Zero acceleration — and therefore zero net force (and constant momentum).

Reason: acceleration is the rate of change of velocity; if velocity (magnitude and direction) is constant, its rate of change is zero. (This applies in an inertial frame; note that constant speed with changing direction — e.g., circular motion — is not constant velocity and does have acceleration.)
