"I’ve heard various estimates from the Ukrainians themselves that any given drone typically has a life span of about four weeks." Maybe if referring to the Mavic scouts or bombers... Because the FPVs and Cessna-based drones have a lifetime based on mission duration. They have an outsized impact, however. I also must say that expensive gear from Anduuril is a drop in the bucket compared to homegrown sea and air drone assets. It has become a diy drone war through and through. Nothing like 2022.
