Both kinds of aircraft, each with its own benefits, if it is your own J-7, it is more flexible to fly, after all, this additional dorsal fin makes its appearance look thicker, which means that the maneuverability is worse, and it is not as flexible as the original aircraft.

According to Qin Feng's feeling of flying the MiG-21MF in Egypt before, it is definitely not as flexible as his own.

However, another benefit is that the aircraft has a fire control radar.

When improving the J-7, the original plan was to put on the fire control radar, but, after repeated consideration, I felt that the technical difficulty was too great, so I gave up, after all, these current projects are constantly repeated, if it is a model with a fire control radar, it will definitely have to be postponed.

You have to hurry, if you postpone, you may not be able to catch up with anything.

However, this MiG-21MF has been improved into a stout big nose, just to install a radar inside, and the PP21-M radar, which is installed in its intake cone, is also an improvement.

Only in this way can it be regarded as making air confrontation possible, why? Because according to the standards of the Eagle Country, whoever locks first wins.

You can't really use missiles with real guns, and you can only win if you shoot them down, right?

With the development of electronic technology in the West, fighter jets have long been fully popularized with radar, starting with the F-4 Phantom, the radar is locked, and missile attack is the main means of air combat.

Although the missile's hit rate is not very high, however, in training, their air combat confrontation subject has developed to prove it with radar locking, and whoever locks on the other side first wins.

In front of the powerful AWG-9 radar of the Tomcat fighter, this small MiG-21 fighter has not yet flown under the noses of others, and I am afraid it has been locked countless times.

After all, the other side can lock on at a distance of 100 kilometers, and this chicken rib radar in front of the nose of the MiG-21 has an interception distance of only 13 kilometers.

What does this mean? For Qin Feng, even if it is visual, he can see the Tomcat fighter thirty kilometers away, and even the most bullish golden helmet in later generations, and the twin-engine fighter can be seen fifty kilometers away.

This radar is not as good as the naked eye, but now it is a piece of evidence, it can tell the other party that I have locked on you and you have lost.

Qin Feng took a deep breath and started the engine behind him, because the fuselage became bulky, so the Soviets also knew that they had to increase the power, and adopted the new P-13-300 turbojet engine of the Tumansky Design Bureau, with an afterburner thrust of 64.72 kN, which was a little larger than the previous model.

This engine, at present, is being surveyed and copied, it is said that many parts are the same, just some compressor parts and other improvements, but surveying and mapping are very difficult, until now, Song Lao's J-7 3, is waiting for this thing.

With the start of the engine, the confrontation was finally about to begin, Qin Feng took a deep breath, in his cockpit, Qin Feng turned his head, and saw the tall Tomcat fighter on the tarmac next to him.

For such a small confrontation, Grumman did not plan to find professional pilots at all, if it was to send the pilots of the famous TOP GUN, it would definitely not be the next situation, and it would be the most stupid to underestimate the opponent. However, Grumman now doesn't think so.

Test pilot Edwards, and his partner Brown, stepped into the cockpit, for them, this confrontation, is simply meaningless, in the morning, they just gave the plane back from the test flight, this confrontation in the afternoon, as the second test flight.

For the two of them, this flight, that is, taking off, turning on the radar, locking on the target, and then returning home, is just as easy.

After Edwards stepped into the cockpit, he also turned his head to look, just opposite Qin Feng's gaze, he gave a thumbs up, and said on the radio: "Tower, please take off first." ”

For Cross, this can be regarded as goodwill, after all, people are here to buy planes, there is no need to be unhappy, Grumman, which survives by selling planes, and they, the test pilots, also rely on the company to provide high salaries.

If their Tomcat fighter takes off first, then as long as Qin Feng takes off, he will always be in the scanning of the Tomcat fighter and can lock it at any time, so what's the point?

Therefore, let Qin Feng take off first, let him prepare first.

Faced with this proposal, Qin Feng did not refuse, he released the brakes, the plane taxied to the runway, and after aiming at the runway, it began to slide.

Since it was just a confrontation, he didn't have any plug-ins, the wings were empty, so that the plane was lighter, and with the blazing flames in the tail, his MiG-21MF glided slowly on the runway.

Qin Feng has not piloted this kind of fighter for once, but every time he flies it, he is abroad, and he is flying someone else's plane, which is really a special treatment.

The take-off of the third-generation aircraft is very fast, even if it is the Mirage 2000, the take-off is very chic, but the take-off of the MiG-21 fighter is like a broken car.

Qin Feng didn't turn on the afterburner, although it was very cool to turn on the afterburner, but this kind of plane didn't have much fuel in the first place, and he didn't have a secondary fuel tank, so he had to save it, relying on two tons of internal oil, if he really turned on the afterburner, it would be gone for a few minutes, and the precious afterburner would be saved for the confrontation.

The plane accelerated slowly, accelerated, and almost reached the end of the runway before leaving the runway, and just one take-off made the experts present very ashamed.

What is Qin Feng doing, does this still need to be tested? Just look at the current take-off, how can this kind of aircraft compete with third-generation aircraft?

Everyone had no confidence, only General Lin on the side said in his mouth: "This kid is still smart." ”

Smart what?

Stingy with fuel, reluctant to drive afterburner, and, after taking off, he did not climb high, just pulled up more than a hundred meters, and it was already leveled, and he left the runway of Grumman's factory at such a height and disappeared from everyone's sight.

If he climbs directly into the air, it is inappropriate, and it is easy to be detected by the other party's radar, however, the opponent's radar has a pulse Doppler function, even if he flies at an ultra-low altitude, he can't hide for long, right?

Of course, Qin Feng knew that what he was hiding was not the radar of the Tomcat fighter at all, he was hiding from the radar used in the factory test flight, and soon, he disappeared on the radar screen of the base, and he had entered the blind spot.
