This week, Boeing Integrated Defense Systems (IDS) unveiled the F-15 Silent Eagle (F-15SE) at its headquarters in St. Louis, Missouri. A business unit of the Boeing Company, Boeing IDS showcased the latest configuration of the F-15 Eagle, an all-weather tactical fighter that McDonnell Douglas first developed in the 1970s.
The F-15SE isn't designed for the United States Air Force (USAF), however - or for any branch of the U.S. military for that matter. According to Mark Bass, Boeing's F-15 Program Vice President, the F-15 Silent Eagle is "designed to meet our international customers' anticipated need for cost-effective stealth technologies."
What is Stealth?
Stealth technologies are designed to make military aircraft less visible (or even invisible) to radar, infrared (IR), sonar, and other detection methods. Radar-cross section (RCS) reduction requires changes to an aircraft's shape; the use of a non-metallic airframe, radar absorbing materials (RAM), and special stealth coatings; and even radar countermeasures. Stealth technologies also involve minimizing the airplane's acoustic profile, visibility, IR signature, and radio frequency (RF) emissions.
Boeing's Silent Eagle
Like other stealth aircraft, the F-15SE uses stealth coatings and slightly-angled surfaces to reduce radar reflections and thermal loads. The Silent Eagle also has canted vertical tails and redesigned conformal fuel tanks (CFT) that allow weapons to be carried inside. In addition to reducing the plane's radar cross-section, the F-15SE's canted tails provide lift, reduce airframe weight, and improve aerodynamic efficiency. The internal weapons carriage reduces the plane's visibility while improving fuel efficiency and aircraft range.
Lockheed-Martin's JSF
According to Defense Update, the Boeing F-15SE may deal the Joint Strike Fighter (JSF) "another, yet unexpected blow". Designed by Lockheed-Martin, the JSF multi-role jet fighter is optimized for air-to-ground missions, but is supposed to meet the needs of three branches of the U.S. military (Air Force, Navy, and Marines) as well as America's allies. The U.S. Department of Defense (DoD) plans to buy 2400 of these stealthy supersonic aircraft, but international sales could account for another 2000 to 3500 planes.
Air-to-Air Combat?
So could Boeing's F-15SE really give Lockheed's JSF a run for its money? According to a recent report from the Government Accountability Office (GAO), the JSF is $38 billion over budget mid-way through its development cycle. Meanwhile, the Boeing F-15SE is being marketed only to international customers - and not to the U.S. military.
Should it be?
