Air Attacks on U-boats | Royal Navy Instructional Film (1941) 

Must have been an atomic one.

What a Richard Cranium - It was a low flying Banana!

1st May1943 was when the Stay up and fight order was issued to the U-boats. It was rescinded 3 months later. Between Sep 39 and Jun 41, Coastal Command lost 90 aircraft doing Anti U Boat Patrols and Convoy Escorts. The total number of U-boat sunk by aircraft by the end of 1941 was 6 (1 by Bomber Command, 3 by the Fleet Air Arm and (2 sharded with warships) 2 by Coastal Command (shared)).

@@richardvernon317 Thanks for crossing the T's and dotting the I's . 41/42 I believe that Coastal Command concentrated on the Bay of Biscay area mainly because it was within range of its aircraft , it was also within range of German fighters like the Ju88's .

@@jameswebb4593 Just flying over the sea back then was dangerous!!! The aircraft only became a serious killer of U-boats in 1943, it was then that all of the technology required for it to do the task effectively was perfected. It was not just the search radar, suitable radar altimeters were not available, or low depth Hydrostatic fuzes, or long range navigation systems like LORAN or Sonobuoys or Homing Torpedoes or Rockets. All of that stuff became available in the first 6 months of 1943.

@@jameswebb4593 Got two air to air kills with a Hudson as well!!! There is a reason 120 Squadron got their standard early.

I dare you to say that in person to me or one of my other Submariner colleagues. But check your health insurance status first!

Theres a channel that put up a sound recording of a Japanese sub that was sunk in the Atlantic by an American airborne sub patrol. The sub was on a mission to Germany probably delivering rubber ingots in return for whatever stuff they needed. Pretty desperate and pointless voyages half way around the planet. Most of the subs were sunk. They would drop acoustic microphones to listen for out for the sub and ascertain if the attack was successful. You can hear the pilot telling one of the crew to shut up as he's listening out for the main explosion to happen. The depth charge attack was successful and you hear crackling and popping of the subs hull a it drops through the water column. It goes on for several minutes.

@@richardvernon317 that's it in one. Good channel.

just patrolling some area denies freedom of movement for sub...even if nothing happens

As the sub would be trimmed down forward to assist in getting the uboat under the surface as quickly as possible, to order both motors full astern would simply pull the stern of the Uboat to the surface again. The idea of superfast jinking about to evade attack sounds ideal, but remember even at full speed underwater the uboat was moving at the pace of a moderate jog, and going full astern would require maybe 10 or 15 seconds to allow the propellers to stop turning then another 10-15 seconds for them to start turning in reverse which would leave the submarine stationary for 20-30 seconds barely under the surface.
