Underwater archaeologists have found the wreck of the USS Albacore off the Japanese coast.

USS Albacore (SS-218) was a Gato-class submarine, which served in the Pacific Theatre of Operations until she was lost at sea in 1944.

Albacore′s keel was laid on 21 April 1941 by the Electric Boat Company in Groton, Connecticut. She was launched on 17 February 1942, sponsored by Mrs. Elise Riles Cutts, and commissioned on 1 June 1942.

During her two years of active service, the USS Albacore was awarded the Presidential Unit Citation and nine battle stars.

On the 24th October, 1944, the Albacore left Pearl Harbor to patrol the Japanese coast. After loosing all contact with the submarine, the Albacore was presume lost with all hands and was stricken from the Naval Vessel Register.

According to Japanese naval records, a submarine (presumed to be the Albacore) exploded after it struck a mine of the shores of Hokkaidō on 7 November 1944.

A sonar survey of the area in 2022 by Dr. Tamaki Ura of the University of Tokyo, detected what appeared to be a submarine hull 7 kilometres east of Hakodate. A remotely operated underwater vehicle to photographic and video evidence of the wreck site, which were sent to the Naval History and Heritage Command at the historic Washington Navy Yard for identification.

In a recently issued press release, the Naval History and Heritage Command has confirmed that the submarine is indeed the USS Albacore, based on several key features of a late 1944 Gato-class submarine, including documented modifications of the SJ Radar dish and mast, a row of vent holes along the top of the superstructure, and the absence of steel plates along the upper edge of the fairwater.

“As the final resting place for Sailors who gave their life in defense of our nation, we sincerely thank and congratulate Dr. Ura and his team for their efforts in locating the wreck of Albacore,” said NHHC Director Samuel J. Cox, U.S. Navy rear admiral (retired). “It is through their hard work and continued collaboration that we could confirm Albacore’s identity after being lost at sea for over 70 years.”

New chambers discovered in Ancient Egyptian pyramid of Sahura

Published

By

An Egyptian-German archaeological mission has discovered several new chambers in the pyramid of Sahura, located in the Abu Sir Pyramid Field south of Giza.

Sahura, meaning “He who is close to Re”, was a pharaoh of Ancient Egypt and the second ruler of the Fifth Dynasty (2465 BC to 2325 BC). Sahure’s reign is seen as one of economic and cultural prosperity, opening new trading links to the land of Punt and expanding the flow of goods from the Levantine coast.

Choosing not to follow the tradition of being buried in the royal necropolises of Saqqara and Giza, Sahura instead chose for his pyramid to be constructed at Abusir. Although smaller in size than the pyramids of his predecessors, Sahura’s pyramid complex was decorated with over 10,000 m2 of finely carved reliefs, some of which are considered “unparalleled in Egyptian art.”

The interior chambers of the pyramid were extensively damaged by grave robbers during antiquity, making it impossible to precisely reconstruct the substructure plan.

A restoration project led by Egyptologist Dr. Mohamed Ismail Khaled of the Department of Egyptology at Julius-Maximilians-Universität of Würzburg (JMU) has discovered a series of storage chambers and passageways. The northern and southern parts of these chambers are badly damaged, however, remnants of the original walls and parts of the floor can still be seen.

Using 3D laser scanning with a ZEB Horizon portable LiDAR scanner, the team conducted detailed surveys to map the extensive external areas and the narrow corridors and chambers inside.

According to the researchers: “Careful documentation of the floor plan and dimensions of each storage chamber has greatly enhanced our understanding of the pyramid’s interior. During restoration, a balance between preservation and presentation was pursued to ensure the structural integrity of the chambers while making them accessible for future study and potentially the public.”

During the restoration work, the project was also able to uncover the floor plan of the antechamber which had deteriorated over time. Consequently, the destroyed walls were replaced with new retaining walls. The eastern wall of the antechamber was badly damaged, and only the northeast corner and about 30 centimetres of the eastern wall were still visible.

Archaeologists identify runesmith who carved the Jelling Stone runes

Published

Archaeologists using 3D scans have identified who carved the Jelling Stone runes, located in the town of Jelling, Denmark.

The first of the two Jelling stones was erected by King Gorm the Old in honour of his wife Thyra. Following this, a second stone was raised by King Gorm’s son, Harald Bluetooth, to commemorate his parents and to mark his victorious rule over Denmark and Norway, as well as his role in converting the Danish people to Christianity.

Researchers from the National Museum in Copenhagen have conducted 3D scans to analyse the carving tracks of the runes. Similar to handwriting, the carving techniques are relatively unique to each runesmith, as each stonemason holds the chisel at a certain angle and strikes with a certain force with the hammer.

By studying the angle of the chisel grooves and the distance between them, comparisons can be made with other rune stones, such as the Laeborg Runestone which stands approximately 30 kilometres southwest of Jelling

The analysis has revealed that the Laeborg Runestone has the same carving technique, which also has the inscription: “Ravnunge-Tue carved these runes after Thyra, his queen”.

Queen Thyra is mentioned in the two Jelling stones as the mother of Harald Bluetooth, wife of Gorm the Elder and “penitent of Denmark”, but Thyra’s name is also mentioned in two other runestones, that of Læborg, carved by Ravnunge-Tue in honor of Thyra, his queen, and that of Bække 1, which bears the inscription “Ravnunge-Tue and Fundin and Gnyple, the three made the stop of Thyra.”

For many years, researchers have debated whether Læborgstenen’s Queen Thyra is the same as the Thyra mentioned on the stones from Jelling.

According to the researchers: “The discovery in itself is interesting because it can link another person to the Jelling dynasty, but it is especially interesting because the realization brings with it another startling revelation, explains Lisbeth Imer, runologist and senior researcher at the National Museum.”

“It is an absolutely incredible discovery that we now know the name of the rune maker behind the Jelling stone, but what makes the discovery even wilder is that we know Ravnunge-Tue’s boss. It is Queen Thyra from Jelling, i.e. Harald Blåtand’s mother, there can no longer be much doubt about that, and that puts the discovery in a completely different light,” says Lisbeth Imer.
