You have the specs backwards. Ariane V is the one on the bottom.

How does the proposed Falcon Heavy stack up to these two?
|Quoting BigJKU (Reply 6):|
If you are new to evaluating the capability of space launchers the main number to look at for an evaluation is really the overall weight of the assembly. Most of the physics are pretty fixed with such systems. You burn a given amount of fuel to move a given amount of mass a given amount of distance. The variables are really in when the stage cutoffs are and how light one can make the rocket itself. So long as someone is burning fuel and shooting out the bottom of the rocket though the general rule will be the bigger the payload and distance traveled the bigger your rocket will have to be.

The Merlin 1D really shook up the game.

Spacex shows how they think Falcon Heavy stacks up to the competition at http://www.spacex.com/falcon_heavy.php .
|Quoting travelavnut (Reply 11):|
So what's so special about the 1D?

So what's so special about the 1D? I've read Elon Musk bills himself as the Chief Designer. Find it hard to believe someone with little experience can shake up the game
|Quoting Aesma (Reply 9):|
There is/was a debate about upgrading Ariane V or developing Ariane VI and Ariane V won so an upgrade is being done. Didn't I read somewhere that Atlas was too expensive for commercial use ?
|Quoting autothrust (Reply 12):|
Good question specially because it is a weaker engine compared as for example Vulcain 2 or RD-180 AFAIK??
|Quoting nomadd22 (Reply 13):|
Musk is known for Paypal, but has several engineering degrees and knows his way around the shop. Tom Mueler is the guy behind the engines. Elon doesn't pretend to be the genius behind the details, but he is very much into design decisions and is familiar with the launcher down to the last bolt. He's not just some CEO who said "Build me a big rocket"
|Quoting Areopagus (Reply 14):|
The fuel tank is bigger and needs insulation, which translates into weight, drag, and cost.
|Quoting autothrust (Reply 16):|
I'm really wondering about the Ariane having almost the double the mass of the Atlas V. Does this insulation make that much difference?
