TATB, triaminotrinitrobenzene or 2,4,6-triamino-1,3,5-trinitrobenzene is an aromatic explosive, based on the basic six-carbon benzene ring structure with three nitro functional groups (NO2) and three amine (NH2) groups attached, alternating around the ring.

TATB is a very powerful explosive (somewhat less powerful than RDX, but more than TNT), but it is extremely insensitive to shock, vibration, fire, or impact. Because it is so difficult to detonate by accident, even under severe conditions, it has become preferred for applications where extreme safety is required, such as the explosives used in nuclear weapons, where accidental detonation during an airplane crash or rocket misfiring could potentially detonate the fissile core. All British nuclear warheads use TATB-based explosives in their primary stage.[1] According to David Albright, South Africa's nuclear weapons used TATB to increase their safety.[2]

TATB is normally used as the explosive ingredient in plastic bonded explosive compositions, such as PBX-9502, LX-17-0, and PBX-9503 (with 15% HMX). These formulations are described as insensitive high explosives (IHEs) in nuclear weapons literature.

Though it could theoretically be mixed with other explosive compounds in castable mixtures or other use forms, the applications for such forms would be unclear since they would largely undo the insensitivity of pure TATB.
