AT4(AT-4)是瑞典紳寶波佛斯動力(Saab Bofors Dynamics)生產的一種單發式單兵反戰車武器,它取代了美國和北約武器庫內的M72 LAW火箭筒。紳寶集團在AT4的銷售上取得了頗為顯著的成功,使它成為世界上最為普遍的反戰車武器之一。該武器的設計是希望使步兵單位有能力去摧毀或癱瘓他們所遇到的裝甲部隊和防禦工事,不過它對於擊毀現代主力戰車不是很有效。AT4的發射筒和火箭彈在製造後會先行組裝好成為整套,發射筒用後即丟。AT4的名稱來自於彈頭口徑尺寸的英文讀音「Eighty-four」。 The AT4 is a Swedish 84 mm (3.31 in) unguided, man-portable, single-shot, disposable, recoilless smoothbore anti-tank weapon built by Saab Bofors Dynamics (previously Bofors Anti-Armour Systems and before that FFV Ordance).[unreliable source?] Saab has had considerable sales success with the AT4, making it one of the most common light anti-tank weapons in the world. The M136 AT4 is a variant used by the United States Army.The name AT4 is a word play on the 84 mm caliber of the weapon, (84) 'eighty four' being a homophone of 'A-T-4'. The name also doubles as an alpha-phonetic word play on the weapon's role due to "AT" being a common military abbreviation for "Anti-Tank".The name was created for export purposes as the nickname "eighty-four" already was a common English nickname for the Carl Gustaf 8.4cm recoilless rifle after its caliber.
The AT4 is
a single-shot individual anti-tank weapon produced by Swedish Saab Bofors Dynamics.
It replaces the M72 LAW rocket launcher in the US and NATO arsenals. It
is a recoilless weapon.
This represents the inertia of the projectile forward
and The energy of the propellant gas ejected from the rear of the barrel is
balanced
because the weapon
produces almost no recoil,
allowing the use of relatively larger shells that other man-portable weapons
cannot
.
Also
because the barrel does not need to withstand traditional guns
It can also be designed to be very light
. The disadvantage of this design is that
it
creates a large "backfire" area behind the weapon, which
can cause severe burns and pressure injuries to nearby allies and even the user. The
user must First, make sure that
there are no friendly troops or equipment in the rear flame area.
If you are squatting,
you must put your feet to the side to
avoid burning
yourself. It is very dangerous to launch an AT4 from a confined space
because it will rapidly increase the surrounding pressure.
If the breech is 15 kilometers There is a wall or other hardware behind the ruler within the ruler.
The problem of the "back flame" on the soldier
was solved by the AT4-CS introduced in the 1990s.
It is an AT4 subtype designed for urban warfare
so that the user can safely It
is fired from bunkers or buildings,
but the
attack effect of the AT4-CS version is poor due to the drop in muzzle velocity.
AT4-CS will discharge salt water to the rear when launching
to slow down the shock wave. The
muzzle velocity of the warhead drops from 290m/s to 220m/s,
but because of the molding The impact speed of the medicine
has nothing to do with the penetration depth. The
destructive power of the warhead is not reduced,
although the speed reduction will
have an adverse effect on aiming at moving targets.
However, AT4 is a short-range anti-tank weapon. The
warhead has a short flight distance and
has little impact.
Easier to use behind cover
Allows soldiers to fire
rockets from concealed positions
against enemy armored personnel carriers or combat vehicles without being exposed to enemy fire,
improving soldier safety
and the chance of a successful attack.
Before the AT4 was adopted in Sweden
it was Participated in the US Army's
new anti-tank weapon competition. The
final winner was the AT4
and the German crossbow bazooka.
Although the US Army was satisfied with the AT4, the
US Army still believed that its sights
and straps had room for improvement.
After the redesign, the
AT4 was adopted by the US military. And called it the
M136 Anti-Tank Grenade Launcher (LAW).
Saab's remarkable success in selling the AT4
made it one of the
most ubiquitous anti-tank weapons in the world. The
AT4 was designed to enable infantry Units
are capable of destroying or disabling
the armor and fortifications they come across
but it is
not very effective against modern main tanks.
A 130mm
tandem version of the AT4 was tested in the early 1990s.
This version works through any
modern The armor of the main tank,
but the plan was eventually cancelled due to the collapse of the Soviet Union
and the shrinking defense budget
