MILITARY TECHNOLOGY QUIZ – Technology Quiz Questions Part 3

greatest battle implement ever devised”?
A) Garand rifle
B) Bazooka
C) Sherman tank
D) Colt .45 pistol
Answer: Garand rifle
After 17 years of work, John C. Garand came up with a gas-operated weapon
of .30-inch calibre that was 43 inches (109 cm) long yet weighed only 9.5 pounds
(4.3 kg). His rifle was fed from an eight-round clip. Adopted in 1936, the Garand
rifle (also called the M1 rifle) became the first standard-issue autoloading infantry
rifle in the world. U.S. General George S. Patton called the M1 “the greatest battle
implement ever devised.”
20) Who was responsible for some of the earliest, widely influential
development of military rockets?

B) Hermann Oberth
C) William Congreve
D) Robert Hutchings Goddard
Answer: William Congreve
Sir William Congreve, an English artillery officer and inventor born in 1772, made
great advances in black-powder rockets. He gradually improved his rockets’ range
and accuracy, leading many European countries to form rocket corps, usually
attached to artillery units. The Congreve rocket, first used in 1806, were made
obsolete by improved artillery and ordnance.
21) What was the most successful vertical and short take-off and landing, or
V/STOL, jet developed during the 1950s–1970s?
A) Spitfire
B) Mirage
C) Harrier
D) Mosquito
Answer: Harrier
The Harrier, a single-engine, “jump-jet” fighter-bomber, was the most successful
vertical and short take-off and landing, or V/STOL, jet developed during the
1950s–1970s. The Sea Harrier saw combat in the British campaign during the
Falkland Islands War of 1982. A version built for the U.S. Marines was used for
both air defense and support of ground forces.
22) Which ballistic missile, fitted to submarines beginning in 1979, became the
principal sea-based nuclear weapon of the United States?
A) Trident
B) Harpoon
C) Polaris
D) Poseidon
Answer: Trident
Under development from the late 1960s, the Trident missile developed into two
models: the Trident I, or C-4, and the Triden II, or D-5. Beginning in 1979, Trident
I missiles were fitted aboard older U.S. Poseidon-carrying submarines and newer
Ohio-class vessels, which were built with larger missile tubes designed to
accommodate the Trident II in the 1990s. It became the principal sea-based nuclear
weapon of the United States.
23) The launching of which naval vessel started a race to produce turbinepowered “all-big-gun” warships?
A) Dreadnought
B) Bismarck
C) Yamamoto
D) Missouri
Answer: Dreadnought
HMS Dreadnought was a British battleship launched in 1906. Its four propeller
shafts, powered by steam turbines instead of the traditional steam pistons, gave it
an unprecedented top speed of 21 knots. Dreadnought carried a single-calibre main
armament of 10 12-inch guns in five twin turrets. The Dreadnought immediately
made all preceding battleships obsolete, but by World War I it was obsolescent
itself, having been outclassed by faster “superdreadnoughts” carrying bigger guns.
24) Which two aeronautical engineers, serving opposing sides during World
War II, independently invented the jet engine?
A) Frank Whittle and Hans Joachim Pabst von Ohain
B) Aleksandr Yakovlev and Wernher von Braun
C) Leroy Randle Grumman and Ernst Heinrich Heinkel
D) Geoffrey de Havilland and Willy Messerschmitt
Answer: Frank Whittle and Hans Joachim Pabst von Ohain
While still a cadet at the Royal Air Force College, Cranwell, in 1928, Englishman
Frank Whittle advanced the idea of replacing the piston engine and propeller with a
gas turbine, and in the following year he conceived the turbojet, which linked a
compressor, combustion chamber, and turbine in the same duct. Unaware of
Whittle’s work, three German engineers independently arrived at the same
concept: Hans Joachim Pabst von Ohain in 1933; Herbert Wagner, chief structural
engineer for Hugo Junkers, in 1934; and government aerodynamicist Helmut
Schelp in 1937. Whittle had a running bench model by the spring of 1937, but
backing from industrialist Ernst Heinrich Heinkel gave von Ohain the lead. The He
178, the first jet-powered aircraft, flew on August 27, 1939, nearly two years
before its British equivalent, the Gloster E.28/39, on May 15, 1941.
25) What is the oldest still-floating commissioned warship in the world?
