In January 2022, with satellite imagery revealing Russian forces massing on Ukraine's borders and intelligence agencies warning of an imminent invasion, the United Kingdom made a bold and consequential decision: begin a rapid airlift of 2,000 NLAW anti-tank missiles to Ukraine, the first tranche of what would grow to approximately 6,000 NLAWs delivered before Russia launched its full-scale invasion on February 24. This was the most significant pre-conflict arms delivery by any NATO member to Ukraine, and the NLAW — a jointly developed British-Swedish single-shot disposable anti-tank weapon — would prove to be one of the decisive weapons of the war's critical first phase, contributing to the defeat of Russia's armored thrust toward Kyiv.
NLAW System Overview
The Next Generation Light Anti-Tank Weapon (NLAW), designated MBT LAW (Main Battle Tank Light Anti-tank Weapon) in its development phase and officially LMAW in Swedish service, is a man-portable, single-shot disposable anti-tank weapon designed to defeat any existing main battle tank. Key specifications: weight 12.5 kg (one-man portable); length 1,016 mm; effective range 20–800 m (primary use 50–500 m); guidance — Predicted Line-of-Sight (PLOS) with 3-second lock-on before firing; warhead — HEAT (High-Explosive Anti-Tank) shaped charge with 500+ mm RHA penetration; detonation options — overfly proximity mode (over top armor) or direct attack mode (frontal assault); operation temperature range −38°C to +63°C; shelf life 10+ years with minimal maintenance. Can be fired from enclosed spaces due to soft-launch mechanism with a rear combustion discharge that is non-lethal at 2m behind the launcher in open air but hazardous without clearance. Single crew with approximately 3–6 hours of training can achieve operational proficiency.
Development: Saab and Thales Partnership
NLAW was jointly developed by Saab Dynamics (Sweden) and Thales Air Defence (UK) from the 1990s through the 2000s, driven by a British Army requirement for a modern replacement for the aging LAW 80 and as a complement to Javelin for shorter-range engagements. The UK signed its first production contract in 2002, and the weapon entered service with the British Army in 2009. Sweden adopted it as the PSKOTT 08 (Pansarskott m/08) in 2009. The weapon was designed from the outset to be affordable and simple enough for use by infantry soldiers without specialized training — in contrast to the more complex and expensive Javelin, which requires missile gunners to complete lengthy qualification courses. Saab manufactures the weapon at its Karlskoga facility in Sweden. The UK became the world's largest operator with approximately 14,000 units in service before its decision to transfer substantial quantities to Ukraine. The Swedish government's decision to donate from its own stocks (alongside independent Saab production) reflected the high strategic priority both nations placed on Ukraine's defense — Sweden's donation notably came before its formal NATO membership.
Technical Capability: Overfly Attack Mode
The NLAW's defining tactical capability is its Overfly Attack Mode (OAM). During the 3-second pre-fire tracking phase, the weapon's Inertial Measurement Unit (IMU) records the target's movement vector. At the moment of firing, PLOS guidance directs the missile not at the target's current position but at the predicted intercept point — where the target will be when the missile arrives. The missile's flight path rises slightly above the predicted line-of-sight to the target. When the proximity fuze (operating on a magnetometer detecting the metal mass of the tank below) detects the vehicle, a downward-angled shaped charge detonates, directing its penetrating jet downward into the tank's thinnest armor — the roof. Russian main battle tank top armor ranges from approximately 20 mm (T-72 variants) to 40 mm (T-90M Breakthrough) — versus 400–600 mm frontal hull equivalent. Modern ERA (explosive reactive armor) panels, which are effective against standard frontal HEAT warheads, offer virtually no protection against top-attack. The result: NLAW's overfly mode can defeat any tank currently in service. The weapon also has a WSAR (Weapon Safety Arming Range) setting for close-range direct attack against lightly armored vehicles or at distances where overfly mode is not appropriate.
