Here's how the US' F-22 Raptor compares to China's J-20 stealth fighter
美國F-22猛禽戰鬥機與中國殲-20隱形戰鬥機對比
China's new J-20, officially named Weilong or powerful dragon, is one of the world's most advanced fighter jets and the country's answer to the American F-22 Raptor.
中國的新型殲-20，官方命名為「威龍」，是世界上最先進的戰鬥機之一，也是中國對美國F-22猛禽的回應。
In mid July the PLA Airforce released a video of a nighttime training exercise involving the stealth fighter as a demonstration of its combat readiness.
7月中旬，中國人民解放軍空軍發布了一段隱形戰鬥機夜間訓練的視頻，展示其戰備狀況。
The Chinese warplane was developed by the Chengdu Aerospace corporation, which began testing them in 2011 before the first planes entered service in March 2017.
這架中國戰機是由成都航空航天公司研發的，該公司從2011年開始試飛，直到2017年3月首批戰機開始服役。
So far a few dozen J-20s have been produced for the PLA although the manufacturer is continuing to build more.
到目前為止，該廠已經為中國人民解放軍生產了一批殲-20，目前還在繼續生產。
The F-22 Raptor was developed by Lockheed Martin for the exclusive use of the US Air Force. Exports even to America's closest allies are banned to protect its stealth technology.
F-22猛禽戰鬥機是由洛克希德·馬丁公司為美國空軍獨家研發的。為保護其隱形技術，該機型就算對美國最親密的盟友也禁止出口。
Its maiden flight was in September 1997 and it entered service in December 2005. In 2011 production was terminated because of the high costs involved and lack - at the time - of any aircraft that could challenge its dominance.
它於1997年9月進行首飛，並在2005年12月開始服役。由於成本高昂且當時沒有任何飛機能夠撼動其統治地位，2011年開始停產。
America is planning to upgrade the fighter in future but for now it remains, along with the Weilong, one of the most advanced fifth generation fighters in the world.
美國計劃在未來升級F-22猛禽戰鬥機，但目前它和威龍一樣，是世界上最先進的第五代戰鬥機之一。
Both single-seat fighters have stealth capabilities, which means they are designed to avoid detection by radar.
這兩種單座戰鬥機都有隱形能力，這意味著可以避免被雷達探測到。
Here is how the two compare.
以下是兩者的對比。
Design characteristics
設計特點
The J-20 and F-22 are a similar size. The J-20 is 20.3 metres (66.6ft) long and has a 12.9 metre wingspan compared with the F-22's 19m length and 13.6m wingspan.
J-20和F-22大小相似。J-20長20.3米(66.6英尺)，翼展12.9米，而F-22長19米，翼展13.6米。
Made of advance alloy materials, they also have similar empty weight of around 19,000kg.
都是由先進的合金材料製成，淨重也相近，都是約19000公斤。
The J-20's loaded weight is slightly heavier, of around 32,000kg compared with the F-22's 29,000kg, however the American fighter can take off with a maximum weight of 38,000kg, 2,000kg more than the J-20.
J-20裝載的重量比F-22的29000公斤稍重，約32000公斤，然而美國戰鬥機最大起飛重量38000公斤，比J-20多2000公斤。
Performance
性能
Both planes have a ceiling of 20km and a maximum speed of over Mach 2 (2,470km per hour) - faster than the speed of sound. The F-22 has a comparatively shorter range - with a combat radius of 800km, while the J-20's large internal fuel tank can sustain a longer combat radius of 1,100km.
兩種飛機的最大飛行高度都為20公裡，最高時速超過2馬赫(每小時2470公裡)——比音速還快。F-22的作戰範圍相對較小——半徑戰鬥800公裡，而J-20內部的大型燃料箱可以續航1100公裡。
Engine
引擎
The F-22 is powered by afterburning turbofan F119-PW-100 engines, which enable it to super cruise at a speed of Mach 1.82. The engines have vectoring nozzles which enable it to perform agile manoeuvres event at supersonic speeds.
F-22由F119-PW-100後燃渦輪風扇發動機提供動力，使其能夠以1.82馬赫的速度進行超級巡航。發動機有矢量噴口，使它能在超音速時進行敏捷的操縱。
However, the engine is the J-20's weakest link. Plans for China to develop its own advanced turbofan engines fell behind schedule. This meant the manufacturers had to rely on inferior engines - either the Chinese WS-10B or Russian-made AL-31FM2/3 - which severely affects its manoeuvrability and stealth capacity at supersonic speeds.
然而，發動機是J-20最薄弱之處。中國自主研發的先進渦輪風扇發動機的規劃落後於計劃。所以製造商不得不使用次級發動機——無論是中國的WS-10B還是俄羅斯製造的al - 31fm2 -3，都嚴重影響了J-20在超音速行駛時的機動性和隱身能力。
However, the new WS-15 engine, which is expected to be available next year, will go a long way to addressing this problem.
不過，新的WS-15引擎預計將在明年推出，它將在很大程度上解決這個問題。
Stealth
隱形
The J-20's frontal and side stealth capacities are believed to be excellent. But it is thought to be more vulnerable to radar from the rear compared with the F-22.
J-20的正面和側面隱形能力是優秀的。但與F-22相比，它更容易被後方雷達探測到。
Armaments
武器
To maintain stealth, both fighters carry their weapons in internal bays. The J-20 can carry up to six air-to-air missiles, fewer than the F-22. But thanks to larger space in each bay, the J-20 can carry longer range missiles and the LS-6 precision-guided bomb.
為了保持隱形效果，兩架戰鬥機都利用內部的彈倉攜帶武器。J-20可以攜帶6枚空對空飛彈，比F-22少。但是由於每個彈倉的空間更大，J-20可以攜帶遠程飛彈和LS-6精確制導炸彈。
So far it has not been confirmed to have any guns, although some analysts believe it would be able to carry extended guns.
到目前為止，它還未被證實擁有任何槍炮，但有些分析人士認為它可以攜帶擴展槍枝。
The F-22 can hold up to eight short or medium-range air-to-air or air-to-ground missiles. It also has an M61 Vulcan gun in addition to four under-wing drop tank points, which allow it to carry extra fuel or missile launchers.
F-22可攜帶8枚短程或中程空對空或地對地飛彈。它還有一門M61火神炮，另外在四個機翼下方的還有空投點，可以攜帶額外的燃料或飛彈發射器。
Avionics
航空電子設備
Both aircraft possess highly integrated avionics and sensor equipment, featuring a low-observable, active electronically scanned array (AESA) that can track multiple targets in any weather.
這兩架飛機都擁有高度集成的航空電子設備和傳感器設備，配備了低可探測度、主動電子掃描陣列(AESA)，可以在任何天氣下追蹤多個目標。
It was reported by Shenzhen TV that the J-20's Type AESA radar system is "totally similar" to the F-22's AN/APG-77 system.
據深圳電視臺報導，J-20型AESA雷達系統與F-22的AN/APG-77系統幾乎「完全相似」。
Cost
成本
The F-22 production was axed because of its high cost - US$62 billion for the whole project, which equates to US$339 million per aircraft.
F-22的生產被取消了，因為它的成本非常昂貴- - -整個項目花費了620億美元，相當於每架飛機3.39億美元。
The J-20's research and development cost was estimated to be more than 30 billion yuan (US$4.4 billion), with a cost per aircraft of US$100-110 million.
J-20的研發成本估計超過300億元(44億美元)，每架飛機的成本為1 - 1.1億美元。

