" In 1998, when the Clinton administration launched 75
Tomahawk cruise missiles at Osama bin Laden’s bases in response to al Qaeda’s bombing of U.S. embassies in Kenya and Tanzania, six of the missiles misfired and landed across the border in Pakistan. It has long been suspected that these unexploded missiles were studied by Pakistani and Chinese scientists. Ted Postol, a professor of science, technology, and international security at MIT, confirms this: “A Pakistani colleague of mine told me that a significant number of those missiles that we launched at Afghanistan actually landed in Pakistan and those guys reverse-engineered them.”
The propulsion system of the
Babur missile that Pakistan tested in 2005 definitely resembles that of the BGM-109 Tomahawk. After an initial launch by a solid-fuel booster, a cruise turbo fan engine cuts in, giving the Babur a speed of 880 kilometers per hour and a range of 500 kilometers. "
