UPI is reporting that the U.S. Army has awarded Orbital ATK a $16 million contract for first-phase development of a new 120mm multi-purpose tank round.  According to the article, Orbital ATK said the 120mm Advanced Multi-Purpose, XM1147 High Explosive Multi-Purpose with Tracer cartridge will replace four existing rounds, including those for defeating armor and breaching reinforced walls.  The article does not specify which four rounds this new munition will replace.  A timeline for this new ammunition development was not disclosed.  Orbital ATK and the U.S. Army earlier this year finished qualification for the M829E4, creating the Army’s fifth generation 120mm kinetic energy round.
