The visual discussion identifies Manta as an early test bed and Moray as the more operationally ambitious follow-on. The XL-UUV offers a politically and institutionally attractive way for a nuclear-submarine navy to regain some conventional-submarine-like capacity without creating a separate manned SSK fleet. The vehicles may resemble small submarines, but their defining feature is uncrewed operation and the missions enabled by a much larger autonomous undersea platform. A later answer says ship or submarine deployment is contemplated, while leaving the launch arrangement at the conceptual stage.
