Wikipedia is your friend.

See http://en.wikipedia.org/wiki/Comparison_of_orbital_launch_systems and sort by launch count.  Soyuz wins, hands down.

Kerosene - Soyuz, Atlas, Thor/Delta

edit: I thought he was referring to most used propellant

Soyuz is the most launched vehicle for orbital flights

[IRobot]

Probably the V2 rocket. Around 3200 launches.

EDIT: not enough to achieve orbital speed, but enough to clearly go to space.

In terms of all launches, both orbital and suborbital, as of the end of 2013, including any launch vehicle that also served as the basis for an orbital launch vehicle.

1.  R-7: 1810
2.  R-14: >903
3.  Thor:  719
4.  R-36:  610
5.  Atlas:  582
6.  Proton:  393
7.  Titan:  368

In terms of orbital launch attempts only, as of the end of 2013

1.  R-7:  1755
2.  Thor:  606
3.  R-14:  462
4.  Proton:  392
5.  Atlas:  326
6.  R-36:  277
7.  Titan:  219

If you allowed solids, Minuteman would be number 3 on the total list, with 884 launches.

Give or take, of course.

How many Scuds were fired in history?

Thanks, Ed.  This needed a little definition.  I imagine the OP was thinking along the lines you suggest, but you could take this to such extremes as counting as a "launched liquid fuel rocket" each individual liquid-fueled RCS or attitude control motor launched as part of any spacecraft, manned or unmanned.  Much less maneuvering motors.

If all you're looking at is the launch of a liquid-fueled rocket from the Earth, no matter whether the rocket was ever designed for orbital operations, then you do have a whole class of short-range weapons for which to account.  V2's in that case would likely take a lead, but you would then add in all the various versions of the Jupiter, Redstone, etc.  And a few classes of Soviet missiles, plus SCUDs, North Korean bottlerockets...  Basically, the IRBM class, in its many forms.

Good thing that early cruise missiles operated mostly with jet engines (often combined with SRM launch stages), or you'd have yet another class or two with which to contend.

Ah.. I see.
I was reffering to liquid fuel rockets with orbital capability without the use of solids for ascent.

In the line of this. Could RD-107 be the most used liquid fuel rocket engine?

[Jim]

funny, but those are probably less than even Titan orbital launches.

As a side note, LOX would be the most used liquid Oxidizer.

Other than Solids, Titan (II-IVB), Black Arrow, Proton, Tsiklon, R-29, Ariane (I-IV) and various upper stages (Agena, Able, Delta II upper stage, Briz-M, Blok-D), LOX has been used for everything.

Though I suspect the majority of HEO upper stages have been hyperbolic. Only Ed. would know for certain.

You're right.  Redstone only flew 100 times, and only 7 times on orbital attempts.  Jupiter lifted off 46 times, with 10 orbital attempts.  They both seem to loom larger than that in historical memory.

In the United States, the IRBMs were quickly replaced by "hidden missiles".  Those are the launches that have no webcast coverage, and sometimes no press releases at all.  If you put all of the Navy's SLBM tests together (Polaris, Posiden, and Trident 1&2) the total exceeds 1,200.  (I've always been amazed that the very substantial infrastructure used to build and test these missiles remains largely hidden and rarely discussed.)

Once deployed, they no longer need land based pads for tests.

Don't forget Long March.

Right.  All DF-5 family launches totaled at least 207 at the end of 2013, including 194 orbital attempts.  The DF-5 orbital total will likely pass Titan's number in the not too distant future.

RD-107 is the most used liquid fuel rocket engine for orbital capability boosters?

How many Scuds were fired in history? 

I think more than 6,000 Scud missiles have been launched throughout history, far greater than the more than 3,000 V-2 ballistic missiles fired against London and the Low Countries in WW2. It'd be interesting to see how many test launches of the Scud were conducted, and how many Scuds were fired during routine military drills, but according to a 1993 working paper, more than 2,000 Scuds in use by the armed forces of the communist government in Afghanistan were fired against mujahideen positions in the country, Iraq fired 277 Scud missiles at targets in Iran, Saudi Arabia, and Israel during the Iran-Iraq War and the 1991 Persian Gulf War, Iran fired 77 Hwasong-5s at targets in Iraq, while Syria launched over 30 Scud missiles at targets controlled by groups opposed to the government of Bashar al-Assad.
