I want to know the answer to the following question:
How many Japanese ships were sunk in 1944 by United States submarines?
All the background I'm provided with is that "The number of U.S. submarines patrols (and sinkings) rose steeply: 350 patrols (180 ships sunk) in 1942, 350 (335) in 1943, and 520 (603) in 1944.". Is that enough to answer the question?
Answer: yes
