Source-derived summary

The Loening XSL was an American submarine-based reconnaissance flying boat designed and built by Grover Loening Aircraft Company for the United States Navy.

Design and development

First flown in 1931, the Loening XSL was a lightweight flying-boat designed to be folded up and stored in an 8-foot-diameter watertight tube on the deck of a submarine. It was a single-seat, mid-wing monoplane powered by a 110 hp (82 kW) Warner Scarab radial engine mounted above the wing driving a pusher propeller. Originally designated the XSL-1 by the Navy, it was re-designated XSL-2 in 1932 when it was re-engined with a 160 hp (119 kW) Menasco B-6 engine. Only the prototype was built; it was not ordered into production.

Editorial summary

The public source identifies “Loening XSL” as type of aircraft. This brief keeps that definition visible, then builds a research path around Loening, type and aircraft.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1931, 1932, 1962, 1979—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Loening, type and aircraft providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Loening XSL”, the useful work is to connect “type of aircraft” to the records capable of establishing context and consequence.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 27, 2025. The linked authority identifier is Q6666568. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1931, 1932, 1962 and 1979.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
