Having worked on that class of ship (LBNSY was the Planning Yard) I generally knew the answers but couldn't remember the specific ID numbers of the equipment. We were more concerned with the superstructure cracking and the ships getting too heavy where the toilet drains were underwater and making them Stealthy as well.

So I googled the answers for the correct numbers:

PERRY-class ships were produced in two variants, known as "short-hull" and "long-hull", with the later variant being eight feet longer than the short-hull version. The long-hull ships [FFG 8, 28, 29, 32, 33, 36-61] carry the SH-60B LAMPS III helicopters, while the short-hull units carry the less-capable SH-2G.

The units with long hulls (FFG 7, 8, 15, 28, 29, 32, 36-61) were to have had the sonar suite upgraded to SQQ-89(V)2, with SQS-56 hull sonar retained,


As further information, LBNSY did not develop the hull lengthening drawings. It was done under contract for NAVSEA by Bath Shipbuilding. However, we were working on another hull modification.

We did develop the drawings for repairs of the cracked superstructures, the reinforcement strips (that saved the Roberts from cracking in two) and the ballasting while moving the waste drains on up.

In my above post answering the question on long hull FFG-7s, I mentioned we were working on another hull modification. This was not the hull strengthening shipalt but something entirely different.

It also had to do with the back end of the ship and studies were considering the Perry's but the first design was developed for the Spruances.

Was war es?

RAM ?

That was not a hull modification. Though we were studying RAM for the Figs.

Look for my hint in the question.

I do remember working on the Wadsworth in DD2 in the mid to late 80's when they said they were putting on thrusters. I haven't seen or heard any mention of those being on ships, and I didn't bother to go under the ship to look back then.

RustyBattleship

Well, I can't hold my breath that long either. But it was not thrusters though up forward they did have --- hmmm --- maybe another question lurking there.
At least on the FFGs.

And plans WERE drawn for a 963 class ship.

So, what's the answer again?

RustyBattleship

You want an answer already?

Okay. Just finished some rough sketches on Corel Draw 8, exported them to a JPEG so it can be read by Adobe Photoshop and have the contrast corrected.

THIS was AFTER I had brought my blood pressure back down from 2 hours at COSTCO and before that several rounds with AT&T (No gloves) about their sudden increase in prices. But that's for another thread.

The answer is:

Now hang on guys,

A design the Germans came out with in WW II.

The STEPPED STERN. And we did install it on at least one Spruance but not here in Long Beach.

OH DUH!!!! I, like, totally knew that!!! LOL

Don't feel bad. I wasn't in on the design phase that much. Jim Morrison was our structural engineer and project leader on that one. We discussed the design among each other and I looked over some of his drawings, but that was about it. Then one of our draftsmen, Lee Upshaw (who owns The Scale Shipyard that builds fiberglass hulls for model builders) just off the cuff mentioned what class of German Zestroyer used that hull design. I think he even has a mold for it.

After the shipyard closed, Jim did not transfer to another government design agency. Instead he went on to become a Christian Minister.

RustyBattleship

Oh. Lee Upshaw just IM'd me and corrected me in that it was a WEDGE hull rather than a STEPPED hull.

RAL's_pal?

You wouldn't have to if you waited until they pumped the water out of the dry dock.


I thought Jim Morrison was filpping burgers at the same Burger King Elvis worked at. Actually they both reached the age of retirement by now.

I guess since nobody could answer my last question, I have to ask another.

When the USS Roberts (FFG 58) hit an Iranian free floating mine (of Korean manufacture copying an American design) it blasted through the Auxiliary Machinery Room and broke the hull nearly in two. The break was so severe, it could not run it's main turbines for the propeller to back out of the minefield.

Other ships offered to come in and tow Roberts out of the field but the Captain waived them off. After all, it wasn't until AFTER he realized he was in a mine field and was trying to back out through his own wake that a free floater drifted in and blew his hull open.

The reinforcement shipalt we added to the Roberts helped save the ship from breaking into two pieces. That reinforcement consisted of doubler plates along the top of the sheer strake, along the top of the bilge strake and on both sides of the flat keel.

But the Roberts backed herself out all by her lonesome.

How?

Ahh had to do some research, I learned alot. Seems they used thier nifty auxiliary thrusters to back off.

Lots of cool pics of the ship i found as well.

BINGO!
Actually the name was Auxiliary Propulsion Units or APUs. There are two of them, on on each side of the keel. They were originally intended to provide side bow thruster power for docking without a tug. But since they could be turned to face rearward, the skipper used them to back out of the minefield.

Your turn.
