- ShipScribe documents this hull within the five-ship Electron (AKS-27) conversion class: '(ex AG 150, ex LST 1102, comm 29 Jan 1945.) Reassigned to ComServPac effective 1 Jan 1946. Converted to mobile spare parts issue ship at Pearl Harbor Dec 1945 to Mar 1946. ICE & H & M spare parts issuing vessel at Tsingtao Jun 1947. Designated for inactivation 26 Aug 1947. Reported to Pacific Reserve Fleet, San Diego Group, 15 Nov 1947 for inactivation. Decommissioned in advance on 21 Nov 1947: 0% inactivated, not drydocked, not dehumidified, not packaged, and personnel transferred to SubGrp3. Placed OCIR 19 Mar 1948. To AG 150 and named 1 Feb 1949. Reactivation ordered 31 Aug 1950. Recommissioned 27 Dec 1950. To AKS 31 18 Aug 1951. Homeport shifted from Mare Island to Sasebo, Japan, late 1954. Scheduled for inactivation Oct 1957, on sale list Dec 1958. To buyer 2 Nov 1959.' Class notes: five early-1945 LSTs converted to mobile spare parts issue ships Dec 1945-Apr 1946 (sister entries for Electron and Proton specify 'NSY Pearl' as the conversion venue); reassigned to Commander Service Force Pacific effective 1 Jan 1946; CNO requested names 9 Dec 1948 after alterations changed characteristics to Spare Parts Issue Ships; island names approved 1 Feb 1949; all but Colington reactivated for Korean service Aug 1950; the five reclassified AG 146-150 to AKS 27-31 on 18 August 1951; 'PROTON and CHIMON were inspected in September 1957 while still active and found fit for future service. However subsequently they were stripped of their General Stores Issue facilities which were used for the modernization of POLLUX (AKS 4), resulting in seriously impairing their mobilization potential as AKS and in their early disposal.'

- Limitations
- Scholarly secondary compilation (Roberts) drawn from official registers - granular ship-level dates but not itself a primary registry page. Disposition table values for Chimon ('Decomm Oct 1957', 'Strike 1 Jan 1959', 'Disposal 9 Jul 1959') reflect scheduled/planned milestones and conflict with DANFS/NavSource actuals carried in this record (out of commission in reserve 22 Apr 1958; struck and sold 2 Nov 1959 - the ship note's own 'To buyer 2 Nov 1959' agrees). 'ICE & H & M' abbreviation not expanded in source. Sister-hull 'NSY Pearl' phrasing supports but does not flatly state a Naval Shipyard venue for Chimon's own conversion note ('at Pearl Harbor'). No asbestos content.

- asbestos_application
- Finding
- A diesel-powered LST-542-class hull built Nov 1944-Jan 1945 and twice refitted (1945-46 spare-parts conversion; 1950 reactivation) sits inside the Navy's documented asbestos-use era. Era-standard applications aboard a diesel LST/auxiliary of this period were engine-room and diesel-exhaust lagging, thermal insulation, gaskets, valve packing, deck coverings/tile, and bulkhead/accommodation insulation; the interior conversion to a spare-parts issue ship (added issuing spaces, stores handling) is the documented class-level pathway adding interior insulation scope on converted hulls. She carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

- Finding type
- litigation_documented
- Finding
- Documented occupational-disease litigation at this hull's builder during its exact construction window: the Indiana Court of Appeals affirmed an Industrial Board award denying compensation to the survivors of Elbert Woolsey, a pipe fitter employed by Missouri Valley Bridge & Iron Co. 'in the compartment of ships' from 21 June 1944 to 11 November 1944 (LST-1102 was laid down at the same Evansville yard 23 November 1944). The claim alleged fatal poisoning from inhaling fumes and gases of welded galvanized metal; the board found no occupational disease arising out of the employment and the award was affirmed.

Names the builder workforce and era only. Citation from official Indiana reports (119 Ind.

CourtListener opinion searches returned ZERO results for '"USS Chimon"' and '"LST-1102"' (type=o); a bare 'Chimon' opinion query completed with observed results being name collisions only; additional queries (docket type=r, AG-150/AKS-31, Woolsey lookup, 'Chimon' re-enumeration) were blocked by the shared fleet pacing budget - logged honestly in search_ledger, not claimed as negative results. Secondary web sweeps surfaced only law-firm marketing content (mesotheliomasymptoms.com lists 'USS Chimon (AG-150)' asserting asbestos aboard without primary sourcing - excluded by source policy).

- CORRECTIONS: (1) AKS-31 reclassification date - NavSource, NavalCoverMuseum, and Wikipedia carry '27 December 1950' (a conflation with her recommissioning date); DANFS and ShipScribe's official-register-derived data both give 18 August 1951, when the whole AG 146-150 group became AKS 27-31 - the 18 August 1951 date is carried. (2) Class designation - Wikipedia labels her 'LST-511-class'; the authoritative per-hull reference (NavSource) labels her LST-542-class and her hull number sits in the BuShips LST1081-1152 design group of the LST-542 series; the DANFS spec block's 'cl. LST-1' is the umbrella series label. (3) Builder shorthand - NavSource/Wikipedia 'Missouri Bridge and Iron Works' vs documented 'Missouri Valley Bridge and Iron Works' (DANFS; ShipScribe 'Missouri Valley Bridge').
