The Navy wants to develop and procure three types of large unmanned vehicles (UVs) called Large Unmanned Surface Vehicles (LUSVs), Medium Unmanned Surface Vehicles (MUSVs), and Extra-Large Unmanned Undersea Vehicles (XLUUVs). The Navy’s proposed FY2022 budget requests $434.1 million in research and development funding for these large UVs and their enabling technologies.
The Navy wants to acquire these large UVs as part of an effort to shift the Navy to a more distributed fleet architecture. Compared to the current fleet architecture, this more distributed architecture is to include a smaller proportion of larger ships (such as large-deck aircraft carriers, cruisers, destroyers, large amphibious ships, and large resupply ships), a larger proportion of smaller ships (such as frigates, corvettes, smaller amphibious ships, and smaller resupply ships), and a new third tier of large UVs. The Navy envisions LUSVs as being 200 feet to 300 feet in length and having full load displacements of 1,000 tons to 2,000 tons, which would make them the size of a corvette. (i.e., a ship larger than a patrol craft and smaller than a frigate).
The Navy wants LUSVs to be low-cost, high-endurance, reconfigurable ships based on commercial ship designs, with ample capacity for carrying various modular payloads—particularly anti-surface warfare (ASuW) and strike payloads, meaning principally anti-ship and land-attack missiles. Although referred to as UVs, LUSVs might be more accurately described as optionally or lightly manned ships, because they might sometimes have a few onboard crew members, particularly in the nearer term as the Navy works out LUSV enabling technologies and operational concepts. The Navy defines MUSVs as being 45 feet to 190 feet long, with displacements of roughly 500 tons, which would make them the size of a patrol craft.
The Navy wants MUSVs, like LUSVs, to be low-cost, high-endurance, reconfigurable ships that can accommodate various payloads. Initial payloads for MUSVs are to be intelligence, surveillance and reconnaissance (ISR) payloads and electronic warfare (EW) systems.
In marking up the Navy’s proposed FY2020 and FY2021 budgets, the congressional defense committees expressed concerns over whether the Navy’s acquisition strategies provided enough time to adequately develop concepts of operations and key technologies for these large UVs, particularly the LUSV, and included legislative provisions intended to address these concerns. In response to these markups, the Navy has restructured its acquisition strategy for the LUSV program so as to comply with these legislative provisions and provide more time for developing operational concepts and key technologies before entering into serial production of deployable units.
