The firing team may move as soon as the "fire-and-forget" missile has been launched, or immediately prepare to fire on their next target. The missile system is sometimes carried by two soldiers consisting of a gunner and an ammunition bearer, although one soldier can fire it. While the gunner aims and fires the missile, the ammunition bearer scans for prospective targets, watches for threats like enemy vehicles or troops and ensures that personnel and obstacles are clear of the missile's launch backblast.


Development

In 1983, the

Test and evaluation

Development test and evaluation is conducted to demonstrate the engineering design and development process is complete. It is used to reduce risk, validate, and qualify the design. It also ensures that the product is ready for government acceptance. The DT&E results are evaluated to ensure that design risks have been minimized and the system will meet specifications. Results are also used to estimate the system's military readiness when it is introduced into service. DT&E serves a critical purpose as it reduces the risks of hazards by testing selected high-risk components or subsystems. DT&E is the government developing agency tool used to confirm that the system performs as specified and that the system is ready for field testing. DT&E is an iterative process of designing, building, testing, identifying deficiencies, fixing, retesting, and repeating. It is performed in the factory, laboratory, and on the proving ground by the contractors and the government. Contractor and government testing is combined into one integrated test program and conducted to determine if the performance requirements have been met and to provide data to the decision authority. The General Accounting Office (GAO), since renamed

, published a report questioning the adequacy of Javelin testing. The report, titled "Army Acquisition—Javelin Is Not Ready for Multiyear Procurement", opposed entering into full-rate production in 1997 and expressed the need for further operational testing due to the many redesigns undergone. In 1995, Secretary of Defense William Perry had set forth five new operational test initiatives. These included: 1) getting operational testers involved early in development; 2) use of modeling and simulation; 3) integrating development and operational testing; 4) combining testing and training; and 5) applying concepts to demos and acquisitions. The late-phase development of the Javelin retroactively benefited from the then new operational test initiatives set forth by the Secretary of Defense, as well as a further test conducted as a consequence of the Army's response to the GAO report. Before the Milestone III decision, and before fielding to 3rd Battalion, 75th Ranger Regiment at Fort Benning (also Army Rangers, Special Forces, airborne, air assault, and light infantry), the Javelin was subjected to limited parts of the five operational test and evaluation initiatives, as well as a portability operational test program (an additional test phase of the so-called Product Verification Test), which included live firings with the full-rate configuration weapon. Per initiatives and as a DT&E function, the

(IDA) and the Defense Department's Director of Operational Test and Evaluation (DOT&E) became involved in three development test activities, including: 1) reviewing initial operational test and evaluation plans; 2) monitoring initial operational test and evaluation; and 3) structuring follow-on test and evaluation activities. The results of these efforts detected problems (training included) and corrected significant problems which led to modified test plans, savings in test costs, and GAO satisfaction.


Qualification testing

The Javelin Environmental Test System (JETS) is a mobile test set for Javelin All-Up-Round (AUR) and the Command Launch Unit (CLU). It can be configured to functionally test the AUR or the CLU individually or both units in a mated tactical mode. This mobile unit may be repositioned at the various environmental testing facilities. The mobile system is used for all phases of Javelin qualification testing. There is also a non-mobile JETS used for stand-alone CLU testing. This system is equipped with an environmental chamber and is primarily used for Product Verification Testing (PRVT). Capabilities include: Javelin CLU testing; Javelin AUR testing; Javelin Mated Mode testing; Javelin testing in various environmental conditions; and CLU PRVT. The all-up-round test sets include: extreme temperature testing; missile tracker testing (track rate error, tracking sensitivity); seeker/ focal plane array testing (cool-down time, dead/defective pixels, seeker identification); pneumatic leakage; continuity measurements; ready time; and guidance sections (guidance commands, fin movement).


Components

The system consists of three main components: the Command Launch Unit, the Launch Tube Assembly and the missile itself.


Command Launch Unit

The gunner carries a reusable Command Launch Unit, more commonly referred to as a CLU (pronounced "clue"), which is the targeting component of the two-part system. The CLU has three views which are used to find, target, and fire the missile and may also be used separately from the missile as a portable thermal sight.

s with thermal sights. This makes infantry personnel more flexible and able to perceive threats they would not otherwise be able to detect. In 2006, a contract was awarded to Toyon Research Corporation to begin development of an upgrade to the CLU enabling the transmission of target image and GPS location data to other units.

