倘若让美军最顶尖飞行员驾驶的F-22中队，与解放军最精锐飞行员驾驭的J-20中队，在南海海域展开对决——胜负究竟会如何？

The American F-22 vs. Chinese J-20 is not even a close fight.
美国的F-22对决中国的歼-20，根本不是同一档次的较量。


The F-22 is the undisputed apex predator of the skies. The J-20 is a knockoff made in China. It's up to the pilot's skill. American pilots get tons of flight time, training, and all that, while the Chinese conserve fuel and watch Top Gun movies back at base.
F-22是当之无愧的制空霸主；歼-20只是中国的贴牌仿制品。一切取决于飞行员水平——美国飞行员拥有大量飞行时间和训练机会，而中国飞行员则节约燃油，在基地里看《壮志凌云》。

In 2024? The J-20. Oh sure the F-22 is a formidable machine.
2024年对决？歼-20更胜一筹。诚然，F-22也是一款强悍战机。

But over the F-22 it loses pretty much EVERY single advantage.
但相较F-22，歼-20几乎在每个方面都占优。

On top of this. In 2024 USAF pilots actually have less flight hours than Chinese or Russian pilots. USAF pilots get 8–10 hours of flight a month. Chinese pilots get about 170 a year, Russian pilots get about 150+ actual combat missions flown now.
更何况，2024年美空军飞行员的月飞行时数只有8–10小时，而中国飞行员年均约170小时，俄方甚至执行了150多次实战任务。

Westerners are under the impression a stealth aircraft can literally turn completely invisible to radar and be undetected, hence why they regularly talk about how a B21 can bomb Beijing with impunity.
西方人普遍存在一种误解，认为隐身战机真的能在雷达面前彻底"消失"，正因如此，他们时常鼓吹B21轰炸机可以肆无忌惮地空袭北京。

The F-22 has to take off from the ground—There’s literally very few places it can take off from. So we know where they will come from.
F-22只能从陆基机场起飞，起飞场所极其有限，所以我们能锁定它们的出发地点。

We have massive multi band radar on the ground to locate the F-22s.
我们在地面部署了多频段远程雷达，用来追踪F-22。

We have satellite surveillance of the entire area and have demonstrated tracking F-22s visually from satellites.
我们拥有全覆盖卫星监视，且已展示过用卫星目视追踪F-22的能力。

It’s over water meaning there’s literally nowhere to hide or terrain that can be used for defence.
海上作战意味着没有地形可借以隐蔽或掩护。

As such the J-20 can just sit back and lob PL-17s at the F-22s. As above we have plenty of ground based radars from multiple directions using different bandwidths. J-20 has 4 of them. They could literally take off, lob missiles, land, rearm, lob some more, land, re-arm and lob some more. Cowardly? This is literally a USAF technique I remember a fighter pilot talk about on here. TBJF - Turn and burn Jet fuel. Loose some 2 AMRAAMS per target. Then turn around rinse and repeat.
因此，歼-20只需待机，然后不断向F-22投掷PL‑17导弹。我们四面部署了多频段地面雷达，J-20上配备了四台接收器。它可以不停地起飞—发射—着陆—补给—再发射，循环往复。说它懦弱？这正是美空军飞行员自曝的战术：“TBJF”（加油冲刺），每次向目标发射两枚AIM‑120，之后掉头再来。

The Raptors will fly from Philippines and South Korea and Aircraft Carriers
猛禽（F‑22）将从菲律宾、韩国和航母上起飞。

The first interception will be with the JH-7
第一道拦截将由JH‑7执行。

They will be the first line in Chinese Air space
它们将构成中国领空的第一道防线。

Then the HQ9 will launch missiles towards the Raptors
随后HQ‑9地对空导弹会对F‑22发起攻击。

This will be the second line
这就是第二道防线。

Finally the S-400 will get a lock and go after the Raptors
最后，俄制S‑400系统会锁定并打击F‑22。

The Raptor will never face off against a J-20 in the South China sea
F‑22在南海绝不会与歼-20正面交锋。

