This photo of USS Thresher (SSN-593) underway on the surface is our photo for this week in .

Tomorrow will mark 63 years since Thresher's tragic end; on April 10, 1963 Thresher was doing deep-diving tests, along with USS Skylark (ASR-20), off the coast of Massachusetts. As the tests proceeded, Skylark received garbled communications from her which eventually stopped - Thresher had sunk, claiming the lives of the 129 officers, crewmen, and civilian technicians.

The loss of Thresher eventually pushed the U.S. Navy to establish a quality assurance initiative two months later known as the Submarine Safety Program (SUBSAFE) which remains in use today.

Since is on April 11, we've decided to make April our unofficial . This is a by Georges Schreiber titled, "Conning Tower, USS Mackerel" is our chosen piece of for this .

There is no surcease in the vigilance aboard a submarine. Vulnerable to depth charges and bombs, eternally a "lone wolf" on a mission, the submarine must be ready to crash-dive at an instant's notice. The skipper and executive of "old 204" augment the regular lookouts on the conning tower between submerging.

🚨📰 UPDATE: USS John P. Murtha to support NASA's Artemis II mission

SAN DIEGO – Amphibious transport dock ship USS John P. Murtha (LPD 26) is slated to serve as the recovery ship for the Orion spacecraft and its crew upon their return from the historic Artemis II mission.

The Artemis II mission is the first crewed flight of NASA's Space Launch System (SLS) rocket and Orion spacecraft, sending four astronauts on an approximately 10-day journey that will take them beyond the Moon. This mission will mark humanity's first crewed voyage to the vicinity of the Moon in over 50 years.

Upon completion of their mission, the Orion capsule will splash down in the Pacific Ocean, where John P. Murtha and its crew will be prepared to recover the astronauts and the spacecraft.

Today, we pause to remember the USS Thresher (SSN-593), which was lost at sea on April 10, 1963, during deep-diving trials off the coast of Cape Cod, Massachusetts. All 129 souls aboard, including 112 U.S. Navy personnel and 17 civilian technicians, were lost in the tragedy.

The Thresher was the lead boat of a new, advanced class of nuclear-powered attack submarines. At the time, her loss was the world's deadliest submarine disaster and marked the first time a nuclear-powered submarine had been lost at sea.

In the wake of this tragedy, the U.S. Navy established the Submarine Safety (SUBSAFE) program. This rigorous quality assurance and safety initiative has been instrumental in protecting the lives of submariners, and since its implementation, no SUBSAFE-certified submarine has been lost.

Though built at Portsmouth Naval Shipyard, the loss of the Thresher was a profound event felt across the entire naval shipbuilding community. Today, Norfolk Naval Shipyard joins in honoring the memory of the brave crew and civilians who were lost. Their sacrifice led to a legacy of safety that continues to protect sailors today.

We remember the crew of the USS Thresher, who are on eternal patrol.
