  1. 1. Nuclear – David sized, Giant force " Veikkaus Football Betting: David & Goliath"
  2. 2. 無限制潛艇戰 (Unrestricted submarine warfare) • In the early stages of the war, the U-boats (Untersee-boot) were extremely effective in destroying Allied shipping. In the mid-Atlantic, There was an extensive trade in war supplies and food, which was critical for Britain's survival.
  3. 3. Detail from John Hamilton's painting of a wolf pack attack on merchant vessels.
  4. 4. • The speed and range were severely limited underwater while running on battery power, U- boats were required to spend most of their time surfaced running on diesel engines, diving only when attacked or for rare daytime torpedo strikes. • The most common U-boat attack during the early years of the war was conducted on the surface and at night. • Before the Allied forces developed truly effective antisubmarine warfare (ASW) tactics, this period was referred to by German submariners as "die glückliche Zeit“ (the happy time) .
  5. 5. Sonar anti-submarine aircraft
  6. 6. Is this the end of submarine ?
  7. 7. The Nautilus • "I touch my country's mind, I come to grips - With half her purpose, thinking of these ships...They mark our passage as a race of men. Earth will not see such ships as those again." John Masefield
  8. 8. Operation Sunshine • It did not surface at the Pole, but continued on, and after 96 hours and 1,830 miles / 2945 km submerged under the ice pack, the Nautilus surfaced in the Greenland Sea.
  9. 9. Nuclear submarines • Cylindrical profile of modern nuclear submarines, which are more hydrodynamic underwater, but less stable on the surface; opposite is generally true of U-boats subs • Radar and anti-submarine aircraft, which had proved crucial in defeating submarines during the War, proved ineffective against a vessel able to quickly move out of an area, change depth quickly and stay submerged for very long periods
  10. 10. ballistic missile submarines (SSBN) • Each submarine was armed with up to 16 UGM- 27 Polaris A-3 nuclear missiles
  11. 11. Cuba Crisis
  12. 12. The secret of the nuclear energy
