That would be great, ASM-3A if wiki is right is already ~400km range
Yeah ASM-3 Kai is like 600+
Correction, ASM-3 uses liquid fuel for its ramjet, and did not appear to follow along with the research done for solid fuel ramjets the AAM-4 prototype started.

which one is better for speed/energy?
After all it’s just a AAM-4B radar programmed to seek for different (ship) targets.
Such speed isn’t required for an air to air missile I think, if the thirst is on for a big part of the flight. (Ramjet)
same speed, mach 3+?
What differences does it brings ? Liquid fuel would be easier the throttle?
Yeah
There are hyper sonic Air to Air missiles in development apparently USA is concerned about Chinese developments though there more focused towards anti awac / tanker planes.
solid writeup, but one nitpick: ASM-3 (and the Kai/ER) isn’t actually a scramjet. every source on it, Naval News, Aviationist, ATLA/MHI stuff, calls it an Integral Rocket Ramjet, so a solid rocket booster gets it up to speed and then the same chamber just switches to burning as a regular ramjet, tops out a bit past mach 3. basically the same setup as Meteor and ASMP-A honestly, which you already brought up.
and it actually fits your own chart lol, scramjets only start being worth it around mach 5-6+, that’s the point where slowing the air down to subsonic (which is what a ramjet does) starts costing more than it saves. below that a ramjet’s just the better option, not some “lesser” tech they settled for. so something topping out at mach 3 has no real reason to run a scramjet, it’d actually be worse off doing that.

the real upgrade is RDE ramjets

a man of science, altough the only rotation detonation engines japan has are for JAXA i dont think there is anything for japanese missiles, and they seem focused in making really efficent rocket engines using CFRP

lockheed and GE making one for missiles, hopefully they flight test it soon
Its very funny, the one document that mentions scramjets and the ASM-3 kai together, which is often cited as the source for the claim that the kai will get a scramjet, actually explicitly said that scramjets wouldn’t work on it and they’d need an entirely new missile.

i know what doc he is talking about the doc mentioned the usage of scramjet but was deemed unviable for ASM-3 like most TRDI it only ever ends up in something else after a few years
thanks, took me some time :D
Thank you for the scramjet precision, I’ve deleted anything I’ve said in there about the ASM-3 Kai, since the only info I’ve seen (and missunderstood) was just as a quick ‘funfact’.
Sadly I don’t think I have the required knowledge to write anything about scraùjets engine, so I won’t go much in those, which is the main reason I prefered to delete instead of edit anything about the 3improved variant.
I don’t have much time to dive into it with the starting of the new year at univ.
But is my suggestion having imprecision/mistakes about the ASM-3A ?
I feel like (from what I"e seen in vid’s about the ASM-3 that just have been implemented in the dev server) it is very poorly implemented ?
dont worry people rarely tend to diffferentiate between the 2 and even i took a bit to find to find the difference
scramjet dosent slow down the air before entering the combustion chamber it uses the supersonic air and pushes it straight out, only issue is that it dosent work below mach 5, that’s the basics of it, ramjet does have to slow down the air wich only looses efficency after mach 4, altough its still viable up to mach 5 the sweetspot its normally mach 3.5
ASM-3A as far as i know its just a range increase from 200 to 400 km, they might’ve tweaked engine flight profile or something else, while ASM-3 KAI is also supossed to increase range and have it doing double purpose as a tanker/AWACS killer
