The SLCM-N will likely be deployed on surface ships, attack submarines, or a combination of the two. In 2018, General Hyten specified that DOD would examine deploying SLCM-Ns on different types of submarines and the Zumwalt-class destroyer. While the Ohio-class, or future Columbia-class SSBNs, will likely not be an option, the Virginia-class attack submarines (SSNs) would be the likeliest candidate for submarine deployment. The U.S. Navy currently maintains 19 Virginia-class boats and will continue procuring about two more per year as the older Los Angeles-class SSNs retire. The Virginia-class has both vertical launch tubes and torpedo tubes that can carry the conventional TLAMs.
Development
Most missiles are dual-capable, and the DF-17 missile might be able to carry a nuclear-capable hypersonic weapon. Additionally, China’s H-6K bomber can carry nuclear weapons, and China’s sea-based capabilities will improve with the development of the JL-3 SLBMs. For instance, should China decide to forcefully take Taiwan, it can use its regional nuclear forces to coerce the United States and constrain U.S. response options. The SLCM-N is a theater-range cruise missile armed with a nuclear warhead that can be launched from surface ships or submarines. During the Cold War, the United States deployed the TLAM-N on surface ships and submarines from 1983 to 1991 as part of its strategy to deter a Soviet attack on Europe. In particular, the TLAM-N supported the strategy of deploying nonstrategic nuclear weapons to link conventional forces in Europe with the U.S. strategic nuclear arsenal.
Ballistic missile
In addition to the cost of the W80-4 warhead itself, the cost estimate for completing the LRSO has not been announced but $227 million are programmed through 2019. In addition to these weapons costs, integration on the B-2A and next-generation long-range bomber (LRS-B) will add hundreds of millions more. “A low-yield, non-ballistic nuclear capability to deter, assure and respond without visible generation (similar to the characteristics of SLCM-N) offers additional options and supports an integrated deterrence approach,” Cotton wrote.
The Nuclear Sea-Launched Cruise Missile: Worth the Investment for Deterrence
It also precipitated a public backlash across Western Europe; it underscores the high threshold to effectively signal commitment in the face of an acute threat. The deployment of nuclear cruise missiles, while having the benefits of avoiding domestic political challenges of deployment of strike assets on the home territories of nervous allies, is likely to have only marginal reassurance benefits, at best. Third, a SLCM-N’s cruise missile trajectory contributes to the U.S. ability to effectively hold targets at risk and complements ballistic missile options.
Their expanding and diversifying arsenals may provide both nations options to escalate conflicts in novel ways to which the current U.S. nuclear posture would be challenged to respond. This trend erodes deterrence; China and Russia may be more willing to take risks or even strike first as the credibility and efficacy of a U.S. response diminish. Adding the SLCM-N to the U.S. arsenal is therefore stabilizing because it would begin to rectify this imbalance. But their description of the LRSO mission sounds a lot like old-fashioned nuclear warfighting that will add new military capabilities to the arsenal in conflict with the administration’s promise not to do so and reduce the role of nuclear weapons.

Large submarines (for example, Echo and Oscar classes) were developed to carry these weapons and shadow United States battle groups at sea, and large bombers (for example, Backfire, Bear, and Blackjack models) were equipped with the weapons in their air-launched cruise missile (ALCM) configuration. While air-based nuclear weapons remain a critical part of U.S. strategy, a sea-based regional nuclear missile can bolster these existing regional capabilities by more effectively operating against Russian and Chinese air defense systems. Sea-based, survivable submarines or even destroyers can operate in an extensive area and are difficult to find and destroy. Submarines are difficult to detect, and even Navy destroyers dispersed throughout the waters can make targeting difficult, especially if they have low observable characteristics, such as the Zumwalt-class.
SEOUL, South Korea (AP) — North Korea said Thursday it conducted its first flight test of a new cruise missile, as it expands its military capabilities in the face of deepening tensions with the United States and neighbors. The SLCM-N would provide a regionally present, sea-based, survivable option needed to fill a gap in U.S. nuclear deterrence capabilities. “We conducted the last successful test of the Burevestnik nuclear-powered global-range cruise missile,” he said without elaborating.
India is currently developing hypersonic BRAHMOS-II which is going to be the fastest cruise missile. The USAF adopted the AGM-86 for its bomber fleet while AGM-109 was adapted to launch from trucks and ships and adopted by the USAF and Navy. The truck-launched versions, and also the Pershing II and SS-20 Intermediate Range Ballistic Missiles, were later destroyed under the bilateral INF (Intermediate-Range Nuclear Forces) treaty with the USSR.
North Korea’s cruise missiles are among its growing arsenal of weapons aimed at overwhelming missile defenses in South Korea and Japan. They supplement the country’s huge lineup of ballistic missiles, including intercontinental ballistic missiles designed to reach the U.S. mainland. The 2018 NPR proposed the SLCM-N to address the threat environment, which has changed dramatically over the past decade.
This research became known as Project Pluto, and was directed by Theodore Charles (Ted) Merkle, leader of the laboratory's R Division. Originally carried out at Livermore, California, testing was moved to new facilities constructed for $1.2 million on 21 square kilometers (8 sq mi) at NTS Site 401, also known as Jackass Flats. The need to maintain supersonic speed at low altitude and in all kinds of weather meant that the reactor had to survive high temperatures and intense radiation. Ceramic nuclear fuel elements were used that contained highly enriched uranium oxide fuel and beryllium oxide neutron moderator. Finally, senior US military leadership must stay focused on this project—and on achieving it in parallel with other projects.
In a speech at a forum of foreign policy experts, Putin announced that Russia has effectively completed the development of the Burevestnik cruise missile and the Sarmat heavy intercontinental ballistic missile and will work on putting them into production. MOSCOW (AP) — Russia has successfully tested an experimental nuclear-powered cruise missile, President Vladimir Putin said Thursday, while also warning that the country’s parliament could revoke its ratification of a treaty banning nuclear tests. Often variants of the same missile are produced for different launch platforms (for instance, air- and submarine-launched versions). Nuclear weapons delivery is the technology and systems used to place a nuclear weapon at the position of detonation, on or near its target. Since the next-generation long-range bomber would also be the launch platform for those conventional weapons, it will be exposed to the same risks with or without a nuclear LRSO.
The first true weather satellite, the TIROS-1 was launched on the Thor-Able launch vehicle in April 1960.[10] The PGM-17 Thor was the first operational IRBM (intermediate ballistic missile) deployed by the US Air Force (USAF). The Soviet Union's first fully operational weather satellite, the Meteor 1 was launched on 26 March 1969 on the Vostok rocket,[citation needed] a derivative of the R-7 ICBM. While the first modern ballistic missile designed is the basis of contemporary rocket- and missilery, it never carried a nuclear warhead. Lee Sung Joon, spokesperson of South Korea’s Joint Chiefs of Staff, said that the missiles flew a shorter distance than previous North Korean cruise missile launches, which he said suggested that the North was trying to improve the performance of existing systems.
