how come the FAB-100 dont have delay fuzes? I asked grok about it and he replied:
The AVU-ET fuze, compatible with bombs like the OFAB-100-120 (a fragmentation variant closely related to the FAB series), provides "point detonating and inertia action, ignition SQ and two delay modes."
The AVU-ETM fuze offers explicit delay timings, such as "Setting Assault – 10…14.5" seconds after impact, in addition to near-instantaneous options (e.g., 0.01–0.09 seconds).
