"Made by a subsidiary of the Kalashnikov concern, the Lancet 3 weighs about thirty pounds, and has a distinctive profile thanks to its X-shaped wings. The weapon used is claimed to be a new, upgraded version of the Lancet-3 with an eleven-pound warhead compared to the original seven-pound one, and is distinguished by the larger wingspan."

Early version (smaller warhead):
Looks like a reverse engineered Israeli "Hero" loitering munition:
"Lancet has a shaped-charge warhead, a type that focuses its energy into a narrow, armor-piercing jet, which is highly visible in many of the strikes, passing right through the target and out the other side. This enables it to attack even heavily-armored targets like tanks. However, it is not powerful enough to go through a tank’s frontal armor."...
"in several of the videos, soldiers on the ground scatter in the seconds before the Lancet strikes. This suggests that it is highly audible or visible or both, and alert troops can get out of the way. They might also shoot it down – the Ukrainians claim to have brought down a number of Lancets with just small arms fire."...
"The nearest equivalent to the Lancet-3 on the Ukrainian side are probably the Phoenix Ghost provided by the U.S. along with the Warmate supplied by Poland; the smaller Switchblade-300 is mainly an antipersonnel weapon and the Switchblade-600 is yet to arrive."
