Obzirom na aktuelnost bespilotnih letelica, a posebno onih manjih, te problema koji se javljaju u borbi protiv njih, otvaram potpuno novu temu koja ce se baviti svim sistemima koji omogucavaju efikasnu odbranu od istih.
Kako je u pitanju relativno nov izvor opasnosti, smatram da se svetski proizvodjaci PVO sistema jos uvek nisu dovoljno snasli oko pronalazenja odgovarajuceg odgovora na male BPL, koje moze lansirati i koristiti samo jedan covek. Ekstremno veliku opasnost u buducnosti ce predstavljati mini- i mikro-BPL, kao sredstvo nesimetricnog ratovanja.
U ovom trenutku jos uvek se luta - jedni proizvodjaci i oruzane snage krenuli su putem lasera, drugi putem elektromagnetnih "topova", treci i dalje veruju u metak i raketu.
Ovo je tekst koji je objavila Armada International - april/maj 2016:
Citat:The all-weather Drone Dome has 360° circular coverage, and uses an electro-optical/infrared sensor and radar to detect a threat. The data is then combined and correlated and alerts the operator of the hostile UAV.
The system initiates either an automatic interference operation – as per pre-defined rules – or it is carried out manually by the operator. The threat is neutralised by activation of directional GNSS and a radiofrequency inhibitor/jammer.
Citat:The DroneDefender is designed to jam electromagnetic waves, causing the drone pilot on the ground to lose control of their UAV. And with a range of about 400 meters (roughly four football fields), it can even reach your neighbors on the other side of the tracks.
The Department of Homeland Security and the Department of Defense reportedly already have about 100 of these things. But the DroneDefender will no doubt face plenty of resistance when it comes to being commercially available to the public—most especially from the FCC.
Citat:And just think, once Amazon gets it drone delivery system up and running in earnest, you can literally shoot down free shit from the air.
‘Be vewy, vewy, qwiet. I’m hunting an iPad. Huhuhuhuhuhuh’.
Citat:The system provides a comprehensive solution against drones’ threats, including detecting and identifying hostile drone activity, automatic tracking of detected drones and disruption of their activity or neutralization of drones before they can carry out their missions. The Red Sky Drone Defender includes a volumetric search radar and thermal sensors for target acquisition at ranges up to six kilometers. Powerful directional radio-frequency (RF) datalink and GPS jammer provides a ‘soft kill’ neutralization capability at distances of 2-3 kilometers. For hard-kill of targets at shorter range the system will be able to use high-power fiber laser.
Citat:DroneGun is a portable rifle-style jammer, which can operate independently of any other sensors, to locate and neutralize potential aerial threats. The ‘rifle’ is connected to a backpack that stores the RF transmitter and batteries. The system requires no calibration and is instantly ready for operation when switched on. It can operate for two hours and requires 90 minutes of charging.
Citat:The RAYSUN MD1 is a counter drone system that is designed to disrupt and neutralise unmanned aerial vehicles unmanned aerial vehicle (UAV).
The shoulder rifle can interfere with radio frequency of the drone within 3 seconds to trick it into believing it’s out of range of the owner, then the drone is programmed to either return to the owner, make a controlled descent, or fall out of the sky.The device allows to control ISM or GPS signal individually, for example, the user can only cut down ISM signal while keep GPS working to track the UAV owner’s position and destroy it.
The RAYSUN MD1 MD1 UAV jammer can work 24h and carry out the mission at any time by using with the thermal scope.

Programirana granata za (podcevne)bacace granata 40 mm.
Citat:ST Kinetics, the land systems and speciality vehicles arm of Singapore Technologies Engineering (ST Engineering), is expanding its portfolio of 40 mm ammunition with the counter-unmanned aircraft system (C-UAS) and the door-breaching grenades.
According to company specifications, the C-UAS grenade – which has an overall length of 125 mm and weight of 243 g – has been in development since 2017 and is specifically designed to defeat small, commercially available, multirotor unmanned aerial vehicles (UAVs).
A typical package comprises the 40 mm C-UAS grenade and a rail-mounted programming unit, with the latter measuring 95 mm long, 45 mm wide, 60 mm tall, and weighing 350 g. The warhead carries a payload streamer, which is delivered into the flight path of a UAV and disable its propellers, forcing it to crash.
The programming unit, which is mounted via a MIL-STD 1913 accessory rail on a rifle or grenade launcher’s 3 o’clock position, features an integral laser rangefinder with a range of 500 m.
The C-UAS grenade is designed to compatible with a wide range of grenade launchers on the market, including the STK 40GL, HK69A1, M203, M79, AG36, MK13, M32A1, Milkor and Rippel Effect MGL. Launched at a muzzle velocity of 100 m/s, the round has a stated maximum range of 600 m, although Jane’s understands from an ST Kinetics spokesperson that the typical engagement range is around 200-300 m given the potential challenges of targeting small UAVs at further distances.
“[To increase success] we can program grenade bursts in three locations – what we call the ‘string of pearls’ – increase the coverage,” a company spokesperson explained to Jane’s . “For example, if a target is 100 m away we can set the rounds to burst at intervals of 90 m, 100 m, and 110 m to saturate a wide area with streamers.”
