The LAHAT (laser homing attack or laser homing anti-tank, also a Hebrew word for incandescence) is a third generation semi-active laser homing low-weight anti-tank guided missile developed since 1991 and manufactured by Israel Aerospace Industries. It has a tandem-charge high-explosive anti-tank (HEAT) warhead. It was designed primarily to be fired by Merkava tanks' 105 mm and 120 mm tank guns, though it matches all types of 105 mm and 120 mm guns, including low recoil guns and low-weight guns of military armoured cars.[2]

Key Information

It is also suitable for patrol ships, possibly modified for 105–106 mm recoilless rifles, unmanned aerial vehicles (UAVs), high mobility multipurpose wheeled vehicles (HMMWVs), and self-propelled anti-aircraft weapons (or guns, SPAAGs).[2] Unlike other tank rounds, an LAHAT does not need a tank gun for operation.[3]

Overview

The LAHAT is designed to achieve a 95 percent probability of kill under most conditions.[4] It has a semi-active laser guidance system, capable of both direct and indirect laser designation—the target can be laser-designated by the launching platform (e.g. firing tank) or other platform (e.g. another tank, helicopter, UAV, or forward scouting team), requiring minimal exposure in the firing position. With a low launch signature, the missile's trajectory can be set to match either top attack (armoured fighting vehicle, warship) or direct attack (helicopter gunship) engagements.

The LAHAT missile has a range of up to 8,000 m (5.0 mi) when launched from a ground platform, and up to 13,000 m (8.1 mi) when deployed from high elevation. The time of flight to a target at 4,000 m (2.5 mi) is 14 seconds and the missile hits the target at an accuracy of 0.7 m (2.3 ft) circular error probable (CEP) and an angle of over 30 degrees, providing effective penetration of up to 800 mm (31 in) of rolled homogeneous armour (RHA) steel with its tandem-charge warhead to deal with add-on reactive armor.[5][2] In any tank, the LAHAT is stowed in the ammunition rack and handled otherwise like any other type of ammunition.

The LAHAT was renamed the "Nimrod-SR" for the Latin American market.[6]

The United States military is considering using the LAHAT as a weapon to arm unmanned aerial vehicles. The missile has been tested on the IAI RQ-5 Hunter.[7]

The LAHAT has been successfully test-fired from a helicopter in demonstrations. Eight missiles were launched at targets up to 10 km (6.2 mi) away, from altitudes between 300 and 6,000 ft (91 and 1,829 m). Firings were conducted while the helicopter was hovering, and moving, at targets that were fixed, and moving. One direct hit was scored using the helicopter's observation capability along with laser designation from ground forces.[8]

from Grokipedia
The LAHAT (Laser Homing Anti-Tank) is a third-generation semi-active -guided (ATGM) developed by (IAI), designed for precision engagement of armored vehicles, fortifications, and soft targets with minimal collateral damage. It features a compact design suitable for integration across multiple platforms, including tank gun tubes, helicopters, unmanned aerial vehicles (UAVs), and naval vessels, enabling versatile standoff attacks in diverse operational environments. Development of the LAHAT began in the mid-1990s by IAI's MBT Division as an affordable solution to extend the engagement range of main battle tanks (MBTs) beyond traditional line-of-sight limits, with the missile first unveiled at the Association of the United States Army (AUSA) exhibition in 1998. Early testing included integration with the Indian Army's Arjun tank in 2005 and air-launched variants demonstrated on Mi-8/Mi-17 and MD-500 helicopters that same year, followed by firings from the Bell AH-1 Cobra in 2010. A naval variant was introduced at the IMDEX Asia exhibition in 2011, expanding its applicability to maritime operations. The system has been actively operated by the Israel Defense Forces (IDF) since its inception and exported to countries such as Azerbaijan, where it equips Mi-17 helicopters with quad launchers. The standard LAHAT missile measures approximately 1 meter in length and 105 mm in diameter, with a launch weight of 12.5 to 13 kg, including a 2.5 kg tandem () warhead capable of defeating modern reactive armor. It employs semi-active homing guidance, where targets are designated by external sources such as ground observers, UAVs, or the launching platform itself, achieving a (CEP) of less than 1 meter and reliable performance in GPS-denied or jammed environments. The missile's effective range extends up to 8 to 10 km depending on the launch platform and conditions, with a low launch signature that allows firing from concealed positions and rapid crew egress. It can be fired from 105 mm or 120 mm rifled tank guns, such as those on the MBT, as well as from light vehicles, armored fighting vehicles (AFVs), and rotary-wing aircraft, with training for operators completable in about one week. In October 2025, IAI unveiled the LAHAT ALPHA, an enhanced variant that doubles the standard missile's range to 20 km while increasing its length to 2 meters and weight to 25 kg, incorporating options for a larger or fragmentation payload for broader target engagement. This upgrade addresses demands for beyond-line-of-sight (BLOS) precision strikes at extended standoff distances, maintaining the laser-homing guidance system for jamming resistance and compatibility with existing airborne or ground-based designators. The LAHAT ALPHA is launchable from ground vehicles and helicopters, emphasizing cost-effectiveness and lethality in modern networked battlefields.

