Nimitz Class Nuclear Aircraft Carrier
The biggest warship currently in operation in the entire world: the Nimitz Class Nuclear Powered Aircraft Carrier is next. The service life of this ship extends over 50 years and the boat can go 20 years without needing to be refueled. This ship was laid out in 1975 and there are 10 in the United States Navy with this moniker. The Nimitz Class ship is over 1,000 feet in length and they can reach speeds of 30 knots. It takes a full 5,000 man crew to keep these boats ready and armed at all stations. At some point in the near future these ships are expected to be completely replaced by the Gerald Ford Class of aircraft carriers.
SAS Mendi F148
Named after the 1905 passenger ship that was converted into a troop ship during the First World War, the SAS Mendi joined the South African Navy in 2007. When these warships were commissioned, it traveled out to the site of the sunken ship it was named after and lay a wreath at its sinking site. Currently the SAS Mendi is actively taking part in anti-piracy activities along the eastern African coast.
