The region was used for live fire exercises in 1943 during World War II when Camp Tarawa temporarily held troops on Parker Ranch . About 91,000 acres (37,000 ha) were leased from Richard Smart , owner of the ranch. At that time it

The Jeep was equipped with an attached launcher for the M28 or the M29, as required, whereas the Davy Crockett carried by an armored personnel carrier
276-416: A 'safe' setting, and so acted as a second safety switch. The complete round was 31 inches (79 cm) long, with a diameter of 11 inches (28 cm) at its widest point; a subcaliber piston at the back of the shell was inserted into the launcher's barrel for firing. The M388 atomic projectile was mounted on the barrel-inserted spigot via bayonet slots. Once the propellant was discharged, the spigot became
368-523: A ballistic match to it. It contained 16 pounds (7.3 kg) of Composition B high explosive that was detonated by an electrical switch on impact with the ground. The practice round had a significant destructive effect in its own right and was intended to be used in combat in an emergency situation. A further type of dummy training round, the M421, was completely inert and not intended to be fired. The M388 could be launched from either of two launchers known as
460-456: A five-man crew, the squad consisting of a Commander, Gunner, Assistant Gunner, Loader and Computer. The commander of the M388 could issue use and have the weapon fired in a matter of minutes. The weapon was made from lightweight metals – the tripod was aluminum, the barrel was titanium – and it was possible to break the smaller M28 weapon into three loads that could be carried by the crew, with

President George Washington went to Congress to remind them of their duty to establish a military twice during this time. Finally, on the last day of the session, September 29, 1789, Congress created the War Department . The War Department handled naval affairs until Congress created
644-654: A mix of M28 and M29 launchers (e.g., one of each per D/C section). Eventually, the M28s were replaced by M29s, so that both the armored personnel carriers and the Jeeps carried the M29. Both recoilless guns proved to have good accuracy in testing, most training shots landing within ten feet (3.0 m) of the point of aim, and CEP under 160 feet (50 m), with a 100% instant casualty radius in excess of 520 feet (160 m). The shell's greatest effect would have been its extreme prompt neutron radiation which would have killed most of
736-410: A similar trajectory to the nuclear projectiles and produced white smoke when they landed, helping determine range. The Davy Crockett was fired remotely. A mechanically-operated detonator at the end of 72 feet (22 m) of detonating cord led to the propellant charge. The M388 nuclear projectile was attached to a titanium piston by means of a bayonet mount . When fired, the piston was blown out of
828-535: A single Davy Crockett could replace 40–50 salvos of a whole divisional artillery park – allowing the funds and troops normally needed for this artillery to be invested into further troops, or not having to be spent at all. US NATO commanders strongly opposed Strauss's ideas, as they would have made the use of tactical nuclear weapons almost mandatory in case of war, further reducing the ability of NATO to defend itself without resorting to atomic weapons. The Davy Crockett Weapon System's use of depleted uranium in
920-580: A standard for the crew to follow when firing the M388; they advised that the soldiers shelter their bodies behind a sloped hill and lie in prone position on the ground with their necks and heads covered. The warhead was tested on July 7, 1962, in the Little Feller II weapons effects test shot, and again in an actual firing of the Davy Crockett from a distance of 1.7 miles (2.7 km) in the Little Feller I test shot on July 17, 1962. This
1012-450: A traditional artillery round. This meant that it had to be fired out of a short range recoilless rifle. Both weapons fired the same projectile, propelled using a separate cartridge. The smaller M28 used a 11 lb (5 kg) explosive cartridge to launch the warhead. The larger M29 used either a 11 lb or a 19 lb (8.5 kg) propellant charge, depending on the desired range. The launcher systems were muzzle loading weapons;

Heavy equipment is either flown into Hilo, or else shipped via barge to Kawaihae Harbor, about 40 miles (64 km) away on the Saddle Road. Because of this remoteness, the area is used mostly for short training sessions. The barracks for about 2,000 troops were constructed in April 1955 from prefabricated buildings used in World War II. The support area includes 600 acres (240 ha) of logistic and administrative facilities.

Several archaeological sites have been found in the training area, including the Bobcat Trail Habitation Cave , listed in the National Register of Historic Places . To reduce fire danger and damage from feral goats, areas were fenced. Weapons such as the Davy Crockett nuclear rifle with dummy warheads and depleted Uranium have been used at PTA. After initial denials, an investigation concluded that spotting rounds were used in
7544-424: The spotting round led to concerns about troop exposure to the material. However, studies indicated that there was no risk of exposure to the material during use of the weapon. As a nuclear munition, however, an exceptionally strong safety program was required. This included providing render-safe procedure documentation to explosive ordnance personnel before delivery of the first warheads. Program documentation for
