Chapter 521 Air Defense Operations
The anti-aircraft gunners on Cleveland maintained the highest alert. As soon as the enemy plane appeared in the field of vision, the anti-aircraft weapons on the ship began to work.

The first thing to fire was the 127mm twin-mounted MK12 naval gun on the ship. This kind of naval gun is equipped on many American ships, ranging from small Atlanta-class light cruisers to large ones such as Iowa and Essex. .

The anti-air efficiency of this large-caliber anti-aircraft gun was originally very low, but it changed after the appearance of VT bombs.

The previous large-caliber anti-aircraft guns were both contact fuzes and timed fuzes. The former could cause damage only when it touched the target, while the latter could easily be detonated too far ahead or too far behind, and the efficiency was very low.

But the VT (Variable Time) fuze, that is, the proximity fuze is different. When it flies near the target, it will automatically detonate the shell, and then use fragments to kill the enemy aircraft. The hit rate has an epic buff.

The 5-inch shell's first-generation VT proximity fuze was about the size of a beer mug and had five tubular radio transceivers on its head that were constantly transmitting and receiving radio signals.When it flew about 5 meters away from the target, the electric detonator detonated the main detonator, and the shell exploded.

The debris covers an area of ​​278.7 square meters, and shells that do not fly into the target area will automatically detonate after a certain period of time.

The specific working principle of this kind of proximity fuze is as follows: the impact force of the shell when it is launched breaks a small glass bottle containing the electrolyte, the rifling of the barrel makes the shell start to rotate, and the electrolyte is thrown to the surrounding insulated electrode plates by centrifugal force On the ground, a current is generated immediately, and the current immediately charges a capacitor. At the same time, the current starts a radio vacuum tube, and the vacuum tube emits a radio wave. The radio wave reflected by any object will be received by an oscillator. A "ripple" electrical pulse.

This pulse is amplified by a radio vacuum tube, and when the shell flies within 21 meters of the target, the pulse is large enough to activate an electronic thyratron, the current stored in that capacitor is instantly released, an electronic detonator is detonated, and it Detonate the main detonator.

One after another, the 5-inch shells were fired by the MK12 naval gun on the side of the USS Cleveland, and flew head-on towards the enemy planes that rushed over.

As for Otowa... she is flying at a very low altitude now, and the buoys are almost being hit by the waves, so there is no need to worry about being shot down by friendly artillery fire.

The USS Cleveland is equipped with a total of 6 MK12 dual-mounted naval guns, one in the front, one in the back, one on the left, two on the right, and a maximum of four turrets can attack together on one side.

These 127mm twin guns had an extremely fast rate of fire, capable of firing 15-22 rounds per minute.When the artillery in the four turrets fired together, the distant sky was instantly covered by countless shells.

boom boom-

The black mist produced by the shell explosion covered the airspace where several enemy planes were located, and countless fragments rushed towards these enemy planes in an instant.

If it is an excellent American bomber with rough skin and thick flesh, it may be able to resist some fragments, but it is a pity that the first few planes are unprotected, and the pilots do not even have bulletproof seats and glass for zero combat.

Soon, the first Zero War came down from the sky and had a close contact with the icy sea water.

"NICE, well played!"

Seeing that the enemy plane that was chasing him just now was shot down, Otowa couldn't help cheering.

There is reincarnation in the way of heaven, good and evil will eventually be rewarded!

With the first victim, the second soon appeared.A Zero Fighter seemed to have been hit by a fuel tank, and it turned into a turkey in an instant.

The anti-aircraft gunners Arisa recruited were all carefully selected, and all of them were elites from the navigation department of their school, and they were all accurate when flying planes.

After paying the price of several planes, the remaining enemy planes finally approached the USS Cleveland.

Several of the Type [-] attack ships began to lower their heights, as if they wanted to use torpedoes to deal a fatal blow to Otowa and the others' warships.

The small-caliber anti-aircraft guns on the USS Cleveland started to work one after another. The densely packed anti-aircraft guns on the bridge deck of the ship are not for decoration.

Although the 40mm Bofors cannon and the 20mm Oerlikon cannon are not equipped with VT bombs, they are strong in large numbers and high firepower density, and the barrage they pull out is quite terrifying.

Teresa firmly placed the enemy plane in the center of the sight by operating the joystick, and then stepped on the pedal without hesitation.

bang bang bang bang-

The two 40mm Bofors cannons in front of her fired in turn, firing 40mm shells at the enemy plane in the distance.

While she was shooting, the mechanical arm on the side was also continuously filling the shells into the cannon from above.

Unlike the 25mm machine gun that uses magazines, the Bofors can be loaded directly. The loader only needs to throw a group of four shells in from above, so there is no such a long vacuum period as the 25mm machine gun. .

The lethality of the 40mm shell is extremely strong, and the charge is almost double that of the 28mm shell.The Zero Zhan hit by Teresa broke its wings on the spot, and then fell to the sea.

AI is better than humans in some aspects, at least they will not panic when being attacked by barrage, and they can still drop bombs in an orderly manner.

A Type 20 naval attack dropped the torpedo under the fuselage, and when the AI ​​on it was about to pull the fighter up, a [-]mm armor-piercing incendiary bomb suddenly appeared and exploded its fuel tank.

After the torpedo fell into the water, the propeller at the tail spun rapidly, pushing the projectile towards the USS Cleveland not far away.

Although the power of aviation torpedoes is not as good as that of shipborne counterparts, it still hurts to get hit.

"Port side, the torpedo is approaching!" The observer shouted from the bridge.

"Right full rudder!"

Even under such circumstances, Shizuku still looked very calm.

The helmsman quickly steered the rudder and forcibly changed the direction of the ship.

Fortunately, they discovered it early. With the strong rudder effect of the Cleveland, they managed to complete a 90° turn before the torpedo touched, avoiding the white line on the sea by a slight margin.

"Fortunately it's not a magnetic torpedo."

Looking at the torpedo that lost its target on the sea, Arisa couldn't help but breathe a sigh of relief.

Magnetic torpedoes and VT bombs have the same purpose, and there may be some differences in principle, but they both actively detonate when they are close to the target, and it is not easy to avoid them.

Under the fierce anti-aircraft fire of the USS Cleveland, the remaining Zero Battles were quickly shot down.

There were a total of eight enemy planes that attacked them just now, and only one Type [-] bomber dropped the bomb, and none of them could fly back alive in the end.

Your father is still your father, the anti-aircraft firepower is not a joke, so few planes dare to come... Isn't it courting death?
