of the atmosphere and was so fast that when it was finally picked up at that range by the less advanced radars of the time it would already have been out of the range of missiles. Things had cameras on board that were apparently capable of getting a good shot of a license plate from damn near the edge of space (in the 70's!). I have read there were plans for a bomber version but apparently that didn't come to be. It's a shame none are still flying. NASA had a few they obtained and used for upper atmospheric research after the airforce and CIA were done with them, but flying and maintaining them is crazy specialized and expensive. The older U2 spyplanes were made for similar altitudes and found to be a much cheaper and more practical option for that purpose so the SR-71's were retired.
I get that, but flying fast and high to avoid missiles is not stealth. I’m not saying it’s not the coolest airplane to ever exist… it’s just not stealth.
