Ya, Proportions' self-defense cannons (SDC) can intercept seekers at range one, as they come in. Their reduced accuracy compared to PDC, and the improved fighters modifiers, mean missiles can be stopped by the SDC or PDC, but fighters can remain a viable weapon even into the late game.

Proportions also has light missile systems, however, which can increase missile rate of fire by up to about 4x by launcher mass (but for less damage per shot).

Although directional shields aren't in SE4, they can be thought to be abstractly included in training. A superior captain could be represented by a ship and/or fleet with high experience levels, leading to a decisive to-hit differential - equivalent to outmaneuvering an enemy, with whatever specific details that requires.
