F-15鷹式戰鬥機（F-15 Eagle），是一款美國開發生產的全天候、高機動性的戰術戰鬥機。以及針對獲得與維持空優而設計的它，是美國空軍現役的主力戰鬥機之一。F-15是由1962年展開的F-X（Fighter-Experimental）計劃發展出來。在戰鬥機世代上，按照原先的歐美標準被歸類為第三代戰鬥機與F-16，法國的幻象2000，俄羅斯的米格-29、米格-31、Su-27、Su-30、Su-33、，中國的J-10等是同一世代。

外傳美國同意租借給台灣空軍60架,退役型F15/CD.型戰鬥機以取代老化的Mirage2000E,台美對於戰機採購已有初步討論，名單包括二手F-15C/D型戰機、F-15 2040C型戰機、F-18E/F超級大黃蜂戰機，或最新升級版的F-18XT戰機。,

台灣方面想買F-15戰機，主要是因為具有高空高速攔截性能優異、作戰半徑較大等優點，但F-18戰機被指與IDF戰機有許多通用的零組件，而且F-18具備更強的電子戰設備，雖然F-18的航程較短，但是在台海空域運用，反而有更大的優勢。

你們台灣以為佔到優勢與便宜,豈知道你們台灣要花大筆的維修費與提升F-15C/D航電系統及通訊系統的電腦.甚至於整體改裝的費用因為美國自從2015年起陸續淘汰退役150架的F-15C/D.你們台灣永遠是撿破爛美國不要的武器,F-15C/D 要改裝升級多功能的航電系統包含了抬頭顯示器（Head-Up Display，HUD）、先進的雷達、慣性導航系統（Inertial Navigation System，INS）、 飛行儀表、超高頻（Ultra-High Frequency，UHF）通訊、戰術導航系統與儀器降落系統（Instrument Landing System，ILS）。

Taiwan could soon lease U.S. F-15 air superiority fighters.

Taiwan’s Up Media reported on Mar. 19 that Washington has proposed to lease instead of selling F-15 fighter jets to the island.

According to Alert 5 Weblog, the potential deal is a win-win for both parties as America is unwilling to sell the Eagle to Taiwan and the latter might not be able to afford buying new F-15s in large quantities.

The proposal is to lease aircraft that still have half of their lifespan remaining and upgrade them with new mission computers and fire control radars.

Taiwan had previously leased 40 T-38 advanced jet trainers in the last century as well as Knox-class warships.

As we have previously reported the Republic of China Air Force (ROCAF) was evaluating a plan to buy the Boeing F-15 or F/A-18 not only as a replacement for the Mirage 2000 but also to “strengthen its defense capabilities and counter China’s Russia-made Sukhoi Su-30 fighter aircraft. The report said Taiwan and the U.S. have had preliminary discussions about the purchase, and retired models such as the F-15C/D or new models like the F-15 2040C, the F-18E/F and the F-18XT have all been mentioned.”

However Taiwan interest in Boeing fighters comes as a total surprise.

In fact as we previously reported, on Apr. 5, 2017 an official from Taiwan told the Foreign Affairs and National Defense Committee that the island welcomes the sale of the F-35 stealth fighter. Taiwan was looking for a fighter with short-take off and vertical-landing (STOVL) capabilities, hence the need for the “B” variant of the F-35. But, although it is possible that the Lockheed Martin F-35 could be sold to Taiwan, the island might not be able to afford buying the stealth fighter hence it could buy legacy fighters such as F-15s, F/A-18s or more F-16s.

它也內建了戰術電戰系統、敵我識別器（Identification Friend of Foe，IFF）、電子反制（Electronic CounterMeasure，ECM）裝置與中央數位電腦系統。 

而經過MLU工程改進的台版F-15C/D，性能約等於日本航空自衛隊使用的F-15J/DJ/EJ的MSIP（多階段改良計劃）的水準。日本專家揭露早期型的F-15J/DJ「鷹」式戰機因航電系統落伍已無法勝任前線任務，建議將半數F-15提前退伍並增購F-35A「閃電二式」

 根據消息表示，考慮台海的政治敏感度、台灣空防的迫切需要以及美中關係的敏感性，美國極可能以“剩餘國防物資”（ Excess Defense Articles, EDA）的方式，將美國空軍剛剛退役的F-15C/D型中古戰機，以“租借”方式給予台灣，此動作既可避免台美中的高度政治敏感性，也可以在短時間極大地加強台灣空軍高空高速攔截的能力，同時也可以讓台灣即有限的國防預算，在采購高價新戰機這個難題上，得到解套
