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 of inexpensive drone and anti-tank rocket technology is democratizing defensive and offensive capabilities, forcing navies to rethink traditional security paradigms for high-value assets.

Why it’s important

The vulnerability of ballistic missile submarines (SSBNs) to increasingly accessible threats represents a fundamental challenge to strategic deterrence and national security, demanding urgent adaptation.

What changes

The perceived invulnerability of SSBNs and their supporting infrastructure is being re-evaluated, necessitating new defensive strategies and potentially impacting strategic force posture and procurement.

Winners
  • · Defence Tech companies (counter-drone/anti-armor)
  • · Naval architects (survivability focus)
  • · Cybersecurity firms (port security)
Losers
  • · Traditional naval defence contractors
  • · Submarine-focused industrial base (without adaptation)
  • · Legacy security protocols
Second-order effects
Direct

Increased investment in active and passive sub-surface and shore-based defensive systems.

Second

Revision of deployment strategies for SSBNs, potentially increasing operating depths or escort requirements.

Third

A global arms race in anti-submarine and counter-drone technologies, shifting power dynamics in naval warfare.
