Another undersea cable damaged in Baltic Sea

Original Article ↗ Hacker News Discussion ↗

Incident and Technical Context

  • Swedish authorities opened a criminal investigation and seized a suspect vessel; multiple agencies (police, coast guard, defense) are involved.
  • Cable depth quoted around 50–80 m. Several commenters argue this is too deep for an ordinary accident and too shallow to be unreachable.

Cause: Sabotage vs Accident

  • Many participants see the pattern of recent cuts as intentional, likely involving ships dragging anchors over mapped cable routes.
  • Some note that vessels could be used as cheap tools for “hybrid” attacks: low-cost, deniable damage to communications resilience.
  • A linked article suggesting “accidents” is heavily criticized as contradicting named officials who call it deliberate.
  • A minority urges caution, citing ambiguous evidence and the historical existence of accidental damage; overall, sentiment strongly leans toward sabotage.

Diving and Cable Damage Feasibility

  • Discussion clarifies that typical recreational PADI certifications are limited to 18–40 m; 80 m requires serious technical training, helium mixes, long decompression, and often rebreathers.
  • Consensus: an 80 m dive is doable but specialized, not something a casual diver would use for covert sabotage; dragging ship anchors is easier.

Economic and Infrastructure Impact

  • Repair costs cited at roughly $1–3M per break plus downtime.
  • Some argue Baltic links are not globally critical and traffic reroutes, making this more of an annoyance.
  • Others stress that undersea cables as a class carry enormous economic value, so systematic attacks are strategically significant.

Legal and Maritime Policy Debates

  • Baltic access is geographically constrained by Danish waters; the Copenhagen Convention and UNCLOS define “innocent passage,” limiting new conditions like mandatory insurance.
  • Some argue Denmark/Sweden could leverage environmental or security provisions to impose stricter rules (insurance, inspections, compliance) on ships, especially those trading with Russia.
  • Others see legal and political barriers to turning the Danish straits into a choke point without reneging on treaties.

Deterrence and Response Options

  • Proposals include:
    • Requiring liability insurance for undersea infrastructure damage.
    • Seizing suspect vessels and cargo to fund repairs.
    • Blacklisting companies and captains involved.
    • Stronger sanctions on Russian fossil fuels and related logistics.
  • There is debate over punishing rank‑and‑file crew vs. focusing on owners, operators, and intelligence officers likely directing operations.

Broader Geopolitical Framing

  • Many connect the incident to Russia’s broader hybrid warfare: targeting infrastructure, spreading costs, and discouraging support for Ukraine.
  • Others tie it into a larger, emerging confrontation involving Russia, China, and Western allies, with references to recent Taiwan cable cuts and espionage cases.
  • Lengthy subthreads debate whether Russia is “winning” or heading for demographic and economic decline, and whether the EU can defend itself without US backing.
