About this Unit
**AFDL-6** is a U.S. Navy auxiliary floating dry dock launched in 1943 during World War II. Originally designated as YFD-62, it was later reclassified as AFDL-6 (Auxiliary Floating Dry Dock, Light). Throughout its service, AFDL-6 provided essential repair and maintenance support to naval vessels, especially in forward areas where shore-based facilities were unavailable. The unit contributed significantly to fleet readiness during both World War II and the Cold War before being placed in reserve status.

• Origin of the Name: AFDL-6 stands for "Auxiliary Floating Drydock, Light - 6," part of a class of small drydocks used by the U.S. Navy primarily during World War II and the Cold War era.
• World War II Service: AFDL-6 was constructed in 1943 to support naval operations by providing mobile repair facilities in forward areas, making it possible to conduct essential maintenance away from established shipyards.
• Constructed by Chicago Bridge & Iron: The drydock was built by the Chicago Bridge & Iron Company, a major producer of floating drydocks and other military infrastructure during WWII.
• Pacific Theater Deployments: During WWII, AFDL-6 served in the Pacific, where it repaired a variety of vessels including patrol craft, landing craft, and smaller warships damaged in combat or by the harsh sea environment.
• Modular Design: The AFDL-6 was designed in sections for easy assembly and transportation, allowing it to be shipped in pieces and reconstructed at remote locations.
• Postwar Service: After WWII, AFDL-6 continued to serve the U.S. Navy, being stationed at various naval bases and providing maintenance support during the Korean War and into the Cold War.
• Renamed and Redesignated: In 1968, AFDL-6 was renamed Endurance, continuing the Navy tradition of bestowing names upon previously numbered auxiliary vessels.
• Support for Submarine Operations: At different times, AFDL-6 supported submarine squadrons, providing critical maintenance to submarines that could not return to major shipyards for repairs.
• Decommissioning: AFDL-6 was eventually decommissioned and struck from the Naval Vessel Register, but some AFDL-class docks have been transferred to allied navies or used for civilian purposes.
• Legacy: The story of AFDL-6 highlights the unsung but vital role of auxiliary and support vessels in military operations, enabling front-line ships to remain in action far from home ports.
