HMAS Anzac (FFH 150) is the lead ship of the Anzac-class frigates in use with the Royal Australian Navy (RAN) and the Royal New Zealand Navy (RNZN). Entering Australian service in 1996, the frigate operated as part of the INTERFET peacekeeping taskforce in 1999. In 2003, she was involved in the Battle of Al Faw and became the first RAN ship to fire in anger since the Vietnam War. The ship is operational as of 2021.

The Anzacs are based on Blohm + Voss' MEKO 200 PN (or Vasco da Gama class) frigates, modified to meet Australian and New Zealand specifications and maximise the use of locally built equipment.

Each frigate has a 3,600-tonne (3,500-long-ton; 4,000-short-ton) full load displacement. The ships are 109 metres (358 ft) long at the waterline, and 118 metres (387 ft) long overall, with a beam of 14.8 metres (49 ft), and a full load draught of 4.35 metres (14.3 ft).

Maximum speed is 27 knots (50 km/h; 31 mph), and maximum range is over 6,000 nautical miles (11,000 km; 6,900 mi) at 18 knots (33 km/h; 21 mph); about 50% greater than other MEKO 200 designs.

The main armament for the frigate is a 5-inch 54 calibre Mark 45 gun, supplemented by an eight-cell Mark 41 vertical launch system (for RIM-7 Sea Sparrow or RIM-162 Evolved Sea Sparrow missiles) and two 12.7-millimetre (0.50 in) machine guns.
