"Cheap? Then don't think about it. Il 76 is 5 times more expensive, and it is cheaper than E2D."

The current mainstream early warning aircraft in the United States is E2D, and there is no other option.

Two fixed-wing propeller aircraft are still retained in the US Navy's flight vehicles. Although one of the E-2 series early warning aircraft is improved based on products from the early 1960s, to this day, the modification of this early warning aircraft is still the most important aircraft in the US Navy's aircraft carrier battle group, and its status is irreplaceable.

The latest improved E-2D "Advanced Hawkeye" of the E-2 series can be regarded as the pinnacle of carrier-based early warning aircraft.

As for the price, it is naturally the peak.

"And if you want to sell early warning aircraft, you may think about the French again. They also want to buy it, but because the price remains high, the agreement has never been reached."

Yang Cheng was stunned, "France also needs an early warning aircraft? Why do they use it? Their aircraft carrier will not go to sea once every few years."

"Maybe it is for the future to be equipped with the USD Charles de Gaulle nuclear-powered aircraft carrier."

Yang Cheng nodded, "Where is the price?"

"The current price offered in the United States is 2.2 billion, including three E2Ds and supporting after-sales service!"

Yang Cheng smacked her tongue, "It's so expensive? I'll go, I'll be able to catch up even if I slap in the seventeenth place."

"Yes, the unit price is more than 700 million US dollars, and the French cannot bear it. Once the transaction is completed, it will definitely break the record."

"It's too expensive, how much is your own purchase price?"

"Well~ The US Navy's E-2D 'Advanced Hawkeye' carrier-based early warning aircraft is currently only US$120 million."

Yang Cheng sighed and shook his head, "It's too profitable, too profitable, there's no friend in this price."

Demien laughed, "Why don't you have friends? RB just reached an early warning aircraft purchase agreement, and it is expected to purchase 9 aircraft, and it will be delivered next year, with a unit price of only US$340 million."

Yang Cheng nodded, "This price is barely acceptable. After all, it is impossible to be the same as your own. But if the French agree to buy an early warning aircraft for 700 million yuan, it would be a big mistake."

However, Americans dare to buy this price, which also indirectly illustrates the superiority of the E-2D advanced Hawkeye carrier-based early warning aircraft. On the other hand, it is because there is only this fixed-wing carrier-based early warning aircraft in the world so far, so the emperor's daughter does not have to worry about marriage.

At present, an aircraft carrier of the US aircraft carrier combat group will be equipped with at least one early warning aircraft squadron, that is, 4-5 fixed-wing early warning aircraft, to provide vital air defense early warning assistance.

Although the number is very small, its role is very huge.

Due to the limitation of the Earth's curvature, no matter how advanced the performance of the carrier-based long-range air defense radar is, it is impossible to discover low-altitude targets at long distances. Faced with the targets of seafly flight, the discovery distance of the carrier-based radar is often reduced to dozens of kilometers.

Therefore, only high-flying carrier-based early warning aircraft can detect long-range low-altitude targets, and can also rely on their altitude advantages to provide long-range air defense early warnings like a fleet's lighthouse.

Compared with early warning helicopters, the fixed-wing early warning aircraft have much better air stagnation time, speed and electronic equipment performance. Therefore, the US aircraft carrier battle group now relies on E-2C or E-2D to form a carrier-based air early warning force.

The E-2 series early warning aircraft first appeared in the US military's early warning aircraft program in the late 1950s. The first E-2A early warning aircraft was delivered in January 1964, thus opening up the history of the E-2 series for more than half a century.

The original E-2A used AN/APS-96 radar that could track 250 targets and guide 30 fighters to engage in combat. At that time, its radar detection range was 370 kilometers.

In terms of xiong, although such radar technology seems to be behind today, it can still be used as an early warning aircraft.

The improvements of the E-2 series focus on the improvement of the body's electronic equipment. Today's E-2D "Advanced Hawkeye" has little difference in pneumatic appearance, but the internal electronic equipment has long reached the world's top level.

Since it is a fixed-wing propeller aircraft, the E-2D is not fast, with a maximum speed of about 648 km/h and a cruising speed of 474 km/h. When there is no air refueling, the air stagnation time is more than 7 hours, and when there is air refueling, it can reach up to 12 hours.

Usually, the US military uses a ship-based early warning opportunity to work at an altitude of 30,000 feet (about 9,150 meters), which can exert the performance of the radar equipment of the early warning aircraft.

The radar of the E-2D "Advanced Hawkeye" early warning aircraft is AN/APY-9 radar, which is a UHF band radar, that is, a low-frequency band radar, which can provide good results for the discovery of stealth aircraft.

At the same time, the AN/APY-9 radar adopts a combined detection mode of "electronic scanning + mechanical scanning", which can perform all-round 360-degree scanning, and can also conduct key searches on key directions.

It is generally believed that the AN/APY-9 used by E-2D can reach more than 550km in the target detection distance of the interceptor transmission surface of 3~5 square meters, and can automatically suppress ground clutter and interference.

As early as the APS-145 radar used in the E-2C era can track more than 2,000 targets and guide 40 batches of aircraft to engage in combat. It is conceivable that the E-2D's AN/APY-9 should have been greatly improved on this basis, at least two generations advanced, and it is conceivable that the capabilities of its electronic equipment are extremely powerful.

In addition, E-2D can be connected to other aircraft, warships and sensor platforms through data links. The addition of this two-way voice and data communication system can greatly expand the US military's super horizon detection capabilities.

The research and development technology of carrier-based fixed-wing early warning aircraft is very difficult. The main problem is how to maintain the performance of electronic equipment while the volume is limited, and it also takes into account the take-off and landing and use on aircraft carriers.

Therefore, this is why the technical level of E-2D is still ahead of countries around the world. This early warning aircraft can theoretically conduct long-distance monitoring of maritime aircraft, cruise missiles and even ground vehicles. It is E-2C and E-2D that constitute the key force for long-range air defense warning of US aircraft carriers.

Except for the United States, no country has independently developed and actually equipped fixed-wing carrier-based early warning aircraft.

Only Country Z is independently developing fixed-wing carrier-based early warning aircraft, and the model of this early warning aircraft may be "KJ-600".

It is said that the size of the fuselage is relatively close to that of the E-2 early warning aircraft, with a take-off weight of about 25 to 30 tons. Two propeller engines should be turboprop-6C engines, equipped with a digital array active phased array radar, the wings adopt a rear-retractable folding wing design, the body structure is increased, and a complex four-sided tail design is installed.

In the future, after the KJ-600 early warning aircraft is officially put into service, it will significantly improve the air defense early warning detection capabilities of the Z aircraft carrier formation.

However, what A San needs seems to be a land-based early warning aircraft, and the E-2D is a bit useless. After all, A San's broken aircraft carrier does not need such advanced toys.

Of course, the rich man of A San doesn’t mind getting equipment first, so that’s another matter.

"Demion, the E2 early warning aircraft should have a land-based model, right? A San's aircraft carrier is still used as a model exhibition in the factory, and the sea-based model is not used."

"E2D can fully undertake land-based early warning tasks~"

Yang Cheng was speechless, "Sister, of course I know, but the price is too expensive. Ah San is not that easy to fool. At least he has to give them some thoughts, right?"
