- The Chilean Navy's official unit history identifies this hull by its former name 'USS LSM 113' and documents: purchased from the United States under contract No. 142 Chile 10 dated 12 January 1947; arrived in Chile 14 June 1947; assigned by Decreto Supremo No. 1.167 of 25 August 1961 to the Empresa Maritima del Estado (state shipping corporation) for ten renewable years and delivered to it 27 November 1961; subsequently returned to the Navy and decommissioned ('dada de baja') by Decreto Supremo No. 229 of 23 February 1970; alienated ('enajeno') under Ley No. 14.564 for 5.448,40 escudos to Ignacio Munita Silva. Listed characteristics: year 1944; displacement 1,095 t full load / 743 t standard; machinery 2,800 BHP; armament four 20 mm machine guns; maximum speed 12 knots.

- Finding
- The Brown Shipbuilding yard list carries this hull as yard hull number 218, LSM 113: keel laid 14-Oct-44, launched 4-Nov-44, delivered 30-Nov-44, disposition 'To Chile 1947 as Contreras, scrapped 1967.' Yard history on the same page: Brown Shipbuilding was built in 1941 by George and Herman Brown at the junction of Green's Bayou and the Houston Ship Channel with $9 million in Navy funding; it built 12 PCs, 32 LCI(L)s, 61 DEs and 254 LSMs - 359 vessels in four years; in 1949 the yard was leased to Todd Shipyards Corporation, which operated it as its Houston Division until 1984.

- Finding type

- Finding
- The class manual documents the machinery plant this hull was built to: Chapter 30 - each LSM is powered by two main propelling diesel engines; Fairbanks Morse Model 38D8-1/8 (ten-cylinder opposed-piston, direct drive, hydraulic coupling, one wet-type muffler per engine) is fitted on hulls Nos. 1-125 (which includes LSM-113), 126-141, 201-232, 253-269, and 310-331, while General Motors Model 16-278-A is used on the remainder. Chapter 31-9 - every vessel carries an auxiliary steam boiler: oil-fired water- or fire-tube type supplying 1,500 lb/hr saturated steam at 35 psig (designed for at least 50 psig), located in boiler room compartment C-101-1/2E on the Main Deck starboard side between frames 24 and 26. Chapter 1 - complement listed as 4 officers + 48 enlisted ship's crew and 2 officers + 52 enlisted troops; designed displacement 513 t light / 734 t landing / 912 t full load. Chapter 32 (pumps, tanks, piping systems) contains no insulation, lagging, or asbestos terms.

[6]Era inference built on: LSM Class Manual (ev-04 - diesel propulsion with one oil-fired auxiliary steam boiler per vessel); NavSource specifications from Ships' Data Vol. III (Fairbanks Morse diesels); GAO HRD-80-2 Navy asbestos-era documentation (ev-05) [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-propelled amphibious landing ship built October-November 1944 sits inside the Navy's documented asbestos-use era. The asbestos-relevant systems aboard an LSM-1-class vessel were the oil-fired auxiliary steam boiler and its steam piping (insulation/lagging), diesel-engine exhaust lagging and muffler insulation, machinery-space thermal insulation, gaskets, valve packing, and electrical insulation - not the boiler/turbine main-plant lagging of a steam ship, since propulsion was diesel. The landing-ship confined-volume and wartime-rapid-construction dynamic applies to the build era.

- Class/era inference only - no hull-specific insulation survey, material list, or work package located for LSM-113. Names era-standard applications, not confirmed installed materials. No quantity. Product names are normalized era terms; no manufacturer attribution for this hull. The auxiliary boiler aboard the class makes steam-system insulation a genuine class pathway, unlike pure-diesel types with no steam plant.

- Finding type
- gov_survey
- Finding
- GAO documented Navy asbestos exposure-control efforts and reviewed the use of asbestos in Navy ships, the cost of removing asbestos from Navy ships, and compensation programs - covering the era in which this hull was built (1944). The Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for repairs; in 1979 it was modified to selectively replace asbestos insulation in high-maintenance areas.

[8]Harry S. Truman Library Institute, 'Navy Day 1945' photo exhibit (official presidential-library institution page) - Navy Day October 27, 1945, with more than 150 ships berthed at 56 ports; NavSource photo caption for LSM-113 at Davenport, Iowa, 28 October 1945 [other_primary]

- Finding type
- historical_record
- Finding
- A NavSource photograph documents this hull moored pierside at Davenport, Iowa, on 28 October 1945 - the day after Navy Day 1945 (27 October), for which the Truman Library documents that more than 150 Navy ships were berthed at 56 ports across the States and Territories for the victory celebration. An upriver Mississippi presence at Davenport on that date is consistent with the Navy Day dispersal of ships to inland ports.

- Limitations
- The linkage to Navy Day is circumstantial: the photo establishes presence at Davenport on 28 Oct 1945, and the Truman page establishes the fleet dispersal to 56 ports on 27 Oct 1945, but no document located names LSM-113 as an official Navy Day participant. No asbestos content.

[9]Designation/disposal cross-check: Armada de Chile official unit history (ev-02) vs NavSource 10/14/14113.htm, uboat.net ship/12724.html, and navalmarinearchive.com LSM disposition table [other_primary]

- historical_record
- Finding
- CORRECTION: secondary compilations carry Chilean-era disposal dates that conflict with the Chilean Navy's official unit history. NavSource and navalmarinearchive.com state 'decommissioned by Chilean Navy 1959' and 'hulk cannibalized for spare parts and scrapped 1967'; the Armada de Chile record instead documents assignment to the state shipping corporation Empresa Maritima del Estado in 1961, formal decommissioning (baja) by Decreto Supremo No. 229 of 23 February 1970, and sale under Ley No. 14.564 to Ignacio Munita Silva. Separately, uboat.net carries a U.S. decommissioning date of 17 March 1947 vs NavSource's 20 March 1947, and uboat.net carries an order date of 15 September 1943 that NavSource does not display. The Chilean official record carries decree and law numbers and is treated as controlling for the Chilean milestones.

The official Chilean record does not itself state a scrapping date or location after the 1970 sale - 'scrapped 1967' cannot be reconciled with a 1970 sale and is rejected, but the hull's actual breakup date/place is undocumented (see gaps).
