A loitering munition is an uncrewed aircraft that carries its own warhead, circles above a target area for minutes or hours, and destroys itself in the act of hitting the target — it does not return to base like an armed drone such as the MQ-9 Reaper. An operator watching an onboard camera feed, or in some designs the munition’s own seeker, confirms the target and then flies the aircraft straight into it. The result sits between a cruise missile and a reusable combat drone: cheaper and shorter-ranged than most cruise missiles, but expendable and built to be destroyed on every mission, unlike a drone that fires a missile and flies home. Loitering munitions are also widely called suicide drones or kamikaze drones.

How Does a Loitering Munition Work?
Most loitering munitions follow the same sequence. The weapon is launched from a tube, a rail or a small catapult, climbs to altitude and flies to a search area under its own power rather than a ballistic or purely pre-set flight path. An onboard camera, usually electro-optical and sometimes infrared, streams video back to an operator over a data link while the munition circles — “loiters” — waiting for a target to appear or be designated. Once the operator confirms the target, or a pre-programmed set of coordinates is reached on simpler designs, the munition dives and detonates its warhead on impact. If no valid target is found, most designs can abort the strike, re-attack later or self-destruct, which is the main advantage over a one-shot artillery round or an unguided rocket fired on uncertain information.
Loitering Munition vs Drone: What’s the Difference?
The two are easy to confuse because both are small, uncrewed and camera-equipped, but the business model is different. An armed reconnaissance drone such as the MQ-9 Reaper or Bayraktar TB2 is a reusable aircraft: it carries one or more missiles or guided bombs, releases them, and flies back to be refuelled and re-armed. A loitering munition is the warhead itself — airframe, sensor and explosive are consumed on every strike, so the whole aircraft is lost whether or not it hits anything. That trade-off is what makes loitering munitions cheap enough to mass-produce and expend by the thousand in a way no reusable drone fleet could sustain, at the cost of losing the airframe on every single engagement.
| Weapon | Reusable? | Typical range / endurance | Example systems |
|---|---|---|---|
| Loitering munition | No — expended on every strike | Short to medium (tens to a few hundred km, 15–120 min loiter) | Switchblade (US), STM KARGU (Türkiye), Lancet (Russia) |
| Armed drone / UCAV | Yes — returns and is re-armed | Hundreds to thousands of km, hours of endurance | MQ-9 Reaper (US), Bayraktar TB2/Akinci (Türkiye) |
| Cruise missile | No — but flies a set course to a fixed target, not a search pattern | Hundreds to thousands of km, no loiter | Tomahawk (US), ROKETSAN SOM (Türkiye) |
Main Types
Tactical, man-portable systems weigh a few kilograms, are carried and launched by a single soldier from a tube, and are used against individual vehicles, fighting positions or dismounted troops at ranges of a few kilometres to a few dozen kilometres; AeroVironment’s Switchblade 300 and STM’s rotary-wing KARGU are typical examples. Larger, longer-range one-way attack systems weigh tens to hundreds of kilograms, are usually launched from a rail or a simple catapult rather than carried by hand, and are built to reach targets tens to hundreds of kilometres away, trading the fine man-portable form factor for reach and a bigger warhead; Russia’s Lancet and Sudan’s Safaroog fall in this category. A separate strand, often blurred with the FPV (first-person-view) drones improvised in large numbers in Ukraine, uses cheap racing-drone components with an added warhead rather than a purpose-built munition body.
Advantages
A loitering munition lets an operator hold a weapon over a target area and wait for the right moment to strike, rather than committing to a fixed aim point the way an artillery shell or unguided rocket does, which cuts the risk of missing a moving target or hitting the wrong one. Because the airframe is simple and built to be destroyed, unit costs are a fraction of a cruise missile or a guided bomb plus the aircraft that carries it, which is why forces with limited air power — from Ukraine and Russia to Sudan’s warring factions — have been able to field thousands of them. The same low cost and small radar signature also let smaller or sanctioned militaries build a precision-strike capability without buying or maintaining crewed strike aircraft.
Limitations
Every loitering munition is lost on every mission, hit or miss, so cost-effectiveness depends on not using an expensive munition against a low-value target. Most tactical designs have limited loiter time (typically under two hours) and are vulnerable to the same electronic warfare and counter-UAS defences — jamming, directed-energy weapons and point-defence guns — used against other small drones, since most rely on a radio data link and GNSS for navigation. Weather, dust and poor visibility also degrade the electro-optical sensors most designs depend on for final targeting.
Why It Matters
Loitering munitions have become one of the defining weapons of conflicts since the 2020 Nagorno-Karabakh war and the war in Ukraine, where both sides have used them by the thousand against armour, artillery and air-defence radars. For militaries across Africa and the Middle East facing budget limits, sanctions exposure or an adversary with its own drone fleet, a loitering munition offers a precision-strike option that does not require a crewed strike aircraft, an expensive guided-missile inventory or the air superiority needed to use either safely.
