The US is sending Ukraine 100 Switchblade "kamikaze" drones as part of a bigger military package announced by President Joe Biden.

Drone war has already given Ukraine some battlefield successes and the new weapon will be a lethal addition.

· Despite looking like a mini-aeroplane, Switchblades are more like a "smart bomb".

· The 300 model weighs 2.7 kilograms and fits into a rucksack. It is 60 centimetres long and can fly for up to 15 minutes.

· They are launched like a mortar. Once in the air, their wings unfold.

· They have on-board video cameras and colour sensors to aid with guidance.

· They are essentially camera-equipped, remote-controlled flying bombs that can be directed by an operator to find a target then, when ready, plunge on to it. They explode on contact, hence the "kamikaze" nickname.

Switchblades extend the range of attack on Russian vehicles and units to beyond the sight of the user. That gives them an advantage over the guided heat-seeking missiles the Ukrainians have used against Russian tanks.

The dive-bombing Switchblade, made by AeroVironment, has been used by US commandos since it was secretly sent to Afghanistan in 2010 for use against the Taliban.

The larger 600 model is effective against armoured targets and can fly for more than 40 minutes. It was not immediately known which models are being sent to Ukraine.

The Switchblade cruises at 100kph and provides “operators with real-time video downlinks for a centralised view of the area of operation” and also has a “wave-off capability” to adjust targets in flight.

Turkish drones in Ukraine

Ukrainian forces already have a fleet of Turkish-made drones that drop precision-guided weapons.

The Bayraktar TB2 unmanned aerial vehicles, which carry lightweight, laser-guided bombs, normally excel in low-tech conflicts.

They carried out unexpectedly successful attacks in the early stages of Ukraine’s conflict with Russia, before the Russians were able to set up their air defences in the battlefield, said land warfare expert Jack Watling, of the Royal United Services Institute in London.

“The (TB2s) shouldn’t be making a meaningful impact because they are medium altitude, slow-flying aircraft with a large electromagnetic signature and a large radar cross-section. And the Russians have very capable air defence systems, so they should be being shot down. The terrain is very open and gives good radar coverage,” Mr Watling said.

He said Ukrainian forces “have been essentially flying in at a low-level and then coming up and raiding with them. So striking targets of opportunity”.

In a briefing to the British Parliament, Defence Minister Ben Wallace praised the drones, as he did other weapons donated to Ukraine by the West.

“One of the ways they are delivering close air support or actual fire in depth is through the Turkish TB2 UAVs, which are delivering munitions on to their artillery and indeed their supply lines, which are incredibly important in order to slow down or block the Russian advance,” Mr Wallace said.

Turkey began selling the TB2 drones to Ukraine in 2019.
