One of my favorite gags in the Navy was getting a bunch of guys together on the main deck and cheering on the submarine races when some newbies came aboard at sea. The dense ones would watch and watch not understanding why we could see the subs and they couldn’t.

 

 

When I was in high school taking a date to the drive in theater the term “submarine races” had an entirely different meaning.

And they called you surface guys "skimmers!"  ^_^

No Targets.

My brother was on the USS Kamehameha SSBN 642. I was on the USS Nimitz CVA 68 a really big target.

And by the way he said it was Sub-marine-er.

He gave me a T shirt that had a periscope superimposed over a picture of a surface ship with the saying "Hi skimmer" on the front and on the back surface ship broke in two and sinking with the saying "Bye skimmer".  I wore it until it was rags.

CVN 68??  CVAN 68??   or is that something swabbies don't pay attention to?  Excuse me, skimmers?

 

Since modern subs, don't have real periscopes, I presume there is no more "up scope". is the view now just a screen somewhere?

 

 

 

NOTE: this is intended to be a 'humorous' comment.

 

Subs will GPS their location to a satellite.   The Sat will send a photo and GPS location of area vessels.   The computer geeks will cypher everything and tell the boat Commander all pertinent info.   Then, the Sub Commander will know where everybody is located when & if he ever has to fire a Trident (or other) at NK  (Nutty Kim)

:D

 Between the three of us, one of us should

   be able to determine where we are! :P

Periscopes still go up and down.

They are stored in the sail and telescope up when needed.

They no longer go through the hull but are connected by digital cables for the cameras and other equipment in the periscope head.

SUB Question   (and NO, I don't know the answer)

 

How deep can a Sub (modern day Nuclear Sub)  be and have usage of its periscope?

 

Is the depth sufficient to hide any signs of a wake on the waters surface?

According to HOW STUFF WORKS, the periscope on a modern nuke can be as long as 60 feet, which for some damn reason they added in parentheses (18 meters) instead of (10 fathoms) like they shoulda.

It's a "Photonics Mast" instead of a periscope...  all electronic.

 

And uses an off-the-shelf X-box controller.  :)

I will venture the SWAG that fathoms is down for depth, not up or other directions the boats length, etc, is never given in fathoms for example.

Fathoms is a depth of water. If the scope is 60 feet long, and is only extended when the boat is under water, then it seems that the length of the scope should also be in fathoms.

 

And when the boat is at "periscope depth", which would be sixty feet below the surface, they would be ten fathoms.

 

Buuut - you're probably right. I googled "nuclear sub periscope depth", where it said that scopes could be up to 60 feet (18 meters) in length, so periscope depth would be that deep. Since they were talking "deep", I translated it in my mind.

 

Either way, it should not have mentioned "meters". We're 'MURICA!, dammit, and we don't do no dang meters. :P

Fathom is a measure of distance below the surface of water.

With subs, the reference point is the keel. In other words, "periscope depth" is the height of an extended periscope added to the distance to the bottom of the sub.

My bad. When I first got on the ship it was CVAN 68. Sometime later the Navy changed it to CVN. I have a ships belt buckle with CVAN on it and a Zippo lighter with CVN on it. Is it any wonder why I was confused?

CV        Aircraft Carrier

CVA      Aircraft Carrier, Attack

CVN    Aircraft Carrier, Nuclear Powered

CVAN   Aircraft Carrier, Attack, Nuclear Powered

 

The CVA and CVAN designation was changed to CV and CVN respectively in the mid 70s when the Navy decided that all aircraft carriers were multi-mission capable..

The ex-collier USS Langley AC-3 was rebuilt and recommissioned as the first US aircraft carrier CV-1 on 20 March 1922. The CVB designation was approved by the Secretary of the Navy on 10 June 1943 and the CVL designation was approved on 15 July 1943. The CVS designation was established in 1953 with USS Bunker Hill (CVS-17) being the first so designated on 8 August 1953, although she was in reserve at the time and never did recommission. The designation CVA replaced both CV and CVB on 1 October 1952. CVL went out of use on 15 May 1959 when the last light carrier was decommissioned. With the decommissioning of the last CVS in 1974, CV and CVN replaced CVA and CVAN on 30 June 1975 as carriers were now considered to be multi-mission capable rather than specialized. The CV (non-nuclear) designation went out of service when the last conventionally powered carrier, USS Kitty Hawk CV-63, was decommissioned on 12 May 2009.

Escort Aircraft Carriers were originally designated AVG (Escort Carrier, Auxiliary) on 31 March 1941, with the USS Long Island AVG-1 being the first ship so commissioned on 2 June 1941. This designation was changed on 20 August 1942 to ACV (Aircraft Carrier, Auxiliary), and then changed again on 15 July 1943 to CVE. Escort Carriers built for the British Royal Navy were designated BAVG until they were transferred. The CVE designation went out of use when the remaining escort carriers were reclassified AKV (Auxiliary, Aircraft Ferry) on 7 May 1959.

This thread had me looking up Nimitz, and then checking out the Independence (the Big I, the latest and the greatest). That's what Daddy called her when he was on her. Launched in '59, did a shakedown in the Caribbean, then did a Med cruise. That Med cruise was Daddy's last sea duty before he retired.

 

I remember he was gone a while, but I was 4 goin' on 5. Didn't realize it was that long. August of '60 to March of '61. SEVEN MONTHS. Wow.

I made 3 Med cruises on the Nimitz. The first 2 were 7 months but the third was the better part of 9 months. 10 Sep 1979 to 26 May 1980. The last of it was 144 days at sea. That was when the Iranians took over the embassy. We started out as a Med cruise and ended up being an Indian ocean cruise.
