I saw this from a few months back from Scar.

Can someone here please translate and summarize the specs? Thanks.
So here’s the image of how the F-35 compares, keeping in mind that this is with the 7g control law limit.
To summarize the air-to-air combat configurations used in the comparison:
F-35A: 13,000 lbs internal fuel (to simulate half internal fuel plus weapons)
F-15C: fuel tank racks, air-to-air missiles (presumably)
F-15E: targeting pod, rails and racks (almost certainly on CFTs), air-to-air missiles
F-16C: HARM targeting pod, IR targeting pod, ECM pod, rails and racks, air-to-air missiles
A-10: IR pod, ECM pod, rails and racks
No engine configuration given for the F-15E and F-16C.
My observations: speed recovery advantage of the F-35A vs F-16C seems to show that all the targeting pods have substantial drag. F-15C was probably the most unencumbered.
It will be interesting to see what an up-engined F-35 can do. If I recall, the F135 isn’t making full use of the F-35 inlet, since there’s currently enough flowrate to accommodate a more powerful motor. Block 1 improvement of the F135 that (if properly funded) should be in service in 2023 is supposed to provide up to 47,300 lbf of thrust, so it will be interesting to see what an F-35A with full 9g envelope and Block 1 F135 would do.
Overall the F-35 seems to have roughly similar maneuverability as 4th generation aircraft. It’s may be nothing special, but it will still be very dangerous in a dogfight.
FYI MAWS/MLD are switched off on fighters in simulated fights vs F-35
Source?
on the contrary there is on this forum only two that think J-20 is a better fighter than PAK-FA,
they all fall under the ‘moderate observable’ category btw
Moderate observable? What does that even mean?
The Oniks is a 6000 lbs missile using a 550 lbs warhead with Mach 2.5 speed, so close to 2700 km/h. And that’s the speed it strikes too, so in terms of kinetic energy, especially at close range when it had more fuel onboard, it vastly outdo the Mark 8 shell from a 16 inch gun. It may not have the hardened tip but it’s sheet kinetic energy will do the job.
All armor is not equal for one. The 1.5 inch STS was deemed sufficient to decap an AP shell or redirect it to a less optimal penetration angle. This was tested, not opinion.
No, that was based on the old emperical formula by Nathan Okun that is no longer valid. Here is his updated analysis, and based on email I’ve had with him it takes over 2 inch of STS to decap a 15 inch AP shell. The current 1.5 inch STS will only decap if strike angle is greater than 15 degrees.
The Hood’s belt was different armor, narrow and tapering below waterline. Totally different armor scheme that was inferior to plunging fire. The RN knew this at the outset of WWII, events meant that the Hood’s armor was not modified. What happened?
Iowa’s armor also tapers below the waterline, so I’m not sure what point you’re making here. The Hood is essentially an upscaled version of the Queen Elizabeth battleships, and in any case it’s the thin deck armor of the Hood that was it’s undoing.
Not sure what you are smoking here…. The 2,700lb 16″ shell fired from the 16″ 50 caliber had a velocity of 2,500 fps (2,743 km/h). No contest in kinetic energy.
That’s the muzzle velocity. Actual striking velocity on deck will be much lower since the projectile is plunging.
A modern supersonic AShM will mission kill any WW2 battleship, if not outright wreck it.
You can’t shoot if you can’t see, and all the armor in the world is useless if your fire controls and radars remain vulnerable. You lose those, then you’re just a big punching bag with no relevance in combat. Now, some degree of protection is necessary to ensure that you don’t lose your crew and what not in a single hit, but going back to battleship level protection is silly. Which is why modern warships are more about having smaller ships that spread out your fire power and focus on not getting hit in the first place.
Iowa’s armor was not spectacular. Just look at its size, displacement, installed machinery weight…expecting magic is silly.
Littorio’s decapping scheme probably gave it more effective armor. Iowa had a weaker belt than KGV. Richelieu had somewhat better protection than South Dakota, and Iowa had the same scheme as SoDak (with same deficient torpedo protection) just on a much larger hull….
Iowa’s outer plate isn’t for decapping, though it and another layer of high tensile steel plating still adds somewhat to the effective armor thickness, and the inclination also complicates penetration, especially at longer ranges with steeper plunging angle. Richelieu’s belt is similar to the Iowa and South Dakota though without the additional high tensile steel plating and thinner outer plating. It has exceptional deck protection too. I realized I left out the KGV earlier, and the side protection of these ships are arguably second only to the Yamato (possibly more due to quality of British steel, considered best in the world), with subsequent Lion and Vanguard having thinner belts (still external and fully vertical). There’s also isolating magazines and thickness of armor between magazine and other compartments, which the Iowa and KGV do a better job of than others. The use of armored belt on the South Dakota, Iowa, and especially Yamato (due to greater thickness of said belt below the waterline) does modestly downgrade explosive proof rating, though liquid loading certain voids help mitigate that. That being said, the same belt armor under the waterline allow these three ships to have the best resistance to underwater shell hits, though those aren’t particularly common. Nathan Okun provides a good analysis of battleship armor, focusing on the Bismarck but also giving insights on KGV, South Dakota, Richelieu, Vittorio, and Yamato. Some of the decapping information is outdated but much of it still holds.
I know fellow American posters think fondly of the Iowa, but in pure protection terms she’s nothing special. She’s well protected and comparable to her contemporaries, but that’s that, and there’s nothing remarkable about it.
Anyways, all this is academic and not relevant to today’s combat. Being armored doesn’t mean anything if you end up getting mission killed in the first place. South Dakota’s electrical failure in the naval battle of Guadalcanal shows that.
Even the Yamato would be easy prey to today’s weapons. Something like the Mk 48 that detonates under the hull of the ship to destroy structural strength is enough to outright mission kill a battleship in one hit.
The Iowa’s armor was overrated even then, let alone in 2016 😉 .
Iowa and Vanguard are probably tied for the second best protected BB after the Yamato, not like that even matters anyways.
I don’t know why people here even take blackadam seriously. Does no one here remember the stupid topics he made before? Like some of the following.

