US Navy fears ballistic missile subs can be hit by drones, anti-tank rockets

The U.S. Navy is searching for better methods of protecting its missile subs, as well as the shore installations that support them.

Why this matters
Why now

The proliferation and increasing sophistication of low-cost drones and anti-tank weapons are creating new vulnerabilities for previously secure strategic assets.

Why it’s important

This highlights a fundamental shift in naval defense, where advanced adversaries or even non-state actors could threaten critical deterrent capabilities like ballistic missile submarines (SSBNs) and their support infrastructure.

What changes

The perceived invulnerability of strategic nuclear deterrents like SSBNs is being challenged, necessitating a rapid evolution in protective measures and naval doctrine.

Winners
  • · Defense contractors specializing in anti-drone and layered defense systems
  • · Naval security and anti-access/area denial (A2/AD) system developers
  • · Countries investing in asymmetric defense capabilities
Losers
  • · Traditional naval doctrine reliant on past threat models
  • · Submarine fleets without enhanced point defense capabilities
  • · Shore installations with inadequate layered security
Second-order effects
Direct

The US Navy will accelerate investment and development of counter-drone and perimeter defense technologies for both SSBNs and their support bases.

Second

Other nuclear powers will likely re-evaluate the security of their own strategic deterrents against similar asymmetric threats.

Third

This could lead to a strategic arms race in defensive capabilities, as global powers seek to ensure the survivability of their second-strike potential in a drone-augmented battlespace.
