Doesn't even have to technically be contragravity. If you have a reactionless thruster that can produce more thrust than local gravity with (minimum) weeks of endurance, you can fly straight up through the atmosphere at any reasonable speed you like. You don't have to use your max acceleration if you're not in a hurry. If your hull generates any aerodynamic lift, then you don't even need full local gravity, yet still don't have to fly through the atmo any faster than normal aircraft do to generate that lift.

You have to reach orbital velocity to stay in an unpowered orbit. But the >1G ship can hover, whether that's 1m off the ground or 100,000.
