Hi There, This isn't a 'parachute bomb'. It's commonly referred to as a 'daisy cutter' and was used to clear large areas of ground in an instant, most often to create landing zones for helicopters. 

The long probe detonates the bomb prior to its hitting the ground, ensuring the blast remains wholly above ground causing maximum damage to vegetation, etc but not to the ground itself.
