What was your highest velocity ever achieved?

[The Aziz]

No matter if achieved by regular means of propulsion, by cheating (meh) or due to Kraken.

Today I just broke the universe 44 million times. That is over 13 quadrilion meters per second. Thanks, Kraken.

I had a plane in ~.23 reliably fling a parachute so fast that the numbers on the speedometer went off the screen.

[NSEP]

Idk, like 20km/s? 

[tomf]

I once crashed a probe into Moho from a retrorgade hyperbolic Kerbol trajectory. That must have given me a relative velocity of about 35 km/s. That was with slingshots around Jool and without cheating/krakens.

[joacobanfield]

80192 m/s, via Kraken. I just EVA´d when my ship was spinning a little bit too fast...

[StupidAndy]

I glitched an asteroid and managed something like 50,000 m/s? I forgot

[n.b.z.]

I don't remember any numbers, but I'm sure I have never gone as fast as when trying to get into a Moho orbit for the first time.

The velocity at which I screamed past Moho was unbelievable.

[max_creative]

NotFastEnough m/s.  

[DarkOwl57]

Somewhere in the 100 mil m/s range. BDArmory glitched out and a Maverick missile hit the speed of light.

[TheKorbinjer]

Powered? 16% speed of light. had something accelerate at like 30 km/s^2. Crashed it into the sun. 

accidental? speed of light squared and a half I think

For me 600.000 ms during an interstellar travel in RSS, using an Interstellar Extended engines. Way slower than the Kraken obviously.

[cantab]

Legitimate, probably my Sun impact probe but I don't recall the exact speed. Second place I hit Jool doing 40 km/s courtesy of Near Future. Also notable is that just leaving Earth's SOI in RSS will immediately give me about 30 km/s.

With infinite fuel, 23% of light speed:

This was done exploiting the old physicsless parts behaviour. It's just a single octag strut with a bunch of puff engines hanging off it and a few struts to brace it, all physicsless in that version of KSP, and that's how it can reach such extreme accelerations. No probe core - only way to control it is to turn fuelhack on or off.

Never question a Maverick. 

[cubinator]

I once accelerated a pod with Puff engines and infinite fuel towards Jool from Kerbin, and it was going so fast it bounced off.

Yup. It almost crashed into the mountains next to the KSC (missed it by *that* much), and after turning No Heating on, I just went and took a nap. 15 minutes later, it was out of the system, at 125,000,000-ish m/s, and I finally reverted flight (Val and Bob died in the plane that the missile was fired from)

With the kraken? 17882467941956912857218016537951256216593563208956287016589031222222651890568961296856610001010849324016580236532568265217561427805281065 m/s. Something like that.

Without cheating? Something like 30 km/s? Idk exactly.

Excuse me? 

[GDJ]

With mods? About 20X light speed.
Stock? I think about 20 km/sec (close perigee around the sun)

[ProtoJeb21]

Back in 0.90, I was bored and decided to tweak some parts. I increased the thrust of the 3.75m engine now known as the Rhino. And by increased, I mean multiplied it by five times . So I took a small rocket, only a capsule and that engine, turned on infinite fuel, and flew. My max speed: at LEAST 120,000 m/s.

But recently I blew that out of the water.

I was testing the horrifying abomination of nature neutron star Lich, and I was getting my craft closer and closer to it. My ship was completing one orbit every 80 seconds, and the gee-forces were over 14,000 times that of Kerbin. So I had the bright idea to EVA my Kerbal...and went accelerating into oblivion at 299,999,000 m/s - 99.99% the speed of light 

[ProtoJeb21]

Guess what? I broke my record  

So I was testing a planet for Kluster and I wanted to get down faster. So I increased gravity with the cheat menu, and then this happened:

And then this:

And then *CRASH*

[hrobi2]

20,000m/s in real solar system

[purpleivan]

Just under 91km/s flinging a vehicle close around Kerbol.

 

The fastest I've gone without using the sun for extra speed was 36km/s.

This got a Jeb to Eve in 5 days 1 hour, although this was in the old days before serious atmospheric heating, so I just slammed his vehicle into the thick Eve atmosphere at that speed to slow it down.

 

 

[nascarlaser1]

fully stock (not cheats/kraken/mods) plane hit mach 4 and half 30 meters above sea level on Kerbin, before I accidently pointed upward and the g-force ripped the wings and cockpit off, hurling it into the ocean. This was after its predecessor hit mach 4, but burnt up 60 meters above the water. The predecessor had a heat shield strapped to the front to keep this from happening.
