Navy Assesses Submarine Vulnerability to Drones, Anti-Tank Weapons; Seeks New Defenses
The timing is not coincidental. The recent PLA submarine-launched ICBM test (July 6) and Iran's anti-shipping strikes in the Hormuz (July 6-7) both demonstrate that subsurface and air-denial threats are operationalizing faster than Navy procurement cycles can absorb.
If the Navy's existing air-defense architecture (CIWS, ESSMs) cannot be retrofitted to Ohio-class boats without major hull modifications, the service faces a choice: accept a temporary vulnerability window during the next SSBN overhaul rotation, or delay maintenance to preserve deterrent availability. Either choice has second-order consequences for the attack submarine fleet and amphibious logistics — both of which compete for the same maintenance slots at Newport News and Groton.
If the Navy cannot field effective countermeasures against small-form-factor threats, the survivability assumption underlying the Ohio-class SSBN deterrent erodes — forcing a recalculation of second-strike credibility that allies depend on.
The vulnerability window spans both at-sea operations and pierside periods; the latter is a choke point where defenses must be improvised because traditional naval air defense systems are not designed for swarms of low-cost drones or shoulder-fired weapons. Watch whether NAVSEA's FY27 budget request includes a dedicated SSBN-hardening line item or whether this gets absorbed into existing submarine modernization accounts.
