What role is the F-15EX supposed to cover that is not already covered by the F/A-18 F-22 and F-35?

Under the terms of the deal, Boeing will build a new version of its F-15, an older fighter jet developed in the 1960s, with new automated flight controls and electronic warfare capabilities. The newer model, known as the F-15EX, will be designed to carry heavier weaponry than smaller, stealthier jets like the F-35.

The Air Force is looking for a bomb/missile truck. They already have extensive experience with the F-15, and retraining(pilots/maintainers) and retooling to use the smaller f-18 would most likely cost as much or more as this deal. Also given military structure you would have to spin up a whole new command and maintenance Wing for the new type. Where the f-15 will just get added to an existing f-15e wings.

Like the Max?

> with new automated flight controls and electronic warfare capabilities.

Would this be good for making a drone version?

QF-4 and QF-16 exists for target practices but they don’t use them for any combat drone-y roles

The possibility of some fighters going unmanned and under the control of the ground or of another fighter in some scenarios has been discussed in other places, yes. It sounds like it's still in the planning stages.

The F-15 is one of the baddest planes in the air, and has been since its' first flight back in 1976, with an undefeated combat record. The radar capabilities are superior to almost all planes out there, which make it a damn good deterrent because they can reach out and touch you before you can see them. They have a wizzo in every situation, which offloads a lot of work from the pilot and lets them focus on flying the plane. I'm pretty sure none of the three you mentioned can boast those stats, so I'd say yes, give us more F-15s. The US has the most dominant air force in the world and I'd like us to stay that way personally. If you're upset about the government spending more money on new planes, be upset about the money wasted on the planes that aren't even flying, not our bread and butter.

> They have a wizzo in every situation

What do you mean here by "wizzo"?

Weapons system officer. F-15E is a two seat cockpit so you have someone dedicated to the weapons systems and someone dedicated to flying the aircraft at all times. I generally share the above commenter’s enthusiasm for the F-15 over the modern “replacements”.

>They have a wizzo in every situation, which offloads a lot of work from the pilot and lets them focus on flying the plane.

Isn't that only true of the F-15E? The F-15C/D that these are going to replace are single seaters aren't they? I'm having trouble finding detailed information on the F-15EX that specifies whether it's retaining the dual seat configuration.

Yes, you're correct, thanks for pointing that out.

I found some details here: https://en.wikipedia.org/wiki/McDonnell_Douglas_F-15E_Strike...

>> In 2018, the USAF and Boeing discussed a proposed F-15X, a single-seat variant based on the F-15QA intended to replace the USAF's F-15C/Ds.

Seems mostly like a stopgap to me. This is meant to replace a bunch of old F-15 C/Ds which are aging out of their operational life. The -18s are Navy, and so using them in the Air Force to replace existing -15s would be pricey on the logistics side, F-22s aren't being manufactured anymore and would far too expensive for the National Guard units these are going to, and the F-35s just aren't available in large enough numbers yet. The -15 has also turned into a very versatile aircraft, and it a lot cheaper to operate than a -35.

Part of the reason these old aircraft stick around is due to the very low risk involved with upgrades. We have -15s, we know they work very well, we know how to fix them, we know what to do with them.

A sibling commenter of yours pointed out that the EX variant will retain the dual-seat configuration of the E variant, which allows a dedicates weapon systems officer. An obvious fundamental improvement that can't be addressed through maintenance or upgrades of old variants.

> F-22s aren't being manufactured anymore and would far too expensive for the National Guard units these are going to

The 149th and 199th Fighter Squadrons are ANG and fly the F-22A.

You are absolutely correct, I should have been more clear that I meant they would be too expensive to go to the number of ANG squadrons that currently fly the C/D, I think they would have to double current F-22 numbers.

This sounds like the thinking that led to the 737MAX produced by the same manufacturer.

> The F-35 Joint Strike Fighter, on the other hand, can only carry four AMRAAM missiles in an internal weapons bay, a result of its need to fly without missiles and other equipment hanging off its wings to preserve its anti-radar stealth profile. […] The F-35 and F-15EX will likely fly in pairs, with the F-35 quietly detecting enemy fighters while the F-15EX services them with air-to-air missiles.

Gotta love that language of being "serviced" by air-to-air missiles. Hah.

"Dispensing product"

F-15EX is essentially a flying missile boat, I'm pretty sure it can hold up to 20 AIM-120 AMRAAM missiles. For context a 35 carries only 4. They will support f22's and f35's from BVR. The upgrades are probably designed to modernize the older air frame to talk to the newer ones.

Wasn't there talk of using the B-1 or even B-52 as an "arsenal ship" like that?

