And Katyusha of the Soviet Union

During the war, Germany had more than 20 epoch-making scientific and technological achievements in the field of weapons, while the United States had only two, and the United Kingdom and the Soviet Union had one. After reading it, I unconsciously counted. The two items of the United States should be atomic bombs and wireless near-blasting fuses. The British should be radars. The Soviets couldn't remember it. It was T-34? Katyusha?

Later, I counted the Germans' advanced designs in weapon technology, but they didn't count to 20. Who will make up the numbers?

This is what I can think of:

1,V-2: The earliest ballistic ground-to-ground missile;

2,V-1: The earliest **;

3, ME-262: The first practical jet fighter;

4, MG-42: The first universal machine gun;

5, S**/MP-44: The first type of assault rifle;

6. Fritz X: the first guided bomb;

7, HS-293: The first anti-ship missile, the first air-to-surface missile, and one of which is a TV guide type, which can also be considered the first;

8,X-4: The first air-to-air missile;

9,X-7: Does the first anti-tank missile, but it has not been put into practical use, does it count?

10. Rhine's daughter: Does the first type of air defense missile not put into practical use?

11. The earliest magnetic mine, forgot the model;

12. The earliest sound guided torpedo, forgot the model;

13. Dula train cannon: the largest artillery in the world;

14. Tiger tank: In which aspect can this guy be considered the world's number one?

15. Submarine: The first type of submarine that does not rely on air? Or is it an "electric shark", which can be considered the world's number one?

16. There is also a front swept-wing bomber. I forgot the model and think it is definitely the world's number one. Anyway, it has not been practical yet!

17, Ar-234: The first type of jet bomber, and it was also the only jet bomber in World War II;
Chapter completed!
