MIRACL

MIRACL, or Mid-Infrared Advanced Chemical Laser, is a directed energy weapon developed by the US Navy. It is a deuterium fluoride laser, a type of chemical laser.

SeaLite Beam Director, commonly used as the output for the MIRACL.

The MIRACL laser first became operational in 1980.[1] It can produce over a megawatt of output for up to 70 seconds,[2] making it the most powerful continuous wave (CW) laser in the US.[3] Its original goal was to be able to track and destroy anti-ship cruise missiles, but in later years it was used to test phenomenologies associated with national anti-ballistic and anti-satellite laser weapons. Originally tested at a contractor facility in California, as of the later 1990s and early 2000s, it was located at a facility (32.632°N 106.332°W / 32.632; -106.332) in the White Sands Missile Range in New Mexico.[4]

The beam size in the resonator is about 21 cm (8.3 in) high and 3 cm (1.2 in) wide.[2] The beam is then reshaped to a 14 x 14 cm (5.5 in x 5.5 in) square.[2]

Amid much controversy in October 1997, MIRACL was tested against MSTI-3, a US Air Force satellite at the end of its original mission in orbit[5] at a distance of 432 km (268 mi).[6] MIRACL failed during the test and was damaged[7] and the Pentagon claimed mixed results for other portions of the test. A second, lower-powered chemical laser was able to temporarily blind the MSTI-3 sensors during the test.[8]
