Photonic Masts - The Astron Class does not have conventional periscopes. Instead, it has two AN/BVS-1 Photonic Masts. Advantages of this are:
Non-Hull Penetrating
Includes low light TV, a thermal imager, and a laser range finder
Two workstations
Photonics mast workstation and Command workstation
Two displays on each workstation
Upper display for real time video
Lower display for real time, recorded, or still frames
A handgrip is used to control the sensor head, select views, select contacts, and take still frames
Additional information on the powerplant/propulsion system:
With the Astron Class submarine, we utilize an advanced hydrogen fuel cell system that allows the submarine to operate on battery power for weeks. Albeit, a nuclear powered system would allow us to sustain months, it also is nosier comprimising the main advantage to submarines.. and what they thrive on, acoustic stealth. Since the nuclear reactors pumps must be on, we developed the AIP. The AIP allows the submarine to submerge for weeks without refueling(snorkeling). This allows the submarine to maintain the advantage of submerging for a long period of time, without the noise.
Other Innovations:
Modular Isolated Deck Structure (MIDS)
The entire command center will be installed as one unit on cushioned mounts
Will utilize Commercial Off the Shelf (COTS) components which allows for easy upgrade to new state of the art technology. Much cheaper then refits required for previous submarines to upgrade to new technology.
Fly-by-wire:
The helm and dive controls will be replaced by a four axis joystick.
Redundant electronic data buses operated by a fault tolerant set of processors to control the operator?s commands to the control surfaces.
This replaces the use of hydraulic controls between the ship control station and the control surfaces.
Price: 2.5 billion
