The meaning of «fgm-148 javelin»

The FGM-148 Javelin is an American man-portable fire-and-forget anti-tank missile fielded to replace the M47 Dragon anti-tank missile in US service.[7] It uses automatic infrared guidance that allows the user to seek cover immediately after launch, as opposed to wire-guided systems, like the Dragon, which require the user to guide the weapon throughout the engagement. The Javelin's HEAT warhead is capable of defeating modern tanks by hitting them from above where their armor is thinnest (see top-attack), and is also useful against fortifications in a direct attack flight. As of January 2019, over 5,000 Javelin missiles have been fired in combat.[5]

Javelin is a fire-and-forget missile with lock-on before launch and automatic self-guidance. The system takes a top-attack flight profile against armored vehicles (attacking the top armor, which is generally thinner), but can also take a direct-attack mode for use against buildings, targets inside the minimum top-attack engagement range, and targets under obstructions. The missile also has the ability to engage helicopters in the direct attack mode.[7] It can reach a peak altitude of 150 m (500 ft) in top-attack mode and 60 m (190 ft) in direct-fire mode. It is equipped with an imaging infrared seeker. The tandem warhead is fitted with two shaped charges: a precursor warhead to detonate any explosive reactive armor and a primary warhead to penetrate base armor.

The missile is ejected from the launcher so that it reaches a safe distance from the operator before the main rocket motors ignite – a "soft launch arrangement".[13] This makes it harder to identify the launcher; back-blast from the launch tube still poses a hazard to nearby personnel. Via the "fire-and-forget" system, the firing team may change their position as soon as the missile has been launched or prepare to fire on their next target while the first missile is in the air.[11]

The missile system is most often carried by a two-person team consisting of a gunner and an ammunition bearer, although it can be fired with just one person if necessary. While the gunner aims and fires the missile, the ammo bearer scans for prospective targets, watches for threats, such as enemy vehicles and troops and ensures that personnel and obstacles are clear of the missile's back blast.

In 1983, the United States Army introduced its AAWS-M (Advanced Anti-Tank Weapon System—Medium) requirement and, in 1985, the AAWS-M was approved for development. In August 1986, the Proof-of-Principle (POP) phase of the development began, with a $30 million contract awarded for technical proof demonstrators: Ford Aerospace (laser-beam riding), Hughes Aircraft Missile System Group (imaging infra-red combined with a fiber-optic cable link) and Texas Instruments (imaging infra-red).[14] In late 1988, the POP phase ended and, in June 1989, the full-scale development contract was awarded to a joint venture of Texas Instruments and Martin Marietta (now Raytheon and Lockheed-Martin). The AAWS-M received the designation of FGM-148.
