MAD Retro-Bombing - WWII Anti-Submarine Combat Results

Ғылым және технология

WWII German U-Boats generally submerged when spotting allied aircraft. Once submerged, they were basically invisible and invulnerable to depth bombing. The allied anti-submarine command developed both aircraft sensors to find and track submerged U-boats and kill stores to sink submerged U-boats. One of the most unique combination of aircraft deployed sensor and kill store was the MAD sensor working with the retro-rocket-bomb. This combination of sensor and kill store was adopted by the PBY from VP-63. This video will unpack the combat effectiveness of this combination in the sinking German of U-boats in WWII. While in development, the MAD retro-rocket bomb was predicted to be the “number one anti-submarine weapon”.

    @@roberthutchins1507 That damn tape recorder was heavy. I used to carry it myself and pissed the airframes guys off when I broke a few steps. They were good times. In 1973 I went on Unitas 14. That was a busy year, I also did 4 months in Sigonella with a few side trips to Souda Bay and Rota. I was a ground pounder that went about everywhere they needed to bring one from the AT shop. Got to go on some patrols and I remember one where we left smokes on the water from the mad. My older brother was loading the big magnesium flares on a P-2. This was done standing on a flatbed truck. They all started shooting him at once and put him in the hospital for 10 months. I remember they called my parents and said if you want to see you son alive you better get here fast. We lived in eastern Ct. and my dad hauled ass, got stopped once and the cops radioed ahead to let him fly in his big Ford wagon with the 428. One of the flight engineers in our squadron was a 2nd Mech in my brother’s squadron then and saw my brother stumble out of the white smoke. We both came to Alaska over 40 years ago.

    Japan had a decent late-war MAD set-up where the aircraft automatically released dye and smoke markers when the return signal reached it's strongest, so theoretically when it was directly over the target sub. They could also have it deploy depth bombs in unison with the markers.

    Quite interesting! It is not al that surprising that this did not work all that well in that the aircraft had to get really close for it top detect a submarine and thus the chances of a direct overflight are pretty low.

    It's only needed for the final kill. You find the submarine by picking up either its sail or its snorkel on the radar, and if it sees you too soon and dives, you use this to kill it.

    I'm not sure you could reverse a WWII Kreigsmarine sub on diesel power. Only two ways of doing it would be A) a gearbox having reverse. B) Many marine diesels could be shut off and restarted in reverse. Never heard of either of those features in those subs. If I was the designer - no more than astern power is needed - I would just use the giant DC electric motors for that.

    No some aircraft use it. Initially it used the detector from German magnetic mines accidentally dropped in areas accessible at low tide. Someone thought of using them in reverse. Apparently a huge problem was the number of sunken ships in the sea near Gibraltar. Attacks would only be attempted if it was proved the target was moving. That's why the markers were used. They showed if the target was actually moving.

    MAD is a non deployable sensor in much the same way as radar is. You can think of it as a free gimbaled gyro, that remains oriented to the earth's natural magnetic field. Large metal objects cause a slight disruption in that field, causing the gimbaled sensor to move slightly, and displays that disruption in the magnetic field to the operator.
