First approved in 1996, the M919 is part of a large family of 25 x 137 mm rounds. Rounds with these dimensions can be fired from a number of different cannons:

  • Oerlikon KBA Cannon, found on ships, or as an anti aircraft gun, the Itallian Dardo IFV, and the Romanian ML1-84 IFV
  • GAU-12/U Bushmaster, found in the US AV-8 Harrier II aircraft, the US AC-130U Spooky Gunship aircraft, and several versions of US Light Assault Vehicle (LAV)
  • GAU-22/A, which will be introduced into the F-35 Joint Strike Fighter Aircraft
  • M242 Bushmaster, found on the Bradley Fighting Vehicle
  • Mauser Model E -Rheinmetal Rh206
  • Giat 25M811

In practice, however, each weapons platform is usually deployed with rounds tailored specifically to them. The M919 is known to be standard ammunition for the M2/M3 Bradley Fighting Vehicle, but is not thought to be commonly fired from the other listed platforms. The M919 was developed by General Dynamics-Ordnance and Tactical Systems as a replacement for the M719 APDS-T round (made with a tungsten penetrator).

The M919 weighs 454g, and the long rod uranium penetrator itself weighs 98g. There is also a version available with a tungsten penetrator.

In early 2010, ICBUW broke the story that the United States was moving away from using uranium medium calibre rounds. As the Bradley is intended to remain in service until the mid 21st century, it is unclear whether a different round will be brought into service, or whether the US has sufficient stockpiles of the M919 for all future scenarios. Nevertheless, at the time of writing, the range used for test firing the M919 was much of the way through an extensive decontamination programme, and the round is unlikely to be manufactured again in the future.

At the time of the 1991 Gulf War, the US Navy AV-8 Harrier II aircraft were equipped with another 25 x 137 uranium round, the PGU-20, which was typically used in a 50-50 mix with the PGU-25 High Explosive round. However, it seems that the PGU-20 is no longer in service.

It is also concievable that US Marine LAV 25s equipped with the GAU-12 have also fielded the M919, but it seems unlikely at present.
