During WWII, the Allies mounted the High Velocity Aircraft Rocket (HVAR), an unguided rocket, to many of its planes. It was nicknamed the Holy Moses, ostensibly for the reaction uttered by bystanders who witnessed its effects.

2. both

The Axis loved the Bordkanone 5 (BK 5) cannon, a 50 mm gun that was meant to shoot down the Allies' heavy bombers. With their high velocity, fighter pilots could unleash a torrent of rounds outside the range of a bomber's defensive machine guns.

1. heat-seeking rockets
   a cloaking system
2. computer-controlled machine guns

The B-29 was fantastically advanced for the era. It featured remote-control machine guns, with a computer-aided targeting system. It made the bomber fearsome to enemy fighter pilots.

There were 13 M2 machine guns aboard the B-17. Those guns spewed enough lead to take down an entire squadron of enemy fighters.

1. an atomic bomb
   a nuclear missile
2. a rocket launcher

The Werfer-Granate 21 was a rocket launcher with air-to-air capabilities. German fighter pilots could loose them from nearly a mile away, keeping them safer from Allied bomber machine guns.

2. Japan

Japan deployed the Type 97 aircraft machine gun on thousands of its warplanes. It was not the same equipment as the similarly named Type 97 machine gun used by infantry.

1. using their teeth
   by hand
2. with remote control

Early in the war, many German fighter were armed with the MG 15, a 7.92 mm machine gun. It was a hand-operated weapon, meaning the pilots had to do some multitasking during dogfights.

The first variants of the Spitfire were equipped with eight .303in Browning machine guns. Each of the guns maxed out at 300 rounds.

1. very effective
   not effective
2. almost harmless

In the early stages of the war, the .303in machine guns were very good at bringing down German planes. But once Axis engineers began adding more armor to their planes, the Spitfire's guns weren't quite as deadly.

1. a SAM
   a cannon
2. a flare launcher

Germany loaded its MK 108 -- a 30mm caliber autocannon -- on many of its warplanes. Fighters could blast away at Allied bombers at a rate of more than 600 rounds per minute.

1. air-to-air rockets

2. cat lasers

As bomber crews got better at defending their planes, fighters tried to stay out of range of their machine guns. To so so, the fighters launched air-to-air missiles in hopes of downing bombers.

   Army/Navy
2. Anti-Nazi

The .50 Browning AN/M2 was the Army/Navy version of the famed "Ma Deuce." It could be installed as a fixed gun on aircraft (or ships) and wired to a remote trigger.

1. other planes
   ground targets
2. aircraft carriers

The Vickers S 40 mm gun was a powerful addition to some Allied planes, like the Hurricane. The huge rounds were great for destroying ground targets.

1. They were for training purposes.
   They were used to attack submarines.
2. They were child's toys.

The first variations of the 5-Inch Forward Firing Aircraft Rocket (or FFAR) were meant to destroy submarines. They didn't need explosives -- instead, they simply made holes in the subs to sink them.

1. America
   Japan
2. USSR

The ShVAK cannon was a 20 mm cannon made by the USSR for many of its planes and even some light tanks. It weighed just 90 pounds but could fill the skies with 800 rounds per minute.

1. 2,000
   10,000
2. 90,000

The B-17s alone dropped about 640,000 pounds of bombs on Germany in WWII. Advanced variants of the B-17 could carry as much as 10,000 pounds of bombs.

1. They weren't guided.

2. GPS

The RS-82 was a family of unguided missiles used by Soviet aircraft in WWII. The lack of guidance didn't stop pilots from downing plenty of enemy fighters and bombers.

1. It incorporated a flamethrower.
   It had two guns instead of one.
2. The Z was meaningless.

The MG 81 was a belt-fed 7.92 mm machine gun. It was doubly dangerous in its Z incarnation -- it had two guns built into one, maxing out at around 1,600 rounds per minute.

1. 45 rounds per minute
   400 rounds per minute
2. 850 rounds per minute

Compared to a machine gun, the BK 5 cannon was slow -- 45 rounds per minute. But what it lacked it speed, it more than made up for in punch.

1. to give the bullets a boost in velocity
   so fighters could attack bombers from below
2. to prevent fighters from actually hurting anyone

German engineers realized that Allied bombers had a blind spot below their planes' bellies. German fighters mounted the MK 108 cannon at a bit of an upward angle and attacked from below with little risk to their own aircraft.

1. large hoppers
   children with fast hands
2. belt-feed mechanism

The Type 99 Mark 1 Model 4 used a belt-feed system to increase the number of rounds each plane could carry. It fired 20×101RB cartridges.

1. It had no moving parts.
   It used a matchlock firing system.
2. It was lightweight.

Germany's MG FF cannon was a lightweight 20 mm autocannon used for both offensive and defensive purposes. It weighed just 60 pounds, making it perfect for many Luftwaffe aircraft.

1. the GPS unit
   the suicide pilot
2. the laser guidance system

The Yokosuka MXY-7 Ohka was basically a bomb-laced plane meant to be steered into a target by a kamikaze pilot. The concept alone was enough to terrify American sailors in the Pacific War.

1. It was very heavy.
   It never worked.
2. It shot confetti instead of bullets.

The MK 101 cannon was a 30 mm monster. In some variants it weighs more than 300 pounds, a fact that made it unwieldly for many aircraft.

1. bombers
   fighters
2. dive bombers

The Hispano-Suiza HS.404 was an autocannon that found its way to the wings of many Allied fighters in WWII. But its drum magazines only held 60 rounds, meaning pilots quickly depleted their ammo during heavy fighting.

1. Browning M2
   Thompson submachine gun
2. M1 Garand

With its high-speed .50-caliber death blasts, the Browning M2 is one of the world's legendary machine guns. It's no wonder that Japan wanted their own version, the Ho-103 machine gun.

1. Tiny Tim
   Mighty Mouse
2. Angry Toddler

It was a 2.75-inch unguided missile that American planes often used as a ground-attack weapon. The Folding-Fin Aerial Rocket was also called Mighty Mouse, and it was nearly worthless as an air-to-air weapon.

1. The guns lacked power.
   The cannons were defective.
2. The cannon made the plane hard to fly.

German engineers kept adding bigger and bigger guns to the Henschel Hs 129, including a 75 mm monster. But the gun was so heavy that pilots could hardly fly their planes.

1. They added explosive rounds.
   They included a powerful laser.
2. They used computer-aided targeting.

The Ho-103 machine gun used 12.7x81mmSR rounds, which were plenty dangerous to enemy aircraft. To make them even deadlier, the guns were often loaded with explosive rounds that did more damage to targets.

   tanks
2. P-47s

As the USSR deployed thousands and thousands of tanks, the German Lufwaffe needed a way to blast through so much armor. The BK 3,7 was mounted to numerous fighters and ground attack planes in hopes of stemming the tide of Red Army armor.
