Operation Density (or "Operation Specific Weight", Hebrew: מבצע משקל סגולי), also known as "The Fajr Night", was a Military operation conducted by the Israeli Air Force on the second day of the 2006 Lebanon War. In the operation, official Israeli military sources claim that the majority of Hezbollah’s long-range rockets were destroyed in air strikes that lasted 34 minutes. Other sources question whether the attack had any apparent effect on Hezbollah's capabilities.
