The court previously heard that the group, dressed in red jumpsuits, used a decommissioned prison van to crash into security shutters at the Elbit site, armed with tools.
Prosecutor Deanna Heer KC told the court: “Inside the warehouse, they set about destroying as much property as they could.
“They used crowbars and hammers to damage computers, equipment, drones and other products Elbit had manufactured,” she said.
“Their role was to cause as much damage as possible until they were forcibly stopped.”
An estimated £1m worth of damage was caused during the raid.
The group said they aimed to destroy what they believed were combat drones and other military equipment that would be used by the Israeli Defence Forces in Gaza.
There has been no evidence in the case as to what the factory produced.
