Three WWII aircraft that were shoot down during a decisive U.S. victory in the Pacific Ocean were missing for decades . Now , 76 years later , they have been found .
A retrieval operation discovered opus of the long - lost planes at the bottom of Truk Lagoon in Chuuk State , part of the Federated States of Micronesia .

Punched holes in a panel from an SBD-5 Dauntless dive bomber are visible in wreckage resting on the floor of Truk Lagoon near the main debris site.
Hundreds of U.S. aircraft establish from toter on Feb. 17 , 1944 , during " Operation Hailstone , " pommel a Nipponese naval base in Truk Lagoon that was so well bastioned it was known as " the Gibraltar of the Pacific,“representatives of the retrieval expedition enunciate in a argument .
When the smoking from the two - day battle cleared , more than 250 Nipponese aircraft and nearly 50 ships were destroyed . But 30 American aircraft were also turn a loss , along with 23 aviators and crewmen . The three planes that were recovered go undetected until 2019 , even though the spot is a popular finish for diver , according to the statement .

U.S. Navy Grumman Avengers torpedo bombers flying from the USS Intrepid in 1944.
The missionary work to retrieve the plane was led by scientists and military volunteer withProject Recover , a partnership between researchers at the University of Delaware ; Scripps Institution of Oceanography at the University of California San Diego ; and the BentProp Project , a secret arrangement of divers , aeronaut and historiographer dedicated to finding WWII service members missing in military action in the South Pacific . Since 2012 , Project Recover has channel underwater search for missing U.S. military craft and personnel , combine data from official records , eyewitness accounting and underwater hunting technologies such as sonar , thermal cameras and diving robots , fit in to the project ’s website .
Launched from the American aircraft carriers USS Enterprise and USS Intrepid during Operation Hailstone , two Dauntless dive bombers and one Avenger torpedo hero sandwich were among the miss U.S. planes . Researchers suspected that the planes sank in Truk Lagoon based on consultation with Chuuk island-dweller , prescribed reports and memoirs from survivor of the battle , enunciate Colin Colbourn , lead historian with Project Recover .
One lucky objet d’art of information come from a U.S. serviceman — an plane machine gunner in Operation Hailstone — who mentioned in a memoir that he visualise one of the Dauntless dive wedge struck just as he was firing at a Nipponese transport ship , which also sank . The historiographer quickly substantiate that pinpointing the location of that recessed ship could lead them to the wreckage of the lost bomber , Colbourn told Live Science .

A coral-covered propeller of an SBD-5 Dauntless dive bomber rests on the sand in Truk Lagoon.
" We were able to line up this piece of the puzzle with this other piece of the teaser , in ordination to say , ' OK , rent ’s sharpen our search around this ship . ' And that was actually where we terminate up finding this airplane , " Colbourn said .
Underwater surveys , conducted by Project Recover from April 2018 through December 2019 , covered near to 27 square miles ( 70 square kilometers ) of the sea bottom in Truk Lagoon . Sonar scans distinguish possible airplane debris , which the scientists then investigated more closely by deploy divers and robots fit with high - definition camera . They bump debris fields with cadaver of the three aircraft at depths from 100 feet to 215 infantry ( 31 to 66 time ) , according to the statement .
Diving destination
Many of the liberal Japanese ships — rock oil tankers and merchandiser vessel measure hundreds of human foot long — that were fall off in Truk Lagoon in 1944 have since become overgrown with coral and are now democratic destinations for divers to inflict .
" The holds of some of these ship are really filled with Japanese airplanes and trucks , " said Colbourn . " These are awing places to go scuba diving . "
By comparison , airplanes that break-dance into fragments are n’t inevitably recognizable to unpaid divers , which could explicate why the miss planes — or what was leave alone of them — were overlook for so long , Colbourn explained .

As for the crewmen who were aboard the planes , there ’s " a high likelihood " that entire cadaver could be found inside the wreckage , particularly in the case of the TBM / F-1 Avenger numbfish bomber , in which two bunch members " were moderately much locked inside the back of the plane , " Colbourn say .
Now that the crash sites have been locate , archaeologically survey and mapped , Project Recover will turn its data over to the U.S. Department of Defense ’s Defense POW / MIA Accounting Agency , Colbourn explain . The federal agency will then evaluate the sites for the possible convalescence and designation of any clay .
" We wo n’t have a go at it until that recovery really hap , whether anyone is still inside the aircraft . But from our experience , I ’d say that there is a very good chance that that is the case , " Colbourn suppose .
