Dunnite, also known as Explosive D or systematically as ammonium picrate, is an explosive developed by Major Dunn in 1906.[2] Ammonium picrate is a salt formed by reacting picric acid and ammonia. It may be noted as the first explosive used in an aerial bombing operation in military history, performed by Italian pilots in Libya in 1911.[3],La Stampa, November 2, 1911. It was used extensively by the United States Navy during World War I.[4]

Though Dunnite was generally considered an insensitive substance, by 1911 the United States Army had abandoned its use in favor of other alternatives.[5] The Navy, however, used it in armor-piercing artillery shells and projectiles, and in coastal defense.

Dunnite typically did not detonate on striking heavy armor. Rather, the shell encasing it would penetrate the armor, after which the charge would be triggered by a fuse .

In 2008 caches of discarded Dunnite in remote locations were mistaken for rusty rocks at Cape Porcupine, Newfoundland and Labrador, Canada.[6][7]
