The anti-aircraft gunners on Cleveland were on the highest alert, and as soon as the enemy aircraft appeared in view, the ship's anti-aircraft weapons were at work.

The first to fire was the ship's 127mm twin MK12 naval gun, which was equipped on many U.S. imperialist ships, from the Atlanta-class light cruiser to Iowa and Essex.

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

In the past, large-caliber anti-aircraft guns were all contact fuses and timing fuzes, the former can only cause damage when it touches the target, while the latter is easy to detonate too far or too late, and the efficiency is very low.

However, the VT (Variable Time) fuse, that is, the proximity fuse, is different, it will automatically detonate the shell when it flies near the target, and then kill the enemy aircraft with fragments, and the hit rate has an epic buff.

The 5-inch shell was the size of a draught beer cup with a first-generation VT proximity fuse mounted on its head with five tubular radio transceivers that constantly transmit and receive radio signals. When it flew about 21 meters from the target, the electric detonator detonated the main detonator and the shell exploded.

The fragments cover an area of 278.7 square meters, and shells that do not fly into the target area will automatically detonate after a certain amount of time.

The specific working principle of this proximity fuze is as follows: the impact force of the shell when it is fired makes a small glass bottle containing electrolyte break, the rifling of the barrel makes the shell start to rotate, and the electrolyte is thrown to the surrounding insulated electrode plate by centrifugal force, and the current is immediately generated, and the current immediately charges a capacitor, and at the same time the current starts a radio vacuum tube, and the vacuum tube emits a radio wave, and the reflected radio wave of any object will be received by an oscillator, and the received radio wave and the transmitted radio wave will produce a "ripple" Electrical impulses.

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 thyristor, and the current stored in that capacitor is instantly released, and an electronic detonator is detonated, which in turn detonates the main detonator.

One by one, the 5-inch shells were fired out by the MK12 naval guns on the side of the Cleveland, and flew head-on towards the enemy planes that pounced on them.

As for the sound feat...... She was flying at a very low altitude now, and the pontoons were almost hit by the waves, so she didn't have to worry about being knocked down by friendly fire.

The Cleveland is equipped with a total of 6 MK12 twin naval guns, one in the front and one in the back, one on the left and two on the right, and a maximum of 4 turrets on one side can attack together.

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

Boom Boom Boom –

The black fog from the explosion of the shells covered the airspace where several enemy planes were located, and countless fragments instantly rushed towards these enemy planes.

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 are unprotected, and the pilot does not even have bulletproof seats and glass zero combat.

Soon, the first Zeros descended from the sky and came into close contact with the icy waters.

"NICE, GOOD FIGHT!"

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

There is reincarnation in heaven, and good and evil will be rewarded in the end!

With the first victim, the second victim also appeared quickly. A Zero seems to have been hit with a fuel tank and turned into a turkey in an instant.

The anti-aircraft gunners that Arisa found were all carefully selected, all of them were the elite of the navigation department of their school, and they were accurate when they started the plane.

After paying the price of a few aircraft, the remaining enemy aircraft finally approached the Cleveland.

Several of the Type 97 ships began to lose altitude, as if intending to inflict a fatal blow on Otowa and their ships with torpedoes.

The small-caliber anti-aircraft guns on the Cleveland are working, and the dense anti-aircraft guns on the bridge deck of the ship are not decorations.

Although the 40mm Bofors cannon and the 20mm Erlikong cannon are not equipped with VT shells, they are strong in number and high fire density, and the barrage pulled out is quite terrifying.

Theresa manipulated the joystick, stiffly put the enemy plane in the center of the sight, and then stepped on the pedal without hesitation.

Bang bang –

The two 40mm Bofors guns in front of her took turns firing, shooting 40mm shells at enemy planes in the distance.

As she fired, the robotic arm on the side was constantly filling the cannon with shells from above.

Unlike the 25mm cannon, which uses a magazine, the Bofors can be reloaded directly, and the loader only needs to drop the shells in groups of four from above, so there is no vacuum period for the 25mm cannon.

The lethality of the 40mm shell was extremely high, and the charge was almost twice as much as that of the 28mm shell. The Zero that was hit by Theresa broke its wings on the spot and crashed into the sea.

AI is stronger than humans in some ways, at least they don't panic when they are attacked by bullet hell, and they can still deliver bombs in an orderly manner.

A Type 97 ship's attack dropped the torpedo under the fuselage, and just as the AI on board was about to pull the fighter up, a sudden 20mm armor-piercing incendiary bomb burst its fuel tank.

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

Although the power of aviation torpedoes is not as good as that of their carrier-based counterparts, it still hurts to take a shot.

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

"Right full rudder!"

Even in this situation, Shizuku still looks very calm.

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

Fortunately, they discovered it early, and with the Cleveland's not weak rudder, they succeeded in completing a 90° turn before the torpedo made contact, avoiding the white line on the surface of the sea by a fraction of a second.

"Luckily, it's not a magnetic torpedo. ”

Looking at the missing torpedo on the sea, Arisa couldn't help but breathe a sigh of relief.

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

Under the heavy anti-aircraft fire of the Cleveland, the remaining few Zeros were quickly taken down.

There were a total of eight enemy planes that attacked them just now, and only one Type 97 ship attacked and dropped bombs, and none of them could fly back alive.

Your father is still your father, anti-aircraft fire is not a joke, so many planes dare to break in...... Aren't you looking for death?
