SDI was not just lasers; in this Kinetic Energy Weapon test, a 0.25-ounce (7 g) Lexan projectile was fired from a light-gas gun at a velocity of 23,000 feet per second (7,000 m/s; 16,000 mph) at a cast aluminum block. Another criticism of SDI argued that it would be inconsistent with existing treaties.
Roman numerals: for example the word "six" in the clue might be used to indicate the letters VI; The name of a chemical element may be used to signify its symbol; e.g., W for tungsten; The days of the week; e.g., TH for Thursday; Country codes; e.g., "Switzerland" can indicate the letters CH; ICAO spelling alphabet: where Mike signifies M and ...

A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon , which directs focused energy toward a target using atomic scale particles.
SDI - Strategic Defense Initiative, or simply titled SDI and sometimes known as Global Defense, is a horizontally scrolling shooter produced and released internationally in arcades by Sega in 1987. It was ported to Amiga , Amstrad CPC , Atari ST , Commodore 64 , Master System , and ZX Spectrum .
The report also noted that the energy requirements for a directed energy weapon used as a BMD asset was much higher than the energy needed for the same weapon to be used against those assets. [78] This meant even if the SDI weapons could be successfully developed, they could be attacked by similar weapons that would be easier to develop.
The device was originally built in the 1970s for high-power x-ray research, was later re-directed to studies for the Strategic Defense Initiative (SDI), and is now being used for magnetized target fusion research. Shiva Star was named after the Hindu god Shiva, partly because its prototype originally had four "arms"; it later got six "arms
