On the second day, U.S. reconnaissance planes located Ozawa's fleet, 275 miles (443 km)[citation needed] away, and submarines sank two Japanese carriers. Mitscher launched 230 torpedo planes and dive bombers. He then discovered the enemy was actually another 60 miles (97 km)[citation needed] further off, out of aircraft range (based on a roundtrip flight). Mitscher decided this chance to destroy the Japanese fleet was worth the risk of aircraft losses due to running out of fuel on the return flight. Overall, the U.S. lost 130 planes and 76 aircrew; however, Japan lost 450 planes, three carriers, and 445 aircrew. The Imperial Japanese Navy's carrier force was effectively destroyed.
