I want to double check some facts about US Aircraft Carriers, Nimitz class.

1. According to what what I've been finding, the height of the flight deck above the water is 57' (fifty-seven feet). This seems low to me, but I don't know.

2. It seems the term "bolter" is used to describe an aircraft that fails to grab the arrestor cable.

Thanks for any help.

Best of luck,

Jim Clark-Dawe

I believe this is correct (I've never served in the Navy, though). The way I've heard it used is "the pilot had to bolter and go around for another try."

It sounds about right. Most of the WW2 ones were around 50', although they were smaller. I don't suppose you'd want a high carrier because it would roll too much and be easier to sink. I seem to recall that the hangar is about 25' high on the Nimitz Class an it occupies about half the above water space (i.e. height). So again, it sounds about right.

My dad served on the California, which was a nuclear-powered guided missile cruiser tasked with protecting the Nimitz. He spent a fair amount of time on the Nimitz watching flight ops (always volunteered to go over for supplies). He doesn't remember the exact numbers but thinks 57' sounds about right. He also said that it varied significantly depending on how many planes were on board (displacement).

He had no idea on the "bolter" question though.

per the site below, bolter is the 'go around' that happens when they miss the tail hook. Lots of other navy slang that might be useful, too.

Jim,

While this doesn't answer your question directly, I thought you might find this interesting - especially the section labeled "Night of the Pitching Decks"

57 Feet is close enough, give or take a couple (for variations in draft due to loading, as previously mentioned). Draft is normally 37 to 39 feet, and total height (light loaded) is 214 feet (includes all the antennae on top of the island).

For a quick comparison between US carriers (http://www.uscarrierhistory.com/charts/chart25.pdf)

For more information about requirements for parking one of these suckers, see: INTERIM TECHNICAL GUIDANCE (ITG) FACILITIES HOMEPORTING

In this photo (http://www.naval-technology.com/projects/nimitz/images/nimitz1.jpg)of a Nimitz-class carrier, the height from water line to flight deck is about 5.4% of the length of the flight deck. If the flight deck is 1092 feet, then that gives a height of 59 feet. So 57 sounds reasonable...

technical but wouldn't be good to write 'when they miss the tail hook'

what they miss is the arresting cable. The tail hook is attached to the plane.


They come in at full throttle as if they were taking off so that if they miss the cables they are right back in the air DAMNED FAST which is why the are called bolters.

You're right PSB, my excuse is that it was past my bed time ;)
