Did the U.S. Navy contribute effectively to World War I ASW?

Did the U.S. Navy make a significant anti-submarine contribution in World War I?

Yes; the U.S. Navy performed strong anti-submarine work even while its arriving battleship squadron needed more gunnery practice.

The U.S. Navy is credited with very good anti-submarine warfare during World War I. The Royal Navy valued that contribution, even though it also welcomed American battleships and sent their crews for additional gunnery practice. The two judgments concern different capabilities and should not be collapsed into one verdict on the service. Coalition warfare could use American strengths while correcting a separate training shortfall.
