The Pentagon Is Using the SR-71's Legendary Engine for ... Something
Pratt & Whitney started working on the Metacomet two years ago, according to Aviation Week & Space Technology. The company’s Gatorworks division is dusting off its work on the J58, which allowed the SR-71 to reach a record-breaking Mach 3.2, with the hopes of using it to help create a new engine capable of propelling a new vehicle even faster.

I used to really enjoy Popular Mechanics. More recently, though, it seems to be nothing more than low information clickbait.
Like many magazines that were a great read monthly, it is now run by a crew of New York metro's who don't own a house or car, slurp latte's with a pinky extended, and look down their nose at the "carbon footprint" of anyone who dares to fly anywhere. It is a shame. I have not found any properly curated source of similar information online.
Hagerty drivers club newsletter is good for some old, muscle car, any kind of old car reading and it's free.
I used to wait patiently for Pop Mechanics and Pop Science to hit the shelves. Now I could care less. My interest in science and engineering’s hasn’t become less just those magazines are not what they used to be.
I think we should re-activate the SR-71 just to annoy China, USSR and Iran.
I invite the author(s) of this article to read the SR-71 Pilot's Manual or Wikipedia. Everything they wrote about the J58 operating in an SR-71 is wrong. No turbojet engine can operate on supersonic airflow. Every supersonic aircraft has a conversion inlet that translates supersonic airflow to subsonic airflow before it enters the compressor section of the engine.
