US and Royal Navy Torpedo Test Meets Serbia’s Elbit Drone Push—What’s the real tech race?

The US Navy and the Royal Navy conducted a training-related torpedo exercise in which a Mark 48 heavyweight torpedo was loaded aboard the USS California (SSN-781), a Virginia-class submarine, during exercises in Spain in January 2017, as highlighted by National Interest. The imagery and description underscore that heavyweight undersea munitions remain a core capability being rehearsed with allied forces, not just stored. While the article is framed as a historical training snapshot, it signals continuity in readiness practices and interoperability between US and UK naval communities. In parallel, Haaretz reports that a lawyer associated with Israeli Prime Minister Benjamin Netanyahu was present at Serbia’s newly established Elbit drone factory, pointing to active engagement around defense technology transfer and local production. Geopolitically, the cluster links two different but complementary tracks of military modernization: undersea lethality and unmanned aerial systems manufacturing. The Mark 48 loading and allied training context benefits the US and UK by sustaining credible deterrence and improving joint operating procedures, especially for submarine crews and weapons handling. Serbia’s Elbit drone factory, meanwhile, suggests Belgrade is seeking to narrow capability gaps through partnerships that can deliver faster scaling of ISR and strike-adjacent platforms, potentially altering regional military balances in the Western Balkans. Israel’s apparent involvement via high-level legal representation indicates that defense-industrial ties are being used as a diplomatic and commercial lever, while also raising questions about how third-party actors may respond to Serbia’s growing UAV ecosystem. On the markets side, the direct economic linkage is less immediate for the torpedo exercise, but it still matters for defense procurement expectations and industrial planning in naval weapons and training services. The drone-factory angle is more market-relevant because it implies local assembly, component sourcing, and long-run sustainment contracts that can influence defense supply chains and export-control compliance costs. Separately, Lowe’s launching a drone delivery service with DoorDash and Alphabet introduces a civilian logistics use case that can accelerate drone autonomy, navigation, and fleet-management tooling—technologies that often have dual-use pathways into defense. If drone delivery scales, it can increase demand for sensors, batteries, air-traffic management software, and last-mile logistics infrastructure, potentially tightening supply and raising competitive pressure across the drone ecosystem. What to watch next is whether Serbia’s Elbit factory moves from announcement and visits to measurable production milestones, contract awards, and training pipelines for operators and maintenance crews. For the undersea track, the key indicators are follow-on allied exercises, any public references to Mk 48 handling cadence, and signs of broader interoperability upgrades between US and Royal Navy submarine communities. On the civilian side, monitor Lowe’s rollout metrics—coverage, delivery reliability, regulatory approvals, and unit economics—as these will show how quickly autonomy and operational safety mature. Trigger points include any export-license changes, sanctions or compliance scrutiny related to UAV technology transfer, and shifts in regional air-defense posture that would suggest the drone ecosystem is becoming a strategic factor rather than a commercial project.

Geopolitical Implications

• 01

  Multi-domain modernization links undersea lethality with UAV manufacturing, increasing strategic uncertainty.

• 02

  Israel-Serbia defense-industrial engagement could shift regional bargaining dynamics and posture calculations.

• 03

  Civil autonomy advances may accelerate dual-use capabilities, compressing timelines for military adoption.

Key Signals

• —Production milestones and contract awards for Serbia’s Elbit drone factory.
• —Follow-on US-UK submarine exercises referencing Mk 48 readiness and interoperability.
• —Lowe’s drone delivery rollout KPIs and regulatory approvals as autonomy matures.
• —Any export-control or sanctions scrutiny tied to UAV technology transfer.
