April 29, 1943 . The CAP consisted of more than 75,000 volunteers on April 29, 1943 when it was transferred to the War Department as an auxiliary of the AAF. On antisub patrol, CAP crews in ight planes ranged as far as 150 miles out to sea. During 18 months of antisub patrol  in 1942-3, CAP crews flew 244,600 hours, the equivalent of 24 million miles. They reported 173 enemy subs and summoned aid for 91 ships in distress and for 363 survivors of submarine attacks.

After some CAP planes began carrying bombs and depth charges, they attacked 57 subs, sinking or damaging at least two.Other subs were destroyed by AAF or Navy (see Navy Hand Book For Its Aviation Cadets) planes and ships called out by CAP pilots by radio. CAP efforts in WWII were not without sacrifice for during antisub patrol operations alone, they lost 90 airplanes and 26 members.
