The missile has four flip-out rectangular raked-tip wings at mid-body and four flip-out rectangular moving control fins at the rear.
Several variants have been fielded. The BGM-71A/B missile has a rounded nose, measures 3 ft 10 in (1.17 m) long, has a diameter of 6 in (150 mm), wing span of 1 ft 6 in (0.45 m), and weighs 42 lb (19 kg). The BGM-71C ITOW is longer at 4 ft 9 in (1.45 m) due to the standoff nose probe. The BGM-71D TOW 2 has an even more extended probe and is 5 ft 0 in (1.53 m) long, diameter of 6 in (152 mm), larger 12.6 lb (5.7 kg) high-explosive warhead and weighs 47 lb (21.5 kg) at launch.
The basic TOW has a 5-in (127-mm) diameter warhead, analog computer and a 3,281-yd (3,000-m) range. Improved TOW (ITOW) added a telescoping stand-off detonation probe. At launch, the two-section probe springs forward to provide the optimum distance between the armor and the exploding high-explosive armor-piercing (HEAP) warhead. The TOW 2 has a three-section probe, a more powerful motor and a 6-in (152-mm) diameter warhead. The TOW 2A is similar to the TOW 2 except that it incorporates a tandem warhead to increase its effectiveness against reactive armor. The precursor warhead in the missile probe detonates the reactive armor allowing the primary warhead to penetrate the tank.
The missile is fitted with a high-intensity thermal beacon, which provides a long-wave infrared tracking source and a xenon beacon for short-wave tracking. This dual-tracking system provides increased resistance to electro-optical and infrared countermeasures.
The standard ground-launched TOW missile system includes a tripod, traversing unit, missile guidance set, launch tube, optical sight, battery assembly and thermal sight for night operations.
Most variants are guided by steering commands transmitted down two wires and controlled by the gunner using the semi-automatic command to line of sight (SACLOS) method. The gunner aligns the crosshairs in the sight unit on the target and presses the trigger. The missile is propelled by the launch motor, which weighs 3.3 lb (1.5 kg) and burns for 0.05 sec.
Once clear of the launch tube, the four wings, indexed at 45 deg, spring open forward, while the tail controls flip open rearward. The flight motor then fires through two lateral nozzles at mid-body. This motor weighs 7.7 lb (3.5 kg) and accelerates the missile for 1.5 sec before burning out. The TOW then coasts to the target at a top speed of 920 ft/sec (280 m/sec). The gunner keeps the crosshairs centered on the target using a joystick on the sight unit until the missile hits.
The TOW has been fitted to a wide variety of platforms. Helicopter platforms include the AH-1 Cobra , A109 Hirundo, A129 Mangusta , Bell 206, Bell 406, BO-105 , Dauphin , AS350 Ecureuil, SA341 Gazelle , MD500 Defender , Sikorsky ACH-76 and Westland Lynx . Vehicle variants include the improved TOW vehicle (ITV ) M901 , LAV(AT) anti-tank, M2 Bradley , M3 Bradley , YPR-765 PRAT armored infantry fighting vehicle (AIFV) and Jaguar II (JPZ4-5 Jagdpanzer with TOW). (Many of these systems are covered in separate records.)
Many unarmored vehicles, including "jeeps" and M998-series High Mobility Multi-Purpose Wheeled Vehicles (HMMWVs), can carry one or more TOW mounts.

The BGM-71 was developed for the U.S. Army in the mid-1960s as a replacement for the 106-mm recoilless rifle and SS-11 missiles. Production began in 1968 after successful demonstration firings.
Initial operational capability (IOC) TOW/BGM-71A in 1970, ITOW/BGM-71C in 1982, TOW 2/BGM-71D in 1984, TOW 2A/BGM-71E in 1987 and TOW 2B/BGM-71F in 1992 (first unit equipped). Over 650,000 TOWs have been built and are in service with more than 40 armed forces. TOW missiles are expected to remain in U.S. service beyond 2050, according to Raytheon.
In January 1992, the Spanish joint venture firm Guiado y Control (composed of Hughes and INISEL) won a Spanish Defense Ministry US$130 million contract to manufacture TOWs; additional orders were expected through 1996.
