Why is cost a consideration ?
<<The Royal Navy and BAE Systems plc were pleased as punch yesterday to announce that their implementation of Windows for Submarines™ is complete ahead of schedule. Windows boxes on Ethernet LANs are now in control of the UK's nuclear-propelled and nuclear-armed warship fleet.
The programme is called Submarine Command System Next Generation (SMCS NG), and uses varying numbers of standard multifunction consoles with two LCD screens, hooked up on an internal Ethernet network installed on each sub. Initial reports as the programme developed suggested that the OS in question would be Windows 2000, but those who have worked on it have since informed the Reg that in fact it is mostly based on XP.
BAE and the Navy say the project has completed early, as many of the systems were installed extremely fast. The entire command system of HMS Vigilant, a Trident nuclear-missile submarine, was apparently replaced with the SMCS-NG Windows LAN in just 18 days, according to BAE. The use of commercial-off-the-shelf technology is expected to save the taxpayer as much as £22m in support costs over the next ten years - a bit more than £2m a year, or about a thousandth off Trident's running costs.
“This is a fantastic achievement," said Captain Pat O'Neill. "From speaking to operators and maintainers, I know how much they like SMCS NG. BAE Systems' work is proof that we can get commercial off the shelf technology to sea quickly and support it affordably."
Many in the software community have viewed the Royal Navy's wholesale move to Windows-based command systems with concern, feeling that the savings are not such as to justify possible losses in security, reliability and assurance. In addition to the existing nuclear submarine fleet, the RN will use similar equipment to handle its new Type 45 destroyers in combat, and versions of SMCS-NG will also lie at the core of the upcoming Astute-class subs.
Here on the Reg naval desk, we'd go relatively easy on submarine worries - even the Trident boats - as sub command LANs are by their nature very isolated and physically secure, and submarines almost never need to give their command systems autonomous firing authority.
By contrast, however, an air-defence destroyer like the Type 45 - if it is to be much use - will fairly often have to give its collection of Windows boxes the ability to loose off a sheaf of Aster missiles without human authorisation. Shooting down the possible supersonic sea-skimmers of tomorrow will be even more impossible with the delays of having humans in the loop.
Just to add to the slight feeling of nerves, a destroyer LAN will need to be connected to other networks off the ship as a matter of routine, and physical access to a destroyer is hugely easier than to a sub as well.
So we aren't really looking at Windows boxes triggering nuclear armageddon if something goes wrong here. But we just might, if things go wrong, be looking at a computer snag causing another USS Vincennes airliner shootdown disaster in coming years. Or, of course, at British sailors of the future staring helplessly at what would shortly be literally a blue screen of death, as the shipkillers bored in without response. ®>>
Terrific if the system works, as they then have a working model they
can use to leverage quality.
DOESN'T mean to say the BAE system has to be necessarily be used at sea.

Publicity is publicity M, whether it is bad publicity. A worser thing than being talked about is not being talked about.

With all these great things. What was so bad about the Nazi's?
Statements on the Internet on what the Nazis invented/ contributed to the modern world
Volkswagen
KdF
computer, invented by Konrad Zuse 1941.
Jet plane in 1939 by Heinkel Flugzeugwerke.
The first manned rocket flight in 1945 (unfortunately it lasted only some seconds and pilot Lothar Sieber died)
Nazi doctors, in line with their campaign for public health were the first to write a major scientific paper linking smoking with lung cancer, I believe smoking was even banned, for a brief time in the Luftwaffee.
Nazis invented Nerve gasses Sarin and Tabun.
Invented first effective automatic rifle, single person anti-tank weapons (precursors to RPGs).
You can see some magnificant architecture by Speer that was planned in nearly any documentary on the man.
Autobahns
Stealth technolgy was invented by the Horten brothers during the Reich.
Audio technology using magnetic tape was a Third Reich invention. Copying German tape recorders was how the famous American corporation Ampex got its start. Magnetic tape was also essential later for the video tape recorder. Allies hadn't a clue how the Axis was transmitting speeches and programs hours apart to different locations and having them sound "live." It was top of the list of technologies to capture as the war concluded.
Management systems for keeping massive and complex development programs on track was another "invention" transferred to the US, along with its scientists and project managers. These systems allowed the Germans to have developments underway in numerous categories and perform them remarkably well.
The Wankel engine, which is now referred to as the "rotary engine" was invented during the Third Reich. Mazda uses this engine extensively.
Someone mentioned the Autobahnen as really an idea thought up during the Weimar Republic. Yes, but that brings to light another achievement, and that is simply the will and energy to put unemployed workers to work doing things that needed to be done, something the Weimar government was totally inept at doing. "Parliamentary chaos" combined with acquiescence to WWI reparations were the problems.
Missile technology: Ground-to-ground, air-to-air, air-to-ground, ground-to-air, ship-to-ship, etc., using wire guidance, TV guidance, IR guidance (everything but laser quidance). Most of these missiles were not at the highest form of development, but their work launched and made a bundle of money later on for corporations like Boeing, Raytheon, Hughes Aircraft, North American Aviation (Rocketdyne Div.), etc. All of these companies had their German "Chief Scientist" heading up research and development operations.
The promising IR technologies were mostly all developed during the Third Reich. They had "night vision" devices while the Allies were still wondering if such things were possible.
Modern sewer treatment facilities are all derived from Third Reich technology. You've probably seen them with their settling ponds and huge skimmers.
While the Englishman, Farnsworth, gets credit for the invention of a very rudimentary television, it was the Third Reich that perfected television and conducted the first broadcasting.
Application of geophones for seismic wave detection was used for locating artillary.
The "wishbone cannon" was invented and installed at Calais, France. It was destroyed before it was operable.
The "rail gun" was another significant invention, which the US and SU copied. This weapon employes a series of ring magnets to propell a rail mounted projectile. The significant feature of this "gun" is that it can accelerate the projectile at a speed nearing infinity -- at least in theory. Conventional explosives are limited by their individual, finite rates of expansion and hence constrained in how fast they can make a projectile move.
The intial "invention" of the Third Reich that made everything possible was the breaking away from the international banking system, which made its money on debt finance; i.e., usury. This act was probably the most important event which caused WWII to later occur. In the Thirties the German economy was booming and all sorts of new humane benefits were granted to workers. Elsewhere, deep economic depression was underway, and Roosevelt, for instance, really couldn't get things to moving until we went into a war economy mode.
In all, 300,000 patents and copyrights were expropriated from Germany by the Allies after 1945.
The Fischer-Tropsch process to produce synthetic fuels from coal, which fueled Germany's armed forces throughout the war.

dave answers:
Yes, you're right about the inventions and all that stuff. What was bad about them was that they killed 6 million Jews and millions more who they didn't like, had horrible concentration camps where they would put them in gas chambers, had them dig their own graves, starve them to death, and also shot innocent men, women, children, and even babies. They were influenced by one of the most evil men in history, Adolf Hitler. So overall, they were still pretty bad people and there are still Nazis out there even today! So if you talk to people about them, they will still think of them as brutal and evil people. Know this though, not all Germans back then were Nazis. Interesting data you have there.