Development

Origins

The development of the LAHAT missile was initiated in the mid-1990s by (IAI) to create a lightweight compatible with existing guns. This effort was motivated by the need for a top-attack capable weapon to counter modern armored threats equipped with explosive reactive armor (ERA), prioritizing low weight to enable integration into 105 mm rifled guns on upgraded older s. Initial design goals centered on semi-active homing for enhanced precision, a tandem (HEAT) warhead to defeat ERA, and multi-platform versatility to support diverse launch configurations from the project's inception. Key early milestones included the completion of feasibility studies by the mid-1990s, with particular emphasis on ensuring compatibility with designation systems for effective guidance.

Testing and integration

The development of the LAHAT missile commenced in the mid-1990s under (IAI), with early efforts focusing on airborne testing for integration onto attack and transport helicopters. These tests verified compatibility with systems and fire-control mechanisms, enabling seamless deployment from rotary-wing platforms without major modifications. Following successful ground tests, including a flight demonstration against a stationary target, the missile received its first public unveiling in October 1998 by IAI's MBT Weapon Systems Division at the Association of the exhibition. This reveal highlighted the system's potential as a gun-launched, laser-guided anti-tank solution compatible with existing 105mm rifled guns. Subsequent live-fire trials in the late 1990s and early 2000s validated the LAHAT's performance when fired from 105mm tank guns against armored targets, achieving reliable guidance and impact. By the early 2000s, adaptations extended compatibility to 120mm smoothbore guns, including those on the Merkava main battle tank, through a series of qualification firings that confirmed stable launch dynamics and precision homing. Airborne platform testing expanded in 2005 to include air-launched variants demonstrated on Mi-8/Mi-17 and MD-500 helicopters, as well as integration with the Indian Army's Arjun tank that same year. Testing continued with firings from the Bell AH-1 Cobra in 2010. A primary challenge addressed during testing was the of the missile's guidance and propulsion systems to fit within standard casings, ensuring launch from unmodified tubes without impacting mechanisms or fire rates. Environmental trials also simulated desert conditions prevalent in IDF operational theaters, confirming reliability in high-heat and dusty environments.

Design

Guidance system

The LAHAT missile employs a semi-active (SAL) homing , in which the missile tracks and homes in on the reflected laser energy from a target illuminated by an external designator, such as a ground-based or airborne platform. This mechanism allows for both direct designation by the launching vehicle and indirect designation by third-party sources, including forward observers, helicopters, or UAVs, enabling flexible engagement scenarios while minimizing exposure of the firing platform. The system requires line-of-sight illumination of the target during the terminal phase of flight to maintain guidance until impact, precluding true capability. The seeker's design incorporates a four-quadrant detector housed in the , which facilitates by detecting the position of the spot relative to the missile's centerline and generating steering commands accordingly—a standard configuration for SAL systems operating in the near-infrared spectrum, typically at wavelengths around 1.06 μm from Nd:YAG . This contributes to the missile's high precision, achieving a (CEP) of less than 1 meter under optimal conditions, with reported hits as accurate as 0.7 meters. Flight control is managed through aerodynamic control surfaces, including movable fins equipped with actuators that adjust pitch and yaw for trajectory shaping, such as enabling top-attack profiles to target the thinner upper armor of armored vehicles. The system is compatible with existing laser rangefinders for designation, requiring only minor modifications to the for integration, and can utilize portable or remote designators for beyond-line-of-sight operations. Key advantages of the LAHAT's guidance include reduced due to its pinpoint accuracy, making it suitable for urban environments, and effectiveness against stationary or slow-moving targets at ranges up to 10 km when launched from ground platforms. The low-signature launch further enhances survivability by producing minimal flash or dust, complicating enemy countermeasures.

