Hi dunmunro, It's very difficult to find good information on those radars that is also based on solid sources. I tend to have little faith in internet sourced material as well. A good study could be done, but it hasn't been done that I'm aware of. It should be done. From the few words given by a few...

CXAM, SC and SK These are all based on the same basic 1.5 meter wave length radar system design. These radars were built by RCA based on a prototype developed by the Naval Research Lab called the XAF. The XAF was first tested in early 1939, and the Navy was jazzed that it could track shells in flig...

Type 279 The first radar used on Royal Navy warships was Type 79 with the first sea trials conducted in early 1939. It operated on a wave length of 7.5 meters. Type 279 was an improved version. The antennas consisted of a send antenna, and receive antenna, each placed at the mast head of the forema...

The role of private industry was indeed much more prominate in Germany than in most other nations. For example, radar was centered in the private and competing companies of Telefunken, Lorenz, and GEMA. Military agencies such as the NVA and Sonder Kommision-Radar (actually consisting of scientists f...

Heye was a member of Raeder's staff and also a member of the committee that was fleshing out the Z-Plan. As Thomas has written, Heye made a draft that criticized the Z-Plan as unfeasable. He was also asked to come up with a set of general specifications for the planned warships. Heye sought the expe...

The Battle of the Atlantic was orders of magnatude greater in scale and intensity compared to these other submarine campaigns. Based on post war evaluations of records, U-boats sank 7.8 million tons of shipping in 1942 alone. This was greater than the Japanese total merchant marine losses. Usually a...

Here's some data on USN sub ops in the the Pacific. A report called JANAC was completed in 1947, although it was accepted that confirming all the claims and coming up with precise data would be impossible. Part of the problem was that many Japanese records needed for comparison were poorly kept or w...

Rohwer's data suggests that 630 U-boats were lost in actual combat operations vs Allied shipping. 123 were lost at base or home waters to enemy air raids, mines, and accidents. That's 753, or very close to Jose's result. 11 were captured by the enemy or interned in neutral harbors. 153 were surender...

It would be interesting to compare the U-boat losses/Allied ships sunk with the US subs lost/Jap ships sunk in the Pacific..... It's difficult to make that an apples to apples comparison, because the IJN was not really interested in anti-submarine warfare, and when they did reluctantly attempt ASW,...

Very good! Have you seen Jurgen Rohwer's data? Rohwer breaks down losses into sub- catagories, such as where the losses occured and what the U-boat was doing. As your data suggests, losses started to spike in May 1943. This was the time when the Allies began equiping patrol bombers with radars that ...

Karl, Germany was up against it not only because of the number of Allies arrayed against, but also because it could in no way match the industrial capacity of the United States. The US out produced the combined Axis many times over by itself. German industrial capacity could not keep up. This was ev...

Another flaw that I may add, is the lack of adequate RADAR. This was not necesarily a design flaw more than a cosmetic and strategic one. This was not necesarily their fault, but im sure that better sets would have been created later in the war But don't forget that the Reichsmarine knew about rada...

The 55 mph speed limit was just silly. In fact on some roads sections out in the vast west of the USA, any speed limit is silly. In many cases driving slower doesn't save fuel either. What was supposed to be a temporary measure turned into a rediculous, unpopular, and unenforcable, albastross lastin...

The rights of States and those of the Federal Gov are ambigious, and probably intentionally so. This allows difficult issues to be haggled out on a case by case basis. The courts have had to deal with such issues for 220 years. The Interstate Commerce Clause of the Constitution gives the Federal Gov...

RF, Your quite correct that there is a fundamental difference between how the American founding fathers and framers of the US Constitution define rights, and how rights are defined in most other democracies. In America the rights and liberties of the individual are paramount. Central to the American...
