Vickers, Tube Alloys and possible Manhattan connections

Was Vickers a subcontractor on the Manhattan Project?

Direct subcontracting is uncertain. Participants recall possible connections through Tube Alloys, enrichment research and ignition-system work.

One participant is unaware of direct Manhattan Project involvement but connects Vickers with Tube Alloys and its later merger into the American effort. Possible ignition-system and laboratory work is recalled uncertainly. Another remembers Vickers interests contributing to enrichment research. The company's chemical businesses and refining capabilities are subsequently linked to its wider military research capacity. This does not establish a firm subcontracting history.
