The Israel Air Force’s F-15 fleet is undergoing an upgrade, with systems that  make it better equipped for complex long distance attack scenarios. The systems  are being installed in both the F-15 and the F-15I -- a model of the F-15 that  was developed by its U.S. manufacturer specifically for the  IAF.
According to IDF journal BaMachaneh, the F-15I model is currently  being fitted with two new systems – one called “Barad Pelada” (“Steel Hail”),  and another named Lightning. 
The Barad Pelada advanced weapons system  has been operational in the IAF’s F-16s for almost four years, but had to be  modified in order to fit the F-15. 
Barad Pelada is an advanced Israeli  armament that operates like a smart bomb. “The system is unique in that it is  able to plan the bombing in an accurate way by identifying the target from  above,” a knowledgeable source in the IAF explained. “After the identification,  the system carries out guidance to the target and only then is impact  made.”
The Lightning advanced attack system has also been in use in the  IAF’s other jets. Until now, the F-15I jets had to rely on the older Inbar  system, which used to be fitted in all of the IAF’s jets but was gradually  phased out. 
The Inbar system is capable of providing an operational  solution in some ranges, but other attack scenarios require advanced systems  like the Lightning, IAF sources said. “The need for the new system led to an  accelerated procedure of development of advanced means,” a source in the IAF’s  Weapons Department explained. “Once the testing at the Flight Experiment Center  is finished, we will complete the system’s integration in the  aircraft.” 
For the time being, however, the F-15I jets will not part  with the older Inbar systems. “From now on, the aircraft will enjoy a  combination of both attack systems and will enjoy a meaningful advantage in  their operational activity,” the sources said.
The F-15 jets, meanwhile,  recently received a new weapon system named “Barad Kaved” (“Heavy Hail”) and  used it for the first time during operation “Cast Lead” in Gaza in early 2009.  IAF sources said the use was a success. The F-15 fighters used Barad Kaved in  attacks with zero malfunctions, and “we are very pleased with its performance in  the operation,” the sources said.
“The reelection of Iran’s president,  his grave utterances regarding his will to harm the state of Israel and Iran’s  continual effort to achieve unconventional weapons require us to maintain an  army that is coiled and ready to spring into action, and an Air Force that is  skilled and sharp as a razor, that will stand up to any enemy and remove any  threat from our citizens and residents,“ IDF Chief of Staff Lt.-Gen. Gabi  Ashkenazi said Thursday in an IAF ceremony for new pilots at the Hatzerim Air  Force Base.
