Bombrini-Parodi-Delfino (better known as BPD), was a chemical company founded in 1912 by Giovanni Bombrini and Leopoldo Parodi-Delfino to produce gunpowder and explosives. Around its location in Colleferro (south of Rome) soon grew a small town attracting manpower from the nearby farms. After World War I, BPD expanded its activities on fertilizers and cement at nearby Segni (Società Calce e Cementi). In 1938 an explosion in the gunpowder plant killed 60 people.da [http://www.elenabrunetti.it/cartella/colleferro/esplosione.htm www.elenabrunetti.it/cartella/colleferro/esplosione.htm] {{webarchive |url=https://web.archive.org/web/20090409162459/http://www.elenabrunetti.it/cartella/colleferro/esplosione.htm |date=April 9, 2009 }} After World War II, BPD diversified into metalworking, textiles and chemistry. The last remaining owner, the Parodi-Delfino family, entered a joint venture with SNIA-Viscosa in 1968.Determinants in the evolution of the European chemical industry, 1900-1939, Anthony S. Travis, Kluwer Academic Publishers, Dordrecht, 1998, p.293. SNIA's chemical division was thereafter named SNIA BPD until BPD was sold to Simmel Difesa, when it was renamed SNIA SpA.[http://www.snia.it/en/profilo/la_storia/la_storia.php SNIA history.] {{webarchive |url=https://web.archive.org/web/20080406051620/http://www.snia.it/en/profilo/la_storia/la_storia.php |date=April 6, 2008 }}

BPD contribution to missile research

BPD played an important role in developing missile solid fuels. In 1952, on behalf of the Aeronautica Militare, BPD patented a solid fuel based on nitro-glycerine and cellulose nitrate, the first step in developing experimental missiles on an industrial scale. The Aeronautica_Militare also contracted BPD to develop a meteorological missile, called the 160-70, employing two propulsion systems. The 160-70 was successfully employed in many launches between 1961 and 1963. In 1961 state and private companies merged; publicly owned Finmeccanica and the private firms BPD and FIAT were incorporated into the Società Generale Missilistica Italiana.

SNIA-BPD also developed a series of air-to-surface rockets in the 1980s as part of the Medusa rocket system. The rockets were of 51-mm, 81-mm, and 122-mm caliber.[http://www.janes.com/articles/Janes-Air-Launched-Weapons/SNIA-BPD-81-mm-Medusa-rocket-system-Italy.html Jane's article on Medusa.]
