What makes gardening difficult is that there are so many different types of soil to choose from, and it can be hard to know which will work best with certain plants. They execute endless practice runs and then review their in-flight decisions, attempting to hone their minds to select the best approach to any given scenario, particularly those that involve the use of deadly force. One set of designs would be boosted to altitude in front of the bombers and then flown towards them on a head-on approach at low speeds comparable to manned aircraft. A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. The American Nike Ajax was the first operational SAM system, and the Soviet Union’s S-75 Dvina was the most-produced SAM system. The first attempt at SAM development took place during World War II, but no operational systems were introduced.

The first serious consideration of a SAM development project was a series of conversations that took place in Germany during 1941. In February, Friederich Halder proposed a “flak rocket” concept, which led Walter Dornberger to ask Wernher von Braun to prepare a study on a guided missile able to reach between 15,000 and 18,000 m (49,000 and 59,000 ft) altitude. The first known idea for a guided surface-to-air missile was in 1925, when a beam riding system was proposed whereby a rocket would follow a searchlight beam onto a target. The first historical mention of a concept and design of a surface-to-air missile in which a drawing was presented, was by inventor Gustav Rasmus in 1931, who proposed a design that would home in on the sound of an aircraft’s engines. This evolution of design increasingly pushed gun-based systems into the shortest-range roles. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence.

Sveriges Television (in Swedish). In the immediate post-war era, SAM developments were under way around the world, with several of these entering service in the early- and mid-1950s. The directors of the Luftwaffe flak arm were not interested in manned aircraft, and the resulting disagreements between the teams delayed serious consideration of a SAM for two years. The lethal radius of a flak shell is fairly small, and the chance of delivering a “hit” is essentially a fixed percentage per round. Against late-war designs like the Boeing B-29 Superfortress or jet-powered designs like the Arado Ar 234, flak would be essentially useless. In general, these designs could be split into two groups. The infighting between various groups in the military also delayed development. Drones for Military vs. Hoyle, Craig (2024-06-12). “Why Swedish Gripen fleet is NATO’s new ACE off base”. Hoyle, Craig (2023). “World Air Forces 2024”. Flightglobal Insight. Against the Boeing B-17, which operated just within the range of the numerous German eighty-eights, an average of 2,805 rounds had to be fired per bomber destroyed. In his opinion, had they been consistently developed from the start, the large scale bomber raids of 1944 would have been impossible. Fortunately, I have escaped both dramas.

By this point serious studies by the Peenemünde team had been prepared, and several rocket designs had been proposed, including 1940’s Feuerlilie, and 1941’s Wasserfall and Henschel Hs 117 Schmetterling. These designs included the Feuerlilie, Schmetterling and Enzian. As the urgency of the problem grew, new designs were added, including Enzian and Rheintochter, as well as the unguided Taifun which was designed to be launched in waves. Increased environmental awareness, government regulation, the availability of monetary incentives and the rising cost of water are making the changeover to dual flush and low flow toilet designs more attractive to U.S. Some station managers, on their own initiatives, provided additional toilet facilities. Heavy shipping losses to kamikaze attacks during the Liberation of the Philippines and the Battle of Okinawa provided additional incentive for guided missile development. Albert Speer was especially supportive of missile development. Widely used modern examples include the Patriot and S-300 wide-area systems, SM-6 and MBDA Aster Missile naval missiles, and short-range man-portable systems like the Stinger and 9K38 Igla.
