WHY ISRAEL WANTS THE F-15 SE “SILENT EAGLE” AND WHAT IT MEANS FOR THE US AIR FORCE
According to news reports, Israel wants the F-15 Silent Eagle. The F-15 Silent Eagle is a stealthy evolution of the F-15 Strike Eagle, which forms the backbone of Israel’s Air Force.
Some analysts are surprised Israel would request the Silent Eagle. But there are good reasons for it: in fact, the reasons are so good that if our Air Force had common sense it would reduce the size of the F-35 Joint Strike Fighter buy and get the Silent Eagles for our Air Force too.
There is, of course, both a sort of respect and competition that characterizes relations between the US Air Force and Israel’s Air Force. And there are differences in mission: Israel is a regional power, not a superpower. It mostly fights in its own neighborhood; although the Iranian challenge means Israel needs more long range aircraft that can carry a significant load of air to ground weapons. The F-35 is not that airplane.
The F-35 is one of the most controversial and expensive aircraft ever built, rivaled only by the even more costly but canceled F-22. But the F-22’s are aging and soon need to be upgraded; the F-35’s are stumbling forward, but the program has stimulated massive criticism from aviation experts who fault its value as a front line fighter.
The F-35 program hinges on two highly debatable suppositions.
Betting the Farm
The first supposition is that the F-35 can be the main fighter aircraft in the US inventory even though its capability to perform multirole tasks is far from certain. The US Air Force has bet the farm on the F-35; in the end it means a smaller air force and one with far less flexibility than the air force now has.
Beyond Visual Range (BVR)
The second supposition is that it’s beyond visual range capability is the essential trump card that makes the F-35 superior to the competition. BVR capability is important, but BVR is not a technology solely under US control –our main competitor, Russia, has BVR and is getting better and better at enhancing all its onboard electronic capabilities.

The idea behind BVR was born out of the famous air battle in June 1982 over the Bekaa Valley, where Israel, using mainly US aircraft (plus its home-grown Kfir) decimated the Syrian Air Force. The reason for the success was that the US F-15’s that were used in that battle had look-down shoot-down radars, a technology the Russians would not have for another ten years. This meant that high-flying Israeli fighters could pick out Syrian MiGs and Sukhoi’s and hit them before they saw the Israeli planes.
But, while look-down shoot-down was really important, it is only a part of the story. The Israelis also had command and control and radar planes in the area giving them excellent coverage -they saw the Syrian planes from the moment they lifted off from their bases. And, even more importantly, Israel using brilliant home-grown tactics, were able to shut down and destroy most of Syria’s ground-based air defense missile systems. The elimination of Syria’s SAMs (surface to air missiles) meant that the Syrian Air Force was left on its own. Consequently, 86 Syrian fighter planes, including the Mach-3 MiG 25, were shot down. Israel lost no planes in air to air combat; it had four combat losses to ground fire.
Thus, the translation of what happened in 1982 to 2015 is not so simple. In 1982, the US had superior technology. In 2015, the US has excellent technology, but potential adversaries are gaining ground. Russia, for example, now has stealth in its forthcoming PAK FA-T50 (made by Sukhoi, an important evolution of the Su-35 4th++ generation fighter). It has Active Electronic Scanned Array radar (just like the F-35 and F-15 SE); it has infrared tracking capability; it has BVR weapons; and most of the other features of the F-35. But, unlike the F-35, the Su-35 and T-50 are excellent maneuverable fighter planes. For whatever reason, once the F-35 exhausts its air defense missiles, it is a sitting duck unless it can run away in a hurry. Here the Su-35 and T-50 are exceptional because they have supercruise capability that the F-35 lacks. Supercruise is the ability to operate supersonically without using engine afterburners. This means far greater range (because afterburners are fuel hogs), and it means weapons launched under supercruise have greater range too. Can the F-35 escape against a supercruising F-35 or T-50? Most experts think the F-35 cannot.
This brings us back to the reasons why the Israelis are seeking the F-15SE. They need a fighter-bomber that can fight. They understand that if the Russian relationship with Iran continues, that the Iranians will want top of the line aircraft and will pressure the Russians to give them. Iran is already getting the best air defense missiles the Russians have (violating current arms agreements set by the United Nations). It won’t be long before the Russians agree to sell modern fighters to Iran, and Israel must plan on that relatively near-term eventuality.
For Israel, there are other considerable gains in buying the F-15SE. It is an evolution of an aircraft already in inventory, which means all the logistics and support systems are already in place. Pilots are already well trained on the platform and have experience in combat, meaning that the capabilities of the plane are well known. And the F-15SE costs less than half of what the F-35 costs, meaning that Israel can get much more punch for the buck than the F-35 offers. Indeed, the F-35’s main contribution to air forces around the world is that it is so unaffordable it will shrink every air force that buys it. This must cause delight in Moscow as well as Beijing.
But even more concerning is why the US Air Force isn’t mitigating the risk of the F-35 by buying an equal number of F-15 Silent Eagles? It does not take a supercomputer or even an abacus to understand that putting the entire US Air Force at risk with only one fighter plane in the inventory is a danger to national security. If the platform fails to perform, America will not only risk its credibility, but our allies who are buying the F-35 are going to be left in the lurch.
Indeed, there are even more risks. The US cannot afford to keep its older planes flying once the F-35’s enter the inventory. The F-15’s and F-16’s are unlikely to be further modernized or even properly maintained.
Even worse, the soaring cost of the F-35 and the difficulty of maintaining it in any power projection scenario (and the huge support costs) means that even fewer will be purchased and even less will be available in the field when needed. This is not a scenario that should be welcomed, and it is likely the Israelis understand the problem all too well. The F-35 was pushed at them; they did not jump up and down wanting it. Now, for all practical purposes, they really want to hedge their bets or get out from under the f-35 albatross.
So what should we expect? Any suggestion the US Air Force should buy the Silent Eagle will be met by extreme hostility for sure. In fact, it is likely the Pentagon will try and block Israel’s request, or try and unload some more F-35’s to shut the Israelis up. That’s the reality of power-Pentagon politics these days. What the Silent Eagle needs is some Congressional champions to head off the usual bone-headed Pentagon argument to spend more, get less, and risk our security.
