- Documented for this hull: 'originally projected as the tank landing ship LST-1111 but redesignated a stores issue ship before construction began,' laid down 2 January 1945 at Evansville, Ind., by the Missouri Valley Bridge & Iron Co.; 'reclassified a self-propelled barracks ship and redesignated APB-45 on 6 March 1945'; launched 9 April 1945, sponsored by Mrs. Henry E. Russell; commissioned at New Orleans, La., 9 June 1945, Lt. A. E. Lorance, USNR, in command. Spec block: dp. 4,080 (lim.); l. 328'0"; b. 50'0"; dr. 11'2" (lim.); s. 10 k.

Lorance Jr. USNR in command; assigned to the Asiatic-Pacific Theater; Navy Occupation service in the Far East 5-30 October 1945; decommissioned 26 April 1947 at Orange, TX; laid up in the Atlantic Reserve Fleet, Texas Group, Orange; struck from the Naval Register 1 April 1960; 'Sold for commercial service to Collins Submarine Pipeline(Marine Diamond) in 1963, apparently not scrapped as reported by DANFS'; final disposition 'sunk as a target by the South African Navy circa 1968-70.' Contributor photo captions (Jim Moore) document the ex-hull moored pierside at Beaumont, TX, in 1963 after withdrawal from the Orange reserve fleet and tow to Beaumont for reactivation and drydocking, and drydocked there during the retrofit: 'Renamed APB-45, she was used for dredging operations in the mining of diamonds off the south-west coast of Africa until approximately 1968-70 at which time she was donated to the South African military and was used for bombing practice and ultimately sank.' Awards documented: American Campaign Medal, Asiatic-Pacific Campaign Medal, WWII Victory Medal, Navy Occupation Service Medal (Asia clasp), Philippines Liberation Medal. CO list: LT Lorance (9 Jun 1945-28 Sep 1945), LT E. W. Mauthe (to 20 Jan 1946), LT D. F. Burns (to 10 Aug 1946), CHBOSN J. E. Hammond (to 1 Feb 1947). Specifications: 4,000 t; 328' length; 50' beam; 11'2" draft; 12 kts; two GM 12-567A diesels, single Falk main reduction gear, two propellers 1,600 shp, five 100 kW diesel-driven ship's-service generators; complement 12 officers/125 enlisted plus 28 officers/275 enlisted troop accommodation; armament two quad 40mm AA mounts and twenty .50/.30 cal machine guns.

- Limitations
- NavSource is a volunteer secondary compilation; USN milestone dates track DANFS/NVR, but post-Navy facts rest on contributor photo captions - the photographs document the hull afloat and in refit at Beaumont in 1963 and describe its subsequent commercial service and sinking, which contradicts the DANFS 'scrapped 1960' disposition (see ev-uss-blackford-lst1111-07). Contains no asbestos content.

Ship note: 'Ex AKS-16 31 Mar 45, ex LST-1111 14 Dec 44. Converted by builder. In reduced commission 1-9 Jun 45 for transit to New Orleans. In USN reserve 1946-60.' Class notes document the conversion program: in August 1944 the Commander, Amphibious Forces, Pacific Fleet began developing specifications to convert four LSTs under construction into 'mother ships' for YMS, PC, PCS, SC, LCI, and LCT types; the hulls were reclassified Stores Issue Ships (AKS) in December 1944 before being laid down, then reclassified APB while still on the ways when the AKS designation failed to cover the mother-ship role; accommodations for around 300 men in addition to ship's company were installed in a new deckhouse extending from the stern to near the bow, with 5-ton booms for resupplying other ships; late in the design the pilot house was moved forward to the front end of the new deckhouse.

- Peer-reviewed industry history documenting the commercial operator that NavSource's photographic record attaches to this hull: Sam Collins's Marine Diamond Corporation recovered the first officially recorded seabed diamonds on 15 November 1961 near Luderitz; after the loss of Barge 77 in a June 1963 storm, 'a tank landing craft vessel was quickly converted into the diamond recovery vessel Diamantkus'; Diamantkus, Barge 111, and Colpontoon were withdrawn in 1967; MDC mined roughly 1.5 million carats between 1961 and 1970 before De Beers participation.

- Finding
- Era and design inference for this hull: the underlying vessel is an LST-series hull (BuShips SD-1945 design grouping; ~328 ft oa, 50 ft beam, ~2,366 t light / ~4,080 t limiting) powered by two General Motors 12-567A diesels (~1,600-1,800 shp) through Falk reduction gears on two shafts - a diesel plant with NO boilers, so the boiler/turbine steam-lagging pathway does not apply. The builder's APB conversion added a deckhouse with accommodations for ~300 men (shipscribe class notes). Era-standard applications aboard a 1945 diesel auxiliary hull of this type: engine-room and diesel-exhaust lagging, machinery gaskets and valve packing, deck coverings, and accommodation insulation; the wartime shipbuilding program reserved asbestos supply and used asbestos insulation extensively aboard naval vessels through the period (see ev-uss-blackford-lst1111-06).

- Finding
- CORRECTION: DANFS records 'sold to the Sampson Iron Supply Co. on 3 August 1960 for scrapping,' and shipscribe's disposition table records 3 Aug 60 'Sold.' NavSource's photographic record contradicts the scrapping outcome: contributor photographs show the ex-hull afloat at Beaumont, TX, in 1963 after tow from the Orange reserve fleet, and drydocked during a documented retrofit for Collins Submarine Pipeline (Marine Diamond); captions state she was renamed 'APB-45,' used for diamond-dredging operations off the south-west coast of Africa until approximately 1968-70, then donated to the South African military and sunk as a target. The 1960 sale and 1963 commercial service are not necessarily inconsistent (the scrap buyer may have resold the hull), but 'scrapped in 1960' is photographically falsified.

CourtListener opinion index verified zero hits for all four designations (type=o, count 0, 2026-10-02), and a 'Blackford'+asbestos opinion query returned only unrelated name/term collisions. Docket-level (type=r) coverage was blocked by the fleet-wide request budget - litigation status: no qualifying opinion located, docket coverage incomplete. Secondary web sweeps surfaced only a surname collision (an individual plaintiff named Blackford) and law-firm marketing listicles - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the 1945 build and the 1963 commercial refit sit inside the era of documented shipboard asbestos use. Undigitized leads remain: NARA RG 24 deck logs and ship's muster rolls, builder contract records (Missouri Valley Bridge & Iron), and any 1963 Beaumont refit specification. Does not establish or defeat any claim of exposure or legal eligibility.
