Which of the following is not an example of shipboard ordnance handling equipment?

Cranes are indeed considered an example of shipboard ordnance handling equipment. They are specifically designed for lifting and moving heavy loads, such as ammunition and ordnance, on a ship.

In the context of shipboard operations, all of the listed equipment types—lifting jacks, forklifts, and conveyors—serve critical roles in the safe handling and movement of ordnance. Lifting jacks assist with vertical lifting tasks, forklifts are versatile for transporting payloads across the deck, and conveyors facilitate the efficient movement of materials.

Choosing cranes as not being part of ordnance handling equipment would overlook their crucial function in ensuring the safe and effective logistical operations onboard an aircraft carrier. Understanding the roles of each type of equipment is essential for proper ordnance handling and safety practices within a naval environment.
