5. Technology of World War One In no other war has technology played such a critical role in impacting how the war would be fought. The First World War began as a clash of 20th century technology and 19th century tactics, with inevitably large casualties. Think of these weapons/technologies as solutions to problems

6. Technology of World War One Machine Guns Artillery Grenades Communications Transportation Tanks & Armor Aircraft Chemical Warfare U-Boats Convoy system Barbed Wire All of these technologies had an impact on the strategy and tactics of the war. Some were used in a new way, others were used in response to other technologies or new tactics and strategies.

7. 1. TRENCH WARFARE Description: Series of progressively more improved trenches with interconnecting trenches Use: Trenches, often reinforced with wood, with larger underground bunkers dug in side for more protection –Strategy employed because of stalemate, machine guns & artillery Impact: Many weapons and tactics were created to overcome the defensive nature of trenches

10. MACHINE GUN

11. 2. MACHINE GUN Description: Rapid fire weapon (400-800 rounds/minute) typically crewed by several men Belt-fed,.30 cal (typical) Use: Anti-personnel, used against massed infantry Impact: –Possibly the most influential weapon of the war –Contributed to stalemate and affected tactics –No longer would massed infantry be the most effective Evolution: –Would be mounted on airplanes and armored vehicle –Became smaller, less crew (squad-level weapon) –Submachine guns at end of war

12. ARTILLERY

13. 3. ARTILLERY Description: Large caliber weapon capable of direct or indirect fire Use: artillery barrage to soften up targets Impact: Huge guns to destroy fortresses, extreme long range attacks Evolution: improved accuracy, range, –better shells and fuses, improved explosives –Faster reload, more portable –Self-propelled artillery

14. Artillery Paris Gun Typical German Artillery piece

15. 4. GRENADES Description: Small, explosive device Use: Thrown or projected to cause burst and shrapnel damage to enemy –Percussion (contact) or timed fuse –Old weapon found new use in trench warfare – often referred to as “bombs” Impact: well-suited for trench warfare (indirect throw) –Becomes core of new trench assault strategy –sturmtruppen – trench raiders - bombers

16. Grenades

17. 5. AIRCRAFT Description: Constructed of canvas stretched over a wooden frame. Use: Initially used for observation, later for actual combat ** –Single pilot fighter to several men in a bomber –Typically armed with machine guns Impact: –Anti-Aircraft and aerial pursuit, surveillance –Bombings eventually via plane –Most aerial combat techniques used today are derived from WW1 dog fighting. –Fixed wing aircraft most influential, though observation balloons and zeppelins played a role as well Evolution: –Unarmed observation craft, Then purpose-built fighters, followed later by bombers - U.S. would pioneer large-scale bombing missions late in war –Fighter Aces – five kills

18. Sopwith Camel

19. Red Baron’s Plane

20. Bombers and Zeppelins

23. SUBMARINES

24. 6. SUBMARINES Description: Naval structure designed to sail below sea level; originally used by the Germans Use: attack Allied shipping, primarily through use of deck guns and torpedoes Impact: –Very effective against shipping, but sinking of ocean liners was negative public opinion –Use of convoy system, depth charges and hydrophones were a response Evolution: Submarines would get larger and faster with expanded undersea capability Improved torpedoes

25. TANKS & ARMOR

26. 6. TANKS & ARMOR Description: Tracked, armored vehicle armed with machine guns and/or cannons. Use: Used to assault trenches, destroy barbed wire obstacles, machine gun nests –2 (6.5t) crew to 16 (32t) crews; 3-8 mph Impact: somewhat effective depending on use; infantry support, combined arms –Debate about use breakthrough vs. support –Mechanical breakdowns, lack of speed

27. German Tank

28. Armored Car

29. BARBED WIRE

30. 7. Barbed Wire Description: Sharp twisted strands of wire Use:– not designed to kill but instead maim (hurt), create barriers –Often used in conjunction with machine guns and trenches –Create barriers while preserving field of fire –Control avenues of approach Impact: critical to trench defense

31. COMMUNICATIONS

32. 8. Communications Description: New methods include telephones and wireless (radio) Use: Devices designed to improve communication between front lines-troops, etc. Impact: Would allow for swift communications for better control by command elements –Key for Command and Control –Used for Artillery Spotting –Need for codes and ciphers (Russians sent radio signals “in the clear” – allowed for Germans to know their plans –Runners, carrier pigeons still used throughout war

33. CHEMICAL WARFARE

34. 9. Chemical Warfare Description: Chemical, gas-based warfare designed to end the stalemate of trench warfare Use: Chemical gas used to incapacitate or kill enemy –Mustard, chlorine, and “tear gas” –Horrible wounds and death –Initially just “sprayed” –Hard to control Impact: Troops had to wear masks making fighting difficult –Masks often ineffective Evolution: Better means of dispersal –artillery shells and bombs –Although outlawed, chemical weapons still made throughout cold war

35. Casualties of Modern Weaponry Tactics of sending masses of men toward enemy didn’t work against modern weapons British suffered 57,470 casualties on the first day of the Battle of Somme Total losses for World War I exceeded 10 million

36. Project: WWI Tech. Brochure WWI is considered the first modern, technological war. You will make brochure advertising the merits of the weapons used in WWI. You will need to choose FIVE (5) of the types of weapons from your notes to feature in the brochure. For each weapon’s section in the brochure, you need to include the following: *30 POINTS TOTAL* –The weapon’s name (1 point) –At least 5 facts about that weapon (should include some evidence of extra research using your phone, the computers, etc.) and how it impacted WWI (15 points) –A relatively detailed drawing of that weapon (5 points) –Also impacting your grade will be: use of color, neatness, grammar/spelling (3 points each – 9 points total)
