Porcupine Dart is the name of a new Israeli armor defense system that, in a test at the Aberdeen Proving Grounds in Maryland, successfully hit an incoming tank round and destroyed it. This is apparently the first time that a tank round was intercepted and destroyed in mid-flight.
Another new Israeli tank defense system, the radar-based Windbreaker, fires small metal slugs at an incoming projectile, detonating its warhead a distance from the vehicle. It has already been used successfully against rocket-propelled grenades fired against tanks patrolling the Gaza border. (Thanks to Daily Alert.)
Israel will need all the new defense technology it can develop, probably sooner rather than later. Especially as Fatah has now, under Egypt's leadership, agreed to form a Palestinian national unity government with Hamas. Hamas continues to demand the destruction of Israel and large numbers of Egyptians want to tear up the peace treaty with Israel, so I absolutely cannot understand why anyone thinks the Hamas-Fatah accord will promote peace.
