    True
17. ASDIC, an early form of sonar, helped warships detect submerged submarines by using sound waves.

    Destroyer
19. A sailing fleet wants to break a well-drilled enemy line and turn it into a close-range brawl where training and initiative matter more than perfect formation. Which tactic best fits that goal?
    Attack in columns to cut through the enemy line and force close-range chaos
20. In World War I, submarines were generally more effective at sinking major warships than at attacking merchant shipping.
    False

    True
28. A privateer was legally authorized by a government to capture enemy merchant ships.

    Dardanelles
30. A navy is converting from coal to oil fuel and expects faster turnaround between operations. What advantage best explains why oil became so attractive?
    Oil had higher energy density and could be pumped quickly, boosting range and readiness
31. A “distant blockade” relies on controlling exits and approaches rather than sitting directly off an enemy’s harbors.
    True
32. Which battle is best known for Japan’s decisive defeat of Russia and for showcasing modern gunnery, signaling, and fleet maneuver?
    Tsushima
33. In the Battle of the Atlantic, escort carriers were most valuable because they could do what?
    Provide air cover and anti-submarine patrols for convoys
34. Which doctrine argued that a weaker navy could threaten great powers by emphasizing commerce raiding, cruisers, and torpedo craft rather than building a battle fleet?

    A long, exhausting voyage that strained crews and machinery and made coaling a constant crisis

    Preventing the enemy from using an area, even if you cannot use it yourself
40. In Age of Sail tactics, why was having the “weather gauge” so valuable?
    Upwind position gives choice of engagement and can deny the enemy wind
