The Australian Department of Defence owns a munitions facility in New South Wales.
In 1991 Spantech was contracted to build nineteen Spantech 13 metre ESH at the facility.
The buildings were designed before the now famous Stack Frag Trials and feature the original tunnel entrance.
Spantech’s current range of ESH utilises a space-saving reinforced head wall which was proven in the full scale trials carried out at Woomera South Australia.
The Department of Defence facility is now operated by Australian Munitions, a business owned by Thales Australia Limited.
