Namor's strength underwater is rated at 85 tons and Iron Man's suit at maximum output is the same. So if it came to a physical fight, the one with the better moves would win, probably Namor since the armor might be slow and clumsy (spelling?) underwater. But Iron Man's armor is not without it's accesories. The Hydro armor is able to resist 8,000 lbs/sq. in., is powered by a micro nuclear supply pack, and has repulsors, mini-torpedoes, and an electric field generator (the armor can generate an electrical field around itself similar to an electric eel). Close fight.
Namor has little known and little used electrical powers similar to electric eels so that aspect of the armor wouldn't help Stark. Namor also has limited invulnerability, so it would take awhile for the repulsors to seriously hurt him. In that time, Namor peels Stark out of the armor like a sardine. PUN!

Stark needs to develope a sientific equlivant to Juggernauts helmet magic so he can't be ripped from his armor. In the air Ironman even though it would be closer, on ground Ironman definatly. Underwater I think Namor has all the moves so it goes to him.
Iron Man can't be "ripped out" of his armor. If your talking about the psi-defenses of the juggy helmet then, Iron Man has that area more than covered. He was immune to world level controlling psi.
Why are battles that have already happened in the Marvel universe posted here. It's just a waste of time to rediscuss something that already happened so far back.
Iron Man would win in the air/ground, that's where he is most specialized, Namor; however, would win 9/10 battles underwater.
Iron Man can out-fly Namor and is equally as strong (without being connected to a powerful energy source). Iron Man wouldn't run out of energy that fast, maybe his main power supply pack, but he has solar energy converters as back-up.
If Namor is getting dehydrated and wanted to go back into water Iron Man would simply hold him back, since Namor's strength has gone down significantly, and beat his face in.
