The USS Colorado is the first attack submarine to use an Xbox controller for maneuvering the photonics masts.
Other submarines have joysticks.
The controller operates two photonics masts, which house visible and infrared digital cameras on top of telescoping arms.
Normally, submarines are built with two classic style periscopes.
It is the 15th member of the Virginia class of submarines to join the fleet.
