After the booster burns out, the payload section continues on a ballistic trajectory to the target. A variation on the airborne rocket was the addition of rocket motors and fins to conventional bombs. This had the effect of flattening the trajectory, extending the range, and increasing velocity at impact, useful against concrete bunkers and hardened targets. These weapons were called glide bombs, and the Japanese had 100-kilogram and 370-kilogram (225-pound and 815-pound) versions.

According to the Federation of American Scientists, a ballistic missile is one that has a ballistic trajectory over most of its flight path. What that means is that once the missile burns up the fuel that propels it, the missile keeps moving, the same way that a bullet does after it's been fired out of a gun. It follows a path determined by the speed of its launch and the force of gravity trying to pull it back toward the Earth's surface.
Efficiency in modern warfare
He covers uncrewed robotics and other drones, communications systems, the nuclear enterprise, and the technologies that go into planning, waging, and mitigating war. World War II saw the expenditure of immense resources and talent for the development of rocket-propelled weapons. Even the new rockets, however, could not compete with the greatly improved artillery with rifled bores. The rocket corps of most European armies were dissolved, though rockets were still used in swampy or mountainous areas that were difficult for the much heavier mortars and guns. The Austrian Rocket Corps, using Hale rockets, won a number of engagements in mountainous terrain in Hungary and Italy.
Ballistic Missiles
Designed chiefly for use against tanks and fortified positions at short ranges (up to 600 yards), the bazooka surprised the Germans when it was first used in the North African landings of 1942. Although the rocket traveled slowly, it carried a potent shaped-charge warhead that gave infantrymen the striking power of light artillery. In the United States, meanwhile, Robert Hutchings Goddard was conducting theoretical and experimental research on rocket motors at Worcester, Mass. Using a steel motor with a tapered nozzle, he achieved greatly improved thrust and efficiency. During World War I Goddard developed a number of designs of small military rockets to be launched from a lightweight hand launcher. By switching from black powder to double-base powder (40 percent nitroglycerin, 60 percent nitrocellulose), a far more potent propulsion charge was obtained.

These weapons are powered only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles (SRBM) typically stay within the Earth's atmosphere, while most larger missiles are exo-atmospheric. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight and thus restricted to the atmosphere.
Antiaircraft rockets
Earlier versions of these missiles used inertial navigation; later versions use much more accurate TERCOM and DSMAC systems. Many researchers besides Goddard used the wartime interest in rockets to push experimentation, the most noteworthy being Elmer Sperry and his son, Lawrence, in the United States. The Sperrys worked on a concept of an “aerial torpedo,” a pilotless airplane, carrying an explosive charge, that would utilize gyroscopic, automatic control to fly to a preselected target. Army Signal Corps organized a separate program under Charles F. Kettering in Dayton, Ohio, late in 1918.
Army when the Armistice was signed; they became the forerunners of the bazooka of World War II. Rocket and missile system, any of a variety of weapons systems that deliver explosive warheads to their targets by means of rocket propulsion. Ballistic missiles on the other hand are not powered during most of their flight. During the launch they are given a high initial velocity and then coast throughout most of their flight. Ballistic missiles are guided during brief periods of their flight, aerodynamically and/or by thrust vectoring. Intercontinental Ballistic missiles go into a suborbital paths and spend a considerable part of their trajectory outside the atmosphere.
Cruise Missiles vs Ballistic Missiles
These were fired from a variety of towed and vehicle-mounted multitube launchers, from launching rails on the sides of armoured personnel carriers, and, for massive bombardments, even from their packing crates. Mobile German rocket batteries were able to lay down heavy and unexpected concentrations of fire on Allied positions. The 150-millimetre Nebelwerfer, a towed, six-tube launcher, was particularly respected by U.S. and British troops, to whom it was known as the “Screaming Meemie” or “Moaning Minnie” for the eerie sound made by the incoming rockets.
Hypersonic
During this phase, which can last for less than a minute, strategic warheads can be traveling at speeds greater than 3,200 kilometers per hour (1,988 miles per hour). A five-inch rocket with an explosive warhead was developed in Great Britain. These rockets, fired from specially equipped naval vessels, were used in heavy coastal bombardment prior to landings in the Mediterranean. Throw-weight is normally calculated using an optimal ballistic trajectory from one point on the surface of the Earth to another. These missiles travel faster than the speed of sound, usually using ramjet engines. Recently North Korea continued its weapons testing, firing cruise missiles amidst escalating tensions and “war preparations” against South Korea.
Other successful uses were by the Dutch colonial services in Celebes and by Russia in a number of engagements in the Turkistan War. Maximum ranges of Congreve rockets were from one-half mile to two miles (0.8 to 3.2 kilometres), depending upon size. They were competitive in performance and cost with the ponderous 10-inch mortar and were vastly more mobile. The USAF adopted the AGM-86 for its bomber fleet while AGM-109 was adapted to launch from trucks and ships and adopted by the USAF and Navy.
When the predetermined number of revolutions had occurred, the wings of the airplane were dropped off and the aircraft carrying the bomb load dropped on the target. Unlike ballistic missiles, which arc up into space before traveling back down towards earth, cruise missiles fly close to the ground, making it hard for radar on the ground that’s pointed up at space to see them. Throw-weight is a measure of the effective weight of ballistic missile payloads. It was once also a consideration in the design of naval ships and the number and size of their guns. Ballistic missiles vary in size and capability from battlefield types such as the ATACMS missile fired from the M270 MRLS, to regional range types such as the MGM-31 Pershing missile to intercontinental range types such as the Minuteman III. Warhead types can range from conventional aerial explosives like Tritonol 80/20 to chemical, nuclear or thermonuclear types.
The missiles were guided by an inertial navigation system that was updated during flight by a technique called Tercom (terrain contour matching), using contour maps stored in the system’s computerized memory. The air-launched cruise missile (ALCM) had a length of 6.3 m (20.7 feet); it attained a range of 2,500 km (1,500 miles). The Tomahawk sea-launched cruise missile (SLCM) and the Tomahawk ground-launched cruise missile (GLCM) had a length of 6.4 m (21 feet), a diameter of 53 cm (21 inches), and a range of 2,500 km (1,550 miles). Cruise missiles are self-propelled for the majority of their time in the air, flying in a relatively straight line and at lower altitudes thanks to a rocket propellant. Think of a ballistic missile's flight path as a large arc up and back down again, while that of a cruise missile — fired from a warship, for instance — is closer to a straight line. A depressed trajectory is non-optimal, as a lower and flatter trajectory takes less time between launch and impact but has a lower throw-weight.
The Soviet warheads often exceeded five megatons, with the largest being a 20- to 25-megaton warhead deployed on the SS-7 Saddler from 1961 to 1980 and a 25-megaton warhead on the SS-9 Scarp, deployed from 1967 to 1982. Modern cruise missiles are capable of traveling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory. Strategic missile, jet- or rocket-propelled weapon designed to strike targets far beyond the battle area.
