Missed a head-on collision with a large drone by an estimated 100 [feet] or less. The drone was still visible in the top of my windscreen as we passed underneath. It was completely centerline to our aircraft just slightly above our glide path to RWY 27 into SAN. When I made the report we were on path inside a mile prior to CIJHI I believe.  The drone was very large and shaped like a large garage door motor or a plastic shell that you keep luggage in on top of your car.  It was a shiny; metallic red color with a chrome sheen similar to how colleges are painting their alternate football helmets.  Could not clearly identify any rotors; just the shape and color. It was not a small recreational drone; it appeared to be the size of a YETI cooler and we just missed hitting it dead on...not a few feet to the right or left; but dead center. We were asked the drone's direction of flight and responded west to east (towards us) but honestly it seemed to be stationary and was probably videoing planes arriving into SAN. The flight landed uneventfully. No damage was observed to our aircraft post-fight.
