The HMAS Arrow was part of the Attack class series of 20 patrol boats ordered by the Royal Australian Navy. HMAS Arrow was commissioned into naval service on 3 July 1968, to serve as light coast patrol, search and rescue and replacing older craft in service at the time. She served as a training vessel for the Royal Australian Naval Reserves (RANR) until 1974, before undergoing a major refit and returning to active duties with the RAN. On 25 December 1974, she was driven ashore in Darwin by Cyclone Tracy and sank.

Introduced in Update "Drone Age", HMAS Arrow may be underestimated due to the evident lack of substantial firepower when compared to relatives at the rank such as the armed to the teeth Fairmile D (697) or Fairmile D (601). However, the single 40 mm QF (Quick-Firing) Mark VII gun can be highly effective, not only for the superior fire rate but also due to efficient ballistics, range, and penetration values. Experienced captains and newcomers alike may take advantage of this gun to make the Arrow shine. Given the lack of speed or additional armament, Arrow is straightforward in its playstyle, likely focusing on long-range gunnery to duel faster and smaller patrol boats that probably will be also better armed. In this regard, it is a good learning step to the similar playstyle of the later Brave Borderer.
