[9] The weapon made its combat debut in Iraq in 2003 and rose to prominence in the Russo-Ukrainian War, where it saw extensive usage by Ukrainian forces during the early stages of the 2022 Russian invasion.
In what is known as a "soft launch arrangement," the missile is ejected from the launcher to a safe distance from the operator before the main rocket motors ignite.
[19] In August 1986, the proof-of-principle (POP) phase of development began, with a US$30 million contract awarded for technical proof demonstrators: Ford Aerospace (laser-beam riding), Hughes Aircraft Missile System Group (imaging infrared combined with a fiber-optic cable link) and Texas Instruments (imaging infrared).
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.
[24] The gunner carries a reusable command launch unit (CLU, pronounced "clue"), which is the targeting component of the two-part system.
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.
It is also used to scan immediately before sunrise and after sunset, when it is difficult to focus the thermal image due to the natural rapid heating or cooling of the environment.
Once the CLU has been focused in WFOV, the gunner may switch to a narrow field of view (NFOV) for target recognition before activating the seeker FOV.
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.
Features of the lightweight CLU are: a long-wave infrared (IR) thermographic camera; a high-definition display with improved resolution; integrated handgrips; a five megapixel color camera; a laser point that can be seen visibly or through IR; a far target locator using GPS, a laser rangefinder, a heading sensor, and modernized electronics.
[26] The LW CLU has demonstrated the ability to fire a FIM-92 Stinger anti-aircraft missile, using its superior optics to identify and destroy small unmanned aerial vehicles (UAVs).
The ESAF system enables the firing and arming process to proceed, while imposing a series of safety checks on the missile.
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.
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.
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 seeker consists of three main components: focal plane array image sensor, cooling and calibration, and stabilization.
In other applications, a CLU's IR detectors are cooled using a Dewar flask and a closed-cycle Stirling engine, but there is insufficient space in the missile for a similar solution.
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.
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.
The signals from each of the 4,096 detector elements (64×64 pixel array) in the seeker are passed to the FPA readout integrated circuits which reads then creates a video frame that is sent to the tracker system for processing.
If this position is off center, the tracker computes a correction and passes it to the guidance system, which makes the appropriate adjustments to the four movable tail fins.
The soldiers must accomplish several timed drills with set standards, before being qualified to operate the system in both training and wartime situations.
This is most commonly only minor requirements left out due to budget, the number of soldiers vs. simulation equipment, and available time and resources.
The Javelin was used by the US Army, the US Marine Corps and the Australian Special Forces in the 2003 invasion of Iraq,[11] on Iraqi Type 69 and Lion of Babylon tanks.
During the Battle of Debecka Pass, a platoon of US Army Special Forces operators equipped with Javelins destroyed two T-55 tanks, eight armored personnel carriers, and four troop transport trucks.
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.
[citation needed] 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 ~300 m range was insufficient.
[1] The Javelin had enough range, power, and accuracy for dismounted infantry to counter standoff engagement tactics employed by enemy weapons.
[35] In 2016, claims were posted on social media that the Syrian Kurdish People's Protection Units (YPG) may have received Javelin missiles.
[43][44][45][46] Iran reportedly received an example of the Javelin missile from Russia, along with other Western munitions captured in Ukraine, as part of a larger deal for Shahed and Mohajer drones.