A production contract for 976 TOW 2B Aero missiles was awarded to Raytheon in February of 2004. Deliveries were completed in December of 2006.
On June 4, 2004, Raytheon was awarded a $123 million contract for 2,700 TOW missiles, including TOW 2B Aero, TOW 2B and TOW practice rounds, for the U.S. Army and Marines, as well as international customers.
In April of 2005, the Army awarded a contract to Raytheon to restart production of the TOW Improved Target Acquisition System (ITAS). There were 709 systems procured between 1999 and 2003.
In August of 2005, Kuwait ordered 436 TOW missiles (292 TOW 2A, 144 TOW 2B).
On Sept. 15, 2006, Raytheon received a $163.2 million contract to supply wireless TOW 2B RF missiles to the U.S. military. The deal included five one-year options for additional weapons.
Raytheon announced it had been awarded a $161.8 million Army contract on Dec. 4, 2006, to extend production and delivery of Improved Target Acquisition Systems (ITAS).
On Dec. 7, 2006, the U.S. Defense Security Cooperation Agency notified Congress of a potential Foreign Military Sale to Pakistan of TOW 2A missiles. The potential deal, worth up to US$185 million, included 2,769 radio frequency TOW 2A missiles; seven RF TOW 2A fly-to-buy missiles; 415 RF Bunker Buster missiles; seven RF Bunker Buster fly-to-buy missiles; and the upgrade of 121 TOW Basic/TOW-I launchers to fire TOW 2 configuration for wire-guided and wireless missiles, TOW data acquisition systems, gunner aiming sight and related equipment, spare and repair parts.
On Oct. 29, 2007, the U.S. Defense Security Cooperation Agency notified Congress of a potential foreign military sale to Israel of various missiles and munitions. The possible sale included 2,000 radio frequency TOW 2A missiles and 14 RF TOW 2A fly-to-buy missiles.
Raytheon received a US$17 million contract in November 2007 to build 462 TOW Bunker Buster missiles for the Canadian army. The deal marked the first international sale of TOW Bunker Buster missiles. The weapons delivered to Canada were to be equipped with the new wireless radio frequency command data link.
On Jan. 3, 2008, the Defense Security Cooperation Agency announced that Kuwait sought to buy TOW 2A/B radio frequency missiles from the United States. The possible sale, worth up to $328 million, covered 2,106 TOW 2A RF missiles plus 21 buy-to-fly missiles, and 1,404 TOW 2B RF missiles plus 14 buy-to-fly missiles, as well as containers, spare and repair parts and logistics services. The missiles were needed to enhance the reliability of Kuwait's stock of existing TOWs, which were nearing the end of their service lives.
The Defense Security Cooperation Agency announced on Sept. 9, 2008, that Egypt requested the sale of TOW 2A missiles under the Foreign Military Sales program. The potential deal, worth up to US$319 million, covered 6,900 missiles plus 28 fly-to-buy missiles, as well as containers, spare and repair parts and associated logistics support. Egypt required the missiles to update its aging inventory, the agency told the U.S. Congress.
On June 14, 2010, Raytheon said it would develop an airborne launcher designed to employ radio frequency-guided TOW missiles. The launcher would be compatible with all past, current and future versions of the TOW, according to a company release. The upgrade package would be initially available to AH-1 Cobra attack helicopter users and integrated with Northrop Grumman's suite of glass-cockpit upgrades, Raytheon officials said. This is currently only an export program.
Raytheon announced that it had received a $55 million contract on July 18, 2010, to deliver TOW 2A RF missiles as part of a Foreign Military Sale to Saudi Arabia. TOW RF missiles include an RF transmitter added to the missile case and an RF receiver located inside the missile.
