This is the Russian MUV (MУВ), a High-Explosive (HE), mechanical, spring-operated, cocked-striker, PULL, initiator for landmines or Booby-Traps (BTP) which has been copied extensively. …

Explosives such as M1A1 land mines and M48 series projectiles fuses were manufactured on Crab Orchard during WWII. After WWII, excess explosives were disposed of in such a way that we don't know where all UXO are. Top Left: Diagram of new 1940s M1A1 landmine(with Right: M1A1 mine chassis found decades later on the Refuge.

What external markings on a grenade will tell you the fuse delay? There are no markings. What explosive hazards are purposely hidden and are difficult to identify?

Unexploded ordnance (UXO, sometimes abbreviated as UO) and unexploded bombs (UXBs) are explosive weapons (bombs, shells, grenades, land mines, naval mines, cluster munition, and other munitions) that did not explode when they were deployed and remain at detonative risk, sometimes many decades after they were used or discarded.

Mar 10, 2025 · Deterioration of detonators and fuses. The components designed to initiate explosions, including detonators and fuses, are susceptible to ageing. Factors such as corrosion, moisture ingress, and material fatigue can compromise their functionality, making the UXO more unpredictable and sensitive to disturbances.

Sep 4, 2023 · Unexploded ordnance, or UXO as it’s commonly known, is explosive ordnance which has been primed, fused, armed or otherwise prepared for action and which has been buried, dropped, fired, launched, projected, thrown, or placed in such a manner as to constitute a hazard to material, installations, operations, or personnel.

Not less than 1.9 million tons of bombs and ammunition were dropped over Germany during World War II. 70 years later, thousands of UXO are still remaining in the ground. As the fuses of these UXO’s are aging, this might result in uncontrolled detonations.

This is the Russian MUV-4 (MУВ-4), a High-Explosive (HE), hydraulic Delay (DLY) firing, cocked-striker, fuze intended for use with landmines or Booby-Traps (BTPs), designed to improve on …

Feb 22, 2018 · Bullets, hand grenades, artillery rounds, mines, missiles, bombs, fuses, warheads, mortars, TNT, C-4, and blasting caps are some examples. UXO can be found in current and former combat areas, military firing ranges, and training areas.

The UXO could be caused to detonate several ways: if the detonator is struck accidentally with sufficient force or is subjected to heat, static charge, friction or crushing; if a fuse containing a temporarily jammed cocked striker is jarred and the striker is released; similarly if a seized clockwork mechanism restarts; or if the sensitive iron ...
