Armes Antichar Américaines

Types de Projectiles et leur Capacité de Pénétration de Blindage

Semi-chenillé M3 avec mitrailleuse .50 cal. Browning

The table lists armour penetration values des armes et canons antichar américains at 0 to 100 meters range et 0 degrees inclination of armour. Dates indicate the year when a particular shell type entered production, not necessarily the year of availability to combat units. New shell types would take several months to reach the troops at the front, some favoured units receiving the new shells more quickly than others. Andrew Mark Reid is the author of Panzergranate, a set of miniature wargame rules using carefully researched gunnery data to simulate armour penetration results.

Mitrailleuses

Mitrailleuse Projectile Pénétration
7.62 mm (0.30 Inch) M.2 & M.3. Browning L.M.G. "K" Bullet 12 mm
12.7 mm L.130.2 (0.50 Inch) Browning H.M.G. A.P. 25 mm
12.7 mm L.130.2 (0.50 Inch) Browning H.M.G. A.P./I. (Incendiary) 22 mm

Grenades à Charge Creuse

Arme Projectile Pénétration
M9 Rifle Grenade (U.S.) H.E.A.T. (Munroe) 100 mm
La grenade à fusil M9 américain had a range of 10 metres, et a blast radius -- mainly directly towards the firer -- of 12 metres. The weapon was not safe to be fired from the open ou from poor cover.
50 mm Bazooka (U.S.) H.E.A.T. (Munroe) 119 mm
Bazooka, et Panzerschreck rocket projectors are missile weapons which produce a less dangerous backblast que le Panzerfaust de sans recul, although the backblast is still noticeable enough to reveal the firing position. Rocket projectors can be fired from enclosed spaces avec minimal risk to the operator, et there is enough historic evidence to suggest that this was done in combat. The Panzerschreck fired a larger warhead than the Bazooka, et the weapon had a face shield to protect the operator.

Canons de Chars et Antichars

Arme Projectile Pénétration
37 mm L.21 (Christie T.3, etc.) A.P. 31 mm
37 mm L.53. M.3 A.P.C. 76 mm
37 mm L.53. M.3 avec Little John A.P.S.V. (1943) 97 mm
Le Little John squeeze bore attachment britannique was originally designed to increase the velocity et armour penetration of the 2 Pdr gun. Little Johns were tested on autres canons as well, but they became obsolete quand les canons antichar QF 6 pounder et 17 pounder entered service. Le char aéroporté Locust américain used the Little John attachment to extend the useful life of its already obsolete 37 mm gun. Des chars Locust were deployed in the Rhine crossings et before.
40 mm L.70. M.6. Flak (Bofors copy) A.P. 117 mm
57 mm L.23. (Canon de Char de la PGM) A.P.H.E. (1918) 32 mm
75 mm L.31. M.2 (Lee) & M.6 (Chaffee) A.P.C. (M.61) 76 mm
75 mm L.31. M.2 (Lee) & M.6 (Chaffee) A.P. (M.72) 89 mm
75 mm L.31. M.2 (Lee) & M.6 (Chaffee) A.P.C.B.C. (Late 1944) 96 mm
75 mm L.41. M.2 & M.3 (Sherman) A.P.C. (M.61) 101 mm
75 mm L.41. M.2 & M.3 (Sherman) A.P. (M.72) 118 mm
75 mm L.41. M.2 & M.3 (Sherman) A.P.C.B.C. (Late 1944) 127 mm
76 mm L.52. M.6 Canon de Char & Antichar A.P.C. (M.61) 127 mm
Prior to the Normandy invasion, the U.S. Army Ordinance Department had promised that the new 76 mm L.52. M.6 gun would take out any blindé en service allemand. This turned out not to be the case, the gun performed poorly against chars Tiger I et Panther, et it was incapable of penetrating the frontal armour of the Königstiger. A request for chars Sherman Firefly avec the more powerful 17 pdr gun was turned down par l'Ordinance Department britannique. Instead, American units were hastily re-equipped avec A.P. (M.79) shells, but much of the A.P.C. (M.61) ammunition remained in service until the end of the war.
76 mm L.52. M.6 Canon de Char & Antichar A.P. (M.79) 155 mm
76 mm L.52. M.6 Canon de Char & Antichar A.P.C.B.C. (M.93) 208 mm
90 mm L.52 Canon de Char & Antichar A.P. (T.33) 148 mm
90 mm L.52 Canon de Char & Antichar A.P.C. (M.82) 163 mm
90 mm L.52 Canon de Char & Antichar A.P.C.B.C. (M.304) 270 mm
105 mm L.23 Howitzer M2 H.E.A.T. 102 mm
The 105 mm howitzer was mounted on the M7 Priest, et the Sherman Jumbo assault tank variant. The weapon fired H.E.A.T. shells designed to penetrate concrete. Available range test data indicates that the shell penetrated 4 Inches (102 mm) of armour at any range.
155 mm L.46 Howitzer A.P. (M.112) 168 mm

American shells performed poorly against chars allemands, particularly against the heavily armoured Panthers, Tigers et Königstigers. Many efforts were made to remedy the situation, but the older, less effective ammunition continued to be issued even as supplies of improved shells became available. It was not uncommon for véhicules to carry all the different types of shells in their racks at the same time. Unable to rely on just one type of A.P. shell to engage any potential ground target successfully, équipages de chars américains had to deal avec the additional stress of selecting the proper shell for the job at hand.
