That's how they hover, Sure, Hawker wanted you to believe they were using vectored thrust, but anyone who's seen one at an airshow knows that they hover on pure noise.
Part of my daily commute involves driving very close to a runway that supports F15's and the occasional Harrier. I once had the misfortune of driving directly underneath one of the Harriers as it was landing, and the sound it gave off had enough violence behind it to shake my truck. Scared the bejesus out of me, despite working around jets for most of my life.
Hawker needed the engine to do just 1 thing: to produce as much thrust as was possible. The Pegasus engine achieved that. It is an absolute MONSTER of an engine but it makes zero compromises for it's thrust.
I went to an airshow where F-35s were on static display. I'll cut the story short but had to stay an extra day due to car issues. Next morning while logged in to work - HOLY FARK. It was the F-35s leaving. They may be stealthy on radar. But certainly not in the audible spectrum!
I work in a building that is very very close to a runway where F-35s take off and land throughout the day, most of the time it's a nice background rumbling but then every couple days they fly low directly over my building
I remember telling my dad that at an air show as a kid and his response was something like this:
It’s loud because it’s like 30cubic yards of air compressed down to a couple inches, then mixed with fuel and ignited so it’s explodes out the ass end of the aircraft.
It would be cool to see exact numbers for some random jet engine just for reference but google really doesn’t seem able to tell me. Apparently the compression ratios of modern engines approach 60:1. Can’t find anything on the combustion chamber and how much it expands.
Also loud are F-15's! I was lucky and was at the end of runway when one was going into a vertical climb. Both engines on full AB pointed straight down almost directly above me: I felt my bones turning into Jell-o. It was awesome.
I saw RAF F-35s flying in formation for King Charles’ birhday. There were also Typhoons, and I gotta say, compared to the typhoons, the F-35s were whisper quiet. Jets are still loud, but sound loudness is relative
Perspective matters too. They fly 35s out of the local base and I hear them all the time. They’re not always crazy loud, sometimes right overhead and not bad at all.
When they’re loud though, they are unbelievable. The sound conducts through your bones to your soul, it’s absolutely incredible how loud the F135 is
I used to live under a flight path for El Toro back in the day. I learned from a young age that the military doesn't design things thinking about how loud they are. In fact, it sure seemed like they might have designed aircraft to be as loud as fucking possible. I've seen a pair of F18s so high up that I could barely make them out. Meanwhile, they sounded like they were 500 feet above my house.
Unrelated, I saw a flight of 4 Sea Stallions flying near my neighborhood about 700 feet in the fucking air. Not as loud as the fighter jets, but still too loud for my liking lol

Can anyone here compare them to the Prowler? I know how those sound/feel having been on the flight deck with them.
jeb_hoge@reddit
I can't say for sure but I think the tonal quality is different.

F35s aren't loud --- Harriers are loud. Harriers are so loud that they rend the fabric of spacetime.

They make so much noise that the earth pushes them away.
jeb_hoge@reddit
I'm pretty sure a Harrier in hover made it rain on a humid day in DC once at an air show I was attending.
Direct_Witness1248@reddit
You're technically correct, as noise is just how we perceive moving air.

Saw a harrier hover at an airshow as a kid. Loudest fucking thing there by a significant margin.

As someone who works 500 feet from a runway with f-35s I feel you.

There's a large steel plant 4 kilometers north of my workplace.
When I heard an F-35 approach once it was so loud I thought it must be flying directly overhead of us.
Then why I saw it fly near the steel plant I noticed it was flying behind it's chimneys.

Almost as loud as they're expensive.

They are only slightly more expensive than the latest and greatest F-16. They’ve really gotten costs down a lot.

VerStannen@reddit
Wonder if the pilot knew the position of the photographer, and did that nice little roll to show off the belly and after burners.
Either way, pretty sweet.

He did, photographers always set up at the end of the runway.
