The latest security package includes 121 tactical drones called the Phoenix Ghost.

The drones were developed quickly by the Air Force in response to Ukrainian requirements, according to John Kirby.

It provides the same capabilities as the Switchblade series, but not exact. Kirby said that there are other differences in the scope of capability for the Phoenix Ghosts, but that he wouldn't be able to give more detail about those capabilities right now.

The drones manufactured by Aevex are in the U.S. Air Force. Kirby told reporters that U.S. troops will have to train Ukrainian forces on how to operate drones. He did not say when the drones would arrive.

The U.S. has committed at least 300 Switchblade drones from AeroVironment. The Switchblade 300 and 600 are the two versions of the weapon. It wasn't immediately clear which version the U.S. deployed.

The 300 variant is designed to hit small targets. It can fit in a backpack with a range of 10 miles. The weapon is designed to destroy armored vehicles. It has a range of more than 40 miles and is slightly more than 120 pounds.