Not unless it's a Top Gun movie
除非是在电影《壮志凌云》中。

In fact using the Raptor against China is stupid in the first place
实际上，用F‑22对付中国本身就是不明智的选择。

Both the Raptor and the J-20 are primarily meant to destroy ground targets
F‑22和歼-20都主要定位为对地攻击机。

This means they aren't built for air to air combat
这意味着它们并非为空战而生。

They aren't that maneuverable
它们的机动性也有限。

When will the J-20 and Raptor face off?
歼-20和F‑22究竟何时会交手？

Somewhere in the middle of the Ocean where China and US have Aircraft Carriers and the planes fly off from ACCs and fight with each other
也许是在太平洋某片海域，中美航母战斗群正严阵以待——舰载机从航空母舰（ACCs）呼啸升空，即将展开一场激烈的空中对决。

Say hypothetically China sends a Naval Carrier Fleet to Australia and US intercepts the same
比如假设中国派航母舰队前往澳大利亚，美方舰队拦截。

Otherwise the Raptor will face off against the JH-7 & HQ-9 & S-400
否则F‑22将对抗JH‑7、HQ‑9和S‑400。

Likewise the J-20 if it flies against Taiwan will likely face the A-IDF Taiwanese fighters & F-16Vs
同理，歼-20若对台作战，将面对台湾（地区）的经国号（A‑IDF）、F‑16V战机。

Not the Raptors or even the F-35s
而非F‑22或F‑35。

Anything could happen but my money is on the F-22 squadron. I think the F-22’s superior stealth, engines, and radar give it a big advantage over the J-20 and the F-22 also carries more A2A missiles. The F-22 was meant for air-superiority, the J-20 is an interceptor so it’s not a favorable matchup. The J-20 is meant to chase down AWACS, Tankers, Transports, those high value targets.
一切皆有可能，但我押注于F‑22中队。我认为F‑22更出色的隐身性能、发动机推力和雷达都胜过歼-20，而且它携带更多的空空导弹。F‑22定位制空战机，而歼-20则是拦截机，不是对等较量；歼-20的任务是追击预警机、加油机、运输机等高价值目标。

Probably the biggest advantage for the F-22 is the Americans have been operating stealth aircraft decades longer than China has. The former not only has significantly more experience operating stealth, but tracking and engaging stealth as well. The F-22 just has many things going for it and that’s not including the new helmets and missiles it’s received.
F‑22的最大优势还在于美军隐身机运营历史远比中国长数十年；美军不仅在隐身机操作方面经验丰富，也擅长追踪和对抗隐身目标。除此之外，F‑22还装备了新型头盔和导弹。

I think this is how an F-22 vs J-20 would go
我想，这就是F‑22对阵歼-20的想定战果。

Wow, really trying to stoke the controversy aren't you? The real answer is, no one wins, because they don't fight. The US and China both have nuclear weapons and the capability to deliver those weapons to the other country. Both countries will instruct their pilots to avoid a conflict.
哇，真是火上浇油。我来告诉你真正答案：没人能赢，因为他们不会开战。中美都握有核武器且具备对对方的打击能力，双方都会指示飞行员避免爆发冲突。

However, if you must have the rah-rah war and bloodshed answer, then the Americans probably win. The F-22 is significantly stealthier than the J-20, it likely has a significantly better radar, and significantly better avionics. American pilots are also probably more experienced and more well trained than their Chinese counterparts. Additionally, the J-20 doesn't really appear designed for the air superiority mission. It appears to be designed as more of a long-range sniper, meant to take out support aircraft like AWACs and tankers, not mix it up in air combat with other fighters. All that adds up to an American advantage that would likely win them any hypothetical fight.
但如果非要一场扬眉吐气的“血战”来回答，那美军大概胜算更大。F‑22隐身性能更佳，雷达和航电优势明显，美军飞行员也更资深、训练经验更丰富。此外，歼-20并非定位制空战机，更像远程“狙击手”，主要对付预警机和加油机，不擅长与其他战机缠斗——所有这些都让美军在假想战中占优。

