Awhile back I was in a discussion with a forum member about gyros, and I remember saying the old gyros used on US Navy vessels were the size of rooms (I think I was conservative in my description). Considering a gyro now takes up less than .5" sqr, We can really see how times have changed.

Surprisingly, technology is slow coming to US vessels, the photo's below were from 1917, the ships of the 70's and 80's had not changed much. I hope they have now, however... :)
Old ship gyro photo can be seen in this link.

USN Ships--USS Henderson (Transport # 1) -- Construction.

Yes much smaller than a room and also much before the aforementioned time period... :)

That 1917 model sure was big though wasn't it?

hi Mike,
I 'think' you are confusing a ships 'mass stabiliser' with a 'positional stabiliser gyro' system.:)

Yeah, that thing physically stopped the ship from tilting in the waves.

The drift on SEMS and mini gyro's is laughable compared to what the Navy uses.

They have big stabalizers in tall buildings, Just a big mass suspended and acts like a dampner.

Tuned mass damper. Acts like a snubber circuit.

I guess shipbuilders should spy a bit in aircraft development. Using small size gyros the accuracy won't be less if the second part "Fly by wire" is engaged. :)

Ships don't need gyros anymore... those 3 Navy SEAL sharpshooters proved a bobbing ship isn't an obstacle of sorts!!

Love to know how they managed that. The whole thing's going to make a good movie.

HiTech. I'll bet you money Navy ships still have gyros of some type. There's NO WAY the military would rely on GPS only. In the case of a bad solar flare the entire naval fleet would be adrift at sea.

Did I miss something in this thread? 3 Navy seal snipers what where?

Wow, I'd heard about them, didn't realize they'd got em back. Those must have been damn good snipers.

I wonder if the Navy will have to start escorting our merchant vessels. Considering the threats the pirates made.

If their smart they wont escort any. They will put actual merchant ships out with fully armed navy seal teams possing as the crew. :eek::D

would you still want to be a pirate after running across one of those ships?
Assuming your not dead of course!:D

I doubt that would happen. The Seal community is rather small ~2500. Maybe it is due to global warming... ;)

Three dead pirates and one in custody will send a very strong message.

Even at a mere 25 yds. using trained sharpshooters, I find it difficult to believe that they could effectively put lethal rounds in the correct targets, during the night, using night-vision scopes, through a small window, in a bobbing lifeboat! I think it's more a propaganda tactic for PR purposes. It wouldn't surprise me if SEALS were in the water next to the boat using percussion grenades or similar disorienting tactics. Their actual method of attack is likely classified and what the public has been told could be quite different than what actually occurred. The Maersk captain may be under a gag order regarding the specifics of the rescue. Then there's always the minute chance that the event unfolded exactly as published. What's important here is the fact that the American hostage was rescued, and the perpetrators are dead (except for the surrenderer) sending a clear message to others of what awaits them if they choose to behave in that fashion.

Me too. More to this story. I was thinking more along the lines of a stable weapons platform.
