F15I hunh? What's the I stand for, I wonder...
The Israeli Air Force (IAF) chose to acquire the latest version of the world renowned Lockheed Martin F-16 over additional purchases of the more expensive twin engine Boeing F-15I - for which the IAF placed an order for 25 in 1997. The estimated $4.5 billion dollar F-16I deal ($45 million per aircraft) will be financed by the annual U.S. military aid package and concludes the largest Israeli military purchase in history. Each F-15 cost approximately $84 million.
The F-16I is a heavily modified two seat version of the U.S. Air Force's F-16D Block 50/52-series fighter. In addition to the new and more powerful Pratt & Whitney F100-PW-229 engine, the F-16I boasts numerous internal and external advancements and modifications. For example, the Sufa has been customized with new avionic technologies, internally mounted FLIR (forward looking infrared) viewers, and cutting edge weapon system hardware provided by the Israeli defense company Lahav - a division of Israel Aircraft Industries.
