"after bright stars, the ""Regulus"" was named after Regulus, the brightest star in the constellation Leo and one of the brightest stars in the night sky. Conversion began on 29 June 1984 at National Steel and Shipbuilding in San Diego, California. Her cargo hold was redesigned into a series of decks connected by ramps so vehicles can be driven into and out of the cargo hold for fast loading and unloading. She was also fitted with two sets of two cranes; one set located at midship capable of lifting 35 tons, and another set located aft capable of lifting 50"

The Regulus system as a whole is the twenty-first brightest star in the night sky with an apparent magnitude of +1.35. The light output is dominated by Regulus A. Regulus B, if seen in isolation, would be a binocular object of magnitude +8.1, and its companion, Regulus C, the faintest of the three stars that has been directly observed, would require a substantial telescope to be seen, at magnitude +13.5.

Babylonians called it ""Sharru"" (""the King""), and it marked the 15th ecliptic constellation. In India it was known as ""Maghā"" (""the Mighty""), in Sogdiana ""Magh"" (""the Great""), in Persia ""Miyan"" (""the Centre"") and also as ""Venant"", one of the four 'royal stars' of the Persian monarchy. It was one of the fifteen Behenian stars known to medieval astrologers, associated with granite, mugwort, and the kabbalistic symbol .

"Most of the Western names of stars, such as Algol or Betelgeuse, are Arabic in origin. In 1603 the Augsburg lawyer-uranographer Johann Bayer introduced the current classificatory system for the brighter stars, in which stars are identified as belonging to their constellations by Greek letters, in (roughly) descending order of brightness; so that Regulus, brightest star in Leo, is called ""α Leonis"", the brightest star of the Lion. Unpredictable observations in the heavens, including novas and supernovas as well as other phenomena in the heavens such as comets, meteors, parhelions, and even rainbows, were all collected under the name of"
