Chapter 106: Powerful AWG-9
In this kind of sea condition, the flight quality of the AWACS aircraft with a large plate is even more unacceptable, especially the danger of landing is very great, and the Tomcat fighter's own radar is also quite powerful, so the wing commander Colonel Ted only catapulted two Tomcat fighters. Pen | fun | pavilion www. biquge。 info
It couldn't be easier to spy on a slow-moving Tu-95 reconnaissance plane of the Soviets with two powerful Tomcat fighters, and, if the lads in the Navy had a little other little action, it was also within the acceptable range of Ted and others.
The most powerful force of the aircraft carrier formation is the carrier-based aircraft! The two flying Tomcat fighters are both airborne mounts.
The Tomcat fighter's signature weapon is the Immortal Bird missile! This large missile, which is 3.96 meters long and 380 mm in diameter, weighs half a ton! Conventional aerodynamic layout, near the center and rear of the missile body, there are four fixed ****** surfaces extending to the tail of the missile, and behind these four wing surfaces are four rectangular control surfaces, with a range of more than 100 kilometers!
However, because this kind of missile is too bulky, if it is mounted according to the long-range interception, each fighter is equipped with six Immortal Bird missiles, it will seriously reduce the maneuverability of the Tomcat fighter, and if the missile is not launched during the mission, when returning to the aircraft carrier, two expensive Immortal Bird missiles must be thrown away, because the Tomcat fighter can only carry up to four Immortal Bird missiles to land on the aircraft carrier.
Therefore, in normal times, Tomcat fighters will not be majestically hung with immortal birds, and the current two Tomcat fighters are only equipped with two immortal bird missiles, plus two Sparrow missiles and two Sidewinder missiles.
At this time, the two fighters catapulted and took off from the aircraft carrier, the engine afterburner in the tail was turned on, the wings swept back, and began to sprint quickly, long-range interception mission!
At this time, at an altitude of several hundred kilometers away, a bright spot was still displayed on the radar, and this bright spot was constantly heading towards the exercise area of the US aircraft carrier.
In the Cold War, this kind of confrontation was all too common, and the two countries often came to harass each other during exercises, such as when the Soviet Navy exercised in the Baltic Sea, and even the frigates of the Soviet Navy had to use hull squeezing to prevent American warships from getting too close.
At this time, on the two Tomcat fighters, the pilots flew in accordance with the target indication direction from the ground radar station, and in the rear cockpit of the Tomcat fighters, the weapon operator was operating in an orderly manner.
Because the launch of the Immortal Bird missile is too cumbersome, in order to allow the pilot to focus on air combat, the Tomcat fighter is a two-seat system, with a weapon operation officer in the rear cabin, which is specially used to control the powerful AWG-9 radar and the Immortal Bird missile system.
Turn on the radar, PDS mode scans the airspace in front, and at the same time, pre-power the Immortal Bird missile and prepare for launch, so that if you really need to launch, you won't be in a hurry.
On the radar screen, bright spots soon appeared.
Like the Tornado-A radar, the AWG-9 radar also weighs half a ton, however, this half-ton weight is the full weight of the entire radar system, while radars like the Tornado-A are net weight, excluding the weight of the cooling system, etc. Moreover, weight is not directly proportional to performance, the AWG-9 radar's flat slot antenna allows the radar beam to radiate better, reduce side lobes, increase the scanning frequency, and improve efficiency, while the receiver uses a large number of solid components, including crystal filters and low-noise parametric amplifiers, and a flexible, high-capacity computer.
AWG-9 is a completely digital computer, this kind of computer is known to many computer fans, it is the 8-bit digital processor of Intel8080! It may sound backward now, but at the time, the processor was simply invincible. The radar processing system written in assembly language allows the radar to process signals in a variety of ways, so that the AWG-9 has seven modes!
Compared with the most critical parameters, the maximum power of this radar is only 8 kilowatts, which can achieve such a strong performance, and the peak power of the Whirlwind-A radar is 600 kilowatts! The power is large, but it is dissipated in the form of heat, and the effective energy used on the radar beam is not much.
At this time, with the full power of the radar, in the PDS mode, the AWG-9 radar for a large target such as a strategic bomber has a maximum detection distance of 300 kilometers.
"Target found, twelve o'clock, about three hundred kilometers away." Said the weapons operations officer in the aft compartment.
PDS mode is pulsed Doppler search, that is, it is a search state that works in pulse mode and uses the Doppler effect at the same time. At this time, it is like a big flashlight, used to see if there is a target in the airspace 65 degrees ahead, that's all, in addition to obtaining the target azimuth information, there are no altitude, speed, and all kinds of other parameters, and it is impossible to guide the missile to attack.
However, this mode has the farthest detection range, and can be found at a distance of 300 kilometers against a target as large as a strategic bomber such as a Tu-95 or B-52. Therefore, the PDS mode is mainly used to illuminate the road, which is a mode often used by Tomcat fighters during combat cruises.
Continuing to track steadily for a few seconds, the weapon operations officer in the aft compartment continued to report: "Ready to switch to PDSTT mode." ”
PDSTT, wearing a sleeve on PDS, this sleeve is the meaning of continuous tracking. The radar still operates in pulse-Doppler mode, but the scanning mode is changed, and one of the intercepted targets is selected for continuous tracking according to the operator's instructions.
At this time, the radar antenna is in a fixed state, and all the radar beams are radiating towards distant targets, and the beams are no longer wasted in other airspace, as if the flashlight has added a focused lens to make the flashlight become a laser.
Keep your eyes on the target and get ready to fire!
As the radar beam continues to radiate and return at the same time, the parameter information of the target, solved by the fire control system, is completely presented on the radar screen.
"The distance is two hundred, the height is sixteen, and the speed is eight hundred." The weapons operations officer in the aft compartment continued to report
Due to the complete interception of target information at this time, it can fully support the fire control system to launch AIM-54 missiles, the tracking distance of this PDSTT is the farthest engagement distance of the AWG-9/AIM-54 system, and the tracking distance of PDSTT is more than 200 kilometers for targets with obvious radar reflection signals, such as Tu-95 and B-52; If the opponent is a fighter, such as a target such as the MiG-25, the tracking distance can also reach 150 kilometers, which is just the longest distance of the Immortal Bird missile.
If this system is installed on a MiG-25 fighter, Andrei is so excited that he can't sleep.
At this time, after hearing the report of the pilot in the rear cabin, George in the front cabin was a little puzzled in his heart, the altitude is sixteen thousand? According to the data we have, if it is a Tu-95, this kind of aircraft is a propeller aircraft! In previous reconnaissance, it was almost impossible to find that this kind of aircraft was flying at an altitude of more than 12,000! Now, the height of the other party is sixteen,000, a little strange, huh?
"The height is eighteen thousand, and the speed is nine hundred." The weapon operator in the rear compartment continued to report, at this time, the hearts of the two of them were full of uneasiness, damn it, I'm afraid it wasn't the Tu-95!