A) HMS Victory
B) HMS Warrior
C) USS Missouri
D) USS Constitution
Answer: USS Constitution
One of the first frigates built for the U.S. Navy, the Constitution was launched in
Boston, Massachusetts, on October 21, 1797; it is the world’s oldest commissioned
warship afloat. (The HMS Victory is older [1765] but is preserved in a drydock at
Portsmouth, England.)
26) Which early U.S. and Soviet jet fighters engaged in history’s first largescale jet fighter combat?
A) F-86 Sabres and MiG-15s
B) P-51 Mustangs and MiG-3s
C) F-4 Phantom IIs and MiG-21s
D) F-104 Starfighters and MiG-17s
Answer: F-86 Sabres and MiG-15s
In December 1950, U.S. pilots flying F-86s began history’s first large-scale jet
fighter combat against Soviet-built MiG-15s in Korea. Though inferior to the MiG15 in weight of armament, turn radius, and maximum speed at combat altitude, the
F-86 quickly established supremacy over its Soviet adversary, in part because of its
superior handling characteristics.
27) What did Lieutenant Jan J. Wichers of the Dutch navy invent in 1933
when he advanced the idea of supplying air to submarine diesel engines
through a tube?
A) the supercharger
B) Fuel injection
C) the snorkel
D) the periscope
Answer: the snorkel
A notable German submarine development of World War II was the schnorchel
device (Anglicized by the U.S. Navy to “snorkel”). Its invention is credited to a
Dutch officer, Lieutenant Jan J. Wichers, who in 1933 advanced the idea of a
breathing tube to supply fresh air to a submarine’s diesel engines while it was
running submerged. The Royal Netherlands Navy began using snorkels in 1936,
and some fell into German hands in 1940.
28) Which weapon, commonly employed by urban guerrilla fighters, is known
in Russian as the Ruchnoy Protivotankovy Granatomet?
A) RPG
B) Surface-to-air missile
C) Land mine
D) AK-47
Answer: RPG
Following World War II, the Soviet military perfected the recoil-less launch
mechanism in their Ruchnoy Protivotankovy Granatomet 2 (RPG-2), a “Light
Antitank Grenade Launcher” featuring a reusable launcher that lobbed an 82-mm
shaped-charge warhead more than 150 metres. After 1962, with their RPG-7, they
combined recoil-less launch with a rocket sustainer to deliver a 2.3-kg (5-pound)
warhead to targets beyond 500 metres. The Soviet RPGs became powerful
weapons in the hands of guerrillas and irregular fighters in conflict against more
conventionally armed and heavily armoured forces.
29) What was given the nickname “Stalin Organ”?
A) Katyusha rocket launcher
B) Red Army radio
C) Myasishchev M-4
D) first Soviet hydrogen bomb
Answer: Katyusha rocket launcher
Soviet rocket development during World War II was limited. The Soviets massproduced a 130-mm rocket known as the Katyusha. From 16 to 48 Katyushas were
fired from a boxlike launcher known as the Stalin Organ, mounted on a gun
carriage.
30) What fighter plane of World War II came out of a design for a racing
seaplane?
A) F6F Hellcat
B) SBD Dauntless
C) Spitfire
D) Zero
Answer: Spitfire
In 1925 a revolutionary aircraft design appeared—the S.4 seaplane designed by
R.J. Mitchell of the British Supermarine Company. A wooden monoplane with
unbraced wings, the S.4 set new standards for streamlining. It was the progenitor
of a series of monoplanes that won the coveted Schneider Trophy three times. The
last of these, the S.6B, powered by a liquid-cooled Rolls-Royce racing engine with
in-line cylinders, later raised the world speed record to more than 640 km (400
miles) per hour. The S.6B’s tapered fuselage and broad, thin, elliptical wings were
clearly evident in Mitchell’s later and most famous design, the Spitfire.
31) In 1937 Andrey Nikolayevich Tupolev was arrested by the Soviet secret
police but was allowed to earn his freedom by designing what instruments of
war?
A) Bombers
B) Tanks
C) Fighters
D) Machine guns
Answer: Bombers
In 1937 Andrey Nikolayevich Tupolev, one of the Soviet Union’s foremost aircraft
designers, was arrested on charges of activities against the state. Following his
imprisonment, he was placed in charge of a team that was to design military
aircraft. From this came the Tu-2, a twin-engine bomber that saw wide use in
World War II and earned Tupolev his freedom and a Stalin Prize.
