During the 2006 Lebanon War, the vessel was patrolling in Lebanese waters ten nautical miles off the coast of Beirut. It was damaged on 14 July 2006 on the waterline, under the aft superstructure by a missile fired by Hezbollah that reportedly set the flight deck on fire and crippled the propulsion systems inside the hull. However, INS Hanit stayed afloat, withdrew and made the rest of the journey back to Ashdod port for repairs under its own power. Four crew members were killed during the attack: Staff Sergeant Tal Amgar, Corporal Shai Atas, Sergeant Yaniv Hershkovitz, and First Sergeant Dov Steinshuss. According to the Israeli Navy, the ship's sophisticated automatic missile defense system was not deployed, even though the early warning system is usually deployed during peace-time wargames. In the aftermath of the event, reports suggested that no known intelligence existed which would have pointed to the fact that such a sophisticated missile was deployed in Lebanon by Hezbollah. In fact, the investigative work of Ha'aretz journalists Amos Harel and Avi Issacharoff showed that an intelligence officer identified only as Colonel K. had given a lecture on 21 April 2003, predicting that Hezbollah possessed shore-to-sea missiles. Furthermore, on the morning of 14 July 2006 a branch head of naval intelligence described as Lieutenant-Colonel Y. briefed the head of naval intelligence, Colonel Ram Rothberg, telling him that "ships enforcing Israel's naval blockade on Hezbollah should take into account the possibility of a C-802 missile being fired on them." No warning was issued based on this assessment, however; if it had, Israeli ships would have moved further away from the shore and activated their anti-missile systems. As a result of the incident, two navy officers, two junior officers and the commander of the ship were formally reprimanded and repositioned to non-commanding positions on land. One of the junior officers had shut down the central radar and parts of the defence system without notifying the commander, in the belief that the ship was not under threat.
IDF report
An official IDF report on the Lebanon war incident reveals that the crew did not act sufficiently in order to anticipate the threat. The IDF report, which was submitted to Chief of StaffDan Halutz, said, "as far as the intelligence picture is concerned, it was found that despite the lack of pinpoint information about the weapon in the hands of Hezbollah, there was information in the Navy in the past that could have led to some type of an assessment that the enemy holds shore-to-ship missiles." In addition, failures were uncovered in "the way the forces understood the operative reality and implemented it." As there were no perceived missile threats, an officer had left the ship's anti-missile suite disabled, in energy-saving standby-mode, while patrolling near the coast. The Israeli military alleged that Iranian military advisors from the Islamic Revolutionary Guard Corps had assisted with deploying and readying the missile launcher.
Subsequent service
Repairs took months; the ship returned to active service in 2007. INS Hanit served as Ram Rothberg's command ship during the 2014 Operation Full Disclosure.
