? I'm not sure you understand. The greatest pressure differential that will ever exist between the inside of the ship and the outside will be one atmosphere.

but when a breach makes an opening exposing liquid oxygen to outer space, the pressure is radically compromised and has no choice but to escape the container and the quickest way is to litterally rip out of the container in a matter of seconds.
You're being overly dramatic. The rate of loss of air will be dependent on the size of the hole and the pressure differential. The more air that is lost, the lower the rate of loss will become. A small hole will not result in very rapid loss. And the container would only be ripped apart if it had weak walls. I imagine that a spaceship would be built to survive breaches.

Having small leaks between compartment can only happen within a container having two compartments,
I'm not sure what your point is. You seem to be saying that you can only have leaks between compartments when you have more than one compartment.

but leaks going out to outerspace will result the total destruction of the container.
No. It is entirely possible to built a container that could take the pressure differential. A submarine with a small leak, even at high pressure, will not be destroyed, providing the hole is small enough. I use apparatus that create near-vacuum pressures at temperatures of around 1K. A leak would ruin the experiment and damage some of the equipment, but it wouldn't all be ripped apart.

Now, I'm not saying that you could have a leak the size of a pin on a NASA space shuttle to wreak a devastating result, I'm sure it would hold together, you would just have a super suction. But a breach doesn't need to be big, it just barely needs to be big enough depending how big the object is to do damage.
That's rather contrary to everything you were saying earlier. 'super suction' isn't a very quantitative term. A 1 atmosphere pressure differential on the other hand is.

Changes in pressure is too far greater, you would not even have time for it to freeze over to a solid matter. If what you say is true, how long would it take for oxygen to respond to solidifying in this dramatic change?
I'm not sure how long it would take. I just know that at the triple point, the melting and boiling temperatures are the same at zero pressure. If the temperature is below the triple point, the substance will be solid. If it is above, it will be a gas. Any heat the substance has will have to be radiated off, since there's no air for it to be lost any other way, therefore it would take a while for a substance to cool down. But cool down it would do and freeze.

For the most part though, I was just using "radar" as a generic term. It sounds better than saying "those little blips on the screen" even though it's not technically accurate. I was also just paraphrasing some things but I guess that's not exactly a good idea when you're trying to give more details to something. So now, correct me if I'm wrong but aircraft generally use several types of "radar" - a couple for ground and a couple for air. Each has their own level of signal strength that determines how easily they're seen by other systems. Using FLIR is more "passive" than using an "active" form of radar as it emits a lower signal making it more difficult to detect. Which then again depends on the angle and strength of the FLIR. And yes, submarines use passive sonar as well but this too is limited to the front and sides of the ship - hence the need for a towed array which is only useful at low speeds. I guess it would have been more appropriate to say that active sonar is a nearly 360 sonar system while passive is more restricted. Why I brought up passive systems like sonar I don't know since they'd be useless in space. I guess I was just trying to demonstrate that we adapt systems for the environment.
