Although it was improvised, the Tengfei Aviation Corporation, which had been pondering European anti-submarine equipment for a long time, still came up with an optimal combination plan.

At the heart of it are two parts, one is the integrated detection system at the front of the module, and the other is the magnetic anomaly detector that extends from the middle to the rear.

The integrated detection system is a retractable search radar equipped by the French Thomson company according to the French Navy's Atlantic anti-submarine patrol aircraft, and its technical blueprint is the AN/APS-38 sea-to-sea radar on the American S-2 anti-submarine patrol aircraft.

However, the space of the No. 02 anti-submarine belly boxed component itself is limited, and the retractable mechanism is somewhat complex and occupies space, so Tengfei Aviation Corporation did not inherit its retractable model, but after the fairing was aerodynamically optimized, it was fixed at the front end of the No. 02 anti-submarine belly boxed assembly.

The space saved was the installation of a compact acoustic detector and sonar receiver designed by the French company Thomson for unmanned anti-submarine aircraft.

The semi-cylindrical protrusion extending from the middle to the rear is a retractable magnetic anomaly detector, provided by British Space, and the source of technology is also from the United States, and the magnetic anomaly detector on the S-2 and S-3 anti-submarine aircraft is this retractable structure.

In the mid-70s, the British Gannet anti-submarine aircraft developed by the United Kingdom wanted to be upgraded, and one of the improvements was to install a set of retractable magnetic anomaly detectors similar to those found on the S-2 and S-3 anti-submarine planes in the tail.

The technology patents and samples have been obtained from the United States, and they are waiting for the British government to spend a small amount of money.

As a result, the British government at that time, under financial pressure, not only cut the upgrade plan of the gannet anti-submarine aircraft with a knife, but also cut the entire gannet anti-submarine aircraft fleet with the thought that it was not enjoyable.

In the face of the British government's desperate behavior of cutting leeks and cutting leek roots, British Aerospace can be said to have no tears, and the patents and samples bought at a large price are not used, so they can only be locked in the technical room and eat ashes.

I thought that this deal would be planted like this, but as a result, the actor company made an unmanned anti-submarine aircraft, and the British aerospace company saw what a good pick-up man, and without saying a word, the retractable magnetic anomaly detector that had fallen a layer of dust was turned out of the technical room, and after careful packaging, it was smashed into the actor company.

However, for the British Aerospace Corporation's chicken-like magnetic anomaly detector, it is a rare good thing for the Ascendas Aviation Corporation behind the Action Company.

Because there is no such thing, the boxed components under the belly of the No. 02 aircraft cannot be called anti-submarine mission components no matter how advanced they are, at most they can only be said to be patrol and reconnaissance components with anti-submarine properties.

The reason is very simple, just because the magnetic anomaly detector is the core detection equipment of the anti-submarine aircraft in addition to the acoustic detection system, and even in some specific environments, the magnetic anomaly detection equipment is more efficient and reliable than the acoustic equipment.

The reason for this is mainly due to the fact that the submarine can reduce its own acoustic signal by various means, but it is difficult to hide the all-metal shell in the earth's magnetic field environment, especially in the process of the submarine, the strong electromagnetic signal generated by magnetic cutting is difficult to completely cover.

It is based on this principle that the magnetic anomaly detector can accurately find the submarine hiding at the bottom of the sea in the vast ocean.

If there is no such equipment, only equipped with an acoustic system, it will not be so efficient, after all, the power of the sonar buoy dropped by the anti-submarine aircraft is not large, and it is also affected by the natural environment such as ocean clutter and ocean currents, and the accuracy is not high.

This is also the reason why the Soviet Tu-142 was not equipped with a magnetic anomaly detector, many people called it a long-range naval patrol aircraft, rather than an anti-submarine patrol aircraft, mainly because in addition to its large size and long range, the anti-submarine effectiveness of the Tu-142 is actually not high, and it is only one or two layers stronger than ordinary maritime patrol aircraft.

Because of this, without the retractable magnetic anomaly detector provided by British Space, the improved An-26 with the 02 component would be at the level of the Tu-142 on the technical path.

But with the magnetic anomaly detector, it is different, even if the interior of the An-26 cabin is so rough due to temporary modifications that even the seats are welded with steel bars and then covered with sponge cushions.

Not to mention the airtight equipment and air-conditioning equipment, there are no two hairs, and the concise is more touching than the clear water room of later generations, which fully embodies the unique character of the fighting nation that is simple but not simple.

Not to mention that compared with the cockpit of the comfortable and luxurious Plateau Eagle C, it is inferior to the second-class Plateau Eagle B.

But even so, the improved An-26 with the boxed components under the belly of the No. 02 aircraft can still be called an anti-submarine patrol aircraft, because the retractable magnetic anomaly detector can accurately detect 300 meters underwater, and with the front-end sea search radar, it can search within a radius of 200 kilometers.

Once a suspicious target is detected, ten active/passive sonar buoys on both sides of the assembly can be released for more accurate positioning of the submarine.

The reason why the Soviets' B-79 "Foxtrot" class conventional submarine and the Americans' "Shooting Fish" Sturgeon-class nuclear submarine were discovered was precisely due to the retractable magnetic anomaly detector in the boxed assembly under the belly of No. 02.

It's just that the anti-submarine crew commanded by Zhou Jiwei handed over the conventional submarines of the Soviets to the 5506 ship commanded by Chen Fang, and they concentrated on dealing with the American nuclear submarines.

As a result, Zhou Jiwei was so happy that he caught two submarines at once, and Song Changzheng lost all his good mood with a word that he didn't have the eyesight to see.

"Get your plane ready!"

Zhou Jiwei, who was exposed, knew that he was at a loss, so he simply didn't talk to Song Changzheng, and replied painlessly, and his expression was solemn: "Keep up the speed, the fish below is much more cunning than the one just now." ”

Song Changzheng didn't continue, after all, he was still on a mission, so he pouted and smiled, and then shook the control stick in front of him to keep the plane in a stable low-speed state.

At the same time, he turned on the intercom and was about to report the current mission situation to the flagship of the Eastern Union Fleet, but at this moment, Song Changzheng, who was just about to open his mouth to call, heard a murmur from the headset, which instantly covered the originally clear call.

For a while, several monitors in the engine room also flashed wildly like various convulsions, and Zhou Jiwei, who was still judging the location of the submarine, was stunned for a moment, and then frowned: "It's electronic interference again, is it endless?"
