Divebomber

A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional "level" bombers, even en-masse.

A dive bomber dives at a steep angle, normally between 45 and 60 degrees or even up to a near vertical dive of 80 degrees with Ju-87, and thus requires an abrupt pull-up after dropping its bombs. This puts great strains on both pilot and aircraft. It demands an aircraft of strong construction, with some means to slow its dive. This limited the class to light bomber designs with ordnance loads in the range of 1,000 lb (450 kg) although there were larger examples. The most famous examples are the Junkers Ju 87 Stuka, which was widely used during the opening stages of World War II, the Aichi D3A "Val" dive bomber, which sank more Allied warships during the war than any other Axis aircraft, and the Douglas SBD Dauntless, which sank more Japanese shipping than any other allied aircraft type. The SBD Dauntless helped win the Battle of Midway, was instrumental in the victory at the Battle of the Coral Sea, and fought in every US battle involving carrier aircraft.

An alternate technique, glide-bombing, allowed the use of heavier aircraft, which faced far greater difficulties in recovering from near-vertical approaches and allowed greater use of sophisticated bombsights and aiming techniques, by a specialised member of aircrews, namely a bombardier/bomb aimer. The crews of multi-engined dive-bombers, such as variants of the Junkers Ju 88 and Petlyakov Pe-2, frequently used this technique. The heaviest aircraft to have dive-bombing included in its design and development, the four-engined Heinkel He 177, also utilised a glide-bombing approach; the requirement that the He 177 be able to dive/glide-bomb delayed its development and impaired its overall performance.
