🎬A ministry film documenting 'Special Weapons' tests on the wall targets at Ashley Walk Bombing Range.

Over 3,000 acres of Ashley Walk were fenced off during the Second World War. Within this area many types of air delivered bombs were tested. Special concrete structures were built to assess the various bomb's effectiveness. There is still visible evidence of these structures and the scars remain from the largest weapons.

"Highball" was considered one of the smaller 'special weapons'. These tests were using actual size casings but without the high explosive. The footage here is thought to be from late 1942 and early 1943.
