Looking for pdf on APEX Ammunition

"...The Nammo 25mm APEX projectile is a next generation armour-piercing, high-explosive ammunition designed for use with the US F-35 Joint Strike Fighter aircraft. The projectile leaves the muzzle of the 4-barrelled GAU-12 weapon system with a velocity of around 1,000m/s and experiences a peak setback acceleration of almost 80,000g. Under these conditions, coupled with severe space restrictions, it is almost impossible to instrument the fuze in order to gain an understanding of the operation and interaction of components inside. Therefore, while physical testing can be used to confirm functionality of the fuze, it often offers only limited information for post analysis in the event of a failure to function...."

"...Thales Australia and Nammo have signed a long-term strategic teaming agreement to cooperate in the ordnance market.

The 10-year agreement expands on many years of cooperation between the two companies, and builds on a 2010 commitment to work together on ammunition for the F-35 fighter program, in particular on the Armor Piercing EXplosive (APEX) Norwegian ammunition concept. The agreement also covers Nammo’s special Reduced Ricochet Risk training round, plus Thales’s Armour Piercing Fragmenting & Incendiary (APFI) ammunition round. Under the increased scope of the new agreement, Nammo and Thales will work together in Research & Development, technology transfer, and component supply from Nammo, and further collaborate within the market place.

Chris Jenkins, Thales Australia’s CEO, said: “This cooperation will increase the range of domestic capability we are able to deliver to the Australian Department of Defence, and will boost our export potential by leveraging our world-class propropellant technology and Nammo’s specialist ammunition design and manufacturing heritage.”..."

"...Gun Ammunition Lethality. The U.S. Air Force is leading an evaluation of a new frangible armor piercing design for the F-35A ammunition; the Navy is evaluating existing PGU-32 semi-armor piercing high explosive incendiary ammunition for the F-35B and F-35C; and the Norwegian Ministry of Defense is evaluating a new armor piercing explosive ammunition for its F-35A variant and possibly the U.S. F-35B and F-35C variants. Terminal ballistic tests of all ammunition variants against common vehicle armor and masonry wall designs will start in FY13 and continue in FY14. All test data will feed Joint Munitions Effectiveness Models...."
