Ukrainian command reports Russian drones camouflaged for night warfare

“We are familiar with the modifications they are using,” Humeniuk said.

“They are painted in darker colors — different shades of black, carbon, and dark gray — to blend in with the night sky.”

The Shaheds also often exhibit different sound characteristics, with some flying louder and some quieter.

There has yet to be a conclusion reached regarding whether they have a reinforced warhead, Humeniuk said.

“Experts hypothesize that some drones may possess a reinforced warhead,” she said.

The Iranian Ashura Aerospace University of Science & Technology in the fall presented a modification of the Shahed-136 strike drone, which has a jet engine and updated guidance systems — the Shahed-238.
