> It really is hard to figure out where to do a thing and it's also very easy to get phished

Maybe the federal government could use some of its powers to prevent literal phishing and scam sites from showing up in the advertising for the first, top listed results from search engines when non-technical boomers (or technical knowledge equivalent of) search for certain basic services. It seems there's very little actual evaluation by the ad-serving-entities of whether the destination of an ad is a legitimate thing these days.


Until very recent price changes, at the scale that they purchase hard drives, I don't think that there would have been significant cost savings in purchasing SMR drives. Particularly after taking into account the additional hours of software development required to write custom host managed SMR stuff to deal with the performance problems.

The F117 is in active use as a stand-in/simulator for opposing force semi-stealthy subsonic cruise missiles for radar range testing. People see them flying all the time.

This is essentially the thought process behind the Hermeus Quarterhorse which is already a thing that exists and is in active development:

Don't forget the new 'Battleship'. You should have seen the looks on the faces of some of the DoD people when they trotted out the big CGI rendered posterboard of the thing. They know it's a boondoggle and they're kicking the can down the road.

> or processes can be restarted if they were not preserved and actively practiced.

One of the reasons why the UK went vastly over budget and behind schedule when they built the first Astute class submarine, because almost everyone who had domestic UK based hands on experience building a nuclear sub had long since retired. There's certain technical things, both military or non military, where if you stop making them for a long period of time (at even a minimal rate of production), the institutional capacity to implement them dissolves away.


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?

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.


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. https://hforsten.com/interferometric-synthetic-aperture-rada...

It looks like a DIY implementation of some of the commercial land surveying SAR payloads that companies will sell you (for $60,000) to fly below a DJI M400 or similar size craft for tasks like monitoring open pit mines, etc. Also not realtime data return over RF data link, it's a download and post-process workflow.

I think you are confused. Spy satellites do not use geostationary orbits.

It's not something I can cite with any public URL to a website that's an authoritative source, but if by 'spy' you include SIGINT satellites in that category, yes they absolutely do... Ever seen a diagram of a Boeing (Hughes) 702 series satellite bus and antenna system built for L/S-bands like frequency ranges similar to those used by Thuraya, Inmarsat and Iridium handhelds?

It's widely accepted in the commercial two way satellite telecom industry that the NSA has comparable things with big unfolding umbrella-like antennas in geostationary which serve a similar purpose for signals collection.


Why do you think I am confused? Is this a form of internet condenscension, or are you able to diagnose my mental state based a single comment? No, I don't think I'm confused.

Well there's also the X-37B Orbital "Test Vehicle" that performs some long-run missions. Satellite warfare? Observation instrument tests? Who knows!

Didn’t satellites with superior optics and realtime video streaming … kill the need for an SR71 update?

For visual and SAR, sure, but there are other missions like electronic warfare and signals intelligence that are still well served by aircraft.

Not by a mach 3+ aircraft. Good luck getting signals through the plasma of your own wake!

Plasma is electrically conductive. Modulate it as needed, in realtime.

Enjoy the dynamically phased plasmarray.


> I'd be more astonished if there isn't something superior to the SR71

Makes me wonder if this whole operation is just public cover for something like that.


The problem is the people in charge now have not earned that kind of faith. If they’re truly trying to relight these things, my heart goes out in advance to the neighborhood in the Southwest that burns down before they rethink it.

> The problem is the people in charge now have not earned that kind of faith.

If you set partisan politics aside for 90 seconds, you might realize that regardless of the administration publicly in charge, the government is always doing stuff behind closed doors that your brain could not even begin to comprehend how they pull it off.

Stories like this hilariously implausible "grizzled old man casually leaks secret program to Aviation Week" is like throwing a cat a ball of yarn.


Now turn your brain back on and wonder a 34-time felon & rapist POTUS who steals from charity is doing behind closed doors.

On the other hand our commander-in-chief (engineering expert that he is) has ordered the Navy to switch back to steam catapults on an already half-built carrier. That will also require bringing back 70 year old retirees. Pretty sure Trump would switch back to coal if he could find any living boilermakers.

Sometimes bad ideas are just stupidity.


Political scientists are well acquainted with madman theory, but have we defined "dementia theory" yet?

https://en.wikipedia.org/wiki/Madman_theory

Irrational and volatile as a play-act is one thing, actually being irrational and volatile is a whole other ball game...


This is Isaacman we're talking about. He is about as good faith as they get (low bar, I know, but for real this time).

Or something as mundane as cleaning up and fixing something that's been out in the weather for 20 years so it doesn't look shabby at the front gate of their base.

I don’t know anything but I can’t imagine they need specialists if it’s just a cosmetics job for a monument.

Or the whole "retired guy in his late 70s gives a quotation to aviation week" is a red herring intended for US adversaries, which seems like a fairly basic ruse, but might have been put together as a coordinated plan. It could have its own value of sending opposing nation state intelligence agencies and air defense people down a man-hour wasting dead end of investigating something that'll never happen.

If they were doing that they would say so. In fact if they were smart they would say that regardless of the true story. The fact they aren't saying that means they're either stupid or playing 4D chess. I know which I'd bet on.

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. Never underestimate how often the US military will send a group of subordinate people to do what is effectively busy-work.

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?).


This has got to be a trump thing. "Big beautiful ramjets!" And so on

Yeah it seems most likely it's because someone connected to the administration just thinks they're cool.

Trying to find reason behind so much of this shit is a fools errand. Vibes based presidency.


I know it's probably a forbidden topic around these parts, but the 'tic tac' thing that those FA18 pilots saw several years ago may be indicative of what Lockheed etc are flying up there. It's a hot topic in conspiracy circles but it wouldn't surprise me if a bulk load of ufo sightings were black projects being tested.

>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.


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.


The Tacit Blue is kinda tic-tac shaped (with wings sticking out the sides), but it's also a historical museum artifact now and, as far as I know, was quite slow and cumbersome.

Why look at things with your own two eyes when you can have an LLM drive playwright and headless chromium to QC your website aesthetics? I'm sure nothing will be missed. Don't worry!

It also seems to strongly disagree with RFK's public stance of the safety and efficacy of the full series of standard childhood vaccines.

Cough we're still waiting for those alignment dollars to really kick-in!!1
