Here is a question about this article: Dell advertisements have appeared in several types of media including television, the Internet, magazines, catalogs and newspapers. Some of Dell Inc's marketing strategies include lowering prices at all times of the year, free bonus products (such as Dell printers), and free shipping to encourage more sales and stave off competitors.

Here is a question about this article: However, as stealth technology grows, so does anti-stealth technology. Multiple transmitter radars such as those from bistatic radars and low-frequency radars are said to have the capabilities to detect stealth aircraft. Advanced forms of thermographic cameras such as those that incorporate QWIPs would be able to optically see a Stealth aircraft regardless of the aircraft's RCS. In addition, Side looking radars, High-powered optical satellites, and sky-scanning, high-aperture, high sensitivity radars such as radio telescopes, would all be able to narrow down the location of a stealth aircraft under certain parameters. The newest SAM's have a claimed ability to be able to detect and engage stealth targets, with the most notable being the S-400, which is claimed to be able to detect a target with a 0.05 meter squared RCS from 90 km away.
What is the answer to this question: What is the most notable SAM that can detect a stealth target?
