Almost exactly 75 years ago, on August 18, 1943, the USS Abner Read was rocked by a severe explosion.
The blast — which most historians say was likely a Japanese mine — tore the 75-foot stern section of the ship clean off. The stern plummeted to the depths of the ocean, taking the lives of 71 US sailors with it, while other US ships rushed to the rescue.
Though the rest of the USS Abner Read was miraculously saved and towed into port, the original stern was thought to be lost forever — until now.
On July 17, a team of scientists, divers, and archaeologists partially funded by the National Oceanic and Atmospheric Administration discovered the missing section of the ship in just under 300 feet of water off the coast of Kiska Island, a part of Alaska's remote Aleutian Islands chain.
Here's what the expedition to discover the long-lost wreck was like.
The Aleutian Islands campaign was one of the few major World War II battles fought on US soil. But the area's place in WWII history is often forgotten, perhaps because the islands are remote, cold, and difficult to get to. That's part of the reason the Abner Read lay undiscovered for decades.
In June 1942, Japanese forces took over and occupied a pair of remote Aleutian islands: Kiska and Attu.
American forces quickly called in a number of battleships and destroyers, including the USS Abner Read, as well as heavy air power to repel the Japanese invasion.
By August 1943, the USS Abner Read was part of a bombing campaign on the two Japanese-occupied islands.

American forces ultimately repelled the Japanese occupiers, but suffered a heavy loss of life in the little-known battle.
To get to Kiska, the team of NOAA-sponsored researchers flew to Adak, a remote community in the Aleutians. Then they traveled 250 miles over rough seas to Kiska on a ship called the R/V Norseman II.
Operating the technology in stormy, cold, and wet conditions proved to be a constant challenge for the team.
"The 17 hours of daylight that now occur at this high latitude were both a godsend and a curse as there was ample time to work, but little time to sleep," Eric Terrill, an oceanographer and the leader of the expedition, said in a mission log.
To narrow down the search area, the team looked at historical charts and reports, then used a fleet of Remus 100 autonomous underwater vehicles (AUVs) to help them locate the wreckage.
When they found promising images from the AUVs, the team sent out divers to scan for more clues.
The team also surveyed Kiska, which is still full of WWII wreckage. They found these cannons and another sunken warship off the coast.
"We hiked the hillside and saw remnants of a battlefield with barbed wire, overturned military vehicles, hillside cannons, underground bunkers, craters from bombing blasts, and unkempt trails or roads," Erik White, an engineer on the expedition wrote in a mission log.
While beautiful, the island is a frigid, haunting monument to a battle that claimed the lives of almost 5,000 Japanese and American men.
