Some new technologies that the US, UK and Russia are putting in place

(To Antonino Lombardi)

Combat drones increasingly dominate the modern battlefield, as is evident in the war in Ukraine.

The UK1 has been developing not only increasingly advanced UAVs for some time now, but also ground drones for scanning dangerous environments.

The VIKING Multirole UGV (opening photo) is a platform designed and built to - among various options - supply the military and front-line vehicles without exposing the troops to dangers. Equipped with independent suspension, it has four steering wheels that increase control and maneuverability on challenging terrain, it can reach a road speed of 50 km / h and carry up to 750 kg of load.

The engine is hybrid propulsion. It can travel up to 20km on battery power and around 200km on a full tank of diesel.

Il Defense Science and Technology Laboratory (DSTL) and the FALCON Squadron, 28 Engineer Regiment (C-CBRN) of the British Army conducted a field exercise that simulated VIKING's capabilities in detecting hazardous material environments. The payload included two mass spectrometers, two vapor sensors and a gamma radiation spectrometer to detect ground chemicals, volatile chemicals, and radioactive hazards.

The US Navy, for its part, is developing the Torpedo-Tube Underwater Drone Recovery System a torpedo launch and recovery system for underwater drones launched from nuclear attack submarines.

Il Razorback (photo), the size of a torpedo, has been tested on Navy attack vessels for more than a year, but requires a dry deck and divers for UV recovery (unmanned underwater vehicle, ed) of 270Kg.

Vice Admiral Bill Huston said that "The Medium UUV can go on any of our submarines. This is for us a priority. We have no problem launching UUV. It's easy. The recovery part is the critical aspect. "

The same underwater drone, with different adaptations, will also be used for explosive ordnance disposal operations allowing vehicles to enter deeper waters and improve the overall effectiveness of mine countermeasure operations in non-permissive environments.

In Russia, however, the company PPSh Laboratory 2 presented an electronic war rifle capable of blocking unmanned aerial vehicles.

The LPD-802 device, an update of the LPD-801, allows you to block the control channels of the drones and the navigation signals by disabling the signals of the wi-fi satellite system and the GNSS, canceling the transmission of data.

The system is expected to be successful in blocking drones using frequency bands within the 2,4GHz, 5,1GHz and 5,8GHz navigation channels.

LPD-802 can operate in both automatic and manual modes and its battery can offer continuous operation of approximately 60 minutes. The total weight is 3,5 kilograms and can block a target from a distance of up to 1,5 kilometers by emitting radiation of up to 10 watts.
