Construction 129 was never completed or used despite its imposing appearance. It was intended to be armed with two guns with massive sixteen-inch-diameter barrels. Each weapon weighed almost one million pounds and could accurately fire a two thousand one hundred pound shell twenty-seven miles. The fortification was to have been the highest artillery battery in the Bay Area. Work stopped in the mid-1940s, shortly after its guns arrived for mounting, because the army found that weapons like those there and in similar batteries would not be effective against attack by enemy planes. The fortification was then abandoned, and it was never officially named or manned.
