M739A1 Point Detonating/Delay (PD/DLY) Fuzeview on SAM.gov

The M739A1 PD/DLY Fuze is the primary fuze for 105mm and 155mm bursting artillery projectiles for point detonating or delay fuze functions. SOCOM utilizes the M739A1 PD/DLY Fuze for training operations only. The US Army and USMC utilize the M739A1 PD/DLY Fuze for both training and tactical operations. The M739A1 PD/DLY Fuze is composed of a one-piece solid aluminum body with a standard 2-inch threaded base. Five modular subassemblies are incorporated as the functional fuze components. The M739A1 PD/DLY Fuze contains an Impact Delay Module (IDM) assembly that provides fuze initiation delay based upon the completion of mechanical actions caused by projectile deceleration. In the delay mode, the fuze will function 3-6 milliseconds after passing through the target. Function occurs when a spring-loaded firing pin is released. There are no explosive components contained within the IDM. The outer surface of the M739A1 PD/DLY Fuze is anodized green to distinguish it from other fuzes in the inventory for Explosive Ordnance Disposal (EOD) purposes.Solicitation Released on 15 May 2025 with Response Date 14 July 2025.Amendment 0001 released on 11 July 2025 with Response Date 29 July 2025.