OP: A squadron of F-22 with the best American pilots vs a squadron of J-20 with the best Chinese pilots, over the South China sea? Who wins?
楼主问：在南海上空，由最优秀的美军飞行员驾驶F‑22中队对抗最顶尖的中方飞行员驾驶的歼-20中队，谁能胜出？

The US.
美国。

The biggest disadvantage China faces is that the J-20 are ground-based and are not yet ready to be deployed on aircraft carriers, and we don’t yet know if J-20 can be launched repeated from aircraft carriers, even with China’s unreliable electro-mag launcher. This is the reason why the F-22 isn’t carrier based. Its airfrx and coating may not survive repeated catapult launch. Combined with PLAF’s lack of experience with mid-air refueling J20. it means a limited range for J2- and a predictable RTB path pre and post combat. Predictability is how you get killed.
中国的最大劣势在于歼-20仍是陆基机，不具备成熟的航母适配能力；即便使用尚不稳定的电磁弹射，也不知能否重复运作。这也是F‑22从未航母化的原因——其机体和涂层或难以承受多次弹射。加之中空加油经验不足，歼-20的战斗半径受限，返航路径可预测，而“可预测”即会被击杀。

The second biggest disadvantage China faces is the lack of an integrated sensor net. If the engagement is close to China’s shoreline, there is a higher chance the F-22 would be without its normal combat support assets, like the AWAC, but it also means the J-20’s will also be more visible to the F-22. It’s a matter of energy, the J-20 is less stealthy than the F22, so even as J-20 might have a sensor advantage over the F-22 the closer the combat is over China, it also means the J-20 will reflect greater radar energy for the F-22 to pick up.
中国的第二大劣势是缺乏一体化的传感器网络。若对抗发生在中国海岸附近，F‑22或将面临缺少预警机等支援资产的情况，但这也意味着歼-20暴露度更高。能量管理上，歼-20隐身性能逊于F‑22，近岸作战时反射的雷达能量更容易被F‑22捕捉。

Doctrinally, US would not fight an squad on squad battle. AWAC would have alxed the fighter wing and the US airfrxs would have launched BVR and let the networked sensor and radar system guide the missiles into the basket. US fights systematic war, has been, ever since the first Gulf war, it’s just too bad they don’t have any worthy enemies.
从作战原则来看，美军不会以中队对中队硬碰硬。预警机会提前警报，战机发射超视距导弹，由网络化传感与雷达系统指引“射中靶心”。美军自海湾战争以来一直打系统化战争，只可惜敌人寥寥。

There are likely 10 times as many F-35s as F-22s in South Korea, Japan, and on the oceans on US CATOBAR supercarriers and smaller attack carriers from the US and Japan.
在韩国、日本乃至美日航母（尤其是搭载滑跃/弹射系统的航母）上，F‑35的部署数量很可能是F‑22的十倍。

F-22s might play a small part in a war near the Chinese coast. The US would depend on launching missiles from land bases, submarines, carrier battle groups, miscellaneous destroyers, B-52s, B-1Bs, soon to be B-21s, and B-2s.
F‑22在中国近海战事中或仅担当小角色。美军将主要依赖陆基导弹、潜舰、航母战斗群、驱逐舰、B‑52、B‑1B、未来的B‑21和B‑2等平台发射导弹。

Some Japanese, US, South Korean, and Taiwanese fighters might also launch missiles at Chinese boats and islands in the South China Sea or close targets like those a hundred miles from Taiwan. Other countries like Australia might join the fight.
日韩、美台战机或也会对南海的中国舰船、岛礁，乃至距台百余海里的目标实施导弹打击。澳大利亚等国也可能参与行动。

The more time that goes by, the larger number of F-35s and B-21s will become available. F-22s would be better used to defend Alaska, Hawaii, Guam, and some of the West Coast of the US.
随着时间推移，可投入战场的F‑35和B‑21数量将持续增加，F‑22更适合驻防阿拉斯加、夏威夷、关岛及美国西海岸。

If China starts bombing US or US allies’ bases in a big way, it would be an invitation to nuclear war. It is clearly better that neither side starts this war.
若中国大规模轰炸美国或其盟友基地，无异于自招核战争。显然，双方都不应首先发动此战。
