Watched a program last nite (don't remember the full name of the show) about the building of the Virginia class boat. How they got the shape of it, ( the Albacore)
to it's reactor and living environment. A very well done show. They
were building the 788 boat at the time of filming. I realize many of you
guys know about this since you may have been on a nuke. But to those of
us that haven't, it's all "Flash Gordon" stuff. The thing I don't
understand is the photo thingy, that takes the place of the periscope.
How can that not be seen when they raise it. It's big and fat and it's
profile is about 10x larger (wider) then an attack scope. Can anyone
explain...without giving away to much? Much in awe of the Virginia Class...Sure wish I could take a ride on one.

You'd think she was still tied to the pier what with the lack of noise you were used to. |

From what I know about the photonics mast, they do not have to leave it
up for too long. It takes a 360 degree photo. Then they can lower it, and zoom
in on any part of the screen, to see what it looks like on the surface. There
was a display about it at the Sub Force museum in Groton a few years ago. I think Kollmorgen makes them; they made a
lot of scopes, just up the road from where I live. Edited by 3boatphil - 23 Mar 2019 at 5:12am |

Amazing, WWII Radar could pick up a german periscope. Now we have something a lot bigger, coming up against wildly advanced technology, and it can't be found? Must have the same technology as a stealth bomber.

Walt,
Had I done everything right throughout my life, the World wouldn't have noticed. |

Think of it this way, Joe. You want to take a photo of someone around the corner. Get the camera ready, poke it out, push the shutter button, and pull it back. The time that it was visible around the corner is minimized.
From what I understand, the new mast can be raised, take a 360° photo, save it to the computer and, and be retracted in a matter of seconds, then the photo can be analyzed at leisure from the monitors. Plus, as said above, the mast itself has stealth capabilities so as not to be visible on radars. Where with the old periscope it had to be rotated to see what was up there, the Captain had to visually analyze what he saw. That took much more time.

Laser range finders,infra-red camera, definitely Star Wars stuff. What next, "Use the Force, Luke" when you have the Fire Control Tracking Party stationed?
Something else to think about: Boats no longer have propellers, they have Propulsors. Edited by 3boatphil - 23 Mar 2019 at 8:07pm |

Just a Sunday ping. Boats had screws not propellers. Have a good one.

"Images are recorded on both video cassette and CD-ROM." This part already seems like old technology. Updated since the article was written?

Next thing we'll read is that they are using Xbox 360 Contollers to control the new Photonics Masts. Oh, wait. Edited by SaltiDawg - 24 Mar 2019 at 4:43pm |