The first view is a 4× magnification day view. It is mainly used to scan areas in visible light during daylight operation. It is also used to scan following sunrise and sunset, when the thermal image is hard to focus due to the natural rapid heating and/or cooling of the

WFOV (wide field of view)

The second view is the 4× magnification night view, and shows the gunner a thermal representation of the area viewed. This is also the primary view used due to its ability to detect

unit attached to the sight. This greatly increases the sensitivity of the thermal imaging capability since the temperature inside the sight is much lower than that of the objects it detects. Due to the sensitivity this causes, the gunner is able to "focus" the CLU to show a detailed image of the area being viewed by showing temperature differences of only a few degrees. The gunner operates this view with the use of two hand stations similar to the control stick found in modern cockpits. It is from this view that the gunner focuses the image and determines the area that gives the best heat signature on which to lock the missile.


NFOV (narrow field of view)

The third field of view is a 12× thermal sight used to better identify the target vehicle. Once the CLU has been focused in WFOV, the gunner may switch to NFOV for target recognition before activating Seeker FOV. Once the best target area is chosen, the gunner presses one of the two triggers and is automatically switched to the fourth view; the Seeker FOV, which is a 9x magnification thermal view. This process is similar to the automatic zoom feature on most modern cameras. This view is also available along with the previously mentioned views, all of which may be accessed with the press of a button. However, it is not as popular as a high magnification view takes longer to scan a wide area. This view allows the gunner to further aim the missile and set the guidance system housed inside it. It is when in this view that information is passed from the CLU, through the connection electronics of the Launch Tube Assembly, and into the missile's guidance system. If the gunner decides not to fire the missile immediately, they can cycle back to the other views without firing. When the gunner is satisfied with the target picture, they pull the second trigger and establish a "lock". The missile launches after a short delay.


Lightweight CLU

The US Army developed a new CLU as an improvement over the Block I version. The new CLU is 70 percent smaller, 40 percent lighter, and has a 50 percent battery life increase. Features of the lightweight CLU are: a long-wave

Launch Tube Assembly

Both the gunner and the ammunition bearer carry the Launch Tube Assembly, a disposable tube that houses the missile and protects the missile from harsh environments. The tube has built-in electronics and a locking hinge system that makes attachment and detachment of the missile to and from the Command Launch Unit a quick and simple process.


Missile


Warhead

The Javelin missile's tandem warhead is a

to create a stream of superplastically deformed metal formed from trumpet-shaped metallic liners. The result is a narrow high velocity particle stream that can penetrate armor. The Javelin counters the advent of explosive reactive armor (ERA). ERA boxes or tiles lying over a vehicle's main armor explode when struck by a warhead. This explosion does not harm the vehicle's main armor, but causes steel panels to fly across the path of a HEAT round's narrow particle stream, disrupting its focus and leaving it unable to cut through the main armor. The Javelin uses two shaped-charge warheads in tandem. The weak, smaller diameter HEAT precursor charge detonates the ERA, clearing the way for the much larger diameter HEAT warhead, which then penetrates the target's primary armor. A two-layered

blast shield and the first that had a hole through the middle to provide a jet that is less diffuse. A newer main charge liner produces a higher velocity jet. While making the warhead smaller, this change makes it more effective, leaving more room for propellant for the main rocket motor, and thus increasing the missile's range. Electronic arming and fusing, called Electronic Safe Arming and Fire (ESAF), is present on the Javelin. The ESAF system enables the firing and arming process to proceed, while imposing a series of safety checks on the missile. ESAF cues the launch motor after the trigger is pulled. When the missile reaches a key acceleration point (indicating that it has cleared the launch tube), the ESAF initiates a second arming signal to fire the flight motor. After another check on missile conditions (target lock check), ESAF initiates final arming to enable the warheads for detonation upon target impact. When the missile strikes the target, ESAF enables the tandem warhead function (provide appropriate time between the detonation of the precursor charge and the

of the main charge). Though the Javelin's tandem HEAT warhead has proven efficient at destroying tanks, most threats it was employed against in Iraq and Afghanistan were weapon crews and teams, buildings, and lightly armored and unarmored vehicles. To make the Javelin more useful in these scenarios, the

developed a multi-purpose warhead (MPWH) for the FGM-148F. While it is still lethal against tanks, the new warhead has a naturally fragmenting steel warhead case that doubles the effectiveness against personnel due to enhanced fragmentation. The MPWH does not add weight or cost and has a lighter composite missile mid-body to enable drop-in replacement to existing Javelin tubes. The Javelin F-model was planned to begin deliveries in early 2020; the improved missile design, along with new lighter CLU with an improved target tracker, entered production in May 2020.


