Overview

The 300 kt warheads of the ASMP supersonic air-to-surface missile. The TN 80 armed the Mirage IVP from 1985 to 1991; the TN 81, introduced in 1988, armed Mirage 2000N and Super Étendard aircraft until the TNA replaced it around 2010.

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.
