Yes, that’s correct. It also proves the Ukrainians aren’t able to fly those fancy aircraft the West gave them and fire them from the air.
SDB’s are mainly obsolete in the face of modern SAM defenses - unless you can use an F35 to drop them. They are small and fit in an F35 shielded internal bomb bay. The US made tons of them in the 2000’s. There are better stand-off weapons now. Hence they are surplus in the USAF.
The “fancy aircraft” the Ukes now have are 1980’s models with 1990s upgrades, secondhand from various Euro countries. Whats this “fancy”?
