U.S. fighter jet shot down in Iran, search underway for crew

wesselbindt•1h ago
The article says this is the first jet that was shot down by enemy fire this war, but this confuses me. Was the F35 that was downed a while back friendly fire or something? Are F35s not fighter jets?
hypeatei•1h ago
That one was damaged and managed to land safely, iirc. Depends on your definition of "shot down" I guess, but the pilot didn't eject, so...
malfist•1h ago
We have always been at war with Eastasia
ge96•1h ago
I thought the IR video of that showed it made the missile detonate before the missile hit, maybe shrapnel hit the jet

Then again idk the jet exhaust becomes more significant not sure if afterburner or damage

https://www.reddit.com/r/CombatFootage/comments/1ry6ma2/f35_...

jeffbee•1h ago
That's how anti-aircraft missiles always work.
ge96•1h ago
In that video it seems like something shoots at the missile is what I'm saying from the F35

Someone said maybe a form of DIRCM

eqvinox•51m ago
You're talking about a single "dash" on the frame before it goes all white. First question, if it were a laser, would be what exactly are you seeing there? A laser from the side is invisible, there'd need to be dust there, or the air would need to have turned into plasma. I don't think either makes that much sense. Second question/problem would be… it would have failed/be malfunctioning because —

— pretty much all AA munition works by exploding in close proximity to the target and showering it in shrapnel. So this might even have "helped" the missle/shell against malfunction in its fuse. And considering that this is designed to work like that, and it's likely not the greatest quality work on the Iranian side, it's also possible that the thing is already exploding and just ejected some piece of intentional shrapnel (or unintentionally itself) early, ahead of the actual detonation.

Or the Iranians edited that "dash" into that one frame, it's not exactly like it's a reputable source and it's in their interest to confuse things. Maybe they want the US to believe that the countermeasures are malfunctioning and helping their attacks, so they turn it off…

ge96•48m ago
Yeah I was also thinking the the dash might be the missile itself

The single exhaust plume does become multiple on the F35 suggesting damage

MarkMarine•1h ago
The F35 was able to make an emergency landing in a gulf country. This one actually went down in Iran.

Large, sophisticated, expensive war assets like fighters and carriers are brilliant against literally cavemen like we've been going around fighting lately, but are quite useless against enemies with even slight technological progress. If this conflict continues we're going to see a lot of US assets in fragments.
hypeatei•1h ago
> If this conflict continues we're going to see a lot of US assets in fragments.

Yep, Iran recently destroyed a high tech radar plane ("AWACS") at a base in Saudi Arabia: https://www.nbcnews.com/world/iran/iran-war-attack-us-base-s...

jeffbee•1h ago
It's only "high tech" to the aforementioned cavemen. To everyone else it's a 707 you can't even get spare tires for any more, equipped with some truly obsolete technology aboard. I mean it has a mechanical waveguide for crying out loud.
paganel•59m ago
> equipped with some truly obsolete technology aboard.

So I guess the US won't have any issues replacing it at a cheaper cost (as far as I understood that one cost $500 million, give or take).

jeffbee•55m ago
The prototype E-7 cost $2 billion. It's a 737 with some radios.
eqvinox•40m ago
"On 22 March 2019, the UK Defence Secretary announced a $1.98 billion contract to purchase five Boeing E-7 Wedgetails"

Prototype price isn't really that meaningful

(Also it's a 767 not a 737, that was the E-3 I think.)

jeffbee•26m ago
You must be thinking of a different boondoggle, the E-767, which is the obsolete radar package from the E-3 bolted to a 767. The E-7 is a 737.
eqvinox•24m ago
Ah right, it's a bit confusing between the bunch of these.

Nonetheless the price tag was only $400M/ea E-7 for the UK in 2019 (usual later price shenanigans not included)

ModernMech•1h ago
It reminds me of a Age of Empires campaign I played at a LAN from a long while back, where the game went on for 20 hours and ended in a stalemate between an atomic age player and a very primitive age player. The atomic player had total control of the map, they were carpet bombing the entire thing with nuclear weapons. But they could only create them so fast while the primitive player was running around on horses, just surviving enough to prevent the other player from winning. The only reason the game ended was because I tripped over the power cord to one of the computers.

To me, that's what modern warfare looks like.

Telemakhos•59m ago
When the first-tier hostile leadership structure was eliminated in the first day of the war, and only after a month do the surviving enemies finally manage to damage a plane so severely that it can't return to a friendly base to land, is "quite useless" an adequate and accurate description of the technology used to prosecute that war?
tokai•58m ago
A month after the president claims total air superiority over Iran and complete destruction of their anti air capabilities.
eqvinox•46m ago
Whether you have specific leadership or not doesn't matter much to (a) having to adapt to the enemy and learn what works, and (b) probability just doing its thing, more chances and so on, and (c) US leadership descending the oceans of stupidity all the way to the Mariana trench.
rbanffy•52s ago
> US leadership descending the oceans of stupidity all the way to the Mariana trench.

And they voted for this not only once, but twice.

br121•32m ago
It's useful in saving the pilot's life. With less advanced tecnologies, more pilots would have been shoot down. It's useful in targeted attacks, but they have proved themself uneffective (at least for now) as the new leadership is alined with the objective of the replaced one. It's close to useless when it comes to making the war cost-effective, which start being a relevant metric when the conflict start lasting too long. Of course the US has a bigger economy, so all the news about cheaper systems damaging or destroying quite expensive ones may still lead to a US victory, but a costly one for sure
rbanffy•1m ago
As the Soviet Union made us learn, you don’t need a big military victory to make your enemy spend themselves into defeat.
rbanffy•3m ago
When you decapitate a well organised military, all you achieve is installing a new enemy you know little about you can’t predict their actions and that now know they are fighting for their own survival.

