HMAS Vampire was a V-class destroyer of the Royal Navy (RN) and Royal Australian Navy (RAN). Launched in 1917 as HMS Wallace , the ship was renamed and commissioned into the RN later that year. Vampire was lent to the RAN in 1933, and operated as a depot tender until just before World War II.
The dress blue insignia consists of a perched eagle (or "crow") with spread wings atop a rating mark, with three chevrons and one "rocker" above the rating mark. Inverted five-point stars above the crow denote the rank of senior chief (one star) or master chief (two stars). All other uniforms use the collar device to denote rank.
HMAS Vampire was the third of three Australian-built Daring-class destroyers serving in the Royal Australian Navy (RAN). One of the first all-welded ships built in Australia, she was constructed at Cockatoo Island Dockyard between 1952 and 1959, and was commissioned into the RAN a day after completion.
For example, if a sailor has the pay-grade of E-5 (rank of petty officer second class) and the rating of boatswain's mate, then combining the two—boatswain's mate second class (BM2)—defines both rank and rating in formal address or epistolary salutation. Thus, boatswain's mate second class (BM2) would be that sailor's rate. [1]
However, the rank of fleet admiral still remains listed on official rank insignia precedence charts and, if needed, this rank could be reestablished at the discretion of Congress and the President. All five-star officers are, technically, unable to retire from active duty. [5] The last living fleet admiral, Chester W. Nimitz, died in 1966.
Star Destroyers are capital ships in the fictional Star Wars universe. Star Destroyers were produced by Kuat Drive Yards, later Kuat-Entralla Engineering, and serve as "the signature vessel of the fleet" for the Galactic Empire, the First Order, and the Sith Eternal in numerous published works including film, television, novels, comics, and video games.
Effective 1 October 2001, the U.S. Navy developed a "Lead-Follow" arrangement among its type commands wherein one type commander is designated the senior lead for the specific "type" of weapon system (i.e., naval aviation, submarine warfare, surface warships) throughout the entire operating U.S. Fleet as it pertains to modernization needs, training initiatives, and operational concept development.
Rhett Allain, an associate professor of physics at Southeastern Louisiana University, estimated in a 2017 article for Wired that the Hammerhead's engines in Rogue One would have had to generate 2 × 10 11 (or 200 billion) Newtons of force to push the Star Destroyer: 6,000 times the amount of thrust force generated by a Saturn V rocket.
