Austal* Congress has demanded the U.S. Navy look into buying a new class of small warships loaded with missiles or adding bolt-on launchers to existing vessels, including amphibious warfare and auxiliary support types, to help increase its combat capacity. Lawmakers ordered the study in response [to major delays in work]() on the Navy's future [*Constellation* class frigates]() in large part due to extensive changes in the core design. There is already a long-standing debate about whether the 32 vertical launch system (VLS) cells on those ships are adequate to support their expected mission sets, something *The War Zone* [has previously explored in detail](). The Senate Armed Services Committee included a call for what it termed a "highly producible small surface combatant study" in [a report accompanying a new draft]() of the annual defense policy bill, or National Defense Authorization Act (NDDA), for the 2025 Fiscal Year, which was published earlier this week. This follows a [series of damning reports]() on the status of the Navy's *Constellation* class frigate program. The future USS *Constellation* is currently under construction and is set to be delivered in 2029, three years behind schedule. The second ship in the class, which [will be dubbed USS *Congress*](), is also facing years-long delays. The Navy has four more [of the frigates on order](). ![]() *A rendering of the fourth planned *Constellation* class frigate, the future USS *Lafayette* (FFG-65). *USN** "The committee is concerned with the projected decline in the number of Navy battle force ships and fleet-wide vertical launch system (VLS) capacity between now and 2027," the section of the report on the small surface combatant study says by way of introduction. "The President’s budget request for fiscal year 2025 would procure 6 battle force ships while retiring 19, contributing to these projected near-term declines. Given the ongoing naval buildup by the People’s Republic of China, the committee believes these projected declines increase risk to U.S. forces in the U.S. Indo-Pacific Command area of responsibility." A key factor in this is the ongoing retirement of all of [its remaining *Ticonderoga* class cruisers](), each of which has 122 VLS cells. The service just held a decommissioning ceremony for one of these ships, the USS *Vicksburg*, [on June 28](). The Navy is also looking to decommission [its four *Ohio* class guided missile submarines](), each of which can carry up to 154 Tomahawk cruise missiles, by the end of the decade. When it comes to the Navy's surface fleets, the [stated plan]() is for [Flight III *Arleigh Burke* class destroyers](), which have 96 VLS cells, and a new future destroyer design, [currently referred to as DDG(X)](), to steadily fill the resulting gap. The *Constellation* class frigates, as well as [future uncrewed surface vessels](), will also help bolster the Navy's overall VLS capacity. ![]() *The Ticonderoga class cruiser USS Vicksburg seen pierside in Norfolk, Virginia during the ship's decommissioning ceremony on June 28, 2024. *USN** However, "the committee does not believe the Department of the Navy is adequately emphasizing near- and medium-term capacity requirements," the recently released Senate Armed Services Committee report continues. "With the delivery of the first *Constellation* class frigate delayed 3 years and procurement of the large, unmanned surface vessel (LUSV) not scheduled to begin until fiscal year 2027, the committee believes the U.S. Navy needs to focus more on supplementary options for increasing ship numbers and missile-launching capacity in the nearer term." The Secretary of the Navy now has until April 1, 2025, to produce a study that addresses the following five points: - "Examine a crewed variant of the LUSV that can serve as a pathfinder for the unmanned version while adding near-term missile-launching capacity, including a discussion of any need for waivers of survivability or other requirements, given the non-crewed original design of the LUSV." - "Examine other foreign, commercial, or U.S. Government ship designs that are mature and could be adapted with minimal modifications to produce a crewed small surface combatant." - "Examine existing Navy ships (including amphibious and support ships) or commercial-type hulls that could be quickly modified into missile-firing ships through the addition of VLS, bolt-on, or containerized missile launchers." - "Evaluate the time to field each platform, as well as the platform’s producibility within current supply chain and industrial base constraints." - "Provide cost estimates and manpower impacts for each platform." The second stipulation here is immediately notable given that this was the exact plan for the *Constellation* class, a design ostensibly based on that of the [Franco-Italian Fregata Europea Multi-Missione]() (FREMM), or European Multi-Mission Frigate. As it stands now, the *Constellations* will have around 15 percent commonality with their parent design and the changes could negatively impact the top speed and other operational capabilities of the ships, as well as schedule and cost, as you can read more about [here](). The Senate Armed Services Committee criticized the management of the Navy's new frigate program elsewhere in its recent report, which also recommended blocking funding for the ships until the service can provide more assurances that the design is stable. ![]() *A graphic the Navy previously released detailing differences between the *Constellation* class and its parent FREMM design. *USN via CRS* An infographic with details about how significantly the Constellation class design will differ from the FREMM parent. *USN via CRS** "The scale and scope of these changes \[to the *Constellation* class design\] call into question the basis of the U.S. Navy’s original program justification to Congress and the fixed price contract awarded to the shipbuilder," the Senate report notes. "If the proposed design was insufficient to meet U.S. Navy standards to the degree suggested by the reported 15 percent commonality figure, then the contract award suggests that there was a severe breakdown between the assumptions of the source selection evaluation board and the senior technical authority." Furthermore, "the Secretary of the Navy certified to Congress that basic and functional design were complete prior to the start of