Protesters are planning to target a Lichfield factory again next month.
Nineteen people were charged during previous day of action at Shenstone-based UAV Engines last year.
Campaigners say the Lynn Lane factory supplies engines for drones used by Israel to bomb Palestine.
A new protest is being planned for July 6:
Protest: Stop Elbit Arming Israel 6th July. 11am-4pm.
