At present, there are two "Javelin" missiles in the world, namely the "Javelin" anti-tank missile of the US military and the "Javelin" anti-aircraft missile of the British army.
FGM-148 "Javelin" anti-tank missile is a kind of individual shoulder-fired anti-tank missile developed by the United States, mainly used to accurately destroy a variety of light and heavy armored targets, in the photo mode, javelin missiles can also mark specific terrain (buildings, bunkers, trenches, etc.), Javelin missiles can be loaded with a variety of warheads to achieve the maximum strike effect on different types of targets.
The "Javelin" basically retained the shape and overall layout of the "blowpipe", improved the launcher, and improved the firing conditions; Also improved solid rocket main engine; This increases the thrust, increases the flight speed and range; At the same time, the improved fuze can be remotely released. This allows the missile to avoid the wrong target when it is not detonated. However, the most important improvement is that the "Javelin" missile can be automatically guided, replacing the hand-controlled guide of the "blowpipe" missile, improving the shooting accuracy, and also shortening the training time of the shooter by two-thirds compared with the "blowpipe".
The Javelin has three different firing methods. The first is a three-legged bracket type, a triple launcher; The second is an armored vehicle-mounted quadruple launcher; The third is the helicopter air-to-air launcher, which is also under further consideration for the development of four new multi-mount launchers, namely a triple portable launcher with a triptych bracket and a Sagittarius seat; Triple portable launcher with triptych bracket: "Ranger" wheeled car loading type: armored vehicle loading type, etc.
Overview A soldier test-fired Javelin missile Javelin missile at a test firing site Is a pre-fire lock-in and post-fire disregard missile, this system uses a top attack flight mode for armored vehicles, attacking generally thinner top armor, but can also attack buildings or defensive positions in direct attack mode, and this missile can also be used to engage helicopters in direct attack mode. It can fly up to 150 meters when attacking at the top and 50 meters when attacking directly. The weapon system is equipped with an infrared imaging seeker and uses two tandem warheads with a tapered charge, the former detonating any explosive reactive armor, and the main warhead running through the base armor. Javelin missiles were used in the 2003 Iraq War and dealt devastating blows to Iraq's T-72 tanks and Type 69 tanks.
The missile ejects from the launcher for a safe distance from the operator and then ignites the rocket engine, making it more difficult to see the launcher and allowing the missile to be fired from inside a building, although the rear flame of the launcher can still cause damage to nearby personnel. Thanks to the post-launch system, the operation team can be immediately displaced after the missile launch, this launch method is called a soft launch system, which can be launched in the position or behind the cover, the traditional hard launch system can not achieve this launch method due to the large flame behind the barrel, and the former battlefield survival rate and ambush effect is far greater than the latter.
This weapon system is usually operated by a two-man team, a shooter and a bomb carrier, and when the shooter draws and fires the missile, the bomb carrier searches for the next target and is on the lookout for enemy threats such as vehicles and troops.
Double shooting team
This man-portable weapon system can easily break apart the main components and assemble them when needed, a clear difference compared to other cumbersome anti-tank weapon systems, for example, a tow missile requires a heavy tripod, a bulky thermal imaging camera protection box, a larger, longer launcher, and takes more time to assemble and prepare, and the Javelin missile (although also heavy) is lighter than other missiles and their necessary components.
While the CLU's thermal imagery may hinder aiming, its thermal imaging calibration system allows the javelin to be ignored after firing, which gives the launcher the opportunity to go unseen and perhaps move to a new firing angle, or leave the area before the enemy finds itself under attack, which is much safer than using a wireguide system, where the launcher must stop at the launch site and direct the missile to the target.
Another advantage is the impact capability of the Javelin, which uses a longitudinal conical charge warhead and is built against penetrating reactive armor, the Javelin is designed to penetrate any tank armor and was tested on the M1 Abrand tank, which can be easily destroyed using the top attack mode javelin because it can attack from the weakest points of most tanks.
The javelin's soft firing capability allows it to have a minimum rear flame area, which allows the javelin to be fired from a variety of buildings, which gives the javelin an advantage over the widely used AT4 in urban warfare, because the AT4 has a large rear flame area, and if the AT4 is fired from a small building, its large rear flame area will seriously damage the operator.
Folding disadvantages
One soldier took aim, and the other soldier prepared with a bullet
The main disadvantage of this weapon system is its weight of 22.5 kg, which is not included in the weight of the backup batteries (BA5590 lithium batteries), each weighing about one kilogram, according to the javelin manufacturer's assessment, a battery lasts about four hours, and the average number of batteries carried (not counting the "just in case" batteries that most squads will carry) is 5-10, depending on the length of the task This number may be more or less. The system was designed to be carried on foot by individuals, but weighed more than the army's original numbers, and the weight and normal combat load made the javelin squad the heaviest deployed basic infantry unit in the U.S. Army, and another comparable two-man infantry squad was the M240G machine gun team.
Another disadvantage is its dependence on the camera, which will not be available until the cooling part cools down the system, the manufacturer will have to wait about 30 seconds for the process to complete, but depending on the ambient temperature, it may take longer, and the camera is often hindered by the natural phenomenon of rapid heating and cooling of the surface, which may interfere with the identification and locking of the intended target.
The range of the Javelin is also negative, with the current maximum range of only about 2,500 meters, less than another mainstream anti-tank weapon towed missile (BGM-71 TOW), the larger towed BGM-71A can reach 3,000 meters, and other sub-types (BGM-71B to BGM-71F) can reach 3,750 meters.
