To be presented at the 16th Summer Symposium on Science and World Affairs, Beijing, July 17 – 25, 2004
Issues to be discussed
Advantages of UAVs for delivery of terrorist’s weapons
Threats posed by small UAVs
Most likely scenarios of UAV application in attacks by terrorists (case of Russia)
UAV composition, technical capabilities and maximum payload
Technical aspects of potential use of commercial radio controlled model airplanes in a terrorist attack
1. Advantages of small UAVs for delivery of terrorist’s weapons
Advantages of UAVs for delivery of terrorist’s weapons
Optimal to attack “area” targets compared to other means of delivery
Relative simplicity of assembling, covertness of preparation and carrying out an attack.
High capability to “penetrate” into areas not accessible by land. It is almost impossible to prevent an attack once UAV is launched.
Long range and high accuracy can be achieved
Relative low cost
Strong psychological effect of an attack on population
Small UAV launch methods

Slide 11
Some lessons of a terrorist attack near Tushino in Moscow, July 5, 2003
Two explosions killed 14 people and injured over 50 (later one more died in a hospital)
Both “shaheed’s belts” consisted of explosives (equivalent to 0.5-1 kg TNT) mixed with small metal items (balls, screws, etc.)
Composition of bombs was not optimal to create maximum energy release. In fact, one of two bombs did not work – its detonator only exploded.That bomb killed the terrorist herself only.
Geometry of the explosions was not optimal as well. People, killed by the second explosion, effectively shielded those who were at a distance of few meters from the explosion.
Terrorists failed to pass through guards to the crowded airfield. Panic was prevented.
More casualties could have occurred, were the attacks from the air.
3. Most likely scenarios of UAV application in attacks by terrorists
How terrorists can get an access to UAVs?
UAVs for military applications
UAVs for civilian applications
Modification of manned aircraft
Small UAVs assembled of commercially available components in a “garage”
Modification of commercially available RC airplane models
4. UAV composition, technical capabilities and maximum payload
Composition of a small UAV
Propulsion+fuel weight fraction
Dimensions of computer and flight control elements
Weight fraction of components for a small UAV
(mtot = 5...60 kg)
Specifications of small reconnaissance UAVs, designed in Russia and Ukraine
5. Some technical aspects of potential use of commercial radio controlled model airplanes in a terrorist attack
Lanier Edge 540T 30% ATF airplane specifications
Expressions for estimates of power required
Power required vs speed
Estimates of maximum range
Maximum range vs speed
The bottom line
It is not technically difficult for terrorists to use small UAVs to carry payloads in a range of 0.5 – 20 kg. Accuracy of a remotely piloted UAV can be better than 20 m, which is enough to conduct an efficient area attack with biological, chemical, radiological weapons or even with conventional explosives. It is very difficult to stop a terrorist UAV, once it is launched.
Attempts to limit the spread of commercially available model airplanes or their components is at least a questionable option, if not a viable one.
One of the strong measures to prevent terrorist’s UAV attacks could be increasing public awareness of the existing threat.
