- Finding
- Ship-specific wartime record: in June 1942 PE-27 was 'assigned to the East Coast Sound School at Key West, Florida,' LCDR Harold C. Speed USNR (46) in command. After U-157 sank the tanker Hagan off northern Cuba on 11 June 1942, PE-27 joined the search with AAF B-18s, USCG cutters Thetis and Triton, and three submarine chasers. On 13 June, after Triton's depth-charge attack on a contact, PE-27 'stood in,' broke off a first run, and at 1822 on a second run dropped three 300-lb depth charges - the charge cases sticking in their tracks from excess welding - observing 'oil slick and air bubbles [rising] to the surface in increasing intensity'; Thetis recovered debris. The Navy credited Triton with the kill. Class employment context: by 1 January 1921 fifteen Eagles lay in ordinary at Portsmouth NH Navy Yard and three were in active commission; the rest trained reservists across seven naval districts or served at air stations, as submarine tenders, at the Washington Navy Yard, and at the Naval Academy. In 1940 the surviving Eagles were earmarked for local defense: PE-38 reduced commission 31 May 1940 Puget Sound; PE-19 17 June Boston; 'later in 1940 the Eagle 27 (PE-27) went into reduced commission at Boston.'

- A documented commanding officer of this hull (1937-1939, per NavSource) was subsequently lost in service: LT James Stroud Clarkson, USN, died 9 February 1942 aboard USS Nevada (BB-36) - 'overcome by gas in a compartment in which he was working' and fallen into about two feet of water during Pearl Harbor salvage operations; Chief Machinist's Mate DeVries also perished attempting the rescue. Clarkson's posthumous Navy and Marine Corps Medal citation: 'for heroic conduct as a volunteer diver engaged in Pearl Harbor salvage operations... unhesitatingly made many hazardous dives in essential underwater work.' (Date-of-death discrepancy: headstone 9 February vs other references 7 February - noted on the memorial page.)

- Finding
- A 1918-19 steel steam patrol craft: two 250-psi water-tube boilers feeding a geared steam turbine on one shaft - the standard asbestos-relevant architecture of the era's small steam combatants. Era-standard applications aboard a vessel of this type and period were boiler lagging and brickwork-adjacent refractory materials, steam-line and turbine insulation, flange and valve gaskets, valve-stem packing, and related thermal/fireproof materials in a compact 200-foot hull where machinery spaces dominated crew areas.

- Limitations
- Class/era inference only - no hull-specific insulation survey, material list, builder work package, or asbestos specification located for Eagle No. 27. Names era-standard applications for a steam plant of this period, not confirmed installed materials. No quantity, no manufacturer attribution. The WWI-era build actually predates the heaviest documented Navy asbestos era (1930s-1970s) - the inference rests on period steam-plant practice, not on a documented survey of this class.

Two further yards are linked on secondary-compilation sourcing only: Charleston Naval Shipyard (moved there 16 July 1945 under the 6th Naval District) and Philadelphia Naval Shipyard (out of commission there April-July 1933).

- Finding type

- Finding
- CORRECTION / conflict register: NavSource's PE-27 spec block (710 t; beam 25'9"; draft 13'6"; complement 68) conflicts with the DANFS class characteristics (615 t; beam 33'1"; draft 8'6"; complement 5 officers + 56 enlisted = 61) and with USNI's class block (615 t full load; beam 25'6"; draft 8'6"; complement 73; 18.0 knots). NavSource's beam/draft values read as transposed/garbled against both other sources; DANFS and USNI agree on 615 t and 8'6" draft but disagree on beam (33'1" vs 25'6"). Commissioning is 14 July 1919 in DANFS/NavSource/MaritimeQuest/Wikipedia but 17 July 1919 in the Dreadnought Project table. This record carries DANFS values for class characteristics and flags, not reconciles, the rest.
