Narrative:
Descending into iad at approximately 4;500 ft. And 250 knots; inside mcque intersection on the mapel 2 arrival for runway 19L; the captain's windshield suddenly shattered. The captain was looking down at the time; however both the [relief pilot] and myself; the flying first officer; saw something strike the windshield. The captain's windshield was completely shattered (but the inner pane was still intact) so I took over and landed the aircraft at his direction. There were no injuries. At first we assumed that this was a bird strike; however after landing we examined the window both inside and outside with maintenance and we saw no evidence of any bird remains or blood. After further reflection; we felt that this very possibly could have been a drone strike; as there was a clear area on the windshield showing where something hit it; with the cracks radiating from it; but with no evidence of biological material.