Structure and warhead

The LAHAT employs a compact cylindrical structure optimized for integration into 105 and 120 tank gun systems, measuring 975 in length and 104.5 in diameter, with a total weight of 12.5 kg that encompasses the tandem and components. is provided by a solid rocket motor that delivers the necessary boost following the initial high-velocity ejection from the gun barrel, enabling sustained flight for engagement ranges up to several kilometers. The features a tandem () configuration, consisting of a precursor charge designed to detonate and neutralize explosive reactive armor () on target vehicles, followed by a primary that achieves penetration of up to 800 mm of rolled homogeneous armor (RHA) after ERA defeat. This design supports high-impact angles exceeding 30 degrees, facilitating top-attack trajectories that exploit thinner upper armor on main battle tanks. The overall construction prioritizes gun-launch survivability, with a low launch signature that produces minimal flash and dust to reduce exposure of the firing platform. The forward section houses a semi-active seeker for target homing, complementing the structural emphasis on precision delivery.

Performance and platforms

Operational range and speed

The LAHAT missile achieves a maximum operational range of 8,000 meters when launched from ground level, extending to 13,000 meters from elevated platforms such as helicopters in hover. This enables stand-off engagements against armored targets while minimizing exposure of the launch platform. The missile's trajectory follows a low-altitude lofted path to evade detection and obstacles during the initial flight phase, transitioning to a top-attack dive in the final 500 meters for optimal impact on vulnerable upper armor surfaces; the minimum engagement range is 500 meters. Fin control surfaces contribute to precise trajectory adjustments during this profile, ensuring stability across varied engagement scenarios. The system operates reliably in varied environmental conditions. Hit probability is designed to achieve 95% under most conditions.

Launch configurations

The LAHAT missile is primarily configured for launch from tank guns, with adaptations for both 105 mm rifled and 120 mm systems. It serves as a cost-effective for older tanks equipped with 105 mm rifled guns, such as the series, where it integrates into existing recoil mechanisms with minimal modifications to the and , which is replaced by a combined /designator module. For modern platforms like the Mk3 and Mk4 tanks using 120 mm guns, the missile employs adapted recoil systems to handle the higher pressures, allowing it to be stored and loaded via the tank's like standard . A four-missile pod for such integrations weighs less than 80 kg, enabling rapid deployment without significant alterations to the vehicle's structure. Helicopter integration utilizes external launch pods, typically carrying four missiles, which attach to platforms like the AH-64 Apache or similar rotary-wing aircraft, benefiting from altitude for augmented range. These pods, also under 80 kg, require integration with the helicopter's fire control and laser designation systems, and the missile has been tested on various export variants including the AH-1 Cobra and Mi-17, demonstrating compatibility with lightweight helicopters for stand-off engagements. For ground and vehicle-based launches, the LAHAT employs portable tripod mounts or integrations on light vehicles such as the , allowing infantry anti-tank teams to operate from concealed positions with manual loading. These configurations support remote laser designation and are suitable for armored fighting vehicles, providing flexibility for mobile forces. Naval adaptations include stabilized launchers on small patrol boats, enabling maritime anti-armor and coastal defense roles from compact vessels. The firing sequence varies by platform: in tanks, missiles load automatically through the following target designation, while , ground, and naval systems rely on manual or semi-automatic loading and often external designators from UAVs, forward observers, or integrated . All configurations use semi-active homing, with the following the designated spot for precision strikes, and produce a low launch signature to minimize exposure. Logistically, the solid-fuel design of the LAHAT requires minimal maintenance, facilitating long-term stockpiling and rapid resupply. for operators across these configurations can be completed in as little as one week, enhancing its appeal for diverse military integrations. As of November 2025, the original LAHAT maintains compatibility with established platforms without reported changes to performance.

Variants

Original LAHAT

The original LAHAT (Laser Homing Anti-Tank) missile, developed by (IAI), represents the baseline version of this semi-active laser-guided (ATGM), optimized for launch from 105 mm or 120 mm tank guns to enable rapid, precise strikes against armored targets. Measuring 975 mm in length and weighing 12.5 kg, its compact design allows integration into existing tank ammunition systems without requiring major modifications to the launch platform. The missile employs a (HEAT) warhead with a penetration capability of 800 mm of rolled homogeneous armor (RHA), effective against modern tanks even at high impact angles typical of top-attack profiles.