since they are anyway late: why not GaN aesa to nullify moderate levels of stealth ?
What are moderate levels of stealth?
The F-15 arguable is the West’s Flanker analogue. It has smaller dimensions, but in terms of speed, range, maneuverability, etc, they’re quite close. The F-22 is not even in the same weight class as the Su-27, nor does it carry as much fuel. The F-22’s subsonic combat radius is about 590 nm, with a 6% rerouting factor. Doubling gives range of 2,325 km, which is pessimistic since it doesn’t take into account combat. Supersonic range is a bit hard to find, the range slide shows 460 nm combat radius with 100 nm supercruise, but it’s not known if it only supercruises one way or both. I think back in 2009 AvWeek stated that the F-22 has 37 minute supercruise (correct me if I got this number wrong), which I assume here to be at Mach 1.5, which gives about 928 km at altitude. This works out to be about 42% of the subsonic range, which is quite a substantial drop, but something that’s expected.
For comparison, the T-50, which carries even more fuel than the Su-27, is stated to have 3,500 km subsonic range and 1,500 km supersonic range. Turns out that the T-50’s supersonic range is about 43% of the subsonic range, which is quite close to the F-22’s.
Do you see the slide above? I am pretty sure that the people who have been working on this project the last ten years, including building test articles, and who just received a billion dollar check to continue their work are aware of the constraints their engine will face in an aircraft.
Why should I believe you over them?
I’m pretty sure djcross is one of those individuals in the know, based on the posts I’ve seen from him.
But still we don’t know what GE is comparing to when they list improvement numbers. They might have already considered the inlet losses and other concerns. Also, if I remember correctly the F135 isn’t making full use of the mass flow of the current F-35 inlet.
1] where are you pulling 150 nmi from ?
2] he clearly states that its not supercruise in a technical sense, that leaves only a/b or dive, or deceleration
1. I reread the source and realized the pilot said mi, not nmi, though considering how common nautical terms are in aviation it’s difficult to be certain. Either way I stand corrected.
2. What’s the “technical sense”? The pilot even clarified what it meant, a dash of 150 miles using min (zone 1) afterburner. Which is distinctly different from max afterburner. I’d hope at this point you’re aware that afterburners have stages. I don’t even know how you managed to interpret dive from that statement.
he can dive from 48k to 15k, an interval of 33k ft, but i think haarvarla hit the nail:
f-35 can fly at m1.2 150 miles on a teeny weeny bit of a/b, which is very different from using fuel gulping a/b 😉
before running out of fuel.
not bad at all for a non supercruising machine, about half as good as the arguably best in the class
Do you even know what afterburner stages are? And where are you pulling the 150 nmi before running out of fuel out of? And where does it even say the aircraft was diving?
ok, so f-35 cant go m1.2 below 30k ft, that is troublesome indeed, is there any other fighter that ever had this limitation in history ?
anyway, the most likely is that he didnt count ‘a teeny weeny bit of a/b’ as ‘fuel-gulping a/b’
This is the Dunning-Kruger effect in action.
Su-27, max speed at sea level 1,400 km/h, or Mach 1.15. Same for MiG-29M. That took about 10 seconds to dig up from KnAAPO and MiG brochure. But name a combat-configured fighter that can hit supersonic in military power at sea level. Aside from the F-22 and perhaps T-50 your list runs thin. Are you even aware that afterburner has stages? It’s not a simple on/off thing.

PAK-FA extremely fast climb speed.
Parts of that video are definitely sped up.
