Abstract: It was about two months after V-E Day that reports began to trickle in to our section of the Bureau of Ships (Design of Navigational Equipment) about a German gyrosextant which had been found aboard German submarines. In July the first one arrived. The brief instructions attached to the lid of the sextant box did not describe the instrument, but a visit to NAS, Philadelphia, where similar instruments were reported under test, revealed that the instrument was, fundamentally, the German bubble sextant, the only change being the replacement of the bubble by the gyro unit. An instruction booklet for the bubble sextant came with the second gyro-sextant, and after laboratory tests at the Naval Observatory, tests at sea were initiated.
