OVERVIEW: The SSG 75 Waller [Collins Class] is a diesel-electric attack submarine (SSK) operated by the Royal Australian Navy. She represents a significant element of Australia's maritime defence capabilities, designed for long-range patrol and operations within the Indo-Pacific region.

DETAILS:
The Collins class was conceived in the 1980s as a replacement for the Oberon-class submarines. The design prioritized extended operational range and endurance, low acoustic signature, and advanced combat systems to effectively patrol Australia’s vast maritime territories. The design was a collaboration between Kockums of Sweden and the Australian Submarine Corporation (ASC). The class encountered numerous technical challenges during its development and early service life, particularly with its combat system and noise characteristics. However, these issues have been largely addressed through extensive upgrades and modifications over the years. The Collins class submarines remain the largest conventionally powered submarines in the world, reflecting Australia's strategic need for long-range underwater capabilities.

The SSG 75 Waller, as a Collins-class submarine, is primarily designed for anti-submarine warfare (ASW), anti-surface warfare (ASuW), intelligence gathering, and covert operations. The platform’s endurance allows for extended deployments, providing a persistent underwater presence in strategically important areas. While lacking dedicated anti-air warfare (AAW) capabilities in the traditional sense, the submarine's stealth and sensors contribute to overall situational awareness and force protection. The vessel’s ability to conduct covert surveillance and reconnaissance missions enhances Australia’s ability to monitor potential threats and maintain maritime domain awareness. SSG 75 Waller's capabilities contribute significantly to regional security and stability.

The Waller is equipped with a comprehensive suite of sensors. The Narama SHORTASS is a crucial component of the vessel's electronic support measures (ESM) suite, providing the capability to detect, identify, and geolocate radio frequency emissions from surface ships, aircraft, and land-based installations. The Type 1007 navigation radar provides surface search and navigational capabilities. The TSM 2253 PVDF flank array sonar is a key asset for passive detection, enabling the submarine to listen for distant targets with high accuracy. The TSM 2233M Scylla, with its DSUV 2H (possibly a towed array) and DUUA 2D, offers advanced active and passive sonar capabilities, further enhancing underwater surveillance. The Manta XL towed array provides long-range acoustic surveillance. The TSM 2255 integrated sonar suite integrates and processes data from various sonar sensors. The SATEPS system allows for satellite communication and navigation updates. Finally, the CK043 / CH093 Periscope Suite provides both visual and electronic observation capabilities above the surface.
