Use in Military Aviation and In Space
Air-based g-suits were very common in NATO aircraft of all nations from the 1950s onwards and are still in common use today.
Later jets such as the F-15 Eagle, F-16 Fighting Falcon, F/A-18 Super Hornet, Eurofighter Typhoon and the Dassault Rafale can sustain high g loads for longer periods, and are therefore more physically demanding. However, by using a modern g-suit in combination with anti-g strain techniques, a pilot can now be expected to sustain flight forces of up to nine g without blacking out.
Astronauts wear g-suits similar to aviators but face different challenges due to the effects of microgravity. Aviator g-suits apply uniform pressure to the lower legs to minimize the effects of high acceleration but research from the Canadian Space Agency implies there might be a benefit in having a suit for astronauts that uses a "milking action" to increase blood flow to the upper body.

Famous quotes containing the words military and/or space:
“The military mind is indeed a menace. Old-fashioned futurity that sees only men fighting and dying in smoke and fire; hears nothing more civilized than a cannonade; scents nothing but the stink of battle-wounds and blood.”
—Sean O’Casey (1884–1964)
“Finally she grew quiet, and after that, coherent thought. With this, stalked through her a cold, bloody rage. Hours of this, a period of introspection, a space of retrospection, then a mixture of both. Out of this an awful calm.”
—Zora Neale Hurston (1891–1960)
