This is at 20 degrees Celsius, so it's a nice comfortable temperature at sea level, which is roughly about 760 miles per hour. Now if the temperature were to drop, so if temperature goes down, so does the speed of sound. And likewise, if the temperature goes up, the speed of sound goes up.
One single company won more than three-quarters of these funds, however, in a single contract win: Hellfire Systems. Hellfire, as we've discussed in the past, is the wholly owned Lockheed Martin (NYSE:LMT) subsidiary that manufactures Hellfire air-to-ground missiles for the military.
The AGM-114 Hellfire is an air-to-surface missile (ASM) first developed for anti-armor use, but later models were developed for precision strikes against other target types, such as, in the case of a Predator drone, targeted killings, usually by the United States or other western nations.he AGM-114L, or Longbow Hellfire, is a fire-and-forget weapon: equipped with a millimeter wave (MMW) radar seeker, it requires no further guidance after launchâeven being able to lock-on to its target after launch âand can hit its target without the launcher or other friendly unit being in line of sight of the target.
