US Navy to Get 20mm Training Ammunition from Alliant

Aerospace and defence company Alliant Techsystems (ATK) will deliver 20mm and 30mm tactical and training ammunition for the US Navy and Air Force, respectively, under two new contracts worth $31m.

The Minneapolis-based company will deliver 20mm mk244 armour-piercing rounds for the US Navy 20mm Phalanx anti-missile system, while 30mm PGU-15 target practice ammunition for the US Air Force’s A-10 Warthog.

The navy deliveries will begin in December 2009, while delivery of ammunition for the air force will start in 2010 under the multiple-year contract.

The fast-reaction, rapid-fire 20mm Phalanx close-in gun system provides US Navy ships with a terminal defence against anti-ship missiles.
