Heres an easy one,which was the first battleship to use steel as the main building material?

Tin Man

France`s Redoutable (1876), first (mostly steel) battleship, the Le Gloire, first Iron clad 1859.

Sorry for the late reply,lost track of the thread,question all yours of course,the Redoubtable was what I was looking for

Tin Man

Cheers mate.
Ok, a two part question. Which USN Carrier featured in the Star Trek movie "Star Trek IV, The Voyage Home", with scenes filmed on board. This carrier also featured in Top Gun, with scenes filmed on board It also starred in another naval-centric 1980 film, which film?

That is so easy for me I am laughing. The USS Ranger (CV-61) was the stand-in for the Enterprise in the movie. You will notice that they set the actors up in such a way as you could not see the bow number or the Island on the Flight Deck. If they did, you might have seen a polemast I designed for the ship.

Unfortunately she was inactivated in 1993 and I was tasked as project leader to design her towing rig and monitor stowage of all topside materials down on the hangar deck.

Her last claim to fame was in April of 1992 when, in commemoration of the Doolittle Raid on Japan, two B-25 Bombers took off from her flight deck in San Diego harbor. At least these bombers, "Heavenly Body" and "In the Mood", were not loaded up and had a few hundred more feet of "runway".

On the upper left hand corner of the picture you can see my polemast that supported the fan wire antennas from the yardarm. The bottom part of the mast is a steel tube welded to the superstructure. The upper part of the mast is aluminum. And they are NOT riveted or bolted together but WELDED together.

Oh. The other film was about the Nimitz going back into time just before the Pearl Harbor attack, "The Final Countdown."

Trivia: She also carried a fiberglass white horse on board and when coming into port they would have it on one of the elevators with a crewman mounted on it and dressed up as the Lone Ranger.

One more thing. I've been asked to conduct an inspection of her later this year. So any photos you have of her, upload them to dreadnght@aol.com.

Well, Rusty`, just my luck! Wonder why Ranger got all of the hot jobs and cinematic opportunities, albeit representing Enterprise!

Welding steel to Al, that`s impressive too, tried it on several occasions when I shouldn`t have really, failing miserably! How did you manage it? Laser brazing?
They can do it without using any flux at all now. Or GMAW?

Hey Rusty, did you get those Bremerton pics I sent you?

No I haven't. Waiting with baited breath (darn sardines) for them.

The trick is to slip a 1 1/4 inch thick plate of BI-METAL in between. The top is aluminum and the bottom is steel. They are fused together with Ammonium Nitrate high explosives. The explosive is on top and the ignition started in one corner. There is a slight gap between the aluminum and the steel. As the explosion moves toward the other corner, the two metals create a sheet of Plasma shooting out the same direction as the explosion. This Plasma sheet not only fuses the two metals together by heat, but actually creates ripples in their surfaces that hook together like Velcro. So it is mechanically bonded as well as heat bonded.

Today, all aluminum structures attached to steel decks of ships use a strip of this metal welded to a steel coaming on deck and you can weld the aluminum deckhouse to it. There is a MIL-SPEC on it called Bi-Metallic joint. Commercially it was invented by DuPont and is also known as Data Clad.

It must work as (according to my personal log book) I issued the Pole Mast plan for the Ranger on August 3, 1973.

Tin Man

Ahh, Rusty`, you have described explosive welding of dissimilar metals using a transition piece, that bi-metallic joint. We can do it today using specialised laser brazing, with an Aluminium based wire filler, even without a flux or transition joint, but your method is much more traditional.

GMAW can achieve good results too. I had a welder who could weld just about anything together, its a great skill.

I guess it's my turn to ask a question. Since the previous question had to do with movies, this one, or two, or three will also.

Richard Widmark and Sidney Poitier starred in a movie about an American Destroyer hunting for Soviet submarines in the North Sea.

1. What was the name of the movie?

2. Who played the SONAR operator and what role on TV was he most famous for?

3. What scene in the movie bowled over everybody so much that was so inclusive and so accurate that an investigation was launched to find a security leak?

4. What was the hull number painted on the bow of the ship?

5. Based upon that number, what Destroyer probably played that role with a simple addition of one number? It could have been another ship of the same class but with a slightly different hull number. So I'll take the names of either or both ships.
STRIKE THIS QUESTION. MY ERROR. I THOUGHT IT WAS A SHIP I WORKED ON BUT RESEARCH SHOWED IT WASN'T.

6. What technical error was made in the underwater scenes of the Destroyer navigating among the ice floes?

7. Of the actor who played the weapons officer, what was the name of a famous relative of his?

Okay. So beat me with a wet noodle. That's SEVEN questions. But all of ONE movie. As a matter of fact, when it played on TV, we (in the Design Division) were all highly advised to watch it and have a discussion about it the next morning.
CORRECTION: ONLY 6 QUESTIONS AS NUMBER 5 IS STRIKEN.

Knaur Amarsh

1.The Bedford Incident
2.Wally Cox, Mr. Peepers
3.Maybe the scene where the lab tech examines the scraps from the garbage to determine the proximity of the sub?
4.DLG-113
6.Not sure but perhaps the general implausability of events.....a submarine wouldnt have so much oxygen that they can keep tracking it for so long
7.Charles McArthur?
