It just now struck me that neither the Enterprise nor the Constellation fire any photon torpedoes at the Doomsday Machine, at least not on-camera.
Obviously, that's because in an already effects-heavy episode adding the challenge of photon torpedo animation (at least hitting the thing) would be one more unbearable burden, especially when they'd serve the same plot function as phasers: bouncing uselessly off the planet-killer's hull.
But is there a workable fan explanation for why photon torpedoes are apparently so unsuitable to the action that nobody even suggests lobbing one at the thing?