Propulsion

Most rocket launchers require a large clear area behind the gunner to prevent injury from backblast. To address this shortcoming without increasing recoil to an unacceptable level, the Javelin system uses a soft launch mechanism. A small launch motor using conventional rocket
propellant A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or other motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the ...
ejects the missile from the launcher, but stops burning before the missile clears the tube. The flight motor is ignited after a delay to allow sufficient clearance from the operator. To save weight, the two motors are integrated with a burst disc between them. It is designed to tolerate the pressure of the launch motor from one side, but to easily rupture from the other when the flight motor ignites. The motors use a common nozzle, with the flight motor's exhaust flowing through the expended launch motor. Because the launch motor casing remains in place, an unusual annular (ring-shaped) igniter is used to start it. A normal igniter would be blown out of the back of the missile when the flight motor ignited and could injure the operator. Since the launch motor uses a standard NATO propellant, the presence of lead beta-resorcylate as a burn rate modifier causes an amount of lead and lead oxide to be present in the exhaust; gunners are asked to hold their breath after firing for their safety. In the event that the launch motor malfunctions and the launch tube is overpressurized—for example, if the rocket gets stuck—the Javelin missile includes a pressure release system to prevent the launcher from exploding. The launch motor is held in place by a set of shear pins, which fracture if the pressure rises too high, and allow the motor to be pushed out of the back of the tube.


Seeker

missile, after launch the missile has to be able to track and destroy its target without assistance from the gunner. This is done by coupling an onboard imaging IR system (separate from CLU imaging system) with an onboard tracking system. The gunner uses the CLU's IR system to find and identify the target, then switches to the missile's independent IR system to set a track box around the target and establish a lock. The gunner places brackets around the image for locking. The seeker stays focused on the target's image, continuing to track it as the target moves or the missile's flight path alters, or attack angles change. The seeker consists of three main components: focal plane array image sensor, cooling and calibration, and stabilization.


Focal plane array (FPA)

The seeker assembly is encased in a dome that is transparent to long-wave
infrared Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of Light, visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from ...
radiation. The IR radiation passes through the dome and then through lenses that focus the energy. The IR energy is reflected by mirrors on to the FPA. The seeker is a two-dimensional staring FPA of 64×64 MerCad (HgCdTe) detector elements. The FPA processes the signals from the detectors and relays a signal to the missile's tracker. The staring array is a photo-voltaic device where the incident photons stimulate electrons and are stored, pixel by pixel, in

s attached at the rear of the detector. These electrons are converted to voltages that are multiplexed out of the ROIC on a frame-by-frame basis.


Cooling/calibration

To function effectively, the FPA must be cooled and calibrated. In other applications, a CLU's IR detectors are cooled using a
Dewar flask A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewa ...

, but there is insufficient space in the missile for a similar solution. Prior to launch, a cooler mounted on the outside of the launch tube activates the electrical systems in the missile and supplies cold gas from a Joule-Thomson expander to the missile detector assembly while the missile is still in the launch tube. When the missile is fired, this external connection is broken and coolant gas is supplied internally by an onboard

gas bottle. The gas is held in a small bottle at high pressure and contains enough coolant for the duration of the flight of approximately 19 seconds. The seeker is calibrated using a chopper wheel. This device is a fan of six blades: five black blades with low IR emissivity and one semi-reflective blade. These blades spin in front of the seeker optics in a synchronized fashion such that the FPA is continually provided with points of reference in addition to viewing the scene. These reference points allow the FPA to reduce noise introduced by response variations in the detector elements.


Stabilization

The platform on which the seeker is mounted must be stabilized with respect to the motion of the missile body and the seeker must be moved to stay aligned with the target. The stabilization system must cope with rapid acceleration, up/down and lateral movements. This is done by a gimbal system,

. Information from the gyros is fed to the guidance electronics which drive a torque motor attached to the seeker platform to keep the seeker aligned with the target. The wires that connect the seeker with the rest of the missile are carefully designed to avoid inducing motion or drag on the seeker platform.


