These were designed to replace the ageing Los Angeles class submarines. The Virginia-class incorporates several innovations not previously seen in other submarine classes. Instead of a traditional periscope, the class utilizes a pair of telescoping photonics masts located outside the pressure hull. Each mast contains high-resolution cameras, along with light-intensification and infrared sensors, an infrared laser rangefinder, and an integrated Electronic Support Measures (ESM) array.
