High explosive bombs of world war 2?

Answer 1

"Bouncing bomb" could refer to a number of things:

First, and probably what you are asking about, is the Vickers Type 464 bouncing bomb, which resembled a naval depth charge in its shape, carried by RAF bombers of the No. 617 squadron, and designed to destroy German dams by 'skipping' across the water of the man-made lakes the dams created (due to their cylindrical shape), colliding with the wall of the dam, and flooding the land around them once a breach in the dams' concrete could be created. This would deprive the German industry of the electrical power the dams created, as well as cause collateral damage by flooding any relevant economic assets the Germans possessed near the dams.

Later, the British improved upon the design by creating the "Highball:" a spherical bomb which was said to be even more effective at "dam-busting" owing to its unique shape. The bombs were very effective against the Germans in WWII, and resulted in widespread damage and heavy loss of life.

The other thing you could be referencing is the US's practice of "skip-bombing" against Japanese shipping in WWII. In Tameichi Hara's Japanese Destroyer Captain, Hara's ship is confronted by American bombers employing a new tactic against the IJN. The bombers (usually two-engined planes) would fly low and fast over the water, and release their bombs at flat trajectories. The shallow impact angle would mean the bombs, without time to arm, would "skip" off the surface of the water like stones, and, if timed right, crash into the enemy ship right at the waterline and cause tremendous damage. As it was, Hara's destroyer was able to avoid the bombs and shoot down the two attacking bombers, but he emphasizes the deadliness of the American tactics in attacks on other vessels, indicating substantial historical success.
