The U.S. Air Power inducted its first fourth technology fight plane, the F-15 Eagle heavyweight fighter into service in 1976, offering a really signifiant enchancment over the prior Vietnam Battle period technology the place the F-4E Phantom had represented the service’s heaviest and most generally used fighter. The F-15’s efficiency was far forward of the F-4 throughout the spectrum, from velocity and altitude to endurance, situational consciousness and most drastically its manoeuvrability at each excessive and low speeds, whereas the fighter additionally carried eight air to air missiles up from the Phantom’s unique six. The Eagle had one main shortcoming relative to the Phantom, nevertheless, which was its a lot increased operational prices and upkeep necessities. Whereas the F-4 was a really costly plane to function for its time, and consequently noticed comparatively few exports with most shoppers being delivered the cheaper and lighter F-5, the U.S. Air Power may nonetheless afford to kind the spine of its fleet utilizing the fighters. This was not the case for the F-15, nevertheless, which required the Air Power to accumulate a lighter and cheaper fighter in parallel and in a lot bigger numbers – the F-16 Preventing Falcon. 

The F-16 used the identical F110 engine because the F-15, however in single moderately than twin configuration which means it had solely half the thrust. Its radar was significantly smaller and weaker, akin to that of the Soviet MiG-23ML that had entered service, however the fighter itself couldn’t fly anyplace close to as excessive or as quick because the MiG-23 not to mention the F-15. The F-16’s endurance however exceeded that of the F-4, and whereas slower and unable to fly as excessive it in any other case improved on the Phantom in all areas of efficiency together with by way of upkeep necessities and operational prices. The F-16 and F-15 have been thus extremely complementary, with the previous submitting out most models and offering a considerably unremarkable however nonetheless sturdy functionality for air to air fight, whereas the latter fashioned elite models tasked with partaking essentially the most succesful fighters in an enemy air pressure and if wanted penetrating deeper into enemy airspace. This was mirrored within the roles the 2 have been assigned within the U.S. Air Power’s first main post-Vietnam air marketing campaign, Operation Desert Storm in opposition to Iraq in 1991, which noticed the extra quite a few F-16s held again from any engagements in opposition to Iraqi prime finish MiG-25 interceptors and MiG-29 fighters whereas the F-15s have been tasked with tackling these extra plane. The F-16 would doubtless have struggled in opposition to each of them regardless of the prevalence of American pilots and their entry to assist from E-3 AWACS jets which the Iraqis lacked. 

The F-15’s elite standing was additionally mirrored by its armaments, with the F-16 for years supplied no past visible vary air to air missiles which means even in opposition to Soviet third technology jets reminiscent of MiG-23s it confronted a big drawback. When F-16s started to belatedly discipline AIM-7 Sparrow missiles, offering semi energetic radar steering, the F-15 was already set to deploy the far more succesful AIM-120 with energetic radar steering. Many F-16 models operated for years and even many years with no past visible vary capabilities. 

The F-15 and F-16 are the oldest fighters on the earth to nonetheless be in manufacturing as we speak, albeit primarily for export and within the F-16’s case largely to much less developed American defence shoppers with smaller budgets reminiscent of Bahrain, Slovakia and Bulgaria. The F-16 noticed a manufacturing run of over 4,500 by 2010, with the producer Lockheed Martin expressing confidence in 2020 that the fighter may exceed 5000 models. There have been indictions in early 2021 that the U.S. Air Power may resume F-16 purchases as a consequence of main points with its substitute program the F-35, though later statements by officers indicated this was unlikely to materialise with a rising variety of defence officers in each the U.S. and overseas highlighting that the Falcon would very quickly be out of date. The manufacturing determine for F-16s excludes the Japanese F-2, which may be very intently primarily based on the F-16 however with a lot increased use of superior composite supplies, bigger wings and completely different avionics and sensors. The F-15, in the meantime, has seen roughly 1,700 constructed – round 500 of that are derivatives of the F-15E Strike Eagle variant. Each fighters noticed the massive majority of models produced within the 15 years from 1976 to 1991, with a pointy contraction in manufacturing after the Soviet collapse in addition to a contraction within the variety of operational models. 

The discrepancy in numbers produced displays each the F-16’s a lot wider use within the U.S. Air Power, in addition to its a lot larger recognition on export markets. The F-15 had solely six export shoppers whereas the F-16 had 25 — with Italy additionally having leased the plane for a short interval. The F-16 is just not solely less expensive each to buy and to function, however can be extensively seen was more economical with trendy variants compensating for his or her radar’s small measurement with sophistication and for a brief vary with the mixing of conformal gasoline tanks. When it comes to fight efficiency the F-15 is way superior, notably in air to air engagements, however that is solely assuming that equal variants are being in contrast. The weakest F-15s, the Israeli F-15A/B jets from the Seventies, could be very overwhelmingly outmatched by trendy F-16 variants such because the F-16 Block 70 and F-16V bought to Taiwan, the F-16E within the United Arab Emirates, or Japan’s spinoff the F-2. Even F-16s from the Nineteen Nineties would doubtless submit a severe problem for such outdated Eagles to sort out. The F-15 has had one very important benefit which ensures that it receives extra overseas curiosity as we speak that the F-16, which is that it has no successor in manufacturing as a result of very early termination of the F-22 Raptor program that was meant to succeed it. The F-16, against this, has seen its successor the F-35A not solely extensively produced but additionally marketed extensively for export which successfully strips it of any market share from increased finish shoppers. 

It’s notable that whereas the U.S. Air Power and NATO member states extra usually have relied on the F-16, and different fighters from comparable weight ranges such because the Rafale and Eurofighter, to kind the majority of their models, Russia moved in the wrong way after the top of the Chilly Battle with nearly all fighters and interceptors in service as we speak being heavyweights – and people few that aren’t being medium weight MiG-29s largely inherited from the Soviet period. This implies Russian fighters will on common be for much longer ranged, have over double the thrust and deploy a lot bigger sensors and considerably extra ordinance than their Western counterparts, which partly compensates for a way overwhelmingly outnumbered the Russian Air Power could be in a battle with the alliance. China has adopted the identical pattern, albeit much less radically, buying its first heavyweight fighters in 1991 and comprising a rising portion of its fleet from them primarily superior Flanker derivatives such because the J-16 in addition to the new fifth technology J-20

The U.S. Air Power partly compensates by modernising its F-16s, with the newest F-16V variants being greater than a match for a few of Russia’s older heavyweights such because the Su-27SM regardless of being a lot smaller. It additionally deploys elite models of F-15s and F-22s which, a lot as was the case within the Gulf Battle, are anticipated to be employed to sort out increased efficiency enemy fighters. F-16s will in the meantime have interaction older plane or tackle a larger burden in air to floor operations. The F-15 is anticipated to stay in service considerably longer than the F-16 largely as a result of F-22’s failure to interchange it, with the U.S. Air Power having over 100 on order that are but to be delivered after resuming orders in 2018, and also will outlive the F-22 with the comparatively small numbers produced set to be retired many years early. The F-16, in the meantime, will nonetheless play a central position within the U.S. Air Power properly into the 2030s, with the F-35 not anticipated to be prepared for even medium depth fight for a few years to return and presently restricted to a really restricted preliminary working functionality with over 800 efficiency points – ensuing within the Pentagon persevering with to delay authorising it for full scale manufacturing.
