Chapter 2040： Early warning aircraft?

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

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

In the U.S. Navy’s flight vehicles, there are still two fixed-wing propeller aircraft. One of the E-2 series of early warning aircraft is based on the improvement of products in the early 1960s, but until today, this early warning aircraft has The modification is still the most important aircraft in the US Navy's aircraft carrier battle group, and its status is irreplaceable.

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

The price is naturally the peak.

"And if you want to sell an early warning aircraft, maybe you can consider 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 wants an early warning aircraft? Why do they do it, their aircraft carrier will never go to sea once in a few years."

"Maybe it will be equipped with the nuclear-powered aircraft carrier of Charles de Gaulle in the future."

Yang Cheng nodded, "What about the price?"

"The current US price is 2.2 billion, including three E2D aircraft and supporting after-sales service!"

Yang Cheng smacked, "That's so expensive? I'll go, and I can't keep up with Yier's seventy-six pat."

"Yes, the unit price exceeds 700 million U.S. dollars, and the French can't afford it. Once the transaction is made, it will definitely break the record.

"Too expensive, too expensive, what is your own purchase price?"

"Um~ At present, the purchase price of the E-2D'Advanced Hawkeye' carrier-based early warning aircraft used by the US Navy is only 120 million US dollars."

Yang Cheng sighed and shook his head, "It's too profitable. It's too profitable. There are no friends at this price."

Demien laughed, "Why don't you have a friend? RB has just reached an early warning aircraft purchase agreement. It is expected to purchase 9 aircraft and deliver them next year. The unit price is only 340 million US dollars."

Yang Cheng nodded, "This price is barely acceptable. After all, it is impossible to use the same price as one's own. But if the French agreed to buy an early warning aircraft for 700 million, it would be really taken aback."

However, the Americans dared to raise this price also illustrates the superiority of the E-2D advanced Hawkeye carrier-based early warning aircraft. On the other hand, because there is only this fixed-wing carrier-based early warning aircraft in the world so far, the emperor’s daughter does not worry about marrying.

At present, one aircraft carrier in the US aircraft carrier battle 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 rare, but its role is very huge.

Due to the limitation of the curvature of the earth, no matter how advanced the performance of the ship-borne long-range air defense radar is, it is impossible to detect low-flying targets at a long distance. In the face of sea-skimming targets, the discovery distance of the ship-borne radar is often reduced to dozens. Kilometers.

Therefore, only a high-flying ship-borne early warning aircraft can detect long-range low-altitude targets, and can also rely on its altitude advantage to provide long-range air defense early warning like a beacon of a fleet.

Compared with early-warning helicopters, fixed-wing early-warning aircraft have much better 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 airborne early warning force.

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

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

In fact, although such radar technology seems backward today, it still barely can be used as an early warning aircraft.

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

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

Usually, the US military uses shipborne early warning opportunities to perform duties at an altitude of 30,000 feet (about 9,150 meters), which can give full play to the performance of early warning aircraft radar equipment.

The radar of the E-2D "Advanced Hawkeye" early warning aircraft is AN/APY-9 radar. This radar is a UHF band radar, that is, a low-frequency radar, which can provide a good effect on 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, as well as focus search on key directions.

It is generally believed that the AN/APY-9 anti-intercept radar used by E-2D has a target detection distance of 3~5 square meters, up to 550km, and can automatically suppress ground clutter and interference.

The APS-145 radar used in the E-2C era can track more than 2000 targets and guide 40 batches of aircraft to engage in combat. It is conceivable that the AN/APY-9 of E-2D should also It has been greatly improved, at least two generations advanced, it can be imagined that the capabilities of its electronic equipment are extremely powerful.

In addition, E-2D can form a network with other aircraft, battleships and sensor platforms through the data link. The addition of this two-way voice and data communication system can greatly expand the US military's ability to detect beyond the horizon.

The research and development technology of ship-borne fixed-wing early warning aircraft is very difficult. The main problem is how to maintain the performance of electronic equipment under the condition of limited size, but also to take off and land on the aircraft carrier and use it.

Therefore, this is why the technical level of E-2D is still leading the world. This early warning aircraft can theoretically carry out remote monitoring of sea aircraft, cruise missiles and even ground vehicles. It is E-2C and E-2D that constitute the US military aircraft carrier. The key force of long-range air defense early warning.

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 a fixed-wing carrier-based early warning aircraft. The model of this early warning aircraft may be "Air Police-600".

It is said that the size of the airframe is close to that of the E-2 early warning aircraft. The take-off weight is about 25 to 30 tons. It uses two propeller engines, which should be turboprop-6C engines ~ www.novelhall.com ~ Active phased array equipped with digital array Radar, the wing adopts a retractable folding wing design, the body structure strength is increased, and the installation is complicated with a four-vertical tail design.

In the future, after the Air Force-600 early warning aircraft is officially commissioned, it will significantly improve the air defense early warning detection capabilities of the Z aircraft carrier formation.

However, what Ah San needs seems to be a land-based early warning aircraft. The E-2D is a little overkill. After all, Ah San's broken aircraft carrier does not need such an advanced toy.

Of course, Asan local tyrants don't mind to equip them first.

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

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

Yang Cheng was speechless, "Sister, of course I know, but the price is too expensive, and A San is not that easy to fool, at least have to give them some thoughts?"

(Asan must pit! Not finished...)
