How WW2 bombs across the Pacific are found and destroyed, decades after war

In the Marshall Islands, decades after World War II, unexploded ordnance (UXO) from the conflict continues to pose a significant threat to local communities. The US and various organizations are investing millions to locate and safely dispose of these dormant bombs, which are scattered across the islands. Recent efforts include a $1.7 million project launched by the US State Department in collaboration with the Golden West Humanitarian Foundation, focusing on four atolls prioritized by the Marshall Islands government. Local residents, such as Wilbert Alik, play a crucial role in these operations, ensuring safety protocols are followed and cultural sites are preserved. The cleanup efforts are vital for community safety, as many residents live in constant caution of hidden explosives while engaging in daily activities like farming. Training programs are being implemented to educate locals on recognizing and avoiding UXOs, although not all communities have received this training yet. The ongoing work aims to clear areas for community development, allowing residents to build essential facilities and live without the fear of encountering unexploded bombs. The project is part of a broader initiative to address the legacy of war in the Pacific, with estimates suggesting that hundreds of thousands of unexploded ordnance remain in the region.

- The Marshall Islands are still affected by unexploded ordnance from WWII, posing safety risks.

- A $1.7 million project aims to locate and dispose of these bombs with local and US support.

- Local residents are involved in cleanup efforts, ensuring safety and cultural preservation.

- Training programs are being developed to educate communities about UXO risks.

- The initiative seeks to enable community development and improve safety for residents.

AI: What people are saying
The comments discuss the ongoing issue of unexploded ordnance and its global implications.
  • Many countries, including Germany and Laos, continue to deal with the dangers of unexploded bombs and munitions from past conflicts.
  • Cluster munitions, particularly in Laos, pose a significant threat, with millions of unexploded bomblets still causing casualties.
  • There are concerns about the environmental impact of dumped munitions in oceans and lakes worldwide.
  • Historical accounts highlight the presence of unexploded bombs in various locations, including the Thames River in London.
  • Questions arise regarding the stability and potential risks of explosive compounds over time.

What is often underestimated is the sheer amount of ammunition still found. On German mainland alone about 5000 WW2 bombs are destroyed every year. The "Kampfmittelräumdienstfahrzeug" is common sight at construction sites. Luckily accidents are rare and there are only between 1 and 2 self detonations per year.

From what I've heard from my Vietnamese colleagues the situation there is similar.

Related topic that I dug into was “how long did destroyed equipment lay around during WW2?”.

There were tank battles (especially in Russia) where hundreds of tanks on both side were effectively destroyed. Now add in trucks, towed and mobile guns, etc.

I was curious. Were they abandoned and scavenged for money after the war? Did they stay there and rust until years as the war? Did militaries take them for spare parts?

Turns out that equipment was very quickly cleaned up when possible. Usually within days/weeks.

Came across this incredibly detailed website with some amazing pictures and in depth information: https://wwiiafterwwii.wordpress.com/2017/02/20/cleaning-up-a...

Much worse are cluster munitions. In Laos alone there are tens of millions of the 'bomblets', dropped in the 60s and 70s - without any war declared on Laos, still regularly killing and maiming thousands of people, primarily children. [1]

And then countless tons of ammunitions are dumped in seas all around the world (and in Swiss lakes). This Google map has info on chemical weapons dump site, stating 1.6 million tons dumped:

There are 1.4KT of bombs sitting onboard just 1 ship at the bottom of the river Thames today[1]. As for free fall bombs, my great grandfather recounted to me the time he stood on the banks of the river at Battersea and watched them fall "like raindrops" into the dark waters. There they all sit, deep in the mud[2]. [1] https://en.wikipedia.org/wiki/SS_Richard_Montgomery [2] https://theworld.org/stories/2015/04/10/map-shows-where-all-...

Here's one from last week, way way across the Pacific in Ireland:

Do the explosive compounds decompose into more or less volatile things with time? Or are they relatively shelf stable and the bulk material has roughly the same potential as when it was dropped?
