A weapon ultimately can be used or not, whether it is good or not, and exactly how to use it, all need to be tested by war. The final outcome may not satisfy everyone or even most people.
In the history of humankind, many weapons have been created out of wishful thinking. Designers hoped these weapons would perform miracles on the battlefield, but in reality, they proved to be mistakes, things that should not have existed.
There were also weapons that existed in large numbers and were used extensively, but they were not necessarily outstanding. They had various problems that in some cases were never corrected.
Take, for example, the Bismarck battleship, whose anti-aircraft capability was terribly poor. If one speaks of its appearance, it surely ranks in the top three among battleships. But when it comes to technological level… Perhaps it was the strongest battleship of World War I during World War II?
