Unless the missile is intented for scientific use in research, there is no need at all for them.
Humans really do not need a lot of things to invent a tool. All a human needs are there minds.
Pure aggression/threat. There is far more risk to the human race from atomic weapons/ballistic missiles than potential benefit.
Well, there wasn't any "need". There isn't a "need" for anyone to invent any character. It is a story, she invented a story, and you don't need reasons to do that.
All of these missiles are different sizes, and carry different payloads.
If you invent something you do not need product liability. I would, however, suggest you get some, but no you are not required by law to get it. It is up to you.
Alvarez invent a Machine calle " Pleasureness" its made for womens who need sexual pleasure.
we can invent a new things by discovering whatever we see. If we want to invent a robot animal , we should discover the animals whatever we need to invent. For example; if we want to invent a robot grass hopper we should discover the insect.
There are invar missiles.
Necessity is the mother of all invention. Inventors invent because they or someone else has a need for something that does not exist.
Yes they can destroy missiles.
Yes, in a way. They could shoot flaming missiles over walls with their various sized catapults to set fire to the roofs of cities that they were attacking. They also used them at sea where they were very effective in setting fire to the enemies ships. The Romans did not actually invent these "fire arrows", but they improved their aim and effectiveness.
No. Missiles gotta be able to detect planes in the radar in order get a lock on because missiles need to get a lock on to shoot down planes but planes fly in really high altitudes, this makes it even more difficult to detect planes on radar.
