Bombardier torpilleur

[adam]

Bonjour, je suis tout nouveau sur le forum.
Ce qui m'amène ici: j'aimerais savoir si les bombardiers torpilleurs de la 2nde guerre mondiale était capable de lancer leur torpille sur un sous-marin en immersion périscopique!

Merci de vos réponses et/ou liens correspondants.

Il y a au moins le Grumman TBF Avenger qui en était capable (sans doute d'autres avions aussi).

dont voici un extrait:

Service in the Atlantic Ocean
In the Atlantic, the Avenger was the obvious choice for use aboard British and American escort carriers in screening convoys and hunting down U-boats. Avengers would sight surfaced U-boats, and swoop down on them in a glide bombing approach, releasing multiple 250-pound, 325-pound, or (most often) 500-pound depth bombs. If the U-boat put up accurate flak, the Avenger pilot might choose to circle out of range wait for other aircraft to assist. Grumman Wildcat fighters, with either four or six heavy machine guns, were often effective at subduing the U-boat's flak battery so that the Avengers could more safely make their attacks. Later the Avenger's arsenal included rockets for use on surfaced U-boats and, after mid-1943, a super-secret anti-submarine homing torpedo known as the Mark 24 Fido (also called Zombie). Various versions of the Avenger were fitted with radar for finding submarines or surface ships, with sonobuoys to track submerged submarines, and with flares and searchlights for illuminating potential targets at night. Avengers were known to carry combinations of these devices, such as two 500-pound depth bombs, one Fido, radar, flares, and sonobuoys.

American escort carrier air groups sank, or assisted in sinking, 35 submarines in the Atlantic. Most, perhaps all, of these kills must have been made by Avengers. To this total must be added the achievements of British Avengers. Additionally, Avengers flew anti-submarine patrols from land bases, and laid mines.

In all, 9,839 Avengers were assembled, including 2,293 TBFs built by Grumman and 7,546 TBMs built by Eastern Aircraft (General Motors). After the war, they faded from service more gradually than most aircraft of the era, serving useful roles into mid-1950s.

35 U-boats lost to Avenger aircraft. + means that the Avenger shared the credit for the sinking.

Merci Luc, mais à ce que j'ai compris (je ne suis pas très doué en anglais) les U-Boot ont été coulé avec des bombes plus ou moins grosse (comme les grenades ASM des destroyers) et non avec des torpilles?

"Avengers would sight surfaced U-boats, and swoop down on them in aglide bombing approach, releasing multiple 250-pound, 325-pound, or(most often) 500-pound depth bombs"

Où j'ai mal traduit?

U-43

Sunk 30 July, 1943 south-west of the Azores, in position 34.57N, 35.11W, by a Fido homing torpedo from an Avenger aircraft of the US escort carrier USS Santee 55 dead (all hands lost).

U-117

About 20 minutes later two more Avengers and two Wildcats arrived from the carrier and forced U-117 to dive by strafing and attacks with depth charges. The boat was apparently hit and sunk by one of two Fido torpedoes dropped by the Avengers around 12.45 hours. (Sources: Franks/Zimmerman)

U-509

Sunk 15 July, 1943 in the mid-Atlantic north-west of Madeira, Portugal, in position 34.02N, 26.01W, by aerial (Fido) torpedoes from "Avenger" aircraft (VC-29) of the US escort carrier USS Santee. 54 dead (all hands lost).

Number of submarines sunk by FIDO : 31

Merci beaucoup Luc pour ce second lien, très intéressant.
Ceci m'amène à d'autres questions:

1-Les Alliés ont-ils eu accès à la technolgie de torpille acoustique?

2-Les bombardiers classiques étaient-ils plus efficaces que les bombardiers torpilleurs contre les sous-marins?

Et une petite dernière^^:

3-A partir de quelle profondeur un U-Boot était-il à l'abris d'un raid aérien par torpille et par bombardement?

Adam, tu as tout compris. Tu es sur le plus convaincu des sites militaires. Moi-même en ULM ne décolle le petit doigt de la couture du pantalon que pour laisser mon pouce atteindre sur le manche le bouton des armes de bord.
Occupe-toi d'Eve...
En date du 7 juillet, rubrique "le bar", tu trouveras un récit qui devrait te plaire, un inédit d'assaut sur Hanoï en F-105.

1-Les Alliés ont-ils eu accès à la technolgie de torpille acoustique?

Même si tu n'es pas "très doué en anglais", je suppose que tu as lu et compris le titre de l'article dont j'ai posté le lien :

Torpedo MK 24 - "FIDO
The First American ASW Acoustic Homing Torpedo

first = premier
american = américain
ASW = anti-submarine warfare = guerre anti-sous-marine
acoustic = acoustique
homing = pointage
torpedo = torpille


Pour le reste, Jean-Pierre a raison ; tu ferais mieux d'aller sur un forum de passionnés d'armement si tu veux approfondir tes questions dans ce domaine.