On Sept. 14, 2011, the U.S. Defense Security Cooperation Agency announced a potential US$53 million contract with Bahrain for Humvees, TOW missiles and associated parts and logistical support. The possible deal covered 44 M1152A1B2 armored HMMWVs; 200 BGM-71E-4B-RF radio frequency TOW-2A; 7 fly-to-buy RF TOW-2A Missiles; 40 BGM-71F-3-RF TOW-2B aero missiles; 7 fly-to-buy RF TOW-2B aero missiles; 50 BGM-71H-1RF Bunker Buster missiles (TOW-2A); 7 fly-to-buy RF Bunker Buster missiles (TOW-2A); 48 TOW-2 launchers; AN/UAS-12A night sight sets, spare and repair parts and associated logistics support.
Raytheon announced on Feb. 28, 2012, that it had successfully tested a TOW missile with a new propulsion system developed by Alliant Techsystems (ATK). The launch, boost, sustain (LBS) propulsion system also incorporates a rocket motor designed with insensitive munitions (IM) features for additional safety. The propulsion system doubles TOW's range and reduces the missile's flight time by one-third, according to Raytheon. During the trial, the missile flew more than 4 miles (7 km), reaching 2.5 mi (4 km) in significantly less time than baseline weapons.

The warhead weighs 13 lb (6.09 kg), with the precursor charge at the front of the extending nose probe and the main charge at the front of the missile body. It features an improved K-41 solid-propellant motor that accelerates the missile to a top speed of 1,020 ft/sec (310 m/sec). Maximum range is 2.5 mi (4 km) and it takes 21 sec to reach 2.33 mi (3.75 km).
Over 34,000 have been delivered. A wireless version is available, which offers greater reliability, improved over-water performance, no power line restrictions and enhanced combined arms applications in various environments.
Hughes (now Raytheon Missile Systems) received a development contract for the TOW-2A in 1987.
The BGM-71F does not have a nose probe. It is 3 ft 10 in (1.17 m) long and weighs 50 lb (22.7 kg). The warhead weighs 13.5 lb (6.14 kg).
In operation, the gunner sights on the tank, while the missile flight path is biased upward to overfly the target at a predetermined height.
Following problems with U.S.-designed fuzes, the Army adopted a version of the British Thorn-EMI proximity fuze used in the FITOW.
A development contract for the TOW 2B was awarded in 1988. Army development and flight testing was completed in October 1990. Limited production was approved in December 1990 with first deliveries in 1992.
The Marine Corps has selected the TOW 2B Aero with the improved target acquisition system (ITAS) for its next-generation anti-armor weapon system-heavy (AAWS-H) program.
The TOW Bunker Buster is also scheduled to receive the wireless RF guidance data link.
This variant is slated to equip the anti-tank guided missile (ATGM) variant of the Stryker armored vehicle.
The missile was announced in 1988 and entered production in late 1991. In 1994, the FITOW entered British Army Air Corps service, fitted to Lynx AH7 helicopters.
Weight of missile in container is 65 lb. (29.5 kg); tripod, night sight, guidance equipment and batteries add an additional 158.7 lb. (72 kg). Length is 4 ft 9 in (1.45 m), diameter 5.8 in (148 mm). Speed is 1,033 ft/sec (315 m/sec) and time to 4,374 yds (4,000 m) is 19.5 seconds. Penetration is more than 1,000 mm RHA (rolled homogeneous armor).
In production by Israel Aircraft Industries.
Production for the U.S. Army began in 2006.
The ITAS includes a second-generation FLIR using Standard Advanced Dewar Assembly (SADA II) technology and an eyesafe laser rangefinder, which doubles the system's detection and identification ranges. It also features an automatic boresighting capability, aided target tracking, embedded training, BIT/BITE and traversing unit modifications to increase the weapon's standoff range.
Canada has purchased the ITAS for integration with its TOW-armed LAV-III vehicles.
The latest upgrade of the ITAS incorporates a global positioning satellite-based position attitude determination subsystem (PADS). When used with the laser rangefinder, the system provides a far target location (FTL) capability that provides gunners with precise 10-digit grid coordinates for their own position and for the selected target. The new capability makes it possible to direct other weapon system fires and to call in close-air support (CAS) or indirect artillery fires. The ITAS FTL capability was used operationally in Afghanistan for the first time in May 2008 by Destiny Co., 2nd Bn, 503rd Infantry (Airborne (AB)), 173rd AB Brigade Combat Team (BCT).
