- Secondary-compilation registry record: AFDL-4, ex-USS AFD-4 (1943-1946), AFDL-1 class small auxiliary floating dry dock - laid down (date unknown) at Morgan City, LA by Chicago Bridge and Iron; delivered and commissioned USS AFD-4 in December 1943; decommissioned and placed in service (date unknown); redesignated AFDL-4 on 1 August 1946; placed out of service (date unknown); struck from the Naval Register (date unknown); transferred to Brazil in 1966, named Almirante Jeronimo Goncalves (G-26); current disposition 'active'. Awards: American Campaign Medal, World War II Victory Medal. Specs listed: displacement 800 t., length 200', beam 64', inside width 45', draft 3'3" light / 31'4" flooded, lifting capacity 1,900 tons. shipbuildinghistory.com corroborates: 'AFDL | 4 | | Chicago Bridge | Morgan City LA | 800 | 200 | Dec-43 | To Brazil 1966 as Almirante Jeronimo Goncalves (G 26), active'.

- Secondary compilations, not primary registry records - no NVR or DANFS entry located to confirm them (see negative-finding row). Core facts (builder, December 1943 delivery, 1946 redesignation, 1966 Brazil transfer, active status) are independently corroborated by the Brazilian NGB registry and Brazilian federal records. The '1,900 tons' lifting-capacity figure conflicts with the official BuSandA design value of 1,000 tons for 200-ft AFD docks - see correction row; 'date unknown' fields are explicit unknowns, not verified dates.

- Finding
- Official U.S. Navy construction history (Bureau of Yards and Docks, 'Building the Navy's Bases in World War II,' Ch. IX Floating Drydocks): the AFDs were '1,000-ton one-piece steel docks designed by the Bureau, intended for docking minesweepers, patrol craft, and similar vessels ... of the trough type, 200 feet long and 64 feet wide, with a clear width inside the wing walls of 45 feet, and a draft over the blocks of 14 1/2 feet ... entirely of welded steel construction ... fully self-contained, with diesel electric power plants, and contained limited repair facilities.' Construction was 'distributed among five contractors, using six different plants, of which three were on the East Coast, one on the Gulf Coast, one on the West Coast, and one on the upper Mississippi.' The 1946 nomenclature revision established AFDL as 'Auxiliary Floating Drydock Little' (under 10,000 tons) and 'the AFD's became AFDL's' - the blanket reclassification under which this hull became AFDL-4.

- Finding
- The official Navy logistics history appendix (Carter, 'Beans, Bullets, and Black Oil,' Dept. of the Navy 1953) lists commanding officers for AFD-type floating drydocks serving under Commander Service Force Pacific - AFD-3, AFD-9, AFD-13, AFD-14, AFD-15, AFD-17, AFD-18, AFD-19, AFD-20, AFD-21, AFD-25, AFD-26, AFD-27, AFD-28, AFD-29. AFD-4 does not appear - consistent with the hull's American Campaign Medal award and the absence of any Asiatic-Pacific ribbon in the NavSource awards block, indicating stateside/Atlantic WWII service rather than a Pacific advance-base assignment.

- A documented absence, not a station record: the appendix covers Pacific-theater service vessels, so non-appearance indicates only that the dock was not a Service Force Pacific asset - it does not prove where the hull served. The stateside/Atlantic inference is further supported by the awards block but remains inference, not a documented assignment. No deck log or station record for this hull was located.

Figures diverge from U.S. compilations (3,000 t loaded vs 800 t; 1,000 t vs 1,900 t capacity) - see correction row. Name 'Goiás' per NGB is carried as the 1966-1973 Brazilian name; U.S. compilations skip it and apply the later name retroactively.

- Finding type
- asbestos_application
- Finding
- Class/era inference only: the AFD design carried a diesel-electric power plant, ballast/pumping machinery, and limited repair facilities within a welded-steel trough dock delivered to the U.S. Navy in 1943. Diesel machinery and exhaust insulation, piping lagging, valve and flange gaskets, machinery packing, electrical insulation, accommodation insulating/decking materials, and winch/capstan brake linings of that era commonly contained asbestos. The dock's repair mission - docking and repairing minesweepers, patrol craft, and similar era vessels - placed its crew and repair shops alongside hulls whose own insulation commonly contained asbestos.

- Source discrepancies resolved or carried forward: (a) Lifting capacity - BuSandA official design value for 200-ft AFD docks is 1,000 tons (NGB 'capacidade para 1.000 toneladas' agrees); NavSource's 1,900-ton spec is the lengthened 288-ft dock figure displayed generically - 1,000 t adopted. (b) Displacement - U.S. compilations say 800 t; NGB says '3.000 ton (carregado)' - the Brazilian figure is on a loaded/ballasted basis; both carried attributed, unresolved. (c) Builder site - U.S. compilations say Chicago Bridge & Iron's Morgan City, LA plant; NGB says 'Chicago, Illinóis,' a probable conflation of company headquarters with fabrication site - Morgan City adopted pending primary contract records. (d) Brazilian name - U.S. compilations apply 'Almirante Jeronimo Goncalves' to the 1966 transfer; NGB documents the dock entered Brazilian service as Goiás and was renamed by Aviso Ministerial 0876 of 1973-09-20 - the dated NGB sequence adopted.
