US abbreviation GLD for a bomb fuze
- Thread starter Antoon
- Start date
GLD = "ground level detonation" an abbreviation encountered sometimes in operational reports of 1944-45. This could correspond to a number of fuzing configurations: extended probe fuzes, fuzes with pressure sensitive diaphragm actuated detonators or even the early proximity fuzes.
Dreamk,
Thanks for the answer.
Could the abbreviation also be used with the nose impact fuze (AN-)M103-serie on instantaneous setting, so 0 sec. delay?
I think yes, because the used it also on the 260 lb. fragmentation bomb, and that has to detonated also above ground.

Generally when using an instant fuze the mention written in operational report is "instantaneous" - in fact even with the M103 series, the detonation occurs together with penetration into the ground.
It's the reason why the M1 / M1A1 fuze extension probe was sometimes installed on the M 103 to insure its detonation over the ground ('daisy cutter"), a fore-runner of today superquick fuzes .
Historically the fuze extension was initially developed for US Navy bombs, equipping the Mk219 fuze from 1943 onwards, probably inspired by a similar British pattern, used before that by the Australian squadrons serving in the Western desert.
The T90 VT fuze introduced in 1944 was devised to exploded at 10ft above the ground.
However in the absence of more information the GLD designation remains open to speculations, without any precise identification.
