Memo to Trump: Cancel the sea-launched nuclear cruise missile

Bulletin, By David Kearn | January 17, 2025

Mr. President, we urge the cancellation of the SLCM-N program. It is unnecessary, costly, and makes the job of rebuilding our military more difficult.

As you know, the SLCM-N program was initiated during your first term. It was canceled by the Biden administration, but Congress allocated funds to revive the program in the 2024 National Defense Authorization Act. However, with the benefit of study and analysis, the Navy has signaled opposition to the program, viewing it as costly distraction from pressing modernization priorities, a strain on the already struggling defense industrial base, and an unnecessary complication of the missions of the fast attack submarine fleet.

…………………………………………………….. Redundancy

The United States already deploys significant conventional military assets in key regions and can quickly augment them by moving in nuclear weapons as needed to signal to adversaries that transgressions will have severe consequences. First, the Long-Range Standoff Missile (LRSO) deployed on either B-52 or B-21 bombers—while not technically classified as a “tactical weapon”—will possess the range, penetrability, and single-kiloton yield to provide the United States with the flexibility to respond to the threatened or actual use of nuclear weapons by an adversary in a proportional way without resorting larger strategic systems. Second, the B61-12 gravity bomb provides a low-yield munition that can be delivered by bomber and strike aircraft. Finally, thanks to your leadership during the first administration, the United States also possesses a low-yield variant of the Trident II D-5 submarine-launched ballistic missile (SLBM). In short, the United States possesses adequate nuclear capabilities to provide limited, flexible options if you or a successor would ever need them.

Costs

The expected costs of the SLCM-N—initially estimated at $10 billion but likely to be higher—are significant. The Navy will do its best to implement your preferred policies, but the SLCM-N program will require an “entirely new workforce and industrial base” to deliver this single system. The new missile cannot simply utilize an existing conventional Tomahawk cruise missile fitted with a nuclear warhead, as advocates initially assumed.

Beyond program costs, the Navy’s Strategic Systems Program office already has a “very full plate” of other programs, including upgrading the Trident II D-5 SLBM, as well as the new Conventional Prompt Strike hypersonic missile to be deployed on destroyers and attack submarines. A new program devoted exclusively to SLCM-N would divert workforce and resources away from these important programs at a time when industrial capacity and budgets are already stretched thin.

………………………………… Recommended course of action

We urge that you work with Congress to cancel the SLCM-N program. In doing so, you may prefer to recommend that the allocated funds be devoted to existing conventional Navy programs or toward further investment in flexible nuclear programs, such as the long-range standoff (LRSO) cruise missile…………. more https://thebulletin.org/2025/01/memo-to-trump-cancel-the-sea-launched-nuclear-cruise-missile/?utm_source=ActiveCampaign&utm_medium=email&utm_content=Memos%20to%20Trump%20%28he%20might%20actually%20like%29&utm_campaign=20250120%20Monday%20Newsletter
