"Tom Tom Tom!" The 20mm M61 Vulcan machine gun, at the lower left side of the nose, fired violently. The revolving machine gun gave out waves of flames, accompanied by heavy smoke, and the shells flew out. .
This is an American general-purpose cannon. It is a Gatling cannon that uses external force to drive six barrels, air-cooled, and electronically fired.
As long as you know the principle of Gatling, you know the terrible rate of fire of this gun. With the rotation of the barrel, 20 mm shells fly out. In the limit, its rate of fire is as high as 7200 per minute. However, in actual operation, you can choose between 4000 rounds per minute and 6000 rounds per minute.
Normally, the average pilot will choose a rate of fire of 4000 rounds, the reason is quite simple, because there are not many shells!
For fighters of this era, the cannon is actually a supplement. Few fighters can exchange fire to the point of using cannons. When the missile victory was over a decade ago, the cannons were even cancelled.
Cannonballs have weight. The more ammunition prepared, the heavier the weight is, which is not conducive to the maneuverability of the fighter. Therefore, even the heavy Tomcat fighters only have 676 rounds of ammunition, one shot less than one shot.
Cannonballs need to be used less, so a lower rate of fire is beneficial. At the same time, because the rate of fire is high, the bullet chain is pulled at this high speed, and the joints are easily deformed, bent or even broken, causing the cannon to jam, so generally Both use the lowest rate of fire of 4000 rounds.
Even so, Nathan only dared to gently place his finger on the red shooting button, and then the vibration of the fuselage began. Even in just a few seconds, hundreds of shells had flown out.
These flying artillery shells just right hit the other side's abdomen, and countless 20mm artillery shells entered it, "Boom!" There was a loud noise in the sky.
Early fighters used machine guns as weapons, but the power of the machine guns was too small. It often happened that they were punched with hundreds of bullet holes and returned safely. In order to increase the lethality, later fighters began to use machine guns. Up.
A 20mm cannon can tear a hole with just one shell, and a large number of 20mm shells rushed in, instantly blasting this fighter into the air!
After Nathan finished shooting, he immediately pulled the joystick and kicked the rudder to avoid the debris. This was a very dangerous distance.
After all, when the fighters started to fight the cannons, they were almost fighting with bayonets in the air. The tail biting attack was dangerous, not to mention that it was a head-on attack. A second later, the Tomcat fighters would explode. After leaving, his engine will also suck in countless fragments, and then it will start to catch fire.
Nathan avoided perfectly.
The opponent was shot down during the climb, and Nathan turned sideways and dived, and just like that, he left the airspace almost on the edge of the flying debris.
Keep going!
Gus in the back seat is extremely excited at this time, Major Nathan, awesome!
During the Second World War, there will be a trump card that shoots down hundreds of planes. This is rare. However, a few dozen or a dozen planes will be shot down. According to the rules, as long as you shoot down five, you can become a trump card.
That was the era of propeller planes. A fighter jet was almost as expensive as a tank. Now, as we enter the jet era, fighter planes have become quite expensive, and the number of fighter planes has begun to decrease. We want to have more shots down. ,That is impossible.
What about Major Nathan
Not on the battlefield in Vietnam, just now, in a reconnaissance flight, Nathan has already shot down two fighters, which is half the trump card!
And they want to return to the voyage, it is destined to not be smooth sailing.
For the second Su-15, the pilot did not have a chance to parachute. At this time, Nathan was like Guan Gong riding a thousand miles alone, passing five levels, and beating six generals. He wants to return to his side, the voyage is still far away!
At this time, Nathan had flown over Obrevistoye, in the southeast of Sakhalin Island, had left the land below, and reached the sea.
"PS mode." Nathan shouted: "Pay attention to searching for the target in front of us."
Hearing this, Gus in the rear cabin was taken aback. Out of absolute trust in Nathan, he immediately turned the operating knob of the radar and adjusted it from PDS mode to PS mode.
PDS mode is pulse Doppler search, which is a state of working in pulse mode while using the Doppler effect. It is mainly used for road lighting and is the most common mode during battle cruises. At the same time, the distance is also very far, the farthest is more than 300 kilometers, which is in this mode.
In contrast, the PS mode is pulse search, (not p photo.)
This mode has no Doppler effect and only works in a state of pulse mode.
It can be said that this is a mode that has been used as soon as the radar appeared. Almost all airborne radars have it. It has no special features. It is basically equivalent to buying a battery for a remote control or a set for sex toys.
In the PS mode, it is still "search", but the detection range is greatly reduced, which is about a half discount compared to PDS. It is only half of the discovery range. It used to be over 300 kilometers, but now it is 150 kilometers.
In this case, it seems to be a tasteless existence, it is useless, but in fact, it is necessary, because the pulse Doppler mode will use the Doppler effect to filter out some things, and this PS mode is just right. Avoid some blind spots in PDS mode, such as targets in the same direction and speed, targets across tracks, etc.
With the adjustment to the PS mode, in an instant, four more bright spots appeared on the screen, and the distance was only 60 kilometers!
These damn cunning Soviets!
When the reconnaissance plane went to the strategic missile launch base again, it definitely stabbed the hornet's nest. At the same time as the two Su-15s intercepted, the four MiG-23s also took off in formation. After receiving the news that the target had begun to return to the southeast, he flew straight to the east, intending to intercept it.
The guides on the ground are also very smart. The route they fly is perpendicular to the returning Tomcat fighter. This is just filtered by the processing system of the pulse Doppler radar. When they fly directly in front of the target, they suddenly turn around. , Directly within the range of the R-23 missile carried by the MiG-23.
Four MiG-23s are enough to form an interception line and shoot eight R-23 missiles. I don't believe that this Tomcat fighter can't be killed!
Unfortunately, as the Tomcat fighters adjusted their radar mode, they appeared on the radar screen again!
"Four goals, sixty kilometers away." Gus shouted.
Four goals came? Nathan gritted his teeth: "TWS mode, lock them all!" (End of this chapter)
