Tow MissileEdit
The Tow missile is one of the most enduring anti-tank guided missiles in modern warfare. Fielded first by the United States Army in the 1970s, the system and its successors have served as a backbone of armored warfare deterrence and battlefield resilience for NATO allies and other partners. Designed to be tube-launched, optically tracked, and wire-guided, the Tow family provides ground troops with a formidable stand-off capability: a firearm-like weapon that allows a trained crew to engage armored targets from a protected position while maintaining control of the flight path throughout the engagement. The missile’s basic concept—an extended guidance wire supplying real-time control signals from the shooter to the missile—has proven adaptable enough to incorporate improvements in guidance, propulsion, and warhead design over several decades. Tube-launched, Optically-tracked, Wire-guided missile is often described by its full acronym and is widely referenced in defense literature and doctrine.
The nature of the Tow system reflects a broader tradition in Western ground-attack guidance: marry a robust, redundant guidance link with a predictable flight path and a direct-attack or top-attack warhead to defeat modern armor. The operator’s role remains central: through a stabilizing sighting system, the crew tracks the target and commands the missile’s course by dragging it through the line of sight via the control wires. This approach trades off some autonomous capability for reliable control in complex environments, where electronic countermeasures and concealment can degrade more autonomous seekers. The Tow family has thus persisted in part because it preserves a simple, proven form of battlefield resilience even as other missiles have shifted toward more autonomous or networked modes of guidance. See also Manual Command to Line of Sight.
History and development
The Tow program emerged during a period of rapid evolution in anti-armor technology. Early fielding in the late 20th century placed Tow in the hands of armored and mechanized infantry units that needed rapid, reliable engagement of enemy main battle tanks from behind cover or at standoff ranges. In many deployments, Tow-equipped platforms replaced older, less capable armor-defeat options and became a standard component of integrated ground warfare. Throughout its history, the system has undergone iterative enhancements to its propulsion, guidance electronics, and warhead configurations to improve armor penetration, range, and reliability under combat conditions. The program’s longevity is a function of ongoing industrial support, interoperability with allied platforms, and the ability to integrate with contemporary fire-control and targeting systems. For context, see Guided missile and Anti-tank guided missile.
A major milestone in Tow’s evolution was the introduction of upgraded variants intended to counter advances in armored protections, including composite and reactive armor. Modernization efforts have emphasized improved penetration against advanced protection schemes, greater top-attack effectiveness, and better compatibility with a wider set of launch platforms. The evolution of Tow also tracks broader debates about how best to deter or counter armored forces on the battlefield, balancing firepower with mobility and force protection.

Design and operation
- Guidance and control: Tow relies on a physical guidance link—a spool of control wires deployed behind the missile in flight. The operator uses a sighting device to keep the target in the line of sight; the commands are transmitted along the wire, steering the missile toward the target. This approach is commonly described as MCLOS (Manual Command to Line of Sight) or SACLOS (Semi-Automatic Command to Line of Sight) in various iterations, with refinements aimed at narrowing the guidance error and improving probability of hit under battlefield stress. See also Wire-guided missile.
- Propulsion and range: The missile is launched from a tubular or shoulder-fired launcher and propelled by a solid rocket motor. Range has varied across variants, with longer reach enabling engagement of armored targets from safer stand-off distances. See also Rocket motor and Anti-tank guided missile.
- Warhead and penetration: Tow variants employ high-penetration warheads designed to defeat modern armor types, including composite and, in some versions, reactive armor. Tandem-warhead configurations have been developed to defeat armor that uses explosive reactive armor or layered protection. See also Armor-Penetrating warhead and Top attack concepts.
- Platform integration: Tow has been adapted to a wide range of launch platforms, including light vehicles, armored fighting vehicles, and helicopters. Prominent platforms have included Bradley Fighting Vehicle, M113, and rotary-wing platforms such as UH-60 Black Hawk and AH-64 Apache in different operating environments. See also Bradley Fighting Vehicle and M113.
The Tow family has also benefited from improvements in compatibility with modern fire-control systems and sensors on vehicles and aircraft. As targeting and fire control become more networked, operators can leverage sensor data to improve aiming accuracy and rate of fire, even as the core guidance principle—manual control along a guided wire—remains in place for reliability in contested environments. See also Fire-control system.
Variants and modernization
The Tow line has seen a sequence of upgrades designed to extend range, improve penetration, and increase counter-countermeasures capabilities. Notable trends include:
- Enhanced warheads: Later variants introduce tandem-charge warheads (to defeat layered armor) and refined explosive formulations to maximize armor defeat while controlling collateral effects.
- Top-attack capability: Newer versions emphasize a top-attack approach to exploit armor’s relatively weaker coverage from above, often coupled with improved trajectory shaping.
- Guidance and countermeasures: Upgrades to guidance electronics reduce drift and improve lock-on stability, while integration with modern countermeasures and counter-countermeasures enhances battlefield survivability against active protection systems and decoys. See also Top attack and Countermeasure.
- Platform versatility: Ongoing modernization aims to maintain compatibility with a broad spectrum of platforms, ensuring logistcs, maintenance, and supply chains remain viable across allied forces. See also M2 Bradley and UH-60 Black Hawk.
A number of national and international defense programs continue to evaluate Tow variants against emerging anti-armor threats, balancing the benefits of a proven, widely-supported system with the push toward newer, networked missiles and guided munitions. See also Raytheon.
Operational use and strategic considerations
Tow missiles have figured prominently in combined arms doctrine where rapid, precise anti-armor fires complement maneuver, infantry, and airpower. In many theaters, Tow-equipped vehicles and helicopters provide a critical counter to armored columns, enabling infantry units to threaten and suppress enemy armor from protected positions. This defensive and offensive versatility has made Tow a mainstay in the arsenals of several allied nations, supporting deterrence by denial and battlefield agility. See also Deterrence and Combined arms.
From a strategic perspective, Tow’s durability stems in part from its established industrial base, interoperability with allied weapons systems, and the ability to sustain operations in varied environments. The continued use of Tow alongside newer guided missiles reflects a pragmatic approach to defense procurement: maintain proven capabilities while gradually integrating advancements in sensors, missiles, and networked targeting. See also Arms industry and Defense procurement.
Controversies and debates surrounding Tow and similar systems typically center on arms policy, alliance commitments, and the broader ethics and consequences of arms proliferation. Proponents argue that providing reliable anti-armor capabilities strengthens deterrence, enhances the safety of troops on the ground, and supports rapid, decisive battlefield outcomes that can shorten conflicts. Critics, by contrast, point to concerns about escalating arms races, the risk of diversion to unstable regimes, and the humanitarian implications of wider anti-armor conflict. Proponents also emphasize the value of exporting interoperable systems to allied nations as a means of shared defense and burden-sharing, while critics warn about dependence on foreign sources for critical defense capabilities and the potential for regional arms imbalances.
