Analyst Note:
The M117 series of air-delivered bombs were historically referred to as ‘demolition bombs’, due to the more substantial blast effect they offer in comparison with so-called ‘general-purpose bombs’. This is achieved through the use of more energetic explosive compositions, such as Tritonal or Minol, which incorporate an oxidiser (typically aluminium powder). Today, munitions using such compositions are sometimes considered in the loose category of ‘enhanced blast munitions’, but the distinction between demolition and general-purpose bombs has largely disappeared.

Analyst Note:
This image depicts an M117-series unguided aerial bomb. Belonging to a class of weapons referred to as ‘demolition bombs’—which use Tritonal or similar explosive compounds to generate a more powerful blast effect than TNT or Composition B—the M117 is an American design which dates to the Korean War era and is rarely seen in service with modern armed forces.
