context_page_description: A Lazy Dog is a small, unguided kinetic projectile typically about 1.75 inches in length, 0.5 inches in diameter, and weighing about 0.7 ounces.
  The weapons were designed to be dropped from an aircraft. They contained no explosive charge but as they fell they would develop significant kinetic energy making them lethal and able to easily penetrate soft cover such as jungle canopy, several inches of sand, or light armor. Lazy Dog munitions were simple and cheap; they could be dropped in huge numbers in a single pass. Though their effects were often no less gruesome or indiscriminate than other projectiles, they did not leave unexploded ordnance that could be active years after a conflict ended.
  Lazy Dog projectiles were used primarily during the Korean and the Vietnam Wars.
context_section_description: The Shape 2 projectile was sent to the Far East Air Force for combat use by mid-1952. FEAF immediately ordered 16,000 Lazy Dog weapon systems. An Air Force Lieutenant Colonel named Haile attached to the Armament Laboratory spent 90 days in Japan to set up local manufacture of the Lazy Dog weapons and train crew members in their use. Project Lazy Dog continued throughout 1952 to determine the optimum characteristics for stable dispersion containers and the feasibility of substituting a Lazy Dog warhead for the explosive nose of the Matador missile. The Lazy Dog program was still ongoing in the late 1950s.
  Lazy Dog projectiles could be dropped from almost any kind of flying vehicle. They could be hurled from buckets, dropped by hand, thrown in their small shipping bags made of paper, or placed in a Mark 44 cluster adaptor—a simple hinged casing with bins built in to hold the projectiles, opened by a mechanical time delay fuze. The adaptors themselves were 69.9 inches long and 14.18 inches in diameter. They would be shipped empty, then filled by hand. Depending on how many projectiles could be packed in, loaded weight varied between 560 and 625 pounds, with the theoretical maximum number of projectiles listed as 17,500.
  Regardless of  how they were released into the air, each "Lazy Dog" projectile would develop an enormous amount of kinetic energy as it fell, penetrating nearly any material upon hitting the ground. Some reports say that their speeds often exceeded 700 feet per second (480 mph; 210 m/s) before impact.
  A variant version of the "Lazy  Dog" projectile was developed for the recoilless rifle. However, development was suspended because another kind of flechette solution was used for the recoilless rifle instead.
