Hamas possesses Iranian-made Fajr-5 rockets, which have a range of roughly 75 kilometers. Recently, Hamas has claimed that rockets launched at Jerusalem on Nov. 16 were locally made rockets that various Hamas representatives were calling M-75s, Grad 75s or Grad 76s. Similar Timing for Long-Range Rockets from Gaza Stratfor If Hamas has indeed developed the capability to independently develop long-range rockets, then the dynamic of this conflict shifts dramatically. It would be one thing for Israel Defense Forces to eliminate a finite number of rockets that have been successfully smuggled into Gaza. The rockets themselves are massive — roughly 6 meters (approximately 20 feet) long and some 900 kilograms (roughly 2,000 pounds) in weight — and are thus highly vulnerable to detection once deployed.
