  "ORBE CIRCUMCINTO"15 June 1977 - 4 October 1996
  The motto for Orion according to the Latin Department of the University of London is either "Encompass the World" or "Belt around the World" or "Over the World". It is apparently very difficult to get a precise translation. When the crew first arrived in Greenock as commissioning crew the motto from the RAN Navy Board was "Over the World" but the crew preferred the Latin as HMAS Orion was the direct descendant from the old 8" cruiser and asked the Navy Board if they could keep the Latin. The College of Heralds and Navy Board (ADM Synot) agreed. It was changed back to "OVER THE WORLD" at a later date when Defence decreed that all mottos had to be in English.
 Orion is said in Greek mythology to be the son Hypieus, a mighty hunter of great beauty and gigantic strength. He was beloved of Eos the Greek Dawn goddess who carried him to Delos. Previously he had been struck blind by Dionysus the Greek god of wine. His eye sight was however restored upon exposing his eyeballs to the rays of Eos (Her task was to open the gates of the East for the sun). A hunter, he is alleged to have known Artemis, the sister of Apollo. Artemis became Orion's companion which made Apollo jealous. This caused Apollo to deceive Artemis, whereupon she shot Orion. After his death Orion was changed into a constellation in the form of a warrior wearing a girdle of three stars and a lion's skin carrying a club and sword.
 
 HMAS Orion was the sixth warship to be given the name Orion. The first five were all British warships. The first was a 74 gun ship launched on the Thames on the I st June 1787. She served in the French Wars. In a long fighting career she won the Battle Honours 'First of June' under Lord Howe in 1794, 'Groix Island' under Lord Bridport in 1795 and 'St. Vincent' under Sir John Jervis against the Spanish Fleet in 1797. Under Nelson she fought at the Battle of the Nile (1798) and at Trafalgar. In the final phases of the Napoleonic Wars she served in the Baltic before paying off to be broken up in 1814.
 
 The first hull section of the 5th Orion was placed in position on the 19th of April, 1972 and launched by Mrs John Armstrong, the Australian High Commissioner on the 16th of September, 1974 at Scott's Shipyards in Greenock, Renfrewshire, Scotland.
  HMAS Orion was the first HMA vessel ever to visit a German port.
 
 The submarine was due to enter service in 1975, but faulty high-power electrical cabling had been installed in Orion and sister boat Otama; stripping out and replacing the cabling delayed each submarine's construction by two years. The delay meant that the two boats could be fitted with Micropuffs rangefinding sonar during construction, and have additional electronic surveillance equipment installed
 HMAS Orion called at Spain, Greece, made a transit of the Suez Canal, visited the Seychelles and Singapore, making its Australian landfall at Cockburn Sound WA on the 20th June 1978, arriving at its home base Sydney on July 3, 1978.
 
 During her 19 years of service she steamed over 321,850 nautical miles. Orion was adopted prior to its commencement of building and was granted the rights to the Freedom of the City of Woolongong, NSW on the 27th September 1980.
 
 
   The Duke of Gloucester’s Cup was instituted in 1946. His Royal Highness Prince Henry, Duke of Gloucester, presented a silver cup to the Royal Australian Navy (RAN) as a prize for the ship that shot down the greatest number of sleeve targets during a calendar year.
 
 The RAN Gloucester Cup was initially assessed on the gunnery accuracy of RAN ships, based on the number of sleeve targets hit as a proportion of shells fired. This was quickly found to be impractical, and the criteria for the award was changed to "overall proficiency", based on each ship's level of operational efficiency during a calendar year; husbandry and seamanship; supply and administration; officer and sailor training; divisional systems, morale and discipline; and equipment reliability, maintenance and resourcefulness. As well as the silver trophy, a winning ship is allowed to paint a yellow star on the superstructure of the ship, which remains until the Cup is passed to a new winner.
 
 HMAS ORION won the CUP in 1985 and it was awarded to the Submarines crew by The Right Honourable Sir Ninian Stephen KG AK GCMG GCVO KBE QC    This allowed ORION to display a yellow star with a red E to prove to others that she had won the Cup.
