Army Transportation. Part-Two.

Modern Commercial Transportation.

Over the last twenty years or so many nations are now opting for civilian commercial transporters over that of their own military equivalents. This is because of two key factors cost and civil disguise in the upsurge of International terrorism.

Many other areas such as training demand the continuation of the usage as these dedicated vehicles, while many age quickly and are sold off from various arms dumps around the world. Some vehicles go overseas to continue in this role, while others are painted in commercial colours and schemes and continue in that disguise.

Heavy lifting of the Main Battle Tank was the initial role for the military transport, while also other vehicles have been designed for recovery or heavy vehicles themselves. The United States, Canada, Russia, China, India and Brazil, Australia still maintain a dedicated military fleets, because of the expanse of their less populated land mass.

There are many other types of Amphibious landing tracked vehicles such as the U.S. LVTP's, large Armoured Personnel  carriers and Surface to Air missile platforms that need to be moved over shorter distances that either their own power or that of the use of the Lockheed C-5 Galaxy, C-130J Hercules, Airbus A400M, Russian Antonov An-22, 124 Ruslan and Ilyushin Il-76TDM. Embraer KC-90 transport aircraft.

The Typhoon Class.

Worlds largest Submarine.

Soviet Russia was one of the most ambitious nations in the history of the world, especially in the last one-hundred years of civil engineering and the invention of machines. They launched the Space race with the Sputnik and Gagarin and by their fall they had the largest aircraft ever built the Antonov An-224 Miry (Dream), the Buran Robotic Space Shuttle and the elusive Typhoon Class Submarine.

After the fall of Communism came the dismantling of the largest stockpile of nuclear weapons on both sides and there were many cutbacks of fighter bombers and submarines, and other military equipment. 

It is not known, if all as claimed how much was actually cut back, because today it is estimated by N.A.T.O. that Russia is as mighty as it ever was!

The Typhoon was designed to carry the largest number of multiple Inter-continental ballistic missiles that was possible to get on a (36) Submarine, meanwhile each missile was capable of having 12 to 16 warheads!

It was also the first of a new generation of robotic operated systems, with less crew (125) than would be required normally. 

Russia like many nations had discovered that the submarine was one of the most effective weapon systems to have, because they can go undetected for months under the sea.

Interstellar Travel. Part-One.

Our nearest Neighbour.

Much of space science is currently being employed into the idea of sending a Laser powered sail spacecraft on a thirty year trip to our nearest neighbouring star, which is four light-years away. With our current technology it would take us two hundred years plus to get there and back.

At this time the only manned Space ship is the International Space Station, which is three-hundred miles up making a 45-minute circle of the Earth. The Russian Progress robotic and U.S. Dragon supply vessels are the only way of getting up and down, since the retirement of the ageing former Space Shuttles.

The next objective in to get a manned mission to Mars by 2035 or establish a southern-hemisphere Moon base, as a first step by 2028?

Prof. Stephen Hawking's is very keen to encourage the Solar sail project, but some believe it would be wise to test it out first within the known confines of the solar system? making a four hour journey to Pluto, instead of the ten years it took the New Horizon probe. 

It also remains unclear what is beyond Pluto in the Kuiper belt, which the second phase of the New Horizons will arrive at in 2019. One of the six believed moon type objects has already been spotted and a new planet Niku is on a 110 degrees plane between Neptune and Pluto. Meanwhile this small world is blue and is travelling backwards to the normal pattern of all the other planets rotation around the Sun.

The problems with Interstellar travel is the possibility of another rocky domain well beyond the Kuiper Belt that would be like a mine field to exit the Solar system, there is also believed to be another planet known as X9 somewhere out there with a very large gravity field?

Engineering, Maintanance and Building. Part-Two.

Differing Requirements?

Because there are so many different gauges around the world and types of systems from mainline, to metro and tubes there is need for the same types doing the same jobs at differing scales. This has been tried on the London Underground, who purchased smaller Class 66 locomotives.

In days gone by steam cranes and open waggons carried material and crew gangs to build, but today a whole section can be laid by machine as we have already seen. It is the complex electrics overhead that cause expense and delays, computer systems have to be accurate with signal commands.

This new requirement when in place allows high-Speed travel and less point switching for passenger trains, but freight remains a different matter. Most recovery over the last forty years has been carried out by a second locomotive, but in the years to come this with under floor motors as on both tube and metro stock will overcome all of the old problems.

Much of the maintenance of the old days may be carried out more by robotic controlled vehicle based on the current stock with video equipment. Not every nation will be able to afford this so depending on where they are many older methods will remain.