Examples in Africa
Sudan’s Military Industry Corporation (MIC) has developed the Kamin-25, a UAV-launched loitering munition carrying a roughly 5 kg anti-tank or 7 kg anti-personnel warhead, first displayed at IDEX 2023 and tested from the Sudanese Air Force’s own Z3-M drone, alongside the longer-range Safaroog one-way attack drone MIC unveiled at IDEF 2025 with a reported range of up to 600 km (status: fielded/in testing with Sudanese forces in the ongoing civil war, per Janes’ and Military Africa’s reporting on the programme) Janes, Army Recognition. DefenceMENA has covered the wider drone war between Sudan’s army and the Rapid Support Forces in depth; see DefenceMENA’s report on drones in the Sudan war, our comparison of loitering munitions used by African armies and the Sudan tag desk.
Examples in the Middle East
Yemen’s Houthi movement has used the Iranian-origin Samad and earlier Qasef families of long-range, one-way attack drones against targets inside Saudi Arabia for several years, including repeated strikes and intercepted attacks aimed at Saudi oil infrastructure and Riyadh (status: reported — Riyadh and allied governments attribute the design lineage and components to Iran, which Tehran denies, and the Houthis themselves claim the strikes) CSIS Missile Threat, Oryx. See DefenceMENA’s own coverage of the most recent round of Houthi strikes on Saudi Arabia, Houthis claim missile strike on Saudi Arabia’s Ras Tanura refinery, the Saudi Arabia military-strength pillar and the Saudi Arabia tag desk.
Turkish Example
STM’s KARGU family — a rotary-wing, quadcopter-style loitering munition carrying an explosive or armour-piercing warhead — entered Turkish Armed Forces service in 2018 and has since been used by Turkish forces in counter-terrorism operations, with STM saying more than ten countries now operate the system (status: in service). In January 2026, The Defense Post reported that STM signed its first export contract bringing the KARGU and the smaller fixed-wing ALPAGU loitering munition to a NATO and EU member state in Europe, STM’s first confirmed sale of the family inside the EU/NATO area (status: exported, contract signed) The Defense Post; STM’s own announcements describe continuing armour-piercing warhead testing on the KARGU line STM. STM also exhibited the KARGU alongside its TOGAN and KUZGUN unmanned systems at AFRIDEX 2026 in Nigeria, part of a wider Turkish defence-industry push into African markets; see DefenceMENA’s report on Türkiye’s presence at AFRIDEX 2026, one verified Envanter Medya technical page comparing the KARGU-2 with the US Switchblade 300, kargu-2-switchblade-300-karsilastirma, and the Türkiye tag desk.
Commonly Confused Terms
A loitering munition is often mixed up with an armed UAV, but the difference is reusability: a drone returns after firing its weapon, a loitering munition is the weapon and is lost on every strike. It is also distinct from a cruise missile, which flies a set course to a pre-planned target rather than circling an area to search for one, and from an FPV (first-person-view) kamikaze drone, which is usually an improvised, off-the-shelf racing-drone airframe fitted with a warhead rather than a purpose-built weapon. Its vulnerability to jamming links it to electronic warfare and to the counter-UAS systems built specifically to defeat small drones and loitering munitions.
Definition: An uncrewed, expendable aircraft that carries its own warhead, circles a target area, and destroys itself by flying into the target it identifies.

Frequently Asked Questions
What is a loitering munition?
A loitering munition is an uncrewed aircraft that carries its own warhead, circles above a target area, and destroys itself by crashing into the target it identifies, rather than releasing a separate missile or bomb.
What is the difference between a loitering munition and a drone?
A drone such as an armed UAV is reusable: it fires a missile or drops a bomb and flies back to base. A loitering munition is the munition itself and is destroyed on every strike, whether or not it hits a target.
Is a loitering munition the same as a kamikaze drone?
Yes — “kamikaze drone,” “suicide drone” and “one-way attack drone” are all common names for the same category of weapon as “loitering munition,” though some militaries now separate simple, pre-programmed one-way attack drones from loitering munitions that can circle and wait for a target.
How is a loitering munition different from a cruise missile?
Both are one-way, expendable weapons, but a cruise missile flies a planned route to a fixed target and is generally larger, faster and longer-ranged, while a loitering munition is built to circle a search area and wait for a target to appear before attacking.
How far can a loitering munition fly?
It varies hugely by design. Tactical, man-portable systems typically operate at a few to a few dozen kilometres with 15–40 minutes of loiter time; larger one-way attack drones such as Sudan’s Safaroog or Russia’s Geran/Shahed-type systems are reported to reach hundreds to over a thousand kilometres.
