"Israel has developed observation balloons equipped with sophisticated cameras and surveillance systems used to thwart terror attacks from Gaza.[67]
"The IDF also has several large internal research and development departments, and it purchases many technologies produced by the Israeli security industries including IAI, IMI, Elbit Systems, Rafael, and dozens of smaller firms.

"In response to the price overruns on the US Littoral Combat Ship program, Israel is considering producing their own warships, which would take a decade[68] and depend on diverting US financing to the project."
