Unlike the heavier guns, these smaller weapons are in widespread use due to their low cost and ability to quickly follow the target. Classic examples of autocannons and large caliber guns are the 40 mm autocannon and the 8.8 cm FlaK 18, 36 gun, both designed by Bofors of Sweden. Artillery weapons of this sort have for the most part been superseded by the effective surface-to-air missile systems that were introduced in the 1950s, although they were still retained by many nations. The development of surface-to-air missiles began in Nazi Germany during the late World War II with missiles such as the Wasserfall, though no working system was deployed before the war's end, and represented new attempts to increase effectiveness of the anti-aircraft systems faced with growing threat from [bomber]s. Land-based SAMs can be deployed from fixed installations or mobile launchers, either wheeled or tracked. The tracked vehicles are usually armoured vehicles specifically designed to carry SAMs.
How can land-based SAMs be deployed?
A: from fixed installations or mobile launchers

By the late 2000s, Dell's "configure to order" approach of manufacturing—delivering individual PCs configured to customer specifications from its US facilities was no longer as efficient or competitive with high-volume Asian contract manufacturers as PCs became powerful low-cost commodities. Dell closed plants that produced desktop computers for the North American market, including the Mort Topfer Manufacturing Center in Austin, Texas (original location) and Lebanon, Tennessee (opened in 1999) in 2008 and early 2009, respectively. The desktop production plant in Winston-Salem, North Carolina, received US$280 million in incentives from the state and opened in 2005, but ceased operations in November 2010. Dell's contract with the state required them to repay the incentives for failing to meet the conditions, and they sold the North Carolina plant to Herbalife. Most of the work that used to take place in Dell's U.S. plants was transferred to contract manufacturers in Asia and Mexico, or some of Dell's own factories overseas. The Miami, Florida, facility of its Alienware subsidiary remains in operation, while Dell continues to produce its servers (its most profitable products) in Austin, Texas. On January 8, 2009, Dell announced the closure of its manufacturing plant in Limerick, Ireland, with the loss of 1,900 jobs and the transfer of production to its plant in Łodź in Poland.
What plant did Dell close in Texas?
A: Mort Topfer Manufacturing Center
