fastest jet in ksp *UPDATED* 2/28/2019

Recommended Posts

2422.0m/s (8,719.2km/h or mach 7.1)

That's orbital velocity... while the OP hasn't really mentioned it... the leaderboard is all SURFACE velocity. So that puts you at about 2200 m/s, pretty quick... but definitely not the fastest.

Roflcopterkklol I need to see the surface speed I don't take orbital speeds but good try though:cool::wink:

:o i thought orbital speed was acceptable considering you made the altitude limit over 36km (36km is when it changes from surface to orbit)

should change the altitude limit to 35km if that is the case, just sayin, can i be descending when i reach my highest speed then?

If you click on your speed it changes from orbital, to surface, to target speed (if you have one).

You can be wherever you want to be when you take the highest speed, just never ascend over 40km in Kerbin's atmosphere. That means that you can't launch above 40km just to drop back down.

2339m/s as seen in the first picture, the second picture was taken a second later to show the craft.

Even breaking Mach 5 seems very difficult to me in stock 1.0.4. Got to Mach 4.99, but may be using a bad approach...

My fastest design has achieved 1376.8 m/s, after babying it faster and faster for a good 15 minutes until it finally gave in to the heat.

Quite a bit short of the 0.24 records, but I guess it makes a good enough starting point here in 1.0.4.

While Mach 6 still seems out of reach, Steltina and Halrim Kerman made it to Mach 5.02 (according to Kerbal Engineer Redux), or 1482.6m/s in level flight.

@Lego_8bit : You write "allow opt mod Aka the ADVANCED TURBORAMJET! and the scramjet mods" and "DRE".

I have no idea about these. Could you please explain further, e.g. by providing links to these mods?

i will indeed thanks for the heads up also DRE is deadly re-entry

Thanks for the mod links. I just tried the scramjet mod - it gets really wild!

While "surface" speed was still displayed on the navball, I reached Mach 8.01 / 2557.6 m/s:

And just before reaching the 50K ceiling, Mach 9.01, and 2701.5 m/s displayed by Kerbal Engineer Redux:

The ship went into a high atmosphere-grazing orbit, and only re-entered after the second orbit and was able to glide to a landing you could walk away from near KSC.

Mother of god...... you surpassed all the 24.1 speeds!!!! im gonna need to set a different bracket up for mods (replacing the far one) I will get your icon made right away :D

1. MAX ALT is 50,000

2. Updated* Due to the atmospheric update i will allow opt mod Aka the ADVANCED TURBORAMJET! and the scram jet mods or stock only! (But DRE and Is Permitted to show Accurate mach speed)(also FAR is permitted I will have a separate speed category for FAR entry's)

3. No rapier engines

4. No rockets of any kind

5. UPDATE* You my use jet, turbojet, advanced turboramjet, and scramjet mod ONLY!

6. SURFACE SPEED ONLY

NEW RULE** you can have up to 1-8 Air intakes.

And no thrusterless jets

No Ctrl alt f12 crap either

You must take a screenshot of your alt and your speed and also proof of no cheats

TOP SPEED IN STOCK 1.0.4:

1. norup made it to Mach 5.02 and has a speed of 1482.6m/s

2. fire219 made it to Mach 4.96 and has a speed of 1376.8 m/s

3. Zaddy23 made it to Mach 4.92 and has a speed of 1365 m/s

Well, here's my quick attempt at a speed flyer:

I think if i build a proper racing rocket (see Kerbin circumnavigation challenge thread, there are lots of those) speeds of over 1700 are easily attainable.

Good attpemt try to fly a bit higher though you will gain a lot more speed .

the speed limit appears to be about Mach 28 at 30km. At which point, you're at Kerbolar escape whether you like it or not and you fly off in a straight line.

(source: did it with a nuclear engine).

interesting you were testing the mach speed limits and you managed to get to mach 28 in 100% re entry heat?

I will be shocked if anyone makes it to mach 28 on an atmospheric engine.
