Pre-war USAAF doctrine envisioned three classes of aircraft. Attack aircraft used in direct support of the ground troops classed A- for attack, heavy bombers for attacking strategic targets, and medium bombers for those "in between" targets. By the latter part of the war, with the introduction of the B-29 and the A-26, the medium bomber concept had fallen out of favor. The A-26 could carry as many as, or more bombs than, the B-25 and B-26, and the Army was seriously considering reclassifying the B-17 and B-24 as "medium".
