from THE JERUSALEM POST:
The Israel Air Force used a new bunker-buster missile that it received recently from the United States in strikes against Hamas targets in the Gaza Strip on Saturday, The Jerusalem Post learned on Sunday.
The missile, called GBU-39, was developed in recent years by the US as a small-diameter bomb for low-cost, high-precision and low collateral damage strikes.
Israel received approval from Congress to purchase 1,000 units in September and defense officials said on Sunday that the first shipment had arrived earlier this month and was used successfully in penetrating underground Kassam launchers in the Gaza Strip during the heavy aerial bombardment of Hamas infrastructure on Saturday. It was also used in Sunday's bombing of tunnels in Rafah.
The GPS-guided GBU-39 is said to be one of the most accurate bombs in the world. The 113-kg. bomb has the same penetration capabilities as a normal 900-kg. bomb, although it has only 22.7 kg. of explosives. At just 1.75 meters long, its small size increases the number of bombs an aircraft can carry and the number of targets it can attack in a sortie.
Tests conducted in the US have proven that the bomb is capable of penetrating at least 90 cm. of steel-reinforced concrete. The GBU-39 can be used in adverse weather conditions and has a standoff range of more than 110 km. due to pop-out wings.