Not the best place to be.

Americans seem to underestimate everyone else.

unholyguy001•56m ago
It’s mind boggling how wrong that statement manages to be in only two sentences. It’s like every word manages to be wrong multiple times

davidcollantes•36m ago

MarkMarine•1h ago
Military aviators train for this, being alone behind enemy lines (look up SERE school if you’re curious, one of the craziest training courses outside of special forces) and there is a special force just for aviator recovery behind enemy lines, US AirForce Pararescue. Hopefully they’ll get the aviators back quickly, the last thing our country needs is American hostages making this ridiculous war harder to stop.
tokai•1h ago
Prisoner of war, not hostage.

edit: I'm baffled by the amount of downvotes pointing out the objectively correct terminology can get. Its not a matter of opinion, military personnel captured by the enemy are pow no matter their treatment. A hostage, by definition, has been abducted.

spwa4•58m ago
That is assuming Iran holds itself to the Geneva conventions, which ... seems like an extremely risky bet to make.
Tadpole9181•57m ago
Especially after the double-tap on civilians and first responders the US just did on that bridge. Or the threat for no quarters from the secretary of defense. Or the threats to destroy critical civilian infrastructure for water or power.

nemomarx•56m ago
Prisoner exchanges are a pretty strong motivator for any group, even hardline ones. If the Taliban was up for exchanges I think the IRGC is pretty likely to want to keep prisoners for that too.
mothballed•52m ago
I would note ISIS put out some high res, professionally edited video of burning a (Jordanian?) pilot to death while inside a cage. Quite savage, but the propaganda effect is more profound than about anything else I've seen.

thinkingtoilet•40m ago
There is no if. We've already done that. So yes, we are no better than them. So answer the question. Why would Iran follow conventions it's enemy that started a war of aggression is not following?
ofrzeta•33m ago
Becaus two wrongs don't make right. If they are smart they will stick to the convention.

MarkMarine•15m ago
I didn’t downvote you, but a terse “well actually it’s prisoner of war” doesn’t really add to the conversation. Imagine doing that in person, you’d annoy everyone around you. If you explained why it’s distinct and what that might mean for downed crew I think it wouldn’t have been down voted
bobchadwick•18m ago
There's a significant difference between a hostage and a prisoner of war, and in this context that distinction seems highly relevant.
NickC25•15m ago
...but we aren't at war, according to the President and his secretary of Defense (war).

what a fucking mess.

lokar•1h ago
Do they train for a “no quarter“ conflict where injured or surrendered combatants are killed?
rbanffy•49m ago
Hegseth is not in charge of the Iranian military.
lokar•45m ago
But he did publicly declare his intention to commit war crimes.
MarkMarine•48m ago
No, we actually train to be tortured and held if caught, but everyone knows the risks before you take off. Captured marines or soldiers have been killed in Iraq and Afghanistan, we’re clear eyed about it.
croes•45m ago

dmix•50m ago
It's pretty normal for planes to go down in a war. They've flown 5000+ sorties, it's a pretty huge accomplishment this is the first one lost over Iran. Especially considering all of the last decade's speculation about how tough attacking Iran would be.

You'll never be able to fully suppress all of their manpads. Even if you destroy the bulk of their air defence network.

josefritzishere•55m ago
This is the dumbest, most pointless military conflict in American history. There is nothing plausible to win, but we can conceivably lose everything. A pyric victory is among the most favorable outcomes. We are led by corrupt imbeciles. I can only hope the outcome includes regime change for the U.S.
karp773•53m ago
Why didn't Iran use its capability to take down enemy jets for an entire month?
karp773•49m ago
Downvoters, care to explain?

Seriously, it's been sitting on this for entire month and now, all of a sudden, rolled out antiaircraft defense? What's going on?

shigawire•43m ago
Because it obviously doesn't have the capability. Similar to how the US has no capability to "win" from the air only.
karp773•37m ago
Maybe it was friendly fire but I did not see that in the news yet.
DASD•24m ago
~15/16 MQ-9 Reapers have been shot down inside Iran. Not jets but still combat(strike and reconnaissance) aircraft.
karp773•13m ago
I just looked it up. Those are turboprop (slower) but have a high ceiling of 50k feet. So Iran did have something better than stingers left. Maybe they just got lucky this time.
eqvinox•19m ago
I didn't downvote, but your post sounds like you're implying some kind of tomfoolery, deception, or other hidden reasons. There are very likely none, it just takes time to adapt to a specific enemy, probability slowly increases while you get more attempts, and then after some time (t) the first shootdown is "properly" successful. And note how this was preceded by that half-successful shootdown where the plane made an emergency landing. And they shot down drones.

You sound like they roll an antiaircraft cannon out of the hangar and immediately successfully down a plane. That's not how that works. The AA was probably there from the beginning, just not successful.

vkr2020•50m ago
apparently, Iran is claiming that the search and rescue helicopter has also been hit by a projectile.
pwarner•48m ago
I hope the aviators are OK, and also hope whoever they were bombing are also OK.

I do wonder if Iran finds them first, will they treat them better than the US treated survivors of the ship sunk by a US torpedo in the Indiana Ocean?
