Australia’s Collins-Class in 2025: Navigating Obstacles on the Path to AUKUS

Join us as we explore the current state of Australia’s Collins-class submarine fleet in 2025, a vital part of the nation’s naval defence. Comprising six diesel-electric submarines—HMAS Collins, Farncomb, Waller, Dechaineux, Sheean, and Rankin—these vessels, developed in partnership with Sweden’s Kockums, overcame early technical issues to become one of the world’s most advanced conventional submarine forces. Operating across the Pacific and Indian Oceans, they safeguard trade routes and deter threats but now face challenges from an aging platform, crew shortages, and maintenance demands. With a $4–5 billion Life-of-Type Extension set to begin in 2026 as a bridge to Australia’s nuclear-powered future under AUKUS, we examine their high-stakes missions, from the 1999 East Timor operation to RIMPAC exercises, and upgrades like the AN/BYG-1 combat system.
