Fan Song radars were provided targets by higher echelon radars, such as the Spoon Rest radar. These dishes provided azimuth and altitude information for targets, which was then relayed to the missiles. This radar was also designed to be mobile- several large dishes were mounted to a single trailer. Each missile battery was to contain six launchers and one RSNA/SNR-75 “Fan Song” radar. The missile itself was launched from a SM-90 single rail launcher, which was carried by a transloader trailer and pulled by a Zil truck. The new missile was designed from the start to be more mobile than its predecessor. This missile, the SA-2e, was armed with a 295kg warhead which had an estimated yield of 15 kilotons, the same explosive power as the bomb used against Hiroshima. A nuclear-armed variant of the SA-2 was produced, intended for use against bomber formations. At lower altitudes against fighter-bombers, the blast radius was lethal out to 65m. The blast radius of the warhead depended on the altitude of detonation- at the high levels where U-2 reconnaissance planes flew, it could be as much as 244m. Different fuses, included proximity, contact and command fuses were produced for use. The warhead for most of the earlier Guideline variants weighed 195kg, and was usually high explosive-fragmentation. The first contained solid propellant to accelerate away from the launch site, and the second contained a hypergolic liquid propellant. In 1953, the Almaz design bureau presented its missile design, which had been created by Pyotr Grushin. Subsequently, it was decided to begin designing a newer missile which would be better suited for tactical operations. However, almost as soon as it was introduced, it was realized that there were problems with the new missile- it was limited to one location (the system was fixed and could not be moved), it was effective against large formations but not against smaller groups of aircraft, and it had limited targeting capabilities. In response to the US bomber threat, the Soviets began building surface-to-air missiles. While the Soviets possessed a substantial number of fighter aircraft, the Soviets felt that their numbers were not great enough to stop all of the bombers. In the 1950s, with Cold War tensions only increasing, the United States had begun building large numbers of jet-powered bombers which were capable of aerial refueling and could fly all the way to their potential targets in the Soviet Union. The Guideline was destined to become the most widely-distributed SAM during the Cold War. The most dreaded of these came in the form of the SA-2 “Guideline” SAM, a telephone-pole length missile which inflicted many losses on US aircraft over the course of the war. Hopefully, now you have a little more context to decide which one works best for your business.For American fighter-bomber pilots flying above North Vietnam in the late 1960s, ground fire and Surface-to-Air-Missiles (SAMs) were far more feared than the occasional MiG. There are pros and cons to both transport options. Transloading can ensure a lot more capacity and more competitive prices, however if your shipment is extremely time sensitive, you should keep in mind that it can take longer for goods to be transferred between trailers. In this case, after your cargo arrives at the border, it will be moved from one box to another in a specialized warehouse. Therefore, transloading has become the most common option for shippers. The reason why it is not used more often is due to the low availability of carriers for this service, and considerably higher prices. Through-trailer is usually only recommended for fragile, sensitive material that should be handled with great care. This process tends to involve four actors: a Mexican carrier, a drayage company, a transloading facility, and an American carrier. Transloading is the process of transferring freight from one trailer to another during a border crossing. In fact, there are usually three drivers involved in the process: a Mexican driver, a border driver, and an American one. However, this doesn't mean that your cargo is handled by only one driver. Through-trailer happens when the load is transported in the same trailer for the entirety of the process, from the pick-up point to the final destination. First, let's start with some basic definitions:
