Hexanitrostilbene (HNS), also called JD-X, is a heat resistant high explosive developed at the Naval Ordnance Laboratory in the 1960s. Other names include 1,1'-(1,2-ethenediyl)bis[2,4,6-trinitrobenzene]; 1,2-bis-(2,4,6-trinitrophenyl)-ethylene; hexanitrodiphenylethylene.

It is commercially produced by oxidizing trinitrotoluene (TNT) with a solution of sodium hypochlorite. HNS boasts a higher insensitivity to heat than TNT, and like TNT it is very insensitive to impact. When casting TNT, HNS is added at 0.5% to form erratic micro-crystals within the TNT which prevent cracking.

HNS was the main explosive fill in the Mortar grenades used as part of the Apollo Lunar Active Seismic Experiments.^[1]

Its heat of detonation is 4 kJ/g.^[2]
