    M.H. de Young laid down under Maritime Commission contract (MCE hull 1587) 1943-06-15 at Richmond, CA by Permanente Metals Corp.; launched 1943-07-06, sponsored by Mrs. George T. Cameron; delivered to the Maritime Commission 1943-07-19. Operated under a Maritime Commission charter (DANFS names 'American Presidential Lines' - see limitations). Torpedoed by Japanese submarine I-19 on 1943-08-14 about 1,000 miles east of Noumea, New Caledonia; brought into Espiritu Santo, New Hebrides, partially repaired, and taken over by the Navy under bareboat charter 1943-10-04. Renamed Antelope (IX-109) and placed in service the same day, Lt. L.G. Elsell in charge. Engines removed; spent the entire war as a non-self-propelled dry cargo storage vessel assigned to Service Squadron 9 - Espiritu Santo first duty station, possibly Leyte, Subic Bay last known location. Inspected at Subic Bay, found beyond economical repair; placed out of service 1946-05-03 and delivered to the Maritime Commission's War Shipping Administration; struck 1946-05-21; sold for scrapping to Asia Development Corp. 1948-03-03.

    DANFS is an official compiled history; the entry itself notes 'scanty records make it impossible to compile a list of locations.' Its 'American Presidential Lines' operator line conflicts with the vessel's primary status card and USCG report, which show R.A. Nicol & Co., Inc. as WSA general agent - carried as Nicol per the primary document. Entry contains no asbestos, materials, or casualty-detail information. Wikipedia's rendering of this same entry says Service Squadron 8 where DANFS says 9 - DANFS carried.

    Master's casualty report: S/S M.H. De Young (O.N. 243893), owner WSA, operator R.A. Nicol & Co., ocean freight service, voyage Port Hueneme, CA to Espiritu Santo, New Hebrides, cargo 3,900 tons general (including Seabee barge pontoons stowed in every hold - noted as nearly making the ship unsinkable). Torpedoed 1943-08-13 at 1950 at position 21-50 S, 175-10 W; one torpedo hit, extensive damage to machinery; submarine sighted after the attack; SOS sent; ship armed and armament used with unknown result. 95 aboard (42 merchant crew incl. master W. Munda; 25 Armed Guard - 1 officer, 24 enlisted; 28 passengers). Casualties: 4 lost (1 officer, 2 unlicensed crew - the 3-man engineering watch below - and 1 passenger) by shell or torpedo fire; 6 injured. Master ordered all except himself, 2 merchant crew, and the armed guard to abandon ship into lifeboats; crew and passengers reboarded next morning; ship towed in to Espiritu Santo.

    Handwritten standard USCG casualty form; a few entries are partially legible. The report dates the attack 1943-08-13 1950 while DANFS gives 1943-08-14 - likely a local-date vs. zone-date difference at 175W, logged as a discrepancy rather than resolved. Master reported to the Eleventh Naval District 14 months after the event. No materials or asbestos content.

    Finding
    The USMC operating manual for the EC2-S-C1 plant describes cylinder insulation of magnesia under sheet-iron lagging; insulation products of this era were commonly manufactured with asbestos fiber, and period steam-system gaskets, packing, and insulation felts commonly contained asbestos. This hull was built to that standard in mid-1943 at a Kaiser emergency yard.

    Limitations
    Design/class documentation, not a hull record - the manual does not name this vessel and does not itself state 'asbestos' content. Hull-specific counterweight: the Navy removed her engines in late 1943 after torpedo damage to machinery spaces, so at least some machinery-space material load was disturbed or removed; what remained in accommodation and auxiliary systems is undocumented. Asbestos presence aboard this hull is era inference, not ship-proven; does not establish quantity or any individual exposure.

The hull's 1943-46 Navy career was as a stripped, non-self-propelled storage hulk, and the hull was scrapped in China ~1950 - before the asbestos-regulatory era - so no modern survey record can be expected.
