I'd be more astonished if there isn't something superior to the SR71 (likely unmanned) that has been flying around at night from facilities like Groom Lake for years. Look at how long the RQ180 was flying around in semi-public and known about before it became seen in daylight by plane spotters in Greece. And a long time before that there were public relations approved photos of the Lockheed Martin Polecat.
There were a series of extremely public quotations from senior DoD officially recently about how they plan to aggressively retire the Global Hawk program (which is a mostly non stealth aircraft), reading between the lines it's because they have something much better.
I suspect everything comparable of late has been orbital, which begs the question what is it they’re worried about with orbital? Satellite warfare is already accelerating if the rumors are true, is it that this is untouchable still? Is there some new camera sensor where eliminating that extra atmospheric diffraction or slowing down (lol) is needed?
walrus01 3 hours ago [-]
I am sure that the orbital capabilities are also vastly improved from what the public has ever seen. But I think there's likely a high degree of tactical value in having something that can keep station over a certain active conflict area (as an RQ180 can, maybe flying in a racetrack pattern at altitude, with sensors aimed down).
If you've ever seen the publicly released videos and audio of an RQ9 operator in communication with ground units watching the activity of a group of men/vehicles on the ground, in live real time, something like that.
As compared to periodic revisits by LEO orbit satellites that don't maintain persistent live coverage, or the extreme distance and data acquisition problem that aiming sensors in geostationary orbit at a 10x10km target area might pose.
Demiurge 2 hours ago [-]
There are satellites in geostationary orbit that have realtime live feed and agile pointing capability. However, besides the SAR, RGB style observations are limited by clouds, and also you can’t switch out the sensors on a whim. Airborne platforms are always more flexible and cheaper for certain missions.

Without leaking anything that's even remotely close to classified, WAMI (wide area multispectral imagery) sensor systems that can mount on even relatively medium sized group 3 UAV are really damn good these days. This is a pretty basic unit compared to the things that aren't publicly known:
This guy has been working on their own SAR drone for a while, just had another really nice blog post. Definitely looks like it weighs <10 lbs. He post-processes, but I doubt that's that hard to rework.

Another theory is that some smart people already know better, and they know they're going to waste many millions of dollars investigating its feasibility, but they've been given an order from Whiskey Pete and have to at least go through the motions of writing a study/detailed report on why it's not possible to reactivate in a reasonable amount of time or budget.

The SR-71 is because they need to test for speed.
That serves a huge number of things both offense and defense: engagement, radar, missiles, trying to boost the speed capabilities of new planes & weapons. And it applies both to manned and unmanned planes.
Russia is less of a concern now, however China is coming on very fast in terms of leveling up their military capabilities. I'd be very surprised if the US military isn't looking to push its capabilities around increasing speed generally, just as it does any other aspect. There hasn't been a significant leveling up in US Air Force speed capabilities in many decades (since the F22 supercruise three decades ago?).

krapp 16 minutes ago [-]
>but it wouldn't surprise me if a bulk load of ufo sightings were black projects being tested.
Sure, I'd bet a lot of "black triangle" sightings are exactly that. But if the "tic-tac" lore is to be taken at face value, the implication is that the US military has invented antigravity technology, or reverse engineered it from alien spacecraft. I really don't think that's plausible. If the US had that kind of technology we would be so far ahead of the rest of known science that there would be no value in keeping it secret.
bigyabai 2 hours ago [-]
If those tic-tac videos were actually a classified aircraft, those airmen would have signed an NDA before they left the carrier. The fact that we know about it (and see the FLIR videos, regularly, released by the government) suggests that they are exactly what they claim to be; UFOs. It could be phenomena, it could be noumenon.
We've seen a lot of the stuff that used to be classified from Skunk Works, none of them are supersonic orb prototypes or flying tic-tacs. I'm not saying they can't develop that technology and hide it from the public, but it's unclear how all of the puzzle pieces we have fit together to support "Lockheed sends flying orb to Syria without telling CENTCOM" in any way.

To give you an idea how ridiculous this is: to start each engine, they made a cart out of two Buick V8 engines tied together - so four V8 engines to start the plane. Those V8 engines were long since out of production, so at one point they went around the country, to every junkyard, buying up every one of those V8s they could find, so they would have spares to start planes up in different places. If an SR71 had an issue and landed at an unusual airport, they had to fly the start cart and other equipment to that airport to start the plane again. Everything about this plane is expensive and one-of-a-kind. It's a hot rod that goes to space.

Rather than re-engineer the cart to use a different block?

There was something special about the 60s in the US. Your comment implies you might not appreciate how absurd the SR-71 was. The F-35 is our latest fighter jet. It has a top speed of 1200 mph, the SR-71 had a top speed of 2200 mph. The F-35 is capable of operating at around 50,000 ft, the SR-71 was capable of operating at 85,000 ft. The F-35 has a self fueled range of about 1350 miles, the SR-71 had a self fueled range of 2,900 miles.
Look up aviation records and you'll find the SR-71. It even still holds the #1 spot for the fastest airflight (by a plane) ever. Basically, the SR-71 is old, but old doesn't mean antiquated. The 60s was the era that we went from knowing basically nothing about space, to putting a man on the Moon in 7 years (Kennedy gave his 'to the Moon' speech in 1962, first landing 1969), while we currently flail about trying to recreate it with a program lasting into the decades already.