No TOW motors were produced at the Hercules -managed Radford, Va., plant between May and December 1986, because of problems in cold-weather firing and crumbling propellant. The delay affected almost 11,000 TOW missile bodies. Full-production capacity was reached again in mid-1987.
Two TOW missile explosions in September 1986 were unrelated to the Hercules propellant problem, but were linked to stress corrosion in the motor cases of TOWs produced before 1986. A plastic coating on new motor cases was recommended as a preventative measure.
Soon after the TOW 2A was announced in 1987, evidence suggested that some Russian tanks had stacked reactive armor, the first layer of which detonates the probe, leaving the inner layer to deflect the HEAT warhead. Another armor option would be a light layer of laminate armor over the reactive armor. The TOW 2B was expected to be able to defeat such measures by virtue of its depressed angle of attack from above.
An after-action report by the Marine Corps Systems Command following the March-April 2003 war in Iraq stated that operators were extremely happy with the performance of the TOW-2A and TOW-2B. There were some concerns that the sensors in the TOW-2B could be distracted when fired over large metal objects such as those found in and around oil fields, but the TOW-2A reportedly did not display this problem. One major complaint registered by all Marines interviewed in the report said operators needed to be cross-trained on the older and newer TOW sights. Some operators reportedly had difficulty identifying targets, while others would follow the missile with the sight rather than keeping it trained on the target. This resulted in the missile flying higher and higher unless the operator corrected the mistake and refocused on the target in time.
Israeli forces used TOWs in the 1973 Arab-Israeli War and the 1982 invasion of Lebanon.
The Moroccan air force is known to have employed TOWs against POLISARIO units in the Western Sahara.
Iranian forces used TOWs against Iraqi tanks during the 1980-1988 Gulf War.
In 1987, Pakistan utilized TOW IIs against Indian forces in the conflict over the glacier region.
For Desert Storm, TOWs were deployed by the U.S. Army and Marine Corps as well as by the British, Royal Saudi, Egyptian and Kuwaiti armies in far greater numbers than any other ground- or vehicle-based anti-tank missile. In the Marine Corps alone, for example, 582 M220E4 TOW launchers were deployed with the 1st Marine Expeditionary Force (MEF) in Saudi Arabia. Another 96 launchers remained with troops embarked on landing ships in the northern Gulf.
During preparations for the ground war, TOW-equipped Marine Corps LAV-25s reconnoitered Iraqi border positions, using the missiles as bunker busters as well as against armored vehicles. At the battle of Khafji (Jan. 30-31, 1991), Saudi TOW-equipped M113s engaged tanks as well as hitting bunkers. U.S. Marine Corps Cobras with TOWs also supported the Saudi-Qatari counterattack.
Marine Corps AH-1W Cobras also figured prominently in the Marine and Saudi drive on Kuwait City. In one incident, a LAV-25 unit was surprised by an Iraqi force of T-62 tanks near a burning oil field, as described in Aviation Week. Four Cobras attacked through breaks in the oily murk and destroyed several tanks with TOWs. Altogether, 250 TOWs were fired by Marine Corps units.
U.S. Army Cobra -TOW helicopters escorted the 101st Airborne Division's airlift into southern Iraq at the start of the ground war. British Lynx AH7s were credited with destroying several tanks during the U.S. VII Corps' sweep around the Iraqi right flank.
The U.S. Marine Corps used TOW-2A and TOW-2B in Iraq in the spring of 2003, with several operators reporting catastrophic kills when used against Iraqi T-72 tanks. The conflict marked the first operational firing of the TOW 2B.
British marine Lynx AH7 helicopters also utilized TOW missiles during the invasion of Iraq in 2003.
Raytheon says that about 1,000 TOW missiles were fired in Afghanistan in 2009 and another 2,000 were utilized during the first six months of 2010. The figures included TOW 2A, 2B and Bunker Buster missiles. Production of TOW 2A missiles was restarted after the top-attack TOW 2B was found to be less effective in combat in Afghanistan.
