- DANFS record for this hull (spec block: dp. 1,400; l. 306'; b. 36'10"; dr. 9'5"; s. 24 k.; cpl. 186; a. 3 3", 3 21" tt, 2 dct., 8 dcp., 1 dcp. (h.h.); cl. Buckley). Namesake: Lt. Comdr. Hubert Montgomery Hayter (b. Abingdon, Va., 17 Oct 1901; USNA 1924; Arizona, Yarborough; CO Ramsay (DM-16) 1939; New Orleans 5 Feb 1941; killed off Savo Island 30 Nov 1942 as damage control officer; Navy Cross posthumous). Hayter (DE-212) launched 11 November 1943 by Charleston Navy Yard, Charleston, S.C.; sponsored by Mrs. Maurine K. Hayter, widow; commissioned 16 March 1944, Lt. Comdr. Harold H. Theriault in command. Departed Charleston 7 April 1944 for Bermuda shakedown; escort division Atlantic duty; three convoy voyages to Bizerte 1 June-30 November 1944 (two from Norfolk, one from Casco, Maine), including division-doctor transfers at sea. December 1944 in Boston Navy Yard. Sailed 2 January 1945 with Escort Division 62 hunting U-248; HF/DF fix 0647 16 January; Hayter sound contact 0908; five depth-charge patterns over two hours (two by Hayter); debris surfaced; returned Norfolk 5 February 1945. Casco Bay departure 17 March; sweeps southeast of Newfoundland; Argentia 14 April; barrier patrol between escort carriers Bogue and Core; on 24 April Frederick C. Davis (DE-136) was torpedoed by U-546 and Hayter rescued 65 survivors and recovered 12 of 126 dead. Arrived Argentia 6 May; sailed 8 May for Philadelphia Navy Yard via Boston, arriving 22 May; conversion to high speed transport; designation became APD-80 on 1 June 1945. Departed Philadelphia 13 August 1945 for Guantanamo refresher training; Norfolk/Newport operations to 30 October; Green Cove Springs Reserve Fleet; decommissioned 19 March 1946; moved to Texas group; struck 1 December 1966.

- Limitations
- DANFS documents namesake, construction, service chronology, conversion yard, and striking - not materials or asbestos content. DANFS does not print a keel-laying date (11 August 1943 carried from NVR/NavSource); the namesake's flagship detail (New Orleans CA-32) is the named-uncle biography, not this hull's record. Mirror citation because the live NHHC page returns 404. First-CO name conflicts with NavSource's 'Harold John Theriault' - logged in gaps.

- Limitations
- Official register data: all carried dates/dimensions agree with DANFS where both print them (commission, launch, decommission, stricken - no conflicts). The NVR 'date status changed' field is blank in the 2024 capture, so the 1967 transfer lacks an official day-date here; NavSource's 23 July 1967 is secondary. NVR documents dates/dimensions/status, not materials or asbestos content; the SAP-status line confirms the Korea transfer path without further detail.

- Finding
- Era/design inference: this hull is a 1943 Charleston-built Buckley-class (TE) destroyer escort with a full steam plant - BuShips Ships' Data 1945 design groups 2-3 document the type at 2 'D' express-type boilers (435 psi/750 F superheat) feeding GE turbine-generators/electric motors, 12,000 shp, 2 shafts; NavSource's APD-80 spec block reads 2 Combustion Engineering 'D' Express boilers and the navypedia block map assigns Combustion Engineering to the DE-199-213 block including DE-212 (both secondary). Steam escorts of the 1942-43 DE program carried era-standard asbestos in boiler and machinery insulation, steam-line lagging, valve and flange gaskets, machinery packing, electrical insulation, deck coverings, and brake linings; the 1945 APD conversion added troop berthing/messing and four LCVP davits (work that disturbs existing insulation and adds new lagging/coverings).

- Finding
- Yard-level context for the two Navy yards tied to this hull: builder Charleston Naval Shipyard is a tier-2 yard in the Atlas dataset (documented asbestos-product list incl. pipe insulation 5-50% asbestos, boiler coatings 15% asbestos, spray-on insulation, gaskets/packing; yard-level litigation incl. Whalen v. John Crane 2014 and Twidwell v. Aerco 2018; OSHA 1988 inspection 100361849 with an asbestos-standard citation). The May-August 1945 conversion at Philadelphia Naval Shipyard is documented by DANFS ('arrived 22 May and began her conversion to high speed transport') - that yard is tier-3 in the dataset with named product identification in published appellate opinions (Taylor v. Celotex 1990; Junge v. Garlock 1993; Gross v. Johns-Manville 1991) and an OSHA 1989 health inspection (17999079) listing citations under 29 CFR 1910.1001 with a 90-percent bulk asbestos sample.

- GAO HRD-80-2 (Oct 1979); class file ev-buckley-class-06
- Finding type

- Finding
- GAO documented that the Navy's standing asbestos-removal policy dates from 1975 (remove asbestos insulation only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas). This hull left U.S. custody by SAP/MAP transfer to Korea in 1967 - before any standing Navy asbestos-control program and before disposal hazmat documentation practices - so the hull is consistent with era materials retained in place through its U.S. service life and transfer; no U.S.-custody abatement or disposal material record is expected to exist.

- Completed sweeps: type=o '"USS Hayter"' returned 0 results; type=o '"Hayter"' returned 980 results whose reviewed top hits are all personal-name collisions (Hayter v. Hayter, Hayter v.

Pending sweeps: asbestos-qualified 'Hayter' opinion query, type=r docket sweep for 'USS Hayter', and hull-number sweeps '"DE-212"' / '"APD-80"' remained fleet-paced at drafting time (shared token-bucket budget ~114/hr across all sessions repeatedly exhausted). Open-web sweep located law-firm marketing pages naming USS Hayter (asbestos-ships.com dedicated hull page; mesotheliomahelp.org and simmonsfirm.com boilerplate at-risk-ships lists) - banned source types, logged as excluded hits in the search ledger, carrying no evidence value.

- No qualifying ship-specific asbestos record located for DE-212/APD-80: no asbestos survey, abatement contract, disposal hazmat disclosure, museum documentation, or docketed asbestos case naming the vessel was found in the public sources searched (see search_ledger). The hull transferred to the Republic of Korea in 1967 - before the Navy's documented asbestos-control program era (GAO HRD-80-2: standing removal policy dates from 1975) and before disposal hazmat documentation practices - so no U.S.-custody abatement or disposal-phase material record is expected to exist; the 1986 ROK target expending is undocumented in the sources searched.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 steam-plant hull is consistent with retained era materials through its U.S. service life and foreign transfer. Does not establish that asbestos is or is not present; does not establish or defeat any claim of exposure or legal eligibility. The CourtListener coverage is partial (one verified no-result opinion sweep plus a collision-dominated name sweep; hull-number and docket sweeps pending at drafting) - if completed hits surface later this finding is revisable.