A F-22/35 goes in to find targets, relays them to the bomber, and the bomber slings missiles from BVR.

I think if any bomber were to be used in this capacity it'd be a B-21, stealthy, good capacity, but still subsonic so vulnerable. The range of AMRAAM is still considered being in the danger zone for those aircraft. I've used the F-15EX as a missile boat against China in Command: Modern Operations to great success. Some context I used to be in the AF and worked on raptors but, now it's more of a hobby. All information I'm discussing is gleaned from the Command simulation which is publicly available and a relatively good approximation of reality.

Dale Brown - Flight of the Old Dog

Yup, I remember this! B-52 armed to the teeth with AIM-120s. Later he has B-1, B-2, and F-111 versions too.

I remember enjoying his earlier novels. His later novels became both weirder and more political, so not much of a fan of them.

It has to be inherent in the genre. Clancy fell off a cliff in the mid 90's also.

Stephen Coonts was the most severe. His last Jake Grafton novel was absolutely cringeworthy - I say that as a (former) fan.

You're comparing the stealth configuration of the F-35 to the F-15EX. If the F-35 uses external stores it can carry 14 AIM-120.

Is that mode operational yet? I remember reading about it. https://www.thedrive.com/the-war-zone/17250/lockheed-touts-n...

That's to go from 14 to 16.

Anyhow, I know it's pointless to talk about this here on hnews, because the smug crowd that's read one or two articles on war is boring or such drown everything out, but I've seen this issue discussed by actual military aviators at length, and they were overwhelmingly of the opinion this F-15EX buy is a bad idea, and basically just a pork politics attempt for Boeing to pull some more cash their way.

Interesting I'll have to ask the guys I know at ACC. I mostly play with the planes in sims and they seem useful. The dollar amount isn't really a consideration then.

Most the guys I know think throwing away f22 production was the dumbest thing we could have done.

It's hard to interpret destroying the F-22 tooling as anything but malicious rent seeking imo.

> What role is the F-15EX supposed to cover

The corporate welfare role

That's a better argument for the F-22/35 programs. The F-15 is a workhorse, and this is an extremely inexpensive upgrade program relative to building an actual modern replacement, or buying F-35s and calling it "good enough."

The question was roles not covered by the F-22, F-35, and/or F/A-18, so that response isn't quite on point, even to the extent the F-15EX might also serve that role.

Nah, that's the F-22 and F-35.

This is the cheaper, "upgrade the old system" option.

And no matter what aircraft we buy, we're still in the AFG and Iraq, goin on near 20 years for the former. This is a drop in the bucket compared to what we're paying to stay in those countries. The medical care for OIF and OEF veterans will be north of $1 Trillion...

I'd add to this the unmanned combat planes like the Predator.

As unreliable as Wikipedia can be, the unit cost of the newest upcoming Predator (Predactor-C, or Avenger) is $12-$15M each. Which is 10X cheaper and moreover easier to scale, e.g. easier to train ground personnel than pilot. https://en.wikipedia.org/wiki/General_Atomics_Avenger

The real kicker is the U.S. military spending is already more than the next 10 countries combined....so what is the F-15EX supposed to be fighting against? Sure it's a much better deal than the F-35, but the F-35 is already a giant money sink so not saying much...

> Sure it's a much better deal than the F-35

Maybe if they build more of them and the price comes down, but 8 for 1.2 billion is 150 million a piece and the f-35 costs 78-101 million a piece depending on the type [0].

Nothing. It’s a jobs program same with the F-35 as China/Russia/Iran doesn’t want to start a war, they would much prefer to cause chaos in the elections. When we can spend way too much money on these corporate welfare vehicles, but can’t even make enough simple N95 masks. I’ve lost faith in this country.

Probably an Air Force equivalent to the Navy's EA-18 Growler.

The Growler is basically an F-18 Hornet, so it's maneuverable like a fighter (and can engage in limited combat), but is refitted with equipment for electronic warfare missions and roles (radar and comms jamming, intercept, etc...).

The Air Force F-22 can already do some EW, but that is not the F-22's primary role or specialty. Also, there's a limited supply of F-22s and they are very expensive to operate and maintain compared to F-15s.

So, this new F-15 does seem fill a niche where F-22s would be overkill and Growlers unavailable (since they're Navy aircraft built for carrier operations).

I believe the F-35 was supposed to have a SEAD variant or "SEAD-mode". The F-4 Wild Weasel filled that role for a long time until the AF gave up on SEAD and handed it off to the Navy with the EA-6B Prowler. The Prowler did well and was replaced the Growler which has a decent reputation (or so I've heard).

