Within this Document are the complete Readouts for METAL GEAR REX  .

The Metal Gear is outfitted with a Sensor Array, 3 Machine guns, 4 missile launchers and a Rail gun.

 Rail Gun                                                                    

Although conceptually simple, the operation of a railgun involves several problems that have to this day made a practical design (one that can be employed in the field in order to replace conventional weapons) impossible.

A wire carrying an electrical current, when in a magnetic field, experiences a force perpendicular to the direction of the current and the direction of the magnetic field. This is the principle behind the operation of an electric motor, where fixed magnets create a magnetic field, and a coil of wire is carried upon a shaft that is free to rotate. When electricity is applied to the coil of wire, a current flows causing it to experience a force due to the magnetic field. The wires of the coil are arranged such that all the forces on the wires act to make the shaft rotate, and so the motor runs.

A railgun is even simpler than a motor. It consists of two parallel metal rails (hence the name) connected to an electrical power supply. When a conductive projectile is inserted between the rails (from the end connected to the power supply), it completes the circuit. Electrical current runs from the positive terminal of the power supply up the positive rail, across the projectile, and down the negative rail back to the power supply again.

This flow of current makes the railgun act like an electromagnet, creating a powerful magnetic field in the region of the rails up to the position of the projectile. In accordance with the right-hand rule, the created magnetic field circulates around each conductor. Since the current flows in opposite direction along each rail, the net magnetic field between the rails (B) is directed vertically. In combination with the current (I) flowing across the projectile, this produces a Lorentz force which accelerates the projectile along the rails. There are also forces acting on the rails attempting to push them apart, but since the rails are firmly mounted they cannot move. The projectile is able to slide up the rails away from the end with the power supply.

If a very large power supply providing a million amperes or so of current is used, then the force on the projectile will be tremendous, and by the time it leaves the ends of the rails it can be travelling at many kilometres per second. 20 kilometers per second has been achieved with small projectiles explosively injected into the railgun.

Although these speeds are theoretically possible, the heat generated from the propulsion of the object is enough to rapidly erode the rails. Such a railgun would require frequent replacement of the rails, or using a heat resistant material that would be conductive enough to produce the same effect.

The complexity in railgun design comes from:

1. The need for strong conductive materials with which to build the rails and projectiles; the rails need to survive the violence of an accelerating projectile, and heating due to the large currents and friction involved. The force exerted on the rails consists of a recoil force - equal and opposite to the force propelling the projectile, but along the length of the rails (which is their strongest axis) - and a sideways force caused by the rails being pushed by the magnetic field, just as the projectile is. The rails need to survive this without bending, and must be very securely mounted.
2. Power supply design. The power supply must be able to deliver large currents, with both capacitors and compulsators being common.
3. Electromechanical design. The rails need to withstand enormous repulsive forces during firing, and these forces will tend to push them apart and away from the projectile. As rail/projectile clearances increase arcing develops which causes rapid vaporization and extensive damage to the rail surfaces and the insulator surfaces. This limits most research railguns to one shot per service interval.

While some have speculated that there are fundamental limits to the exit velocity due to the inductance of the system, and in particular the rails, the United States government has made significant progress in railgun design, and has recently floated designs of a railgun that would be used on a naval vessel. The designs for the naval vessels, however, are limited by their required power usages for the magnets in the railguns. These limits are larger than currently attainable and do reduce the usefulness of the concept for space travel and military uses.   In Sense it is possible to Fire a Nuclear Rocket within a  344 Mile Radius (Like the other Smart Gear)  But the rocket would not/ Could not fire massive rockets like The Shagohod.

But The Metal Gear Rex’s Sensor array is better than its Brothers and Predessesors.

Sensor Cone

A thermistor is a type of resistor used to measure temperature changes, relying on the change in its resistance with changing temperature. Thermistor is a portmanteau of the words thermal and resistor.

If we assume that the relationship between resistance and temperature is linear (i.e. we make a first-order approximation), then we can say that:

ΔR = kΔT

where

ΔR = change in resistance

ΔT = change in temperature

k = first-order temperature coefficient of resistance

Thermistors can be classified into two types depending on the sign of k. If k is positive, the resistance increases with increasing temperature, and the device is called a positive temperature coefficient (PTC) thermistor, posistor. If k is negative, the resistance decreases with increasing temperature, and the device is called a negative temperature coefficient (NTC) thermistor. Resistors that are not thermistors are designed to have the smallest possible k, so that their resistance remains almost constant over a wide temperature range.   The Metal Gear REX’s Legs are much more heavily armored Then the other Metal Gears. And have reinforced Dura Steel and Spikes that are used with mining Drills.                                                                                                                                                                                      

Defense Summary.

 The Metal Gear REX has near-impregnable compound armor, a pair of vulcan cannons, anti-tank missiles, and a free-electron laser, to protect itself from conventional forces. Its primary weapon, however, is a magnetic railgun capable of delivering an untraceable nuclear warhead anywhere in the world, without the propellant trail or launch flare that gives away the launch position of a traditional ballistic missile. Because of its sealed, one-man cockpit and thick armor, its sensors are concentrated in a radome on the left side of its body; this radome is very vulnerable to attack, and destroying it effectively blinds the REX, forcing the cockpit to open. In this state, the REX is vulnerable as its controls can be easily destroyed (In Metal Gear Solid, its designer, Dr. Hal Emmerich, states that this was intentional, declaring that nothing can be complete without a "character flaw").
