- Abstract:
- Airpower enthusiasts concluded after World War I that “the bomber will always get through.”1 Fast, high-flying aircraft seemed to hold a decisive edge over air defenses and offered commanders the assurance they could attack targets deep inside an opponent’s territory. But airpower advocates’ spirits were quickly dampened during World War II by the advent of interceptor fighters, radar-guided artillery, and electromagnetic warfare (EW), which together demonstrated that bombers could be stopped—often with devastating results. Air forces adapted, adding escort fighters, radar jammers and decoys, and higher-altitude bombers to sustain their ability to strike behind enemy lines. During the Cold War, this move-countermove competition continued. New surface- and air-launched missiles targeted bombers, and countries developed specialized aircraft and weapons to suppress and destroy enemy air defenses or use stealth to avoid detection and targeting altogether. Today, the US submarine force faces a similar challenge. The US fleet of nuclear-powered attack submarines (SSNs) has long been considered an asymmetric advantage against potential adversaries like the People’s Republic of China (PRC) and Russia, which lacked robust and effective anti-submarine warfare (ASW) capabilities. Relying on this advantage, the US Department of Defense (DoD) has increasingly relied on SSNs to compensate for the impact of improved air defenses on the ability of bombers and strike fighters to execute attacks.2 However, the unfailing ability of US SSNs to reach their targets is eroding as emerging technologies and weapons proliferation combine in new approaches to ASW that could neutralize America’s undersea advantage. During the last decade, the PRC and Russian Federation began fortifying their undersea defenses in the South and East China Seas and Arctic Ocean, respectively. Leveraging geographic constraints, US adversaries have instrumented these bastions with networks of fixed and mobile acoustic and non-acoustic sensors, complemented by aircraft and ships capable of pouncing on contacts or deploying dense mine barriers.3 Improved adversary defenses could degrade or defeat US undersea operations, preventing US submarines from conducting critical missions such as sinking a Chinese invasion fleet or tracking Russian ballistic missile submarines (SSBNs). To sustain its offensive undersea advantage, the US Navy will need to take some lessons from air warfare and begin supporting submarines with systems designed to suppress or destroy enemy undersea defenses. This imperative will fundamentally shift the paradigm for US submarine operations from “alone and unafraid” to “it’s all about team.” Moreover, the emergence of new generations of capable long-range active sonars will demand that the US undersea force increasingly rely on jamming and deception to counter enemy sensors, much as their counterparts already do above the water. The US submarine force will need to learn how to use noise, rather than avoid it. The Navy should pursue four lines of effort, outlined below, to sustain its offensive undersea advantage. Except for features to be incorporated into the next-generation nuclear-powered attack submarine, the SSN(X), the concepts and capabilities proposed in this report leverage mature or maturing technologies and can be fielded within five years. Implementing these recommendations will require the US Navy to refine its use cases for offensive undersea warfare to use available uncrewed vehicle technologies, rather than continue pursuing purpose-built systems that may take a decade or more to be fielded.4