Painting a jet black does not constitute "stealth" technology. However, what I'm worried about is GE and Boeing sending commercial jets their way... (In case for some of you who don't know...GE makes high-end jet engines with high output and efficient fan blades.)
把飛機噴稱黑色並不意味著就「隱形」了。不過，我擔心的是通用電氣和波音公司用他們的方式輸送商業飛機……（你們中有些人可能不知道……通用電氣製造高端噴氣發動機，擁有大功率輸出和高效的風扇葉片）

The canards on the J-20 are not especially stealthy. But the main advantage of this class of fighters is the electronics. If the F-22 detects the J-20 first it's pretty much game over.
J-20上的鴨翼不是特別隱蔽。但是這類戰鬥機的主要優勢是電子設備。如果F-22首先檢測到J-20，那就差不多結束了。

As we saw in the first gulf war, it does not come down to fighter jets engaging in a dog fight. You must look at the entire air defense system. An enemy is not facing a lone squadron of F-22's. It is facing our top of the line fighter jets in front followed by a whole host of support aircraft- radar jammers, F-16's, and an AWACS monitoring the whole situation. We win.
正如我們在第一次海灣戰爭中所看到的，戰鬥機空中混戰並不是根本。你必須著眼於整個防空系統。一個敵人並非只面對一個F-22中隊。它面對的是我們的頂級戰鬥機，已經後面跟著的大批支援飛機——雷達幹擾機、F-16戰鬥機和監控整個戰局的預警機。我們贏了。

Right now the J-20 would be used as an interceptor due to its long legs, not really a fighter. The author tossed a hypothetical in on the W-15 engine in that he assumes it will function properly despite the fact that China has an extremely long history of having issues developing and building Jet engines.
目前J-20因為它的長腿，將被當成攔截機使用，而不是真正的戰鬥機。作者對W-15引擎提出了假想，認為儘管中國在研發、製造噴氣發動機方面一直存在問題，但W-15引擎還是會表現出色。

No comparison at all. That Chinese POS will probably break apart the first time they have to make a high G turn. Not even in the same league as the F-22.

In reality NOBODY truly knows for sure how they compare because the two have never faced off in the real world. But since virtually EVERYTHING China has is reverse engineered from what they steal from us odds are pretty damn good it's a pitiful copy at best.
事實上，沒有人能真正確切地知道他們比較起來怎麼樣，因為他們在現實世界中從來沒有對峙過。但由於中國幾乎所有的東西都是逆向工程的結果，他們從美國偷來的東西可能非常好，但這個飛機充其量不過是一個可憐的複製品。
