Oh dear little boy why did you now say that in the first place instead of resorting to immature and nasty swear word's like an illiterate person.
Vectoring as you know is all about direction when talking about a projectile or an Aeroplane (Sorry that's the older and actually correct spelling
it's a French word and they invented though some time in the teen's of the last century it became standardized in English speaking nations to the
Americanization of Air Plane).
So how do you change the vector of an object moving at extreme speed when you can not use a physical barrel to do so as in the case of a huge rail
gun the air has been removed and once it reaches a significant speed the barrel is removed and a set of magnetic ring's are used to accelerate the
projectile at ever increasing velocity's.
Well you do it to make it rather coarse and easy for you to understand in a way that is very similar to how they do it in a particle accelerator or
an even easier analogy how they were able to control the direction of electron's streaming from the electron gun's in an old cathode ray tube.
Now this is a vast over simplification but I have to simplify it for you now don't I, there are two ways' of doing this, one is for the final stages
of the acceleration track (there is no actual track it is just called that though there is an electromagnetic assisted lift system) of the rail gun,
this can be done by using yet more magnet's, these very powerful high speed electromagnets can then BEND the path of the projectile in it's final
stage and precisely target it onto it's assigned flight path.
Now let's just clear some thing's up for you about ballast, most ship's are displacement hulled vessel's and what this mean's is that they move
THROUGH the water, now ballast is essential to control the trim of a vessel especially in modern container ships so that asymmetric load displacements
can be compensated for and regulated by moving that ballast around and also for when the ship has no cargo which in most cases with displacement hull
container ship's would mean that the vessel would then ride too high in the water and lose some measure of stability giving it a tendency to roll
across it's beam so to compensate the cock's are opened and the sea water is pumped into the ballast tank's so making the vessel more stable in the
In the case of most modern warship's however there hull's are a hybrid between a displacement and a planing hull.
What is a planing hull, well the first military vessels to use it in modern time's were actually small RAF - not Royal Navy - speed boats designed to
save downed pilot's as the cold waters around the English coast make time an essential factor in getting a pilot out of the water as fast as possible
and a certain very famous guy you may better know as Lawrence of Arabia was very instrumental in there adoption but the knowledge of them goes much
further back in time.
The oldest SEMI planing hull we know of is that of the old viking long ship's, it worked like this a planing hull rides OVER the water and in the
case of the long ship's they were made with overlapping plant's, the upper plank over lapped the lower plank and this in turn created channels along
which as the hull moved through the water as it picked up speed air became trapped along these grooves and this in turn reduced friction upon the hull
allowing the viking ship's to move much faster than they would have been able to do if they had not had that overlapping plank design.
Since the test rail gun was fitted along the length of the destroyers hull to alter the elevation all they had to do was shift ballast for to aft and
aft to for and to alter the ship's pitch as you call it that would have been by adjusting ballast across the beam of the ship, of course it was NOT a
weapon just a development stage prototype that was RUMORED to have existed, I even knew the name of the ship but it eludes me these day's as I only
read about it, the story as best I can relay it was this and it was very scant on technical detail's, back in the 80's the US navy apparently took one
of it's older destroyers, a large ship and used it for testing and in this case it was fitted with a prototype rail gun testing rig that ran the
length of almost the entire hull, it was not a deploy-able weapon but development prototype so this was just to prove the concept or a mobile ship
mounted rail gun based weapon system and was apparently a failure but proved that it was at least possible so the US then can onside with the we Brits
in developing better modern rail gun's, this was fairly early day's but as you MAY or may not know the whole rail gun concept is actually a very old
Early experiments in rail gun's were less than impressive and are based on the mid 19th century invention of the Coil Gun an early electromagnetic
weapon that was too far ahead of the technology of it's time to ever have been developed that early.
The first what we might call a rail gun was created by a french guy at the start of the 20th century.
But these day's even India is in on the game having developed there own and it is promising as well if likely very far behind what we have here and
likely with the help of Indian scientists that probably worked on our own project's or knew some guy('s) that did or perhaps we leaked it to them to
keep the region stable by giving a counterbalance to China.
(by the way I know you are just as clever but you started it with the foul language so you know you asked for it).
