I'm watching aliens on TV and Ripley just activated the self destruct system.

It seems that plot line has been played out in Star Wars (at least 3 times, between the show and the movies) and innumerable other sci-fi stories.

But why do all these ships have self destruct systems? Does the USNavy equip it's aircraft carriers with a button that will blow it up on command?

A little help please.

to add the ability to get a new star ship in all of the damn star trek movies, duh

To rid the Klingons on Uranus

because it accounts for interesting plots.

Don't U.S. military vessels have protocols for destroying sensitive technology and information if capture is imminent?

This is just a more efficient and faster wayt to do the same thing - and maybe in the future there's a greater chance of alien capture or a greater risk of technology falling into the wrong hands.

... yes, I'm a nerd.

In case I get aboard!

To suck some poor smuck in to the heart of the ship to get killed or traped so that the movie last longer.

Its called a "range safety device". Get with the program.
Also, you cant be evil unless you have one.

I would think that it would be there to make sure sensitive technology is destroyed, and so that it burns up uniformly on reentry should it fall out of orbit.

Because it's a convenient plot device.

It's like scuttling on the ocean, but in space there's no where to sink to so you have to blow it
it's been a while since I've seen it but in Alien was it an actual self destruct or was it more a case of disabling something that prevented the engines from overloading?

It's called scuttling, it was done on the seas for years during times of war, but its hard to sink a ship in space!

In the case of the Nostromo the self destruct involved disengaging the engine cooling system, causing an overload. Given the size and mass of the vessel and ore processing facility (that of a small asteroid) having something that large go rogue could be a huge hazard to other ships and planets.

For Federation Starships too much military tech and info to fall into enemy hands. Primary self destruct is via the anti-matter storage cells. Drop the containment on them or the M/AM reactor and you'll get a VERY big bang. Secondary self-destruct is via charges placed throughout the ship (see Star Trek III: The search for Spock).

For small, non military ships the only reason for having self-destruct is simply as a plot tool.

I'm not allowed to tell why.

and if it hadn't fallen into the genesis planet there would have been a lot of ship left over

You mean Star Trek.

the real question is though,why does an ar have a self destruct mech when bumpfired underwater

April 1, 2001 - A US EP-3E surveillance plane collided with a chineese jet. It barely made it to china for an emergency landing.

While the pilot was trying to land the plane, the crew was busy trashing the electronics onboard per their orders.

'Self destruct' is just a fancy way from keeping the enemy from gathering intelligence, technology, and possible a weapon that can be used against you.

As for the answer to your question it's 42. Oh wait, wrong question.

Having a self-destruct mechanism allows the engineering crew to reverse the polarity whenever they need to. Have you tried to reverse the polarity on your laptop computer, cell phone, car? It doesn't work...you'll fry them right up. But....if they had been properly fit with a self destruct device, you could reverse the polarity all day long like when you needed to create tachyon beams and such.

Of course, if you set up your electronics that way, you'll have to also remove any fuses/jumpers out of the system, and install high-voltage lines right under the control panel to blow up in your face.

So you can kill a bunch of Klingons when they beam over, then you have to figure out how to work thier ship. :-)
