US Navy Reclassifies 19 Virginia-Class Submarines To Expand Guided Missile Strike Capability
Our take
The recent announcement of the US Navy’s reclassification of nineteen Virginia-class submarines to expand their guided missile strike capability represents a significant, albeit incremental, shift in naval strategy and a direct response to evolving geopolitical dynamics. Increasing the missile capacity of these submarines to up to 40 Tomahawk cruise missiles – a substantial jump from the previous 28 – underscores a renewed emphasis on submarine-launched strike capabilities. This decision arrives amidst a period of intensified strategic competition, particularly in the Indo-Pacific region, where the ability to project power discreetly and with precision is increasingly valuable. The context is clear: concurrent developments like China’s demonstration of the YJ-20 hypersonic missile launch from a Type 052D destroyer [China Demonstrates YJ-20 Hypersonic Missile Launch From Type 052D Destroyer For First Time] highlight the rapidly advancing capabilities of potential adversaries and necessitate a corresponding adaptation of US naval assets. Furthermore, India’s ambitious plans to build a 200-ship fleet by 2035 [India Races Towards A 200-Ship Fleet By 2035 To Counter China And Pakistan] further emphasizes the need for a robust and versatile naval presence to maintain regional stability.
The strategic rationale behind this upgrade extends beyond simply increasing firepower. Virginia-class submarines are uniquely suited for a variety of missions, including intelligence, surveillance, and reconnaissance (ISR), in addition to strike operations. The increased missile capacity enhances their ability to conduct dual missions, providing commanders with greater flexibility in responding to diverse threats. The reclassification doesn't involve significant structural modifications to the submarines, suggesting a relatively straightforward and cost-effective modernization. This approach aligns with the Navy’s broader strategy of leveraging existing assets while integrating new technologies. It's worth noting that recent RIMPAC exercises have showcased the importance of coordinated naval operations, including submarine warfare, among partner nations [Watch: U.S., Partner Nations Sink 2 Retired Warships In RIMPAC 2026 Live-Fire Exercise], further underlining the value of a modernized and versatile submarine fleet. The enhanced strike capability also allows for a more distributed and resilient response posture, reducing reliance on land-based launch platforms which are inherently more vulnerable.
The implications of this upgrade are multifaceted. From a technical perspective, it likely involves modifications to the submarines’ command and control systems, fire control systems, and potentially, the vertical launch tubes themselves. The integration of new missile variants, potentially including hypersonic weapons in the future, is another possibility. More broadly, this decision signals a continued investment in the submarine force, recognizing its crucial role in maintaining undersea dominance and projecting power globally. The shift reflects a recognition that the undersea domain is becoming increasingly contested, demanding a more sophisticated and capable submarine fleet. This also represents a subtle but important recalibration of the balance between surface and subsurface naval assets, acknowledging the unique advantages offered by submarines in a complex and contested environment. The increased missile loadout offers a greater capacity for executing diverse mission profiles, from conventional strike operations to potential responses to evolving threats.
Looking ahead, the modernization of the Virginia-class submarines is likely to continue, with a focus on incorporating emerging technologies such as artificial intelligence, advanced sensors, and unmanned underwater vehicles. The ability to integrate these technologies will be critical for maintaining a competitive edge in the undersea domain. A key question to monitor is whether this expansion of strike capability will be mirrored in other allied nations' submarine fleets, and how this development will influence the future of naval warfare. Furthermore, the development and deployment of countermeasures designed to detect and neutralize submarine-launched missiles will become increasingly important, leading to a continuous cycle of innovation and adaptation in the undersea domain.
The U.S. Navy is redesignating 19 planned Virginia-class nuclear-powered submarines equipped with the Virginia Payload Module (VPM) as guided missile submarines (SSGNs).
The reclassified submarines will include Virginia Block V and Block VI variants fitted with the 70-foot-long VPM, a hull extension that adds four large vertical launch tubes.
The upgrade will allow each submarine to carry 28 additional missiles, increasing their total Tomahawk cruise missile capacity to up to 40.
The Navy said the change shows the increased strike capability of the VPM-equipped submarines and their growing role in long-range precision strike missions, deterrence and future maritime operations.
The first VPM-equipped submarine, designated SSGN 803, is expected to enter service in fiscal year 2029. Deliveries of the 19 planned Virginia SSGNs are scheduled to continue through fiscal year 2038.
More missile capacity for Virginia-class submarines
The Virginia Payload Module is designed to increase the weapons capacity of Virginia-class submarines by adding four large-diameter launch tubes to the hull.
Each tube can carry seven Tomahawk cruise missiles, providing 28 additional missiles compared with standard Virginia-class attack submarines.
The submarines will also be capable of carrying future weapons, including the Intermediate-Range Conventional Prompt Strike hypersonic missile and other emerging payloads.
The Navy said the redesignation applies to 10 Block V Virginia-class submarines and nine planned Block VI submarines equipped with the VPM.
Although they will receive the SSGN designation, the submarines will remain part of the Virginia-class programme and will continue carrying out multiple missions, including anti-submarine warfare, anti-surface warfare, intelligence collection, mine warfare, irregular warfare and special operations support.
Replacing retiring Ohio-class SSGNs
The U.S. Navy begins retiring its four Ohio-class guided missile submarines, which have served as major conventional strike platforms.
The Ohio-class SSGNs can carry up to 154 Tomahawk cruise missiles and have also been used for special operations support, intelligence missions and underwater command functions.
The new Virginia SSGNs will offer improved stealth, survivability and flexibility, but they will not match the missile capacity of the Ohio-class submarines individually.
A single Ohio-class SSGN carries roughly four times more cruise missiles than a VPM-equipped Virginia submarine.
As a result, the Navy will need to deliver most of the planned Virginia SSGN fleet before reaching a similar level of overall undersea strike capacity.
Impact on US submarine fleet
The U.S. Navy works to expand its submarine fleet while managing several major construction programmes, including Virginia-class submarines, Columbia-class ballistic missile submarines and commitments under the AUKUS security partnership.
Because the Ohio-class SSGNs will retire before all 19 Virginia SSGNs enter service, the Navy expects a temporary reduction in undersea missile capacity during the transition period.
Vice Adm. Rick Seif, Commander of Submarine Forces, said the addition of high-volume precision strike capability to stealth submarines would support Distributed Maritime Operations and provide commanders with more flexible strike options.
The Navy said the new Virginia SSGNs will provide forward presence, strengthen deterrence and support conventional strike missions once they become operational.
