Answer: Yes, because the helicopter manufacturer assumed the risk of the failure of the contract.
Step-by-step explanation:
Based on the scenario given in the question, the subcontractor will likely prevail because the helicopter manufacturer assumed the risk of the failure of the contract.
Here, when the helicopter manufacturer entered into the contract with the subcontractor, the manufacturer was aware that the helicopters will be used in the "severely war-torn region.
In this case, the subcontractor wasn't aware of the information that the manufacturer knew of and therefore wasn't able to determine the risk that was involved in the contract.
