bombproof
Survives any explosion
Bombproof describes something built to withstand bomb explosions: a bombproof shelter, bombproof bunker.
Figuratively, it means completely reliable or immune to failure—a bombproof plan has no vulnerabilities, a bombproof excuse can't be challenged.
In equestrian contexts, a bombproof horse stays calm despite loud noises or sudden movements: She's looking for a bombproof mount for her nervous daughter.