Given the mess that the F-35 has been, I'm in agreement with the parent -- this may be a recognition that the AF needs a EW/SEAD fighter like the Growler and the F-35 will have some limitations.

The F-15 also has some serious combat persistence, which isn't terrible for an EW/SEAD craft, esp. since anyone thinking about fighting the US is investing heavily in AA, both in technology as well as sheer volume of systems. Having a big "missile truck" with EW makes squashing all of those systems a little easier.

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

Disclaimer: I'm legally still a Whidbey Island WA resident and have connections to the Growler project. However, the above points are simply opinions.

f-15 is airforce, f/a-18 is primarily navy and suited for their roles.

F-22 is too expensive to use most of the time and we are having a VERY hard time keeping the fleet operational.

F-35 has basically been a giant cluster. But getting better.

The primary role of the F-15EX program is to keep aircraft defense manufacturing viable.

And ultimately:

Although Air Force leaders at the time said that the service would have preferred funds to buy additional fifth generation planes like the F-35, officials now say that buying new F-15s is the quickest path for replacing aging Air National Guard F-15C/Ds that are reaching the end of their service lives.

“The F-15EX is the most affordable and immediate way to refresh the capacity and update the capabilities provided by our aging F-15C/D fleets,” Gen. Mike Holmes, Air Combat Command commander, said in a statement. “The F-15EX is ready to fight as soon as it comes off the line.”

> officials now say that buying new F-15s is the quickest path for replacing aging Air National Guard F-15C/Ds that are reaching the end of their service lives.

Does this mean the F-15EX will deploy to ANG squadrons, or does it mean that the Air Force planes which are displaced by new F-15EXs will deploy to ANG squadrons? Just curious.

The F-15(E) is the only aircraft capable of carrying the bigger munitions and in large quantities including the heavier nuclear gravity bombs that isn’t a strategic bomber.

With the F-14 gone and the F-111 gone the US doesn’t have the ability to drop big heavy bombs outside of using a B-52/B-2/B-1 bomber.

The strike eagle is aging and the F-35 isn’t as suited for ground attack missions.

> The strike eagle is aging and the F-35 isn’t as suited for ground attack missions.

Ground attack is literally the reason the F-35 Joint Strike Fighter exists, so it not being as suited for it as an upgraded F-15 is a pretty big indictment of the program.

It’s as suited as the F-16 it’s a small multi role fighter I don’t think you understand just how much bigger the F-15 is.

Your picture didn't really help me visualise. Roughly halfway down this thread though... http://www.f-16.net/forum/viewtopic.php?f=63&t=55069

Yep that’s the kind of picture I was looking for but couldn’t find on google images.

> It’s as suited as the F-16

That's also a problem, since we’re talking about it's core mission where it's supposed to be a more capable replacement for the F-16, and is several times as expensive (both initially and per flight hour).

It’s more capable because it has better avionics and electronics, the F-16 just like the F-15 still needs a targeting pod for many ground attack missions.

The F-15E was built for air interdiction to replace the F4/F111 it has a better radar (especially for ground attack), a more sophisticated electronics warfare system and more busses for high bandwidth electronics such as targeting pods than it’s air superiority brothers.

The F-35 is an advancement over the F-16 it was supposed to be and is a relatively cheap (for a 5th gen fighter) multi-role platform it’s more advanced than the F-16 in every aspect for example much of the capability that a targeting pod such as the LITENING provides is integral to the F-35 and the fact that it carries about 2.5 times the fuel than the F-16 means it can carry much more munitions instead of fuel tanks (F-16E/F with conformal fuel tanks comes closer without expanding hard points)

What you can’t change is it’s main characteristics and that is its a single seat single engine multi-role fighter so regardless of how more advanced it is it simply doesn’t have the hard points due to its size and due to the fact that it’s a single seater it is more limited than a two seater aircraft when it comes to operating in denied airspaces and missions that require a pilot and a weapons officer.

Saying that it’s a problem because the F-35 is more expensive currently is nonsense the F-16 is the most produced fighter of the modern era comparing its cost now to the F-35 is silly.

The F-35 is unquestionably more capable than the F-16, but it doesn’t mean that the US currently doesn’t have a gap in its capabilities specifically for interdiction and deep air support missions.

During the early to mid development of the F-35 an F-35E was considered it was to be a larger two seater variant of the F-35 without S/VTOL capabilities to replace the F-15E but due to the cost and lower part commonality between it and the rest of the F-35 line up it was abandoned.

The impression I got from reading the pitch on the official Boeing site was essentially: "You are mandated to buy 72 planes every year, how would you like to buy a cheaper plane? We'll even throw in some extra kit!"