Tracker

The tracker is key to guidance/control for an eventual hit. The signals from each of the 4,096 detector elements (64×64 pixel array) in the seeker are passed to the FPA

s which reads then creates a video frame that is sent to the tracker system for processing. By comparing the individual frames, the tracker determines the need to correct so as to keep the missile on target. The tracker must be able to determine which portion of the image represents the target. The target is initially defined by the gunner, who places a configurable frame around it. The tracker then uses
algorithms In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing ...
to compare that region of the frame based on image, geometric, and movement data to the new image frames being sent from the seeker, similar to

algorithms. At the end of each frame, the reference is updated. The tracker is able to keep track of the target even though the seeker's point of view can change radically in the course of flight. The missile is equipped with four movable tail fins and eight fixed wings at mid-body. To guide the missile, the tracker locates the target in the current frame and compares this position with the aim point. If this position is off center, the tracker computes a correction and passes it to the

. There are three stages in the flight managed by the tracker: 1) an initial phase just after launch; 2) a mid-flight phase that lasts for most of the flight; and 3) a terminal phase in which the tracker selects the most effective point of impact. With guidance algorithms, the autopilot uses data from the seeker and tracker to determine when to transition the missile from one phase of flight to another. Depending on whether the missile is in top attack or direct attack mode, the profile of the flight can change significantly. The top attack mode requires the missile to climb sharply after launch and cruise at high altitude then dive on the top of the target (curveball). In direct attack mode (fastball), the missile cruises at a lower altitude directly at the target. The exact flight path which takes into account the range to the target is calculated by the guidance unit.


Training

, for two weeks. The soldiers are taught basic care and maintenance, operation and abilities, assembly and disassembly, and the positions it can be fired from. Soldiers are also taught to distinguish between a variety of vehicle types even when only a rough outline is visible. The soldiers must accomplish several timed drills with set standards before being qualified to operate the system in both training and wartime situations. There are also smaller training programs set up on most army bases that instruct soldiers on the proper use of the system. At these courses, the training program might be changed in small ways. This is most commonly only minor requirements left out due to budget, the number of soldiers vs. simulation equipment, and available time and resources. Both types of training courses have required proficiency levels that must be met before the soldier can operate the system in training exercises or wartime missions.

(COIN) operations. Initially, soldiers perceived the weapon as unsuitable for COIN due to its destructive power, but trained gunners were able to make precision shots against enemy positions with little collateral damage. The Javelin filled a niche in US weapons systems against DShK heavy machine guns and B-10 recoilless rifles—weapons like the AT4 and the M203 grenade launcher were powerful enough, but the ~300m range was insufficient. Conversely, while medium and heavy machine guns and automatic grenade launchers had the range, they lacked the power; and heavy mortars, which had both a good range and more than enough power, were not accurate enough. The Javelin had enough range, power, and accuracy for dismounted infantry to counter standoff engagement tactics employed by enemy weapons. With good locks, the missile is most effective against vehicles, caves, fortified positions, and individual personnel. If enemy forces were inside a cave, a Javelin fired into the mouth of the cave would destroy it from the inside, which was not possible from the outside using heavy mortars. The psychological effect of the sound of a Javelin firing sometimes caused insurgents to disengage and flee their position. Even when not firing, the Javelin's CLU was commonly used as a man-portable surveillance system. During the al-Shaddadi offensive of the Syrian Civil War in February 2016, a Javelin was used to blow up an attacking suicide

holding a Javelin launcher in the style of an Eastern Orthodox church painting, gained attraction in social media and soon became a symbol of the Ukrainian resistance against the Russian invasion. An unknown number of Javelin launch tube assemblies were captured by the Russian armed forces during the conflict; it is unclear if any of the captured launchers contained live rounds, or were simply tubes discarded after being used. On 18 March, the Pentagon claimed out of 112 Javelins fired by the Ukrainians since the start of the war, 100 missiles had hit their target..Some of these missiles were captured by Russia during this war. In a commentary from the Center for Strategic and International Studies (CSIS), concerns were raised over the US stock of Javelin missiles. According to CSIS, the US has used close to one-third of its Javelin missiles; 7,000 have been supplied thus far, with the United States buying Javelins at the rate of about 1,000 a year. The maximum production rate is 6,480 a year, but it would likely take a year or more to reach that level. Orders take 32 months to deliver; the report concluded that it would take about three or four years to replace the missiles that have already been sent to Ukraine. The missile production rate could be increased greatly with a national procurement effort. On May 8, 2022, Lockheed Martin CEO James Taiclet stated that Lockheed will nearly double the production of Javelins to 4,000 a year. Additionally, Ukrainian officials estimated that up to 500 missiles per day were being used in the early days of the war. On August 8, 2022, the US committed to sending an additional 1000 Javelin missiles.

* : In 2010 India considered purchasing some systems off-the-shelf with a larger number to be license manufactured locally through "transfer of technology" (ToT). But the United States was reluctant to provide full ToT. Eventually, the plan to purchase Javelins was "shelved" and in October 2014, India chose to buy the Israeli Spike missile system.
