Fuzing systems are the primary components that initiate the charge to munitions and ordnance system and are highly critical to our U.S. military and international allies. These can be highly complex systems used for ground, water, or air applications and must not only be operator safe but extremely reliable in all conditions. These are mission-critical components and assemblies which require flawless performance in all conditions. They are often manufactured in combination with safing and arming devices which further protect our military personnel. The fuzing and ordnance systems can be mechanical and electro-mechanical in nature and designed for reliability, accuracy, and high performance.
Fuzes are used by all branches of the U.S. military. Examples include:
- Army –
- Artillery munitions fuzes
- M732 multi option fuze for 105mm and 155mm projectiles
- M782 MOFA fuze for the M795 155mm projectile
- Mortar systems
- M52 fuze for 60mm and 81mm mortars
- M525 super quick point detonating (SQPD) fuze for 60mm and 81mm mortars
- M734 multi option fuze for the M933 120mm cartridge
- Indirect infantry fire systems
- 40MM rounds for the MK-19 and M203 / M230
- Artillery munitions fuzes
- Navy
- Fuzes for naval guns (e.g., Mark 88 round for the Mark 45 Mod 4 lightweight gun system)
- Naval mines fuzes
- Naval aviation utilizes electro-mechanical and all electric fuzes on their ordinance (such as the FMU-143 and FMU-152 for the GBU-31A and GBU-24 series munitions)
- DB-139 is the new all-electric fuze for Air Force and Navy GBU applications
- Air Force –
- Marines – similar to applications by the Army (on artillery and mortar systems) and Air Force / Navy (on bombs and missiles)
