Editorial summaries
Ghost Shark (XL-AUV)
Anduril's Ghost Shark is an extra-large autonomous undersea vehicle (XL-AUV) and the production-maturity anchor of the defense-subsea cohort, extending the new-defense AI-first model (Anduril, Shield AI, Helsing, and Saronic on the surface) into the subsea regime. It is co-developed with the Royal Australian Navy and the Defence Science and Technology Group, leverages Dive-LD technology and Anduril's Lattice AI, and is backed by an A$1.7 billion RAN production contract (September 2025). Two cap-flags: the A$1.7B figure is the production contract, distinct from the A$140M 2022 co-development funding that aggregator reporting sometimes conflates with it; and detailed specs (around 12 meters length, plus displacement, endurance, and depth) are estimates, because the Australian Department of Defence withholds the design. It is defense procurement; there is no consumer price.
REMUS (100 / 300 / 620)
HII's REMUS family (REMUS 100/300/600/620) is the legacy-prime of the defense-subsea cohort: autonomous undersea vehicles for mine countermeasures, hydrographic survey, ISR, and electronic warfare, built by HII's Mission Technologies division, with a lineage dating to 2001 (Hydroid and Woods Hole Oceanographic Institution heritage; HII acquired Hydroid in 2020 for about $350 million). The REMUS 620 (introduced 2022) is a newer medium-class long-endurance UUV with up to 110 hours of endurance and 275 nautical miles of range, and a torpedo-tube-launched 'Yellow Moray' variant was fielded from the submarine USS Delaware in 2025. Cap-flag: large procurement-ceiling figures (such as a 200-vehicle order) are orders, not delivered counts. It is defense procurement; there is no consumer price.
