From the article: "The sea drone was reported to be equipped with a R-73 air-to-air missile."

Maybe. More likely it was armed with a missile made by a U.S/British/German/French konglomerate.

“...as £38m fighter jet shot down by Ukrainian sea drone”

I suspect that by the time the drone reached the plane it was already in the water.