Pre-Invasion Delivery: UK's January 2022 Decision
Britain's decision to airlift NLAWs was made by the Boris Johnson government in January 2022 over objections from other NATO allies who feared the move would provoke Russia. The UK argued that Ukraine had the legal right to defend itself and that defensive anti-tank weapons were not escalatory. Royal Air Force C-17 Globemaster III transport aircraft flew directly to Boryspil Airport, Kyiv, delivering the first 2,000 NLAWs in the final weeks of January 2022. A second tranche followed in February before the invasion. Total UK NLAW delivery before February 24: approximately 6,000 units — enough to equip thousands of Ukrainian infantry fighting positions throughout the country. The deliveries were accompanied by British Army instructors who provided accelerated training to Ukrainian troops directly in Ukraine. When the invasion launched on February 24, Ukrainian forces had NLAWs waiting in pre-positioned ambush positions. The speed of distribution — to territorial defense units, regular army infantry, and national guard — was enabled by the weapon's simplicity and the pre-training conducted in preceding weeks.
Other Donor Countries
In addition to the UK's approximately 10,000 total NLAW contribution, NATO allies augmented Ukraine's NLAW stockpile substantially: Sweden donated approximately 5,000 units from Swedish Armed Forces stocks — a remarkable decision for a then-non-NATO nation under pressure from Russia not to arm Ukraine; Finland provided approximately 2,500 NLAWs from its own stockpiles; Lithuania and other Baltic states provided small numbers. Total NLAW deliveries across all donors through 2023 are estimated at 14,000–18,000 units, making NLAW the single most numerous individual anti-tank weapon system delivered to Ukraine. Combined with approximately 7,000+ Javelin missiles, additional AT4 rockets, Carl Gustaf rounds, and Ukrainian Stugna-P ATGM production, Ukraine's infantry anti-armor capability in the first year of the war was by far the largest concentration of disposable anti-armor weapons deployed in combat since World War II.
NLAW in the Battle for Kyiv: February–March 2022
When Russia's armored columns advanced on Kyiv from Belarus through Chernihiv and directly via Hostomel from February 24–26, they encountered NLAWs in the hands of Ukrainian defenders at multiple chokepoints. The most significant engagements occurred on the Hostomel airport approach road (where the airborne assault to seize the airport was supported by ground armor that met fierce resistance), along the Irpin-Bucha-Gostomel axis, and on the routes west of Kyiv through Makariv. Video footage that circulated internationally showed NLAW fires against Russian armor at close range; the weapon's disposable nature meant it could be used by territorial defense volunteers, not just trained anti-tank specialists. Documented impacts: hundreds of Russian armored vehicles were destroyed or damaged on the Kyiv approaches before Russia's March 25 announcement of "withdrawal" from northern Ukraine. While NLAW was one of several contributing factors (alongside Stugna-P ATGM, artillery, Bayraktar TB2 strikes, and Russian logistics failures), British military analysts judged NLAW contribution as decisive: "NLAW was the weapon that stopped the Russian advance on Kyiv" — British Chief of the Defence Staff Admiral Sir Tony Radakin, March 2023.
NLAW vs Javelin: Comparison
NLAW and Javelin are complementary rather than competing systems: NLAW is shorter range (maximum 800 m vs Javelin's 4,000 m), lighter (12.5 kg vs Javelin's 22.3 kg system weight), simpler to operate (hours vs weeks of training), cheaper (~£30,000 vs ~$250,000 per Javelin round), and disposable (fire and discard vs Javelin's reusable Command Launch Unit). Javelin offers fire-and-forget autonomous tracking after lock-on, longer range, and can be used in direct attack mode against helicopters and UAVs. NLAW requires operator to track target for 3 seconds before firing (not fire-and-forget) but has a shorter minimum range (20 m vs Javelin's 75 m). Both use top-attack. In Ukrainian practice: Javelin was reserved for longer-range engagements, high-value armor, and situations where fire-and-forget was operationally important; NLAW filled the close-range defensive role, being ideal for infantry in urban areas, tree lines, and trench systems. The complementary use of both weapons — along with Ukrainian Stugna-P (similar to Kornet) for 5,000 m+ anti-armor — created a multi-range anti-armor defensive system that Russian doctrine had not anticipated in such density.
