Who Wins?
F15 ♔
When the Boeing F-15A first flew in July 1972, the Eagle was the ultimate air superiority fighter. Fast, high-flying, agile and built around a massive APG-63 pulse-doppler radar, the Soviet Union had nothing that could match it. Overtime, McDonnell Douglas—the F-15’s original manufacturer before its merger with Boeing—adapted the airframe into a potent multirole fighter that eventually became the F-15E Strike Eagle. While both the air superiority oriented F-15C and the strike-oriented F-15E will remain in service with the U.S. Air Force for decades to come, by far the most advanced current version of the Eagle has been ordered by Saudi Arabia. But will that be enough compete with Lockheed Martin’s F-35 Joint Strike Fighter?
Saudi Arabia has ordered some 84 new-build F-15SAs and 70 upgrade kits to retrofit their existing Strike Eagles to the new standard. When the massive $29.5 billion contract was signed December 2011, it was the largest foreign military sale in the history of the United States. In the ensuing years, Boeing has developed and tested the upgraded jets, which are powered by General Electric F110 engines rather than Pratt & Whitney F100s. The company is finally starting to get ready to deliver the aircraft. The first of the new jets rolled out of the Boeing plant in Saint Louis, Mo., earlier this earlier in April.
Perhaps the single most significant upgrade found in the F-15SA package is a fly-by-wire flight control system—previous versions of the Eagle used a hybrid computer augmented stability system. The addition of the fly-by-wire system allowed Boeing to reactivate the F-15’s two dormant outboard wing hardpoints that had always been present, but never used. The problem previously had been stability differences induced by carrying weapons on stations one and nine.
Additionally, the F-15SA is equipped with the advanced APG-63 v.3 active electronically scanned array (AESA)—though, potentially, future customers might order the more capable APG-82 that is being retrofitted to U.S. Air Force’s own Strike Eagles. The F-15SA is also equipped with BAE’s advanced Digital Electronic Warfare System (DEWS), which has digital radio-frequency memory jamming capability.
The new digital system looks across an entire frequency band continuously rather than scanning through a frequency band—which means that even low probability of intercept (LPI) signals might be detected (radars on stealth fighters like the F-22 and F-35 use LPI techniques to try mask their emissions for electronic support measures suites). Further, its interferometric antennas can generate far more accurate bearing measurements than the current system.
The DEWS’ performance is probably comparable to the F-22’s or F-35’s electronic support measures suites since it is based on those systems. It’s head and shoulders better than anything currently fielded by the U.S. Air Force’s own Strike Eagles. U.S. Air Force jets won’t have anything comparable until the Eagle Passive/Active Warning and Survivability System (EPAWSS) is fielded.
The F-15SA is also equipped with Lockheed Martin’s AN/AAS-42 infrared search and track system. And all of that information from the radar, infrared search and track and the electronic warfare system are fused together—similar to the F-22 and F-35—into a coherent picture. That picture is displayed on large-format color displays that are similar to those found on the F-35—in both the front and rear cockpits. Both aviators are equipped with the Joint Helmet Mounted Cueing System. Taken together, the F-15SA is an extremely formidable multirole fighter—possibly the single best fourth generation fighter the United States has ever produced.
But is that enough to compete with the F-35 on the open market place? Longer-term, it looks like the F-35 will be the dominant player on with fighter market—at least in parts of the world aligned with the West. Stealth is a major selling point with the inevitable proliferation of advanced Russian and Chinese-built surface-to-air missile systems. Further, the F-35 has the backing of the United States government—which is a huge trump card for the program. In the short-term, Boeing may have opportunities to sell the F-15 to wealthy customers who need a very capable long-range jet and who can afford the Eagle’s hefty price tag. Those customers are likely to be in the Middle East or Asia—nations that are not likely to be cleared to receive the F-35 in the near term.
But one also has to remember that buying a fighter is less about aircraft performance or even military requirements than pure simple geopolitics. Buying a jet means you as a military are tying yourself into a strategic alliance with another country and its hardware. For many nations, making sure they are able to tie seamlessly into the Pentagon’s forces is of paramount importance. So even if you buy American, unless it’s a variant operated by the U.S. military, you might end up with an expensive boutique fleet with a lot of expensive maintenance bills.
