Armidale-class patrol boat
 The Armidale class is a class of patrol boats built for the Royal Australian Navy (RAN). Planning for a class of vessels to replace the fifteen Fremantle class patrol boats began in 1993 as a joint project with the Royal Malaysian Navy but was cancelled when Malaysia pulled out of the process. The project was reopened in 1999 under the designation SEA 1444 with the RAN as the sole participant.
