Final answer:
The term 'quad-cons' does not correspond to known equipment in the U.S. Navy. Without more context, it isn't possible to provide a precise number of 'quad-cons'.
Step-by-step explanation:
The term "quad-cons" is not a standard term in the context of the United States Navy or military equipment. Therefore, it is not possible to provide a specific number of "quad-cons" that the Navy has. If the question is referring to a specific piece of equipment or program, please provide additional details, and I will be happy to assist further. Generally, the U.S. Navy has various equipment and assets that could be mistakenly referred to with the term "quad-cons", such as quadcopter drones for reconnaissance or logistics purposes.
