Point Detonating Fuzes M739 and M739A1 are selective superquick and 0.05 second delay (M739) or auto-delay (M739A1) impact fuzes designed for use in all standard HE artillery 4.2 inch Mortar, 105mm through 8 inch Howitzers and 175mm Guns. The M739 series fuzes are the latest improved version of the selective impact fuzes.

This is the American M739, a High-Explosive (HE), Point-Detonating-Super-Quick (PDSQ), spin-stabilised, selective or 0.05-second Delay (DLY) Impact (IMP) projectile fuze improved versions of the M557 and M572 being less sensitive to rain.

The M739A1 is the standard U.S. Army point detonating fuze used on 105mm, 155mm, 175mm, and 203mm artillery projectiles and mortar rounds. It has a 99.2% reliability rate after producing over half a million fuzes.

The M739A1 is a US-developed point detonating (PD) and delay fuze used with spin-stabilised explosive (HE) and bursting-smoke (chemical agent) artillery projectiles. The design of the M739A1's nose area makes it suitable for firing in even …

The M739 is a US-developed point detonating (PD) and delay fuze used with spin-stabilised high explosive (HE), bursting-smoke (chemical agent) and bursting practice projectiles. The M739 was developed to replace fuzes such as the M508 PD series, along with the M557 and the M572 PD and delay series of fuzes.

2017年8月28日 · The M739A1 PD/DLY Fuze is the Army's primary fuze for 105mm and 155mm bursting projectiles for point detonating and delay fuze functions. The M739A1 PD/DLY fuze contains an Impact Delay Module (IDM)...

The Fuze, Point Detonating (PD) M739/M739A1 N340 is the latest improved version of the selective impact fuzes for use with bulk loaded high explosive or burster type projectiles. This fuze is fired from the M198 155mm Medium Towed Howitzer and the M777 Lightweight Towed Howitzer Weapon System.
