More Precision for Navy Guns

by Matt Cox on December 6, 2012

U.S. Navy combat ships equipped with 5-inch guns are about to get more lethal. Next fall, ATK will begin delivering the new Multi-Option Fuze, Navy, or MOFN, for ammunition fired from MK 45 weapon systems.

Army Contracting Command just awarded ATK a five-year contract worth $84 million to produce the MK 437 MOFN for the Navy. The Army’s Joint Products Office manages the program for the Navy.

These specialized fuzes provide proximity, precision time, delay and point detonating impact options in a single fuze, ATK officials maintain. The inductive fuze setting feature also optimizes MOFN for use with automated ammunition handling equipment.  MOFN will be used on projectiles fired in the MK 45 Single Lightweight Gun Mount on Navy cruisers and destroyers.

“ATK is pleased to add MOFN to our portfolio of fuze production programs.  MOFN leverages ATK’s design, development and production experience, providing the U.S. Navy with an affordable, reliable fuze for its 5/54 caliber ammunition,” said Dave Fine, ATK’s Director of Fuzing and Warhead programs, in a recent ATK press release.

The first order on this contract is for approximately $13 million; deliveries are scheduled to begin in November 2013.

Production of this fuze will occur at the Allegany Ballistics Laboratory facility in Rocket Center, W. Va.  The lab is a U.S. Navy-owned, ATK-operated facility specializing in advanced manufacturing technologies for a variety of programs supporting current and future U.S. industrial base needs in advanced fuzing and integration, conventional munitions assemblies, solid rocket motor propulsion, and advanced material structures.