construction in August 2022, but U.S. Navy officials now estimate that such maturity will not be reached until more than 2 years later. The committee believes this constitutes a misrepresentation of the facts certified by the Secretary of the Navy." The report also stressed that the members of the Senate Armed Services Committee remain supportive, in broad strokes, of the *Constellation* class frigate effort as an important future addition to the Navy's fleets. When it comes to the [Navy's LUSV program plans](), the current focus is on acquiring a fleet of uncrewed vessels with displacements between 1,000 and 2,000 tons and between 16 and 32 VLS cells. The service had previously hoped to begin fielding the first of these drone ships in the 2025 Fiscal Year. ![]() *A rendering of a notional LUSV design with a VLS array at the bow end. *Austal** The Navy has already been experimenting with various tiers of USVs for use in number of roles, which has [included live-fire missile launches](), for years now. Many of these [existing USV designs]() are [really crew-optional](). The expectation has been that any operational LUSVs are likely to have baseline uncrewed capabilities that will be incrementally expanded upon, as well. https://twitter.com/DeptofDefense/status/1433852377870839808 The idea of expanding Navy missile launch capacity by adding bolt-on systems to other existing ships in its inventory, especially cargo vessels and other auxiliary types, including commercial-owned ones, [is also not new](). In fact, Congress demanded a [previous study into doing just this]() back in 2021 before it would approve any funding for the LUSV program. The [*San Antonio* class amphibious warships]() the Navy has now were also originally supposed to have two Mk 41 VLS arrays, though these were not installed in the end. There [have long been discussions]() about [refitting those vessels]() to finally give them this capability. The Navy has been eying many of these options for years as part of broader distributed concepts of operations involving ships loaded with missiles, [including]() dedicated [arsenal ships](), networked together. Those vessels would not necessarily need to have the same diversity of capabilities as a general-purpose warship, especially when it comes to sensors, and would be able to feed in targeting data from other sources. This, in turn, would allow those platforms to be deployed across a relatively broad area, creating both new tactical opportunities and targeting challenges for opponents. This all fits in with [evolving 'kill web' concepts]() the entire U.S. military is increasingly exploring that are ever more important in the face of similarly expanding threat capabilities, especially among near-peer competitors like China. ![]() *Artwork from the Defense Advanced Research Projects Agency showing a notional arsenal ship dating back all the way to the 1990s. *DARPA** Arming auxiliaries or commercially sourced vessels does have its drawbacks. In particular, these designs are not designed to the same survivability requirements as true warships. There are a number of add-on and containerized missile launch systems on the market now that could meet this need. The Navy has already been testing a containerized launcher called the Mk 70, which is derived from the Mk 41 Vertical Launch System found on various U.S. and foreign warships, [on crewed and uncrewed vessels](), as well as [in a ground-based configuration](). ![]() *A Lockheed Martin model depicting a large uncrewed surface vessel armed with Mk 70 containerized launchers. *Joseph Trevithick* A Lockheed Martin model depicting a large uncrewed surface vessel armed with Mk 70 containerized launchers. This model also shows containers with electronic warfare systems at the rear. *Joseph Trevithick** BAE Systems is also on contract with [the U.S. Navy to develop]() the Next Generation Evolved Sea Sparrow Missile Launch System (NGELS). NGLES will primarily serve as a replacement for existing launchers used to fire [RIM-162 Evolved Sea Sparrow Missile]() (ESSM) on Navy ships and those of America’s NATO allies. NGELS is based on BAE's [Adaptive Deck Launcher (ADL)](), an angled deck-mounted launch system designed to fire various missiles from the same canisters used with the Mk 41 found on various U.S. and foreign warships. ADL has a modular and scalable design intended to make it relatively easy to integrate on a wide variety of ships, crewed and uncrewed. https://twitter.com/BAESystemsInc/status/1744752151149044131 Systems like the Mk 70 or the ADL, though flexible in how they can be integrated, does have significantly less capacity than a typical built-in VLS array. It is worth noting here that the Navy [has downplayed]() using total VLS cells across its fleets as a metric of its combat capacity in the past. The service has pointed to having increasingly more advanced weapons to put in those launchers and other new capabilities as helping to offset losses in overall VLS capacity. At the same time, the [crisis in and around the Red Sea]() since October of last year and [the U.S. response]() to [Iranian retaliatory missile and drone attacks]() on Israel in April [have reignited concerns]() about the Navy's fleet-wide missile capacity. Serious questions have also emerged about the service's ability [to replenish its missile stocks]() and actually get those weapons to ships that need them. Devising ways for Navy ships to re-arm at sea has [become a particularly high priority](). All of these demands would only be greater in the context of any potential high-end conflict, such as one in the Pacific against China. There is also the matter of China's [massive advantage in total shipyard capacity]() compared to that of the United States. This presents its own concerns in the context of the delays with the *Constellation* class [and other Navy shipbuilding programs](), and could present limitations for the service when it comes to exploring alternatives in the near term. What other missile-toting ship options the Navy brings back to Congress next year remains to be seen as it continues to struggle ahead with the *Constellation* class frigates. *Contact the author:* [*joe@twz.com*]() ## Author Joseph is *TWZ’s* Deputy Editor, helping to oversee the site’s highly experienced and dedicated team, while also writing informative and impactful defense and national security content.
