Overview

The thermonuclear warhead of the ASMP-A air-launched missile carried by France’s Rafale and Mirage 2000N aircraft, introduced in 2010; 54 were produced. Its yield is not published and is reported to be up to about 300 kt.

Effect radii: estimates

Calculated for 300 kt

Fireball, maximum radius
≈ 600 m
Initial radiation, 500 rem (5 Sv)
≈ 2.5 km
Blast 5 psi: most buildings collapse
≈ 4.8 km
Thermal: third-degree burns
≈ 6.9 km
Blast 1 psi: windows shatter
≈ 15 km

Estimated ground ranges for an air burst at the optimum height over flat, open ground, computed from the yield with standard scaling laws. These are not measurements: real effects depend on the height of burst, terrain, buildings and weather.