Later War Use: 2022–2026
After the Kyiv campaign, NLAW continued to be used throughout the war though its prominence diminished relative to other weapons as the conflict transitioned to attritional trench warfare in eastern and southern Ukraine. In built-up areas like Kharkiv, Mykolaiv, Kherson, and during the Bakhmut battles, NLAW's short-range close-quarters capability remained relevant for defending buildings and narrow urban corridors where FPV drones could not easily operate and Javelin's minimum range was too large. As FPV drone production scaled to hundreds of thousands per month by 2023–2024, FPV drones at $500 per unit became more economical than the £30,000 NLAW for anti-armor use — though NLAW remained valuable for situations requiring immediate certain response without reliance on drone operator availability. UK supply of NLAW continued throughout the war, as did training for Ukrainian operators. By 2026 estimates, a significant portion of Ukraine's pre-war NLAW stockpile had been expended in the first year of combat, with ongoing UK and allied production replenishing the supply.
Strategic Assessment: Did NLAW Save Kyiv?
The counterfactual "what if Ukraine had not received NLAWs before the invasion" is debated among military analysts. The consensus assessment: NLAW was necessary but not sufficient. The defense of Kyiv resulted from multiple factors — Russian logistical failures (fuel, food, maintenance), poor Russian planning and overconfidence, Ukrainian territorial defense mobilization, the defense of Hostomel airport from Russian airborne assault, effective use of artillery, and the psychological resilience of President Zelensky's decision to remain in Kyiv. However, without the 6,000+ NLAWs in Ukrainian hands, Russian armor would have moved faster and with less attrition along the approach roads: territorial defense units, which had NLAW but often not Javelin or Stugna-P, would have had little anti-armor capability. The speed of pre-invasion UK delivery — getting 6,000 weapons in Ukrainian soldiers' hands before February 24 — was almost certainly more important than any subsequent delivery. The strategic lesson: pre-positioned defensive anti-tank weapons in sufficient quantities to equip all defenders before an armored assault are a highly cost-effective deterrence and defense investment. At approximately £180 million for 6,000 NLAWs, the UK investment arguably prevented a Russian seizure of Kyiv that would have cost the West many times more in subsequent military and economic support.
Frequently Asked Questions
How many NLAWs were provided to Ukraine?
The UK delivered approximately 6,000 NLAWs before the invasion on 24 February 2022, in a series of RAF C-17 airlifts beginning in late January. Total UK contribution through 2023 reached approximately 10,000. Sweden added approximately 5,000 from its own service stocks; Finland, Lithuania, and others added further units. Total NLAW deliveries across all donors: estimated 14,000–18,000 units — making it the most numerically significant individual anti-tank weapon delivered to Ukraine, exceeding even US Javelin deliveries by unit count.
How does the NLAW work — what is the overfly attack mode?
NLAW uses Predicted Line-of-Sight (PLOS): operator tracks target for 3 seconds, the weapon calculates its speed and direction, then fires to the predicted intercept point. In Overfly Attack Mode, the missile passes over the tank and fires a downward-shaped charge when the proximity fuze detects the vehicle — striking the 20–40 mm top armor which is the tank's weakest point. No ERA (explosive reactive armor) protects against top-attack. Weighs 12.5 kg, range 20–800 m, single-use disposable, a few hours of training required. Can kill any MBT in service from WW2 through 2026.
Did NLAW help stop Russia's advance on Kyiv?
Yes — British military leadership assessed NLAW as critical to defeating Russia's northern thrust. Territorial defense volunteers with NLAWs ambushed Russian armored columns on the Hostomel-Kyiv and Bucha-Kyiv approach roads in late February and early March 2022. The weapon's light weight, ease of use, close-range capability, and overfly top-attack mode made it ideal for defenders in built-up areas and forests along the approach routes. Russia's failure to take Kyiv resulted from multiple factors — but NLAW's role was assessed as decisive in degrading the pace and momentum of Russian armor before Russia's March 25 withdrawal announcement.
What is the cost of the NLAW Anti-Tank Missile Ukraine: How 10,000 Missiles Helped Stop Russia's Kyiv Advance compared to what it destroys?
