Do not take anything posted as fact this is an aid to self education. 

 

To understand USN hull codes is to understand the military mindset and practice of the time. Before the 1920's USN just largely used numbers with a single letter to designate its purpose. During the 1920's the navy decided to reorganize its classification systems. The first letter described the hulls design the letter following its job.

 

Auxiliary ships get A they are ships that aren't front line fighting ships.

Not going to try to go over roles there are to many.

 

Battleships are always BB. Battleship hull, Battleship role.

 

Side note had the Lexington class been a true Battleship hull their designation would of been BV Battleship hull, fixed wing aViation role not CV. If the USN had built Sharnhorst she would of been a BC or Battleship hull, Cruiser role.

 

Cruiser hulls on the other hand are more convoluted.

 

A really stands for Armored role. Which is a hold over from Armored Cruiser but they were called heavy cruisers most of the time as treaties designated them so. Cruiser hull, heAvy role was any cruiser with guns above 6 inches to the treaty limit of 8 inch.

 

 L means two things, Leader and Light armored role as these cruiser were designed as destroyer flotilla Leaders at first or Lightly armored cruisers. It was changed to mean any cruiser with gun under 6 inches due to treaty. Many heavy cruisers were originally classed as light armor and leader roles by the USN. But, treaties signed at the time said any ship with 6-8 guns were deemed to be of a heavy cruiser role and subject to greater limits on production than that of light cruiser role. Which was anything with guns below 6 inches and L was changed to designate this.

 

 V stands for fixed wing aViation role. Hence carriers are Cruiser hulls with the role being to handle fixed wing aViation. AC you would think be logical but no that was originally used for Armored Cruiser also the original doctrine of carriers was largely a cruiser style role supporting the Battle line ships. Also A is used for Auxiliary hull which a carrier is not an auxiliary hull. 

 

B stand for Battleship. I.E. Cruiser hull Battleship role. Only the Alaska class to date. She in theory was a Battlecruiser but she was designed to hunt cruisers and not take on battleships her self. Alaska had 12 inch guns not allowed by treaty but the treaty was largely broken by the time she was designed.

 

 

C stands for Cruiser role. CC would be a dedicated fleet cruiser. Lexingtons were for the most part battlecruisers but they were not really purposed to be battlecruisers as much they were to be large strong fleet cruisers with large guns. She was supposed to engage if terms were favorable and run if not report the fined back to the fleet. CA largely filled the role and which is why the USN ultimately changed C role to mean command not cruiser. CC wasn't really used until post war.

 

E was for the Escort role rarely used on Cruiser out side of CVE

 

 

Destroyer hull roles aren't as confusing as cruiser in fact the really was only three major roles.

 

D is for Destroyer role hence DD is a dedicated fleet Destroyer.

 

L was for the Leader role the USN didn't feel a cruiser hull was always needed to lead destroyer flotillas so these larger destroyers were design to perform the same role.

 

E is for Escort role as in DE they were to protect convoys typically were geared for anti submarine warfare were cheap and slow. Later replaced by the Frigate designation. DDE were converted from fleet Destroyers.

 

Frigate wasn't used until post war to replace DE and Corvette hasn't been used by the USN yet in modern time.

Thanks I was hoping to get to Destroyers, Frigates, and Corvettes later.

Sorry again about that, I thought I was helping.

Why are your threads so weird? And why do you get upset when others help?

Point to the point I said don't help. I said I was finishing up later. I have no plans for coast guard and I am curious about those.

One of my Late Uncles was retired from the USCG (served during WWII), so when I went into the Navy we used to tease each other all the time:Smile_smile:

Well there are times I think all of us are.

After all we spend a lot of time in front of the computer playing with "toy" ships:Smile_teethhappy:

Fox, you're incorrect in saying that the "V" in CV stands for aviation.  The V designation for heavier-than-air craft comes from the French verb "voler" (to fly).

See first post very top. But that is not normal for the US military to use French and even the source of that was guessing. The US military has always had the habit of using the second letter in a word for an abbreviation in classification if the first letter was used elsewhere and in this A was used for Armored. Which forces V to be used for aViation.

My source is my military family and friends who told me this over and over.

The problem here is that your military family bought into the myth.  And you're wrong that the US military didn't use the French as a source for codes here.  Also, why is it that aircraft squadrons in the Navy all start with a "V"?  Same reason as CV's.  V means voler, i.e. to fly, in French.

Try using sources better than hearsay.

Quite. Though you might change the title to "Greyfox discovers USN ship hull designation."

Good point sight yours. That source never explains why Z was used for light than air despite the obvious reason.

Wasn't this largely known already to those in the know at least.
