Naval Group's Seaquest M is a 37m steel-hulled surface drone built to run ten days without a crew; weapons come later.

Key takeaway

France wants Seaquest M to prove ten-day uncrewed endurance before it carries weapons.

Naval Group unveiled Seaquest M on 2 November, a 37m steel-hulled medium USV that the French shipbuilder says is built for "10-day increments without human intervention"⁠1. The launch came ahead of Euronaval, the Paris naval defence trade show.

The French Navy has set its priorities for a medium hull in order: endurance, secure communications links and hull durability first, with weapons left to later increments. The US Navy took the opposite route in September, committing to thirty medium hulls in one batch split between three yards. Paris is paying to learn before it buys a fleet; Washington bought the fleet and will learn on it.

Lower down the size range, ENSTA Brest, a French defence engineering school, has opened an EU-funded tender for 7m and 3.5m naval-drone hulls, with bids closing in late November⁠2.

Deep Analysis

In plain English

A medium uncrewed surface vessel is a ship of a few dozen metres that sails without a crew. Computers steer it, and people ashore or on another ship supervise. Naval Group is France's main warship builder. Its new design, Seaquest M, is meant to stay at sea for 10 days at a time. The French Navy wants it to be reliable and well connected before it carries any weapons. ENSTA Brest, a French defence engineering school, is separately buying small drone-boat hulls for research.

Deep Analysis
Root Causes

Endurance drives the hull choice. A drone ship that must sail 10 days without human intervention has to survive weather and wear that a small plastic or aluminium boat cannot, which pushes the design towards steel and a 37m length.

Secure links come before weapons because an armed uncrewed vessel that loses its connection to a human operator is a legal and operational problem. Solving the link first makes later weapon increments easier to clear.

What could happen next?
  • Consequence

    French medium drone ships will enter service unarmed or lightly armed at first.

  • Opportunity

    Small hull and engine suppliers may win ENSTA Brest lots on price.
